- Garlic cloves (minced): Infuses the sauce with a warm, aromatic touch.
- Butternut squash (peeled and cubed): The star ingredient, giving the sauce its creamy texture and naturally sweet flavor.
- Vegetable broth: Enhances the overall savory taste while helping the squash soften perfectly.

- Nutmeg: Adds a whisper of warmth that rounds out the flavors beautifully.
- Black pepper: Provides a gentle kick to balance sweetness.

How to Make Creamy Butternut Squash Pasta Sauce Recipe
Step 1: Sauté the Aromatics
Begin by heating olive oil in a large skillet or saucepan over medium heat. Add the diced onion and cook it gently for about 3 to 4 minutes until it becomes soft and translucent. Then toss in the minced garlic and stir for just 30 seconds to release its fragrant aroma. This foundational step is crucial for layering the depth of flavor in your sauce.
Step 2: Cook the Butternut Squash
Add the cubed butternut squash to the pan and sauté for 5 minutes, allowing the edges to lightly caramelize and bring out natural sweetness. This step adds a lovely texture contrast that makes the final sauce incredibly smooth yet full of character.
Step 3: Simmer in Broth
Pour in the vegetable broth and bring the mixture to a boil. Once boiling, reduce the heat and let it simmer gently for 15 to 20 minutes, or until the squash is completely fork-tender. This simmer is what softens the squash enough for blending and helps infuse the sauce with a subtle savory base.
Step 4: Blend to Silky Perfection
Carefully transfer the warm butternut squash mixture into a blender. Add milk or cream along with nutmeg, black pepper, and salt. Blend everything until the sauce is incredibly smooth and creamy. This blending step is the heart of the Creamy Butternut Squash Pasta Sauce Recipe, transforming hearty squash into a velvety sauce that clings beautifully to pasta strands.
Step 5: Add Cheese and Warm Through
Return the blended sauce to the pan and stir in Parmesan cheese if you like. Warm it gently over low heat just until the cheese melts. Be careful not to boil to keep the creaminess perfect. Now your sauce is ready to elevate any pasta dish you choose!
How to Serve Creamy Butternut Squash Pasta Sauce Recipe

Garnishes
Fresh herbs like sage or thyme are absolute beauties to sprinkle on top—their earthy aroma adds brightness and a professional touch. For a bit more texture, toasted pine nuts or a sprinkle of chili flakes can provide exciting contrasts.
Side Dishes
Pair this sauce with a crisp green salad or garlic roasted vegetables to balance the richness. A crusty, warm loaf of bread is also fantastic for mopping up any leftover sauce on your plate.
Creative Ways to Present
If you’re feeling fancy, serve this sauce over stuffed pastas like ravioli or tortellini filled with cheese or mushrooms. You can even drizzle it over roasted chicken or vegetables for a delightful twist beyond pasta.

Storing Leftovers
This Creamy Butternut Squash Pasta Sauce Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days, making it perfect for quick weeknight meals or meal prepping.

FAQs
Can I use a different type of squash?
While butternut squash is perfect for its sweetness and creaminess, you can experiment with kabocha or pumpkin for a similar effect. Just adjust cooking times as needed since squash varieties vary in firmness.
Is this sauce vegan-friendly?
Absolutely! Simply swap the milk or cream for your favorite plant-based alternative and omit the Parmesan or substitute it with nutritional yeast for that cheesy flavor.
What pasta works best with this sauce?
This sauce clings wonderfully to ridged shapes like penne or rigatoni, but it’s also fabulous on stuffed pastas like ravioli. Feel free to use your favorite pasta shape—the sauce’s creamy texture is very versatile.
Can I make this sauce ahead of time?
Yes, this sauce actually develops more flavor if made a day ahead. Just store it in the refrigerator and reheat gently when you’re ready to serve.
How do I thicken the sauce if it’s too runny?
If the sauce seems a bit thin, simmer it gently over low heat to reduce and thicken. Alternatively, blend in a handful of cooked white beans or a small potato to naturally boost creaminess and body.
