Ingredients You’ll Need
What I love most about this recipe is how simple yet thoughtfully chosen the ingredients are. Each one plays an essential role in building the flavor, texture, and beautiful color of the sauce, turning humble components into something spectacular.
- Butternut squash, peeled + cubed: The star ingredient, roasted to sweet perfection for a creamy base.
- Shallot (or small red onion): Adds subtle sweetness and aromatic depth.
- Garlic cloves: Bring a warm, pungent aroma that complements the squash beautifully.
- Olive oil: Helps roast the veggies and adds smooth richness.
- Dried thyme (or fresh): Offers herbal notes that brighten the sauce’s flavor.
- Salt + pepper, to taste: Essential for seasoning and balancing the sauce.
- Fresh parsley: Adds vibrant color and fresh, grassy notes.
- Parmigiano-reggiano cheese: Gives a savory, nutty flavor and creamy texture.
- Reserved pasta water (or veggie broth): Provides the perfect liquid to blend everything smoothly while adding a touch of starchiness to bind the sauce.
How to Make Creamy Butternut Squash Pasta Sauce Recipe
Step 1: Prep Your Ingredients
Start by preheating your oven to 400°F. Take your butternut squash and peel it carefully before cutting it in half and scooping out the seeds. Then chop the squash into small chunks about three-quarters of an inch each for even roasting. Peel and slice your shallot or red onion, and peel the garlic cloves so everything is ready to toss together.
Step 2: Toss and Season
Place your chopped butternut squash, shallot slices, and whole garlic cloves into a big baking dish. Drizzle them with olive oil, sprinkle on the thyme, and season generously with salt and pepper. Toss everything gently so the olive oil and seasonings coat each piece well, setting the stage for roasting.
Step 3: Roast the Vegetables
Roast the veggies in the oven for about 30 to 35 minutes, tossing halfway through to ensure even cooking. You’ll know they’re done when the squash is tender enough to pierce with a fork easily and the edges have developed a lovely golden color and caramelized flavor—a game changer in this sauce.
Step 4: Cook Pasta (Optional)
If you plan to serve this sauce with pasta, now’s the time to cook it in salted boiling water. Make enough to serve 4 to 6 people, and don’t forget to scoop out up to two cups of that starchy pasta water before draining! This liquid is a key player when blending your sauce, helping create that silky consistency. If you’re skipping the pasta, feel free to use vegetable broth instead for that perfect texture.
Step 5: Blend the Sauce
Transfer your roasted squash, onions, garlic, and all those delicious pan juices right into a high-speed blender. Add fresh parsley, a generous cup of freshly grated parmigiano-reggiano cheese, and 1.5 cups of your reserved pasta water or broth. Blend everything until it reaches a smooth, creamy texture—you might need to use your blender’s tamper to nudge the ingredients down and get everything perfectly pureed.
Step 6: Adjust Seasonings and Texture
This is where you get to make the sauce your own. Taste it and add more salt, pepper, or thyme if you want to brighten the flavors. If you prefer a thinner sauce, pour in additional broth or pasta water a splash at a time until you’re happy with the consistency.
Step 7: Serve or Store
Once your sauce is dreamy and smooth, toss it with warm, freshly cooked pasta or hold onto it for another day—this sauce keeps beautifully in the fridge for later use. It’s a perfect make-ahead option that always impresses.

Garnishes
To elevate this sauce even more, I love sprinkling freshly chopped parsley or basil on top for a burst of color and fresh herbal brightness. A little extra grated parmigiano-reggiano never hurts either—plus, a few cracked black peppercorns add just the right bit of punch.
Side Dishes
This pasta sauce pairs wonderfully with simple, crisp side salads dressed lightly with lemon vinaigrette or roasted seasonal vegetables that complement the nutty sweetness of the squash. A crusty slice of garlic bread is also the perfect vehicle to soak up every last drop.
Creative Ways to Present
Don’t hesitate to get creative and serve this sauce over ravioli, gnocchi, or even spiralized veggies for a low-carb twist. You can also layer it in a baked pasta casserole topped with mozzarella for a rich and gooey crowd-pleaser. It’s incredibly versatile and always a showstopper!
Make Ahead and Storage
Storing Leftovers
If you have any Creamy Butternut Squash Pasta Sauce Recipe leftover, simply store it in an airtight container in the refrigerator. It will keep well for up to 4 days and still retain its luscious quality.
Freezing
This sauce freezes beautifully! Portion it out into freezer-safe containers or bags, leaving a little room for expansion. Freeze for up to 3 months, so you can enjoy this comforting dish anytime you want with minimal effort.
Reheating
When reheating, gently warm the sauce over low heat on the stove or in the microwave with frequent stirring. You might want to add a splash of water or broth to regain that perfect creamy texture since sauces can thicken in the fridge and freezer.
FAQs
Can I make this sauce vegan?
Absolutely! To make this Creamy Butternut Squash Pasta Sauce Recipe vegan, simply substitute the parmigiano-reggiano with a plant-based cheese or nutritional yeast and use vegetable broth instead of pasta water.
What pasta goes best with this sauce?
The sauce is incredibly versatile and pairs well with many pasta types, but I especially love it with fettuccine, penne, or even gnocchi for their ability to hold onto the creamy sauce beautifully.
Can I use fresh herbs instead of dried thyme?
Yes! Fresh thyme works wonderfully and adds a brighter, slightly more floral note. Use about twice the amount of fresh thyme as dried since fresh herbs are less concentrated.
Is it necessary to roast the butternut squash?
Roasting enhances the natural sweetness and depth of flavor in the squash, which is key to this sauce’s richness. While you can boil or steam the squash as a shortcut, roasting truly takes the sauce to the next level!
Can this sauce be used for other dishes?
Definitely! This sauce is fantastic not only on pasta but as a base for creamy soups, a drizzle over grilled chicken or roasted veggies, or a dip with crusty bread. Versatile comfort food at its best.

Ingredients
Butternut Squash Sauce
- 4 cups butternut squash, peeled and cubed
- 1 shallot (or small red onion)
- 3 large cloves garlic
- 2 Tbsp olive oil
- 1 Tbsp dried thyme (or 2 Tbsp fresh thyme)
- Salt and pepper, to taste
- 1/4 cup fresh parsley
- 1 cup freshly grated Parmigiano-Reggiano cheese
- 1.5 cups reserved pasta water (or vegetable broth if not cooking with pasta)
Instructions
- Prep: Preheat your oven to 400°F (205°C). Peel the butternut squash, cut it in half, and remove the seeds. Then cut the squash into approximately 3/4-inch pieces. Peel and slice the shallot or onion, and peel the garlic cloves.
- Toss: Place the cubed squash, shallot, and garlic cloves in a large baking dish. Toss them with olive oil, dried thyme, salt, and pepper until evenly coated.
- Roast: Roast the squash and seasonings in the oven for 30 to 35 minutes, stirring or tossing halfway through. The squash is done when it’s easily pierced with a fork and tender.
- Cook Pasta (optional): If serving with pasta, cook enough pasta for 4 to 6 servings in a large pot of salted boiling water. Reserve about 1.5 cups of the pasta cooking water before draining. If not using pasta, simply use vegetable broth for the sauce liquid.
- Blend: Transfer the roasted squash, onion, garlic, and seasonings to a high-speed blender. Add fresh parsley, Parmigiano-Reggiano cheese, and 1.5 cups of the reserved pasta water or broth. Blend until smooth, using the blender tamper to help incorporate all ingredients evenly.

Notes
- For a vegan version, omit the Parmesan and substitute nutritional yeast or vegan cheese.
- Fresh thyme adds a more vibrant flavor, but dried thyme works well and is more convenient.
- Make sure to reserve pasta water as its starchiness helps the sauce cling to pasta perfectly.
- This sauce can be reheated gently on the stovetop or microwave; add a splash of broth or water if it thickens too much.
- You can roast the squash a day ahead to speed up meal preparation.
