Ingredients for Butternut Squash & Sage Pasta for Cozy Autumn Nights

Exact amounts are in the printable recipe card below — here's what you'll need at a glance.

Main Ingredients

• 1 medium butternut squash (about 2 lbs), peeled and cubed
• 12 oz pappardelle or fettuccine pasta
• 6 tbsp unsalted butter
• 15–20 fresh sage leaves
• 2 cloves garlic, minced
• 1/2 cup freshly grated Parmesan cheese, plus more for serving

Seasonings & Flavors

• 1 tsp salt, plus more for pasta water
• 1/2 tsp freshly ground black pepper
• Pinch of nutmeg

Optional Toppings

• (Optional) Toasted pine nuts
• (Optional) Extra crispy sage leaves
• (Optional) Red pepper flakes

Ingredient Notes

• Butternut squash: Provides natural sweetness and creamy body when roasted. Choose a firm, heavy squash with no soft spots.
• Fresh sage: Infuses the butter with earthy, peppery depth. Dried sage can work in a pinch, but it lacks the same aroma.
• Butter: Browning it adds nuttiness. Use unsalted to control seasoning; salted butter can make the dish too salty.
• Parmesan cheese: Grate it fresh for a smooth melt. Pre-grated cheese often contains anti-caking agents that prevent proper emulsification.
• Pasta water: The starchy liquid is key for a silky sauce. Reserve at least 1 cup before draining.

How to Make Butternut Squash & Sage Pasta for Cozy Autumn Nights Step by Step

Roast the butternut squash

Preheat oven to 400°F (200°C). Toss cubed squash with 1 tablespoon olive oil, 1/2 teaspoon salt, and a pinch of pepper. Spread on a baking sheet in a single layer. Roast 20–25 minutes, flipping halfway, until edges are deep golden and a fork slides in easily. Watch closely after 18 minutes to avoid burning.

Cook the pasta

Bring a large pot of salted water to a boil. Add pasta and cook until just shy of al dente, about 1 minute less than package directions. Reserve 1 cup of starchy pasta water before draining. Drain pasta and set aside.

Make brown butter sage sauce

While pasta cooks, melt butter in a large skillet over medium heat. Add sage leaves and cook, swirling the pan occasionally, until butter turns golden amber and sage leaves are crisp, 3–5 minutes. Use a slotted spoon to transfer sage leaves to a paper towel. Add minced garlic to the butter and cook 30 seconds until fragrant. Remove skillet from heat.

Combine and emulsify

Add drained pasta to the skillet with the brown butter. Toss with a splash of reserved pasta water and sprinkle in Parmesan cheese. Toss vigorously off heat until a glossy sauce coats the noodles. If it seems dry, add more pasta water 1 tablespoon at a time.

Add squash and serve

Gently fold in roasted squash. Taste and adjust salt and pepper. Serve immediately in warm bowls. Top with crispy sage leaves, extra Parmesan, and optional toppings.

Pro Tips for the Best Butternut Squash & Sage Pasta for Cozy Autumn Nights

• Ingredient prep: Dry the squash cubes well after peeling and before roasting. Excess moisture steams the squash instead of caramelizing it.
• Common mistake and fix: Overcooking the squash results in mush. Roast until just fork-tender with golden edges, checking at 18 minutes. If overdone, it will disintegrate in the pasta.
• Timing: Drop the pasta into the boiling water when the squash has about 10 minutes left. This way, everything finishes at the same time.
• Texture enhancement: For the crispiest sage, fry leaves until they stop sizzling and feel rigid when lifted with tongs. Drain on paper towels immediately.

Storing and Reheating Butternut Squash & Sage Pasta for Cozy Autumn Nights

Refrigerator Storage

Store leftovers in an airtight container for up to 3 days. The pasta will absorb sauce, so add a splash of water or broth when reheating.

Freezing Butternut Squash & Sage Pasta for Cozy Autumn Nights

Freezing is not ideal—the sauce may separate and squash becomes mushy. If needed, freeze in a freezer-safe container up to 1 month. Thaw overnight in the fridge.

Reheating in the Oven

Reheat in a 350°F oven for 15–20 minutes. Add a tablespoon of water or milk to restore creaminess, and cover with foil to prevent drying.

Reheating in the Microwave

Microwave at 50% power for 1–2 minutes, stirring halfway. Add a teaspoon of milk and a tiny pat of butter to revive the sauce.

Make Ahead

Roast squash up to 2 days ahead and store in the fridge. Fry sage leaves and store in an airtight container at room temperature. Cook pasta and assemble sauce just before serving.

Frequently Asked Questions about Butternut Squash & Sage Pasta for Cozy Autumn Nights

Can I use frozen butternut squash for this recipe?

Yes, but thaw the squash completely and pat it very dry with paper towels. Excess moisture will make the pasta watery and prevent caramelization. Roast it a few minutes longer to drive off any remaining liquid. The texture will be slightly softer than fresh, but it still tastes great.

How do I make Butternut Squash & Sage Pasta vegan?

Swap butter with a high-quality vegan butter that browns well, like Miyoko's. Replace Parmesan with nutritional yeast or a vegan Parmesan alternative. The technique remains the same—roast squash until caramelized and use pasta water for creaminess. You'll lose some nutty depth but keep the savory notes.

Why is my pasta sauce watery?

This usually happens when the squash isn't roasted long enough. Undercooked squash releases liquid into the sauce. Roast until the cubes are deeply golden all over and a fork pierces them with zero resistance. Also, add pasta water gradually—too much at once can thin the sauce.

Can I make this ahead for a dinner party?

Partially. Roast the squash and fry the sage leaves a day ahead. When guests arrive, cook the pasta fresh and whip up the brown butter sauce in 10 minutes. Assembling last minute ensures the pasta stays perfectly coated and the squash doesn't get mushy from reheating.

What's the best pasta shape for this dish?

Wide, flat noodles like pappardelle or fettuccine work best because they catch the buttery sauce and pieces of squash. Short shapes like rigatoni or orecchiette are fine too, but they don't hold the sauce as elegantly. Choose a pasta with ridges to grip the glossy emulsion.
