Hosting a smaller holiday meal? Make crockpot turkey tenderloin the centerpiece, with a slow cooker recipe to inspire your Thanksgiving dinner menu!

Tender slices of crockpot turkey tenderloin, a glossy ribbon of apple cider Dijon gravy, and mashed potatoes waiting underneath sound like an excellent reason to clear your evening calendar!

What Makes This Recipe Special?

This turkey is meant to be sliced into moist, tender pieces, with browned edges and a sauce that tastes layered without needing a long shopping list. Apple cider adds fruitiness, Dijon keeps that sweetness in check, and sage butter brings a toasted, almost nutlike aroma.

My strongest recommendation is to give gravy its own few minutes on your stovetop after turkey finishes, because reducing or thickening sauce while lean meat keeps cooking is an easy way to overshoot juicy.

Ingredients

For Turkey and Cooking Liquid

• 1 1/2 pounds turkey breast tenderloins, about 680 g: Usually 2 tenderloins weighing roughly 12 ounces each; choose similarly sized, fully thawed pieces.
• 3/4 teaspoon fine sea salt, about 4.5 g: For unbrined turkey; see seasoning note below.
• 1/2 teaspoon freshly ground black pepper.
• 1 teaspoon dried thyme, rubbed between your fingers to release its fragrance.
• 1 tablespoon plus 1 teaspoon olive oil, divided.
• 1 cup thinly sliced shallots, about 150 g: Usually 3 medium to large shallots, peeled and sliced about 1/8 inch thick.
• 4 garlic cloves, minced.
• 1/2 cup apple cider, 120 ml: Choose unspiced, nonalcoholic cider with no added sugar. This is a drinking cider, not apple cider vinegar!
• 3/4 cup unsalted chicken or turkey broth, 180 ml, plus extra as needed when measuring gravy liquid.
• 1 1/2 tablespoons Dijon mustard, divided: Use 1 tablespoon during cooking and reserve 1
• 1/2 teaspoons for gravy.

For Brown Butter Sage Gravy

• 2 tablespoons unsalted butter, 28 g.
• 6 medium fresh sage leaves, finely chopped, about 2 teaspoons.
• 2 tablespoons all-purpose flour, 16 g.
• 1 1/2 cups strained cooking liquid, 360 ml: Collected after turkey cooks and adjusted with broth if necessary, as explained below.
• Reserved 1 1/2 teaspoons Dijon mustard.
• 1 to 2 teaspoons apple cider vinegar, added gradually to taste.
• Salt and black pepper, only as needed after tasting.
• 1 tablespoon chopped fresh parsley, optional, for serving.

Read your turkey label before reaching for salt. Tenderloins described as enhanced, marinated, or containing a salt solution already bring seasoning to dinner, so omit added salt initially for those products and adjust finished gravy after tasting.

I would choose plain, unseasoned tenderloins when available because they give you more control over this apple, mustard, and herb combination.

• Servings: 4
• Slow cooking: Approximately 2 to 4 hours on LOW, with a first temperature check at 90 minutes
• Total time: Approximately 2 hours 35 minutes to 4 hours 35 minutes

How to Make Crockpot Turkey Tenderloin 

Start with turkey that is completely thawed in your refrigerator, and keep it chilled until you are ready to cook; frozen poultry should not go directly into a slow cooker. Pat both tenderloins thoroughly dry with paper towels, without rinsing them, and trim away any obvious tough, silvery membrane if present.

Mix salt, pepper, and thyme, then sprinkle seasoning evenly over every side, using no added salt if your turkey is already brined. Dry surfaces matter here because wet turkey spends its first few minutes steaming instead of developing that appealing golden color.

Heat a large skillet over medium-high heat for about 2 minutes, then add 1 tablespoon olive oil and swirl it around. When oil shimmers, lay turkey in gently and leave it alone for about 2 minutes per broad side, just until you see golden patches; you are adding flavor, not cooking it through at this stage.

If it sticks, give it another 20 to 30 seconds before trying to lift it, and lower heat if browned bits start turning black. Transfer turkey straight into your slow cooker, arrange pieces side by side without stacking, switch to LOW, and cover while you finish sauce immediately.

Reduce skillet heat to medium, add remaining 1 teaspoon oil and sliced shallots, and cook for 4 to 5 minutes, stirring frequently, until shallots soften and edges turn pale gold. Add garlic and stir for about 30 seconds, stopping before it browns.

Pour in cider and broth, scrape up golden bits with a wooden spoon, and whisk in 1 tablespoon Dijon. Let everything reach a gentle simmer for about 1 minute, then pour sauce and shallots over turkey and replace your slow-cooker lid.

You should have a shallow pool of liquid around meat, so resist adding enough broth to submerge it, which would dilute your future gravy.

Cook on LOW, planning on approximately 2 to 4 hours after adding sauce, but make your first temperature check at 90 minutes because seared, smaller tenderloins can finish sooner.

Keep lid closed between checks, and insert an instant-read thermometer sideways into each piece so its tip reaches the center of its thickest section without touching your crock.

If turkey is still well below 165°F, cover and check again in about 20 to 30 minutes; once it approaches 160°F, shorten that interval to 10 to 15 minutes. A slow-cooker-safe leave-in probe is useful if your model supports one, although you should still verify both pieces before removing them.

Remove each tenderloin as soon as its thickest part reaches 165°F (74°C), using a clean plate or cutting board, and tent loosely with foil.

One piece may finish before another, so let the ready one rest while its thicker companion continues cooking. Do not use color alone to judge doneness or remove poultry early on an assumption that resting will bring it up to temperature.

Aim for a 10- to 15-minute rest while you prepare gravy; this recipe is intended for a shorter slow-cooker session, and leaving lean turkey cooking for an entire workday will work against tender slices!

Carefully strain cooking liquid into a heatproof measuring jug, reserving softened shallots and garlic for serving. You need 1 1/2 cups liquid for your gravy, which gives 2 tablespoons flour a sensible amount to thicken.

If you have less, add unsalted broth to reach that mark; if you have more, simmer liquid in a saucepan until it reduces to 1 1/2 cups, or simply reserve surplus for reheating leftovers if its flavor is already concentrated.

Taste only after turkey has finished cooking, and avoid reducing liquid that already tastes salty. Measuring here is a small step that saves a lot of hopeful whisking later!

Melt butter in a small, light-colored saucepan over medium heat, swirling frequently for about 3 to 5 minutes, until foam begins to settle and milk solids turn golden brown.

Watch specks on your pan’s bottom, since those tell you more than surface foam does, and follow that warm, toasted aroma.

Add chopped sage for the last 20 to 30 seconds, then lower heat and whisk in flour for about 1 minute. Don’t skip watching butter closely, because golden and fragrant can become black and bitter surprisingly quickly; if it burns, wash your pan and start again with fresh butter.

Whisk measured cooking liquid into butter and flour a little at a time, starting with a few tablespoons to make a smooth paste before adding the rest. Bring to a gentle simmer and cook for 3 to 5 minutes, whisking often, until gravy coats the back of a spoon but still pours easily.

Turn off heat and stir in reserved 1 1/2 teaspoons Dijon and 1 teaspoon cider vinegar, then taste. If apple sweetness stands out too much, add remaining vinegar a few drops at a time; if gravy tastes flat, try a small pinch of salt, and if it is thicker than you like, loosen it with broth 1 tablespoon at a time.

You want a rounded apple flavor with a little mustard brightness, not a sauce that makes your cheeks pucker!

Look for the direction muscle fibers run, then slice rested turkey across those fibers into pieces about 1/2 inch thick; cutting this way makes each bite easier to chew.

Stir any collected resting juices into gravy and taste once more, then arrange slices on a warmed platter with reserved shallots and garlic tucked around them. Spoon some gravy over turkey, scatter parsley on top if using, and serve remaining sauce separately.

I would keep slices out of a bubbling cooker at this point, because they have already reached their destination and do not need another lap!

Serving Suggestions

My first choice would be buttery mashed potatoes, because their soft texture catches cider gravy beautifully, alongside roasted green beans or broccoli for a little browned-edge crunch.

A simple arugula salad with lemon and olive oil also works well when you want something fresh and peppery alongside that buttery sauce.

For a smaller Thanksgiving dinner, add stuffing and a tart cranberry relish, then enjoy having oven space left for whichever side dish usually starts a family negotiation!

For an everyday dinner, spoon turkey and gravy over brown rice, wild rice, or mashed cauliflower, and add steamed green beans with lemon. Divide turkey into four portions and offer roughly 1/3 cup gravy per plate, with any extra at the table.

Keep vegetable sides lightly seasoned until you taste everything together, especially if your turkey came pre-brined.

Small Details That Make Dinner Easier

• If you cannot find shallots, use 1 cup thinly sliced yellow onion and cook until softened before adding garlic.
• Plain, unsweetened apple juice can replace cider in the same amount, although its flavor is less rounded; taste before adding extra vinegar.
• If fresh sage is unavailable, use 1/2 teaspoon dried rubbed sage, adding it with flour rather than frying it in butter. These swaps keep you on track without turning dinner into a second grocery trip!
• Cook potatoes and chunky carrots separately, since they may still be firm when small turkey tenderloins reach 165°F. A large turkey breast roast also needs its own timing, so use actual breast tenderloins for this recipe.
• If your cooker is much larger than recommended, follow its minimum-fill guidance and use an appropriately sized appliance instead of trying to correct the fit with several extra cups of broth.

Bring this crockpot turkey tenderloin to your table with a generous spoonful of apple cider Dijon gravy, a pile of potatoes, and something green, and even an ordinary evening gets a delicious upgrade!

Garlic, toasted sage butter, and a little mustard give each tender slice plenty of character, while that careful temperature check helps keep dinner juicy.

Pass extra gravy around early, because once everyone tastes it, that little pitcher is going to have a very busy night!
