Ingredients

For the pasta

12 oz (340 g) pasta (penne, rigatoni, or shells)

For the roasted squash

1 medium butternut squash (about 2–3 lb), peeled, seeded, and cut into 1-inch cubes
2 tbsp olive oil
Salt and black pepper

For the sauce

2 tbsp unsalted butter or olive oil
1 small onion, finely chopped
2 cloves garlic, minced
1/2 tsp dried sage or 1 tbsp fresh chopped sage (optional)
1 cup low-sodium chicken or vegetable broth
1/2 cup milk (dairy or unsweetened plant milk)
1/4 cup grated Parmesan cheese, plus extra for serving (use nutritional yeast for dairy-free)
Pinch of nutmeg (optional)

For garnish

Fresh parsley or sage leaves, chopped
Extra Parmesan or toasted pumpkin seeds (pepitas)

Notes: Use unsalted butter if you want to control salt. If your squash is small, use two.

How to Make Creamy Butternut Squash Pasta

Preheat the oven to 425°F (220°C). Toss the cubed squash with olive oil, salt, and pepper on a baking sheet. Roast until tender and golden, 25–30 minutes. Mini-tip: browning adds sweet, caramelized flavor.
While the squash roasts, bring a large pot of salted water to a boil and cook the pasta until just shy of al dente. Save 1 cup of the pasta water before draining. Why this matters: the starchy water helps loosen the sauce later.
In a large skillet, melt butter over medium heat. Add chopped onion and cook until soft and translucent, about 5 minutes. Stir in garlic and sage and cook 30 seconds until fragrant. Mini-tip: don’t let garlic burn — it turns bitter.
Transfer half the roasted squash to a blender. Add the sautéed onion mixture, broth, and milk. Blend until very smooth. If too thick, add a splash of the reserved pasta water. Why this step matters: blending here creates a silky, creamy sauce without heavy cream.
Pour the sauce back into the skillet and warm gently. Stir in Parmesan, a pinch of nutmeg, and season to taste with salt and pepper. If the sauce is too thick, thin with reserved pasta water a few tablespoons at a time.
Add drained pasta and the remaining roasted squash to the skillet. Toss gently to coat and heat through for 1–2 minutes. Mini-tip: fold in pasta slowly so squash pieces keep their shape and texture.
Serve immediately with chopped parsley, extra Parmesan, or toasted pepitas on top for crunch.

How to Serve Creamy Butternut Squash Pasta

Plate with a sprinkle of Parmesan and chopped fresh parsley for color and brightness.
Add a crisp green salad (lemony vinaigrette cuts the richness) and crusty bread to soak up the sauce.
For a holiday touch, finish with toasted pepitas and a few fried sage leaves.

How to Store Creamy Butternut Squash Pasta

Fridge: Cool to room temperature, store in an airtight container for up to 3–4 days.
Freezer: Place sauce (without pasta) in a freezer-safe container for up to 3 months; thaw overnight in the fridge. You can freeze whole cooked pasta, but texture may soften.
Reheating: Warm the sauce gently on the stove, adding a splash of milk or reserved pasta water to loosen. Stir in freshly cooked pasta or reheat pasta and sauce together over low heat.

Tips to Make Creamy Butternut Squash Pasta

Roast squash well: more browning = more flavor.
Reserve pasta water to adjust sauce consistency.
Blend until very smooth for a silky mouthfeel.
Use fresh Parmesan for the best savory depth.
If using a high-powered blender, blend hot liquids in small batches and vent the lid slightly.

Variation

Gluten-free: Use your favorite gluten-free pasta and check stock labels.
Dairy-free: Swap milk for unsweetened oat milk and use nutritional yeast instead of Parmesan for cheesy flavor.
Add protein: Stir in cooked chicken, Italian sausage, or crispy chickpeas for a heartier meal.

FAQ — Can I use canned squash?

Yes. Pureed canned butternut squash can work in a pinch. Use about 2 cups, and skip roasting. You may need less liquid; add broth slowly to reach the right thickness.

FAQ — How do I make the sauce smoother?

Blend the sauce in a high-speed blender and strain through a fine mesh sieve if you want extra silkiness. Warm slowly and don’t boil after adding milk.

FAQ — Can I make this ahead for a dinner party?

Make the sauce and roast the squash up to 2 days ahead. Reheat the sauce gently and toss with freshly cooked pasta just before serving for the best texture.
