How to Make Butternut Squash Pasta Sauce

Step 1: Prepare and Roast the Vegetables

Start by preheating your oven to a high temperature of 450°F (230°C) to ensure a great roast. Toss the diced butternut squash, quartered plum tomatoes, and yellow onion with olive oil, salt, pepper, fresh thyme, and red pepper flakes. Spread everything on a baking sheet in a single layer so they roast evenly. This step caramelizes the veggies, unlocking deep, rich flavors you’ll love.

Step 2: Cook the Pasta

While the vegetables roast, bring a large pot of salted water to a boil and cook your penne pasta according to the package instructions. Don’t forget to reserve about half a cup of the pasta water before draining—it’s the secret ingredient for adjusting the sauce’s consistency later on!

Step 3: Blend the Sauce

Once the roasted vegetables are tender and lightly browned, transfer them into a blender. Add the reserved pasta water and blend until you get a smooth, creamy sauce that’s thick enough to coat every piece of pasta beautifully. This step transforms your roasted veggies into a silky Butternut Squash Pasta Sauce that feels indulgent yet wholesome.

Step 4: Combine and Serve

Pour your luscious sauce over the drained penne pasta, stirring well to ensure each bite is coated with that comforting creaminess. Drizzle with a little extra olive oil and sprinkle generously with vegetarian Parmesan cheese for a finishing touch that’s both flavorful and visually inviting.

Make Ahead and Storage

Storing Leftovers

You can keep any leftover Butternut Squash Pasta Sauce in an airtight container in the refrigerator for up to 4 days. This saves you time for quick weekday meals without sacrificing flavor or quality.

Freezing

This sauce freezes beautifully. Portion it out into freezer-safe containers or bags and store for up to 3 months. Just thaw overnight in the fridge before reheating to enjoy that creamy magic any time you want.

Reheating

When ready to eat, gently reheat the sauce on the stove over low heat, adding a splash of water or broth to loosen it if needed. Stir often to maintain its luscious texture and prevent sticking.

FAQs

Can I use canned butternut squash instead of fresh?

While fresh butternut squash gives the best roasted flavor, you can use canned squash in a pinch. Just adjust seasoning and roasting steps accordingly since canned squash is already cooked.

Is this sauce dairy-free?

The sauce base itself is dairy-free, but the recipe calls for vegetarian Parmesan cheese for topping. You can skip or replace it with a dairy-free alternative for a vegan version.

What pasta shapes work best with Butternut Squash Pasta Sauce?

Penne is ideal because it holds the sauce well, but other tubes or ridged pastas like rigatoni or fusilli will work wonderfully too, helping scoop up that creamy goodness.

Can I add protein to this dish?

Absolutely! Grilled chicken, sautéed mushrooms, or crispy chickpeas make excellent additions that complement the flavors without overpowering the sauce’s creaminess.

How spicy is the sauce?

The red pepper flakes add just a gentle warmth, not intense heat. You can always adjust the amount to suit your taste, even omitting them if you prefer a milder sauce.
