Slow Cooker Thanksgiving Sides

1. Slow Cooker Brown Butter Parsnip-Potato Mash with White Miso

Yukon Gold potatoes give this mash its creamy texture, while parsnips add gentle sweetness and a slightly earthy flavor that works beautifully with nutty brown butter.

A small spoonful of white miso adds fermented, salty depth without making every bite taste strongly of miso, and crisp shallots give those soft potatoes a welcome little crunch.

I would keep this mash slightly rustic, with a few tiny potato pieces and plenty of buttery swirls, rather than working it until perfectly smooth.

Thanksgiving already provides enough opportunities to worry about appearances, and a harmless potato lump does not need to become another one!

Servings: 8

Hands-on time: About 25 minutes
Slow cooking: 3½ to 4½ hours on HIGH or 6 to 7 hours on LOW
Slow cooker: 4 quarts

Ingredients

• 2 pounds Yukon Gold potatoes, peeled and cut into 1-inch pieces
• 1 pound parsnips, peeled and cut into ½-inch pieces, with any thick, woody centers removed
• 4 garlic cloves, peeled and left whole
• 1 cup low-sodium vegetable broth
• ½ teaspoon fine sea salt, plus more to taste
• 5 tablespoons unsalted butter
• ¾ cup whole milk, plus a little more only if needed
• 1 tablespoon white miso paste
• ¼ teaspoon freshly ground black pepper
• ⅓ cup packaged crispy fried shallots
• 2 tablespoons finely chopped fresh chives

How to Make It

1. Put potatoes, parsnips, garlic, broth, and salt into your slow cooker, then stir just enough to distribute everything evenly. Cut parsnips smaller than potatoes because their firmer texture can take longer to soften, particularly when larger roots have a dense center.

Broth will not cover these vegetables, which is intentional; cooking happens with a combination of heat, moisture, and trapped steam.

2. Cover and cook on HIGH for 3½ to 4½ hours or LOW for 6 to 7 hours, checking at the earlier end of your chosen range. Pierce several pieces from different areas with a small knife, including a parsnip near the center, and keep cooking if you feel resistance.

Don’t rush this step: vegetables that are only barely tender will give you stubborn little pieces that extra milk cannot fix.

3. About 15 minutes before you expect to mash, melt butter in a small, light-colored saucepan over medium-low heat, swirling frequently for roughly 4 to 7 minutes. It will foam before small brown specks appear underneath.

Once those specks turn golden brown and butter smells nutty, immediately pour it into a heatproof bowl, including all those flavorful browned bits. If it smells sharp or looks black, it has gone too far and needs replacing.

4. Warm milk in that saucepan over low heat until steaming gently, without letting it boil, then whisk miso into ½ cup of warm milk until smooth. Lift cooked vegetables into a large bowl with a slotted spoon, reserving cooking liquid separately, and mash with a hand masher.

Add browned butter, miso milk, and pepper, then fold and mash gently until everything comes together; avoid a blender or food processor, which can turn potatoes gluey.

5. Add remaining warm milk a tablespoon or two at a time until mash falls softly from your spoon, using a little reserved cooking liquid if you want it looser still. Taste before adding more salt because miso and broth already contribute seasoning, then serve immediately or return mash to your emptied slow cooker on a verified WARM setting.

Sprinkle crispy shallots and chives over individual servings or across your serving bowl just before dinner so every bite keeps some crunch!

Serving Suggestions

Serve beside herb-roasted turkey, roast chicken, or mushroom gravy, leaving a shallow dip in each spoonful to catch a little sauce. I would offer extra crispy shallots in a small bowl, since they tend to disappear well before anyone admits to taking more.

2. Slow Cooker Apple Butter Sweet Potatoes with Rye-Walnut Crunch

Tender orange sweet potatoes get a glossy coating of apple butter, a restrained pinch of smoked paprika, and just enough cider vinegar to keep their natural sweetness lively.

Toasted rye crumbs, chopped walnuts, and sage add a crisp finish that tastes especially good against those soft centers, without needing a layer of marshmallows.

My preference is a coarse topping with visible walnut pieces, because tiny crumbs disappear too easily against soft vegetables. 

Servings: 8

Hands-on time: About 25 minutes
Slow cooking: 3 to 4 hours on HIGH or 5 to 6 hours on LOW
Slow cooker: 4 quarts

Ingredients

• 3 pounds orange-fleshed sweet potatoes, peeled and cut into 1½-inch chunks
• ½ cup unsweetened apple cider, not hard cider or apple cider vinegar
• 3 tablespoons unsalted butter, divided
• ¾ teaspoon fine sea salt, divided
• ⅓ cup apple butter, preferably a lightly spiced variety
• ½ teaspoon smoked paprika
• 1½ teaspoons apple cider vinegar, plus more to taste
• ¾ cup coarse fresh rye breadcrumbs, made from about 1 large slice of rye bread
• ½ cup walnuts, chopped into small pieces
• 1 teaspoon finely chopped fresh sage

How to Make It

1. Add sweet potato chunks and apple cider to your slow cooker, then scatter 2 tablespoons of butter in small pieces over them and sprinkle with ½ teaspoon salt. Keep chunks close to the same size so smaller pieces do not collapse while larger ones are still firm, and give everything one gentle turn with a spoon before covering.

2. Cook on HIGH for 3 to 4 hours or LOW for 5 to 6 hours, checking a few pieces at the earlier end of that range. A thin knife should slide through their centers easily, but pieces should still hold together when lifted with a spoon.

Once they reach that point, move ahead with finishing; leaving them cooking simply because dinner is later will make them more likely to fall apart.

3. While sweet potatoes finish, melt remaining tablespoon of butter in a skillet over medium-low heat and add rye crumbs and walnuts. Stir frequently for 5 to 8 minutes, adjusting heat downward if nuts darken before breadcrumbs feel dry and crisp, then add sage and remaining ¼ teaspoon salt for the final 30 seconds.

Spread topping on a plate to cool uncovered, which helps it stay crisp instead of trapping steam in a bowl.

4. Lift cooked sweet potatoes into a warm serving bowl with a slotted spoon, taking care not to break their edges, and reserve 3 tablespoons of cooking liquid. Whisk that liquid with apple butter, smoked paprika, and cider vinegar in a small bowl until you have a thick, pourable glaze.

Apple butter varies in sweetness, so taste a little glaze with a piece of sweet potato before deciding whether another ½ teaspoon vinegar would improve it.

5. Spoon glaze over hot sweet potatoes and fold very gently with a wide silicone spatula, stopping as soon as most pieces look coated. Scatter rye-walnut crunch on top immediately before serving, keeping a little extra on the side.

Don’t add this topping before holding or covering the dish: moisture will soften those carefully toasted crumbs, and they deserve their brief moment of glory!

Serving Suggestions

These sweet potatoes work especially well with turkey, baked ham, or a mushroom Wellington, since smoky apple flavor complements browned meat and earthy mushrooms.

Serve in a shallow bowl so more pieces get a share of topping, rather than letting all that crunch settle over just a few spoonfuls.

3. Slow Cooker Smoked Gouda Creamed Corn with Scallions and Pickled Jalapeños

Sweet corn, soft cream cheese, and smoked Gouda make a thick, creamy side with a gentle smoky finish, while scallions and chopped pickled jalapeños add freshness and a little tangy heat.

Blending a small portion of corn into milk helps thicken everything naturally, so you get a sauce that clings to kernels without needing a separate flour mixture.

I would start with a modest amount of jalapeño, taste, and let heat-loving guests add more at dinner. Somebody always says they enjoy spicy food just before discovering that everyone has a rather different definition of spicy!

Servings: 8

Hands-on time: About 15 minutes
Slow cooking: 2½ to 3½ hours on LOW, plus 5 to 10 minutes to melt Gouda
Slow cooker: 3 quarts

Ingredients

• 2 pounds frozen sweet corn, thawed completely in the refrigerator and drained, about 6 cups
• ¾ cup whole milk, plus a little warm milk for adjusting consistency
• 6 ounces full-fat block cream cheese, cut into 1-inch cubes
• 1 tablespoon unsalted butter
• 3 scallions, thinly sliced, with white and green parts kept separate
• ¼ teaspoon fine sea salt, plus more only if needed
• ¼ teaspoon freshly ground black pepper
• 3 ounces smoked Gouda, rind removed and cheese freshly shredded, about ¾ cup
• 2 tablespoons finely chopped pickled jalapeños, drained, divided

How to Make It

1. Drain thawed corn well, since ice crystals and thawing liquid can make your finished sauce thinner than intended. Put 1 cup corn into a blender with milk and blend until mostly smooth, stopping to scrape down once if necessary; a few tiny corn flecks are fine, so you do not need to keep blending until it resembles a perfectly smooth soup.

2. Add remaining corn to your slow cooker along with blended corn mixture, cream cheese, butter, scallion whites, salt, and pepper. Stir to distribute cream cheese cubes, cover, and cook on LOW for 2½ to 3½ hours. Use LOW for this recipe because a dairy mixture can catch around hot edges before its center is ready on HIGH.

3. After about 90 minutes, stir once, drawing corn from the outer edge toward the middle and gently breaking up softened cream cheese with your spoon, then replace the lid promptly.

Continue until corn is steaming hot throughout, cream cheese has melted completely, and sauce looks smooth after stirring. Begin checking around 2½ hours, allowing more time if your cooker heats slowly.

4. Switch to WARM and fold in shredded Gouda a small handful at a time, letting each addition soften before adding more. Cover for 5 to 10 minutes if needed, then stir in 1 tablespoon jalapeños and most scallion greens. Keep cheese sauce below a vigorous simmer once Gouda is added, which helps preserve a smoother texture.

5. Taste a spoonful after it has cooled slightly, then decide whether to add remaining jalapeños or a small pinch of salt. If corn feels thicker than you like, stir in warm milk 1 tablespoon at a time.

It should settle slowly from a serving spoon, with creamy sauce coating kernels rather than collecting separately underneath. Finish with remaining scallion greens and serve while warm and creamy!

Serving Suggestions

Spoon beside roast turkey, smoked turkey, or a peppery roast pork loin, and add a crisp green salad if several other sides are especially rich.

Extra chopped jalapeños make a useful optional garnish, while a warm dinner roll is excellent for catching any cheese sauce left on your plate.

4. Slow Cooker Pomegranate Red Cabbage with Dates and Orange

This red cabbage cooks into silky ribbons with a gently sweet, tangy flavor from pomegranate juice, chopped dates, and cider vinegar.

A little ground coriander brings a warm citrus note, and fresh orange zest added at the end keeps every mouthful fragrant rather than letting long cooking flatten those brighter flavors.

I would include this whenever your menu has plenty of butter, cheese, or gravy, because its acidity gives each rich mouthful a pleasant change of pace.

Ruby-colored cabbage also looks lovely beside pale potatoes, which appreciate a little help making your plate look festive!

Servings: 8

Hands-on time: About 20 minutes
Slow cooking: 3 to 4 hours on HIGH or 6 to 7 hours on LOW
Slow cooker: 5 to 6 quarts

Ingredients

• 2 pounds red cabbage, weighed after removing outer leaves and core, sliced into ¼-inch ribbons
• 1 medium yellow onion, peeled and thinly sliced
• ½ cup 100% pomegranate juice, unsweetened
• ¼ cup water
• 3 tablespoons apple cider vinegar, plus more to taste
• 2 tablespoons olive oil
• ⅓ cup pitted dates, finely chopped, about 2 ounces
• 1 teaspoon fine sea salt
• ½ teaspoon ground coriander
• ¼ teaspoon freshly ground black pepper
• 1 teaspoon finely grated orange zest
• 2 tablespoons chopped flat-leaf parsley
• ⅓ cup pomegranate arils, optional, for serving

How to Make It

1. Cut cabbage into quarters, remove its firm core, and slice across each quarter to make ribbons about ¼ inch wide. Separate any thick clumps with your fingers before adding cabbage and onion to your slow cooker, because tightly packed pieces can stay firmer than surrounding strands.

If your pot looks overly crowded, move to a larger recommended capacity instead of pressing everything down against the lid.

2. Whisk pomegranate juice, water, vinegar, olive oil, salt, coriander, and pepper in a measuring jug, then stir in finely chopped dates. Pour over cabbage and use two large spoons to turn everything gently, bringing some liquid and dates up through those top layers.

Dates soften into small sweet pieces during cooking, so chopping them finely gives a more even flavor than leaving large sticky chunks.

3. Cover and cook on HIGH for 3 to 4 hours or LOW for 6 to 7 hours, turning cabbage once around halfway through if you are nearby. At the earlier end of your cooking range, taste a cooled strand from the center.

It should bend easily and feel tender all the way through, with no thick, crunchy middle. If it still seems tough, cover and continue in 20- to 30-minute increments.

4. Stir in orange zest once cabbage is tender, then taste a bite before adjusting seasoning. Add another teaspoon of vinegar if you want a sharper finish, or a pinch of salt if flavor seems muted, keeping in mind that dates contribute sweetness as you chew.

Don’t add orange zest at the start: its fresh fragrance is much more noticeable when you save it for finishing.

5. Lift cabbage into a warm serving bowl with a slotted spoon, adding just enough cooking juices to keep strands glossy and moist. Slow cookers retain liquid, so leaving excess juice behind is perfectly fine and prevents it from spreading across everybody’s plate.

Scatter parsley and optional pomegranate arils over the top immediately before serving for little fresh bursts against those soft ribbons.

Serving Suggestions

Serve alongside roast turkey, duck, pork tenderloin, or a nut roast, with mashed potatoes nearby to balance its gentle acidity.

This is also a useful choice when cranberry sauce already has plenty of sweetness, since you can adjust vinegar at the end to keep cabbage pleasantly tart.

5. Slow Cooker White Beans with Fennel, Chestnuts, and Sage

Cannellini beans turn creamy around their edges while keeping tender centers, fennel softens into a mellow, lightly sweet vegetable, and cooked chestnuts add soft, nutty pieces throughout.

Sage and a little Parmesan bring enough richness to make this feel special, while lemon added at the end keeps it from tasting heavy.

My preference is to mash only a small portion of beans into their broth, which gives you a thick spoonable sauce while leaving most beans intact.

Chestnuts are softer and starchier than walnuts or pecans, so expect tender bites here rather than crunch, and choose plain cooked chestnuts instead of sweetened ones.

Servings: 8

Hands-on time: About 25 minutes
Slow cooking: 1½ to 2½ hours on HIGH or 3 to 4 hours on LOW
Slow cooker: 4 quarts

Ingredients

• 2 tablespoons olive oil
• 12 ounces trimmed fennel bulbs, halved, cored, and sliced ¼ inch thick, about 3 cups
• 1 medium yellow onion, finely chopped
• 3 garlic cloves, minced
• 2 teaspoons finely chopped fresh sage
• 1 teaspoon fresh thyme leaves
• 3 cans cannellini beans, 15 ounces each, drained and rinsed
• 6 ounces plain peeled, fully cooked chestnuts, roughly chopped
• 1 cup low-sodium vegetable broth
• ½ teaspoon fine sea salt, plus more to taste
• ¼ teaspoon freshly ground black pepper
• ½ cup finely grated Parmesan, about 1½ ounces
• 1 teaspoon finely grated lemon zest
• 1 tablespoon fresh lemon juice, plus more to taste
• 2 tablespoons chopped fennel fronds or flat-leaf parsley

How to Make It

1. Heat olive oil in a large skillet over medium heat, then add sliced fennel and chopped onion with a small pinch taken from your measured salt. Cook for 10 to 12 minutes, stirring regularly, until onion looks translucent and fennel starts softening with a few golden edges.

If browning happens before vegetables soften, lower heat slightly and add 1 tablespoon water to loosen anything sticking underneath.

2. Stir in garlic, sage, and thyme for 30 to 60 seconds, just until fragrant, then scrape vegetables and any flavorful pan juices into your slow cooker. Don’t skip this short stovetop step: fennel needs a head start so it becomes tender without requiring hours of extra cooking after canned beans are already soft.

3. Add drained beans, chestnuts, broth, remaining salt, and pepper, then fold gently with a wide spoon. Cover and cook on HIGH for 1½ to 2½ hours or LOW for 3 to 4 hours, checking at the earlier end of the range.

Fennel should yield easily when pressed with a fork, beans should be hot throughout, and chestnuts should feel tender without requiring you to chew around hard pieces.

4. Scoop about ½ cup beans and a few spoonfuls of broth into a small bowl, mash with a fork, and return this mixture to your cooker. Fold gently and let it settle for a minute before deciding whether you want a thicker sauce.

You can mash another small spoonful if needed, but keep plenty of whole beans for texture. If mixture seems too thick instead, loosen it with hot water 1 tablespoon at a time.

5. Switch to WARM, stir in Parmesan until melted, and finish with lemon zest, lemon juice, and chopped fronds or parsley.

Taste before adding more salt, since Parmesan contributes plenty, and add an extra teaspoon lemon juice only if you want a brighter finish. You should have creamy beans that hold softly on a spoon, with enough sauce to keep every bite moist.

Serving Suggestions

Serve in shallow bowls beside roast turkey, chicken, or roasted mushrooms, finishing each portion with a little extra fennel frond if available.

Crusty bread makes a good companion for any remaining bean sauce, and a spoonful of tart cabbage works particularly well alongside.

6. Slow Cooker Artichoke, Leek, and Fontina Stuffing

Sourdough absorbs buttery leek flavor while keeping enough structure for distinct, tender bread pieces, and artichoke hearts add a gentle tang that makes this stuffing especially good with rich gravy.

Fontina melts through it in soft pockets, while thyme, parsley, and a small amount of lemon zest keep those creamy flavors lively.

I would choose this for guests who enjoy traditional bread stuffing but would welcome something a little different from sausage and dried fruit.

Expect a moist center and some browned edges where bread touches your cooker, with a soft top rather than an oven-crisp crust, which is a perfectly reasonable trade when your turkey has claimed most of your oven!

Servings: 8 to 10

Hands-on time: About 35 minutes
Bread drying: 45 to 60 minutes at 250°F / 120°C, which can be done a day ahead
Slow cooking: About 3 to 4 hours on LOW, followed by 10 minutes resting
Slow cooker: 6 quarts

Ingredients

• 1 pound sourdough bread, weighed before drying and cut into ¾-inch cubes, about 10 to 12 loosely measured cups
• 5 tablespoons unsalted butter, divided
• 2 medium leeks, white and light green parts only, thinly sliced, about 3 cups
• 2 celery stalks, finely chopped, about 1 cup
• 2 garlic cloves, minced
• 1 can artichoke hearts packed in water, 14 ounces, drained thoroughly and roughly chopped
• 2 teaspoons fresh thyme leaves
• 2 tablespoons chopped flat-leaf parsley
• 1 teaspoon finely grated lemon zest
• ½ teaspoon fine sea salt
• ½ teaspoon freshly ground black pepper
• 2 large eggs
• 2 cups low-sodium vegetable or chicken broth, plus up to ½ cup more as needed
• 4 ounces fontina, rind removed and cheese cut into small cubes, about 1 cup

How to Make It

1. Spread bread cubes across two rimmed baking sheets and dry them at 250°F / 120°C for 45 to 60 minutes, turning halfway through, until a cooled cube feels dry in its center rather than soft or springy.

You are drying bread rather than trying to brown it deeply, so reduce heat slightly if edges color too quickly. If doing this a day ahead, let cubes cool completely before storing airtight at room temperature.

2. Swish sliced leeks in a bowl of cold water to loosen trapped grit, then lift them out rather than pouring sandy water back over them, and drain well. Melt 4 tablespoons butter in a large skillet over medium-low heat, add leeks and celery, and cook for 10 to 12 minutes until softened, stirring occasionally.

Add garlic and thyme for another minute, then remove from heat and let vegetables cool until warm rather than piping hot.

3. Pat drained artichokes thoroughly dry with paper towels before chopping, giving them a gentle squeeze if water remains between their leaves. Put dried bread in a very large bowl with cooked vegetables, artichokes, parsley, lemon zest, salt, pepper, and fontina, then toss gently to distribute everything.

Don’t skip drying artichokes: extra liquid hidden inside them can make a few mouthfuls much wetter than others.

4. Whisk eggs with 2 cups broth until evenly combined, pour over bread mixture in two additions, and fold gently between pours. Let mixture stand for 5 minutes so bread can absorb moisture, then break open a cube with clean fingers.

Its center should feel moistened, and it should compress without turning to paste. If centers remain dry, add reserved broth 2 tablespoons at a time, stopping before liquid starts pooling underneath.

5. Grease your slow cooker with remaining tablespoon of butter, reaching a little way up its sides, then spoon in stuffing without pressing it into a dense layer. Cover and cook on LOW for about 3 to 4 hours, beginning to check after 3 hours.

Insert a food thermometer into several spots around the center and continue cooking until stuffing reaches 165°F / 74°C throughout; brown edges alone do not tell you whether its middle is ready. This follows the safe temperature guidance for casseroles.

6. Once cooked, switch off and let stuffing rest uncovered for 10 minutes before serving, which allows excess surface steam to escape and makes portions easier to lift. Use a broad serving spoon to collect both soft middle pieces and a few browned edges from around the sides.

If dinner is delayed, use a verified WARM setting instead, keeping stuffing covered until that final short rest.

Serving Suggestions

Serve with roast turkey and a little gravy, adding sauce at the table so bread keeps its texture.

A spoonful of pomegranate cabbage or a crisp leafy salad provides a useful contrast to buttery leeks and melted fontina, especially when mashed potatoes are coming around too.

A Few Make-Ahead Details That Make Dinner Easier!

• Dry stuffing bread and chop firm vegetables a day ahead, refrigerating prepared vegetables in separate containers.
• Keep stuffing’s dry bread separate from its egg and broth mixture until you are ready to cook, and prepare crisp toppings ahead only if you can cool them completely and keep them airtight.
• A topping that is still warm when you close its container will trap steam and soften.
• If you cook a side ahead, divide it into shallow containers and refrigerate promptly, within two hours, keeping your refrigerator at 40°F / 4°C or colder. Use refrigerated leftovers within three to four days.
• Reheat on the stovetop, in a microwave, or in an oven until food reaches 165°F / 74°C, then transfer to a preheated slow cooker if you want to hold it hot for serving; do not use a slow cooker to reheat cold leftovers. 

With creamy miso mash, glossy apple butter sweet potatoes, and bright pomegranate cabbage to choose from, these slow cooker Thanksgiving sides give you plenty of delicious reasons to make a little extra room on your holiday plate.

Choose a favorite, save those crunchy toppings for the last moment, and bring each dish to dinner while its butter, herbs, and warm spices still smell wonderful.

A second spoonful is entirely understandable!
