Sausage and butternut squash pasta pairs savory sausage with sweet squash for a satisfying fall dinner. Here’s a pasta recipe worth twirling your fork into!!

If sausage and butternut squash pasta is on your fall cooking list, make this version when you want pasta that tastes rich and creamy without turning into a bowl of heavy sauce.

What Does Sausage and Butternut Squash Pasta Taste Like?

Think of this as a savory fall pasta first and a squash pasta second. Butternut squash brings gentle sweetness and a buttery texture, but browned Italian sausage keeps everything firmly in savory territory.

Parmesan adds saltiness and nutty flavor, fresh sage gives sauce that unmistakable earthy aroma, garlic adds warmth, and red pepper flakes stop all those richer flavors from becoming flat.

I recommend mild Italian sausage if you are cooking for several people because you can control heat yourself with red pepper flakes. If everyone at your table likes a little fire, hot Italian sausage works beautifully too.

Ingredients

For Roasted Butternut Squash

• 1 1/2 pounds peeled and seeded butternut squash, about 4 packed cups cut into 3/4 inch cubes

Cut squash fairly small. Aim for cubes around 3/4 inch. Larger pieces take longer to roast and can stay firm in their centers while smaller pieces caramelize beautifully in about 25 to 30 minutes.

• 1 1/2 tablespoons olive oil
• 1/2 teaspoon kosher salt
• 1/4 teaspoon freshly ground black pepper

For Pasta and Sauce

• 12 ounces rigatoni, mezze rigatoni, penne, or another short pasta with ridges
• 1 pound Italian sausage, casings removed if using links

Use enough sausage. One pound sausage to 12 ounces pasta might sound generous, but it is exactly what keeps this from tasting like noodles covered in squash purée. Once sausage is browned and crumbled, it spreads through several servings nicely.

• 8 fresh sage leaves

Please use fresh sage if you can find it! Dried sage has its place, but fresh sage fried briefly in sausage drippings becomes crisp around its edges and perfumes hot oil in a way dried herbs simply cannot copy.

• 1 medium shallot, finely chopped
• 3 large garlic cloves, finely minced
• 1/4 teaspoon crushed red pepper flakes, plus more if you like extra heat
• 1 cup low sodium chicken broth
• 1/3 cup heavy cream

Keep cream restrained. One third cup is enough. Squash already creates body, so pouring in a cup of cream only hides flavors we spent time developing.

• 3/4 cup finely grated Parmesan cheese, plus more for serving

Grate Parmesan finely. Finely grated cheese melts into warm sauce instead of sitting there in little rubbery clumps wondering why it was invited.

• 1 teaspoon fresh lemon juice
• 1 to 1 1/2 cups reserved pasta water, as needed
• Kosher salt, as needed
• Freshly ground black pepper, as needed

Servings: 5 generous servings

How to Make Sausage and Butternut Squash Pasta

Heat oven to 425°F and line a large rimmed baking sheet with parchment paper if you want easier cleanup. Toss squash cubes with olive oil, 1/2 teaspoon kosher salt, and black pepper, then spread them into one layer with a little breathing room between pieces.

If squash is piled on top of itself, it steams rather than roasts, and we want browned edges here! Roast for 25 to 30 minutes, flipping pieces around 18 minute mark, until squash is completely tender inside and several edges have turned golden brown.

While squash roasts, bring a large pot of generously salted water to a boil. Add pasta and cook until about 1 minute shy of al dente according to package timing. Before draining, scoop out at least 1 1/2 cups pasta water.

I usually put a measuring cup beside my colander before pasta even goes into water because otherwise this is exactly when my brain decides pasta water never existed until I have already poured it down sink.

While pasta cooks, place a large, deep skillet over medium high heat. Add sausage and let it sit untouched for roughly 2 minutes before breaking it apart with a wooden spoon.

That first little pause matters because sausage touching hot pan develops browned edges instead of immediately releasing all its moisture.

Continue cooking for 6 to 8 minutes total, breaking it into bite size crumbles, until well browned and cooked through. Transfer sausage to a plate but leave about 1 tablespoon rendered fat in skillet.

Lower heat to medium. Add sage leaves and cook for roughly 30 to 45 seconds per side, just until leaves darken slightly and become crisp. Watch closely because sage can move from fragrant to charcoal faster than anyone deserves. Transfer leaves to a small plate.

Add chopped shallot to skillet and cook for 2 to 3 minutes, stirring often, until softened. Add garlic and red pepper flakes and cook for another 30 to 45 seconds. As soon as garlic smells fragrant, move on.

You are not trying to brown garlic because browned garlic quickly becomes bitter and can overpower sweet squash.

When squash is ready, set aside roughly 1 1/2 cups roasted cubes. Add remaining roasted squash to a blender with chicken broth and blend until completely smooth.

If your blender struggles, add a few tablespoons of reserved pasta water. You are looking for a thick, pourable purée similar to a creamy soup rather than mashed potatoes.

Pour squash mixture into skillet with shallot and garlic, then stir in heavy cream. Bring it to a very gentle simmer over medium low heat for 2 minutes.

Avoid aggressive boiling once cream goes in because gentle heat keeps texture smoother and gives you more control over sauce thickness.

Add drained pasta and browned sausage to skillet, then pour in 1/2 cup pasta water. Toss everything over medium low heat for 1 to 2 minutes, letting pasta finish cooking directly in sauce. This little finishing period is important.

Pasta releases a bit more starch while sauce works its way into ridges and hollow centers, which makes sauce taste integrated rather than simply poured over noodles.

Turn heat to low and add Parmesan gradually while tossing constantly. Do not dump every bit of cheese into bubbling sauce at once.

Parmesan melts much more smoothly when heat is gentle and cheese is added in a few small handfuls. If sauce becomes too thick, add pasta water about 2 tablespoons at a time until it coats pasta in a glossy layer.

You should be able to drag a spoon through skillet and see sauce slowly flow back into its path.

Fold reserved roasted squash cubes through pasta gently so they stay mostly intact. Add lemon juice, then taste before adding extra salt.

Sausage and Parmesan both bring plenty of salt, so this is one of those moments when tasting saves dinner from enthusiastic seasoning. Add black pepper and another pinch of red pepper flakes if you want more heat.

Crumble crisp sage over pasta just before serving and finish with another light shower of Parmesan. Eat it while sauce is still silky and hot because creamy pasta waits for no one, not even whoever suddenly decided now was a good time to reorganize kitchen cabinets.

How to Tell When Your Sauce Is Just Right?

Sauce should cling to each piece of pasta without pooling heavily at bottom of skillet. If you lift a piece of rigatoni, you should see a shiny orange coating rather than a thick mound of squash.

• If sauce looks pasty, add warm pasta water a couple tablespoons at a time.
• If it looks watery, keep pasta over low heat for another minute while tossing.
• If flavor tastes too sweet, add another teaspoon of lemon juice, a pinch of red pepper, or a little Parmesan.
• If sauce tastes flat, check salt before adding anything else. Often that is all it needs.

Serving Suggestions

Serve this sausage and butternut squash pasta straight from skillet with plenty of Parmesan and a little cracked black pepper. Because pasta is already rich and full flavored, simpler sides work best.

A crisp arugula salad dressed with lemon juice and olive oil is probably my favorite pairing because peppery greens cut nicely through creamy sauce. A shaved Brussels sprout salad works particularly well during cooler months, too.

For vegetables, try roasted broccoli, garlicky green beans, or simple roasted Brussels sprouts. Their slightly bitter, savory flavors contrast nicely with sweet squash.

If you want bread, go for warm crusty bread or garlic bread and use it to catch any sauce left on your plate. Nobody needs to pretend that part is beneath them.

How to Store and Reheat Leftovers

Store leftovers in an airtight container in refrigerator for up to 3 days.

For best texture, reheat pasta gently in a skillet over medium low heat with a splash of water or chicken broth. Start with about 2 tablespoons liquid per serving, toss as pasta warms, then add another splash if needed.

A microwave works too. Add a teaspoon or two of water, cover loosely, heat for about 60 seconds, stir, then continue in 20 to 30 second bursts until hot.

Avoid reheating over very high heat because cream and Parmesan sauce can separate while pasta dries around its edges.

Easy Variations!

• For a little more heat, use hot Italian sausage and increase red pepper flakes.
• For extra greens, stir in 3 packed cups baby spinach during final minute of cooking. It wilts almost immediately.
• For a smokier flavor, replace half Italian sausage with diced pancetta, but reduce added salt until you taste finished sauce.
• If you cannot find fresh sage, use about 1 teaspoon finely chopped fresh rosemary instead. Rosemary is stronger, so a little goes a long way.
• For a slightly lighter sauce, replace heavy cream with half and half. Keep heat gentle once it goes into skillet.

This sausage and butternut squash pasta is exactly what I want when cooler weather makes a bowl of pasta sound especially good: sweet roasted squash, browned sausage, fragrant sage, plenty of Parmesan, and a silky sauce that grabs every ridge of rigatoni.

Make it once and pay attention to those browned squash edges and little crispy pieces of sausage as you eat. Those are going to be first things you hunt for next time!
