If you’re feeling fancy, you can also add some fresh sage leaves for garnish—they complement the butternut squash beautifully.

Equipment Needed

Here’s what you’ll need to make this creamy butternut squash pasta sauce:

• Cutting board and knife: For peeling and cubing the squash. A sharp knife makes this much easier!
• Baking sheet: For roasting the squash. Line it with parchment paper for easy cleanup.
• Blender or food processor: To blend the roasted squash into a smooth and creamy sauce.
• Large skillet: For sautéing the aromatics and combining the sauce.
• Wooden spoon: Perfect for stirring the sauce without scratching your skillet.

If you don’t have a blender, you can use an immersion blender directly in the skillet—it’s a great option for easy cleanup!

Preparation Method

1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare the butternut squash by peeling, seeding, and cutting it into 1-inch cubes. Toss the cubes with 2 tablespoons of olive oil, a pinch of salt, and a dash of pepper. Spread them out on the baking sheet in a single layer.
3. Roast the squash for 20-25 minutes, or until it’s tender and starting to caramelize. You’ll know it’s ready when you can easily pierce the pieces with a fork.
4. While the squash roasts, heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and sauté for 3-4 minutes until softened and translucent. Add the minced garlic and cook for an additional minute, stirring frequently to prevent burning.
5. Once the squash is roasted, transfer it to a blender or food processor along with the sautéed onion and garlic. Add 1 cup of vegetable stock, ½ cup of milk, and a pinch of nutmeg. Blend until the sauce is creamy and smooth. If the sauce is too thick, add more vegetable stock, 1 tablespoon at a time, until you reach your desired consistency.
6. Pour the blended sauce back into the skillet and heat over low, stirring occasionally. Add ½ cup of grated parmesan cheese and stir until melted and fully incorporated. Taste and adjust seasoning with more salt and pepper if needed.
7. Cook your favorite pasta according to package instructions. Reserve ½ cup of pasta water before draining.
8. Toss the cooked pasta with the butternut squash sauce, adding the reserved pasta water as needed to thin the sauce and help it coat the pasta evenly.
9. Garnish with more parmesan cheese and fresh sage leaves, if desired, and serve immediately. Enjoy!

Cooking Tips & Techniques

To make sure your creamy butternut squash pasta sauce turns out perfectly, here are a few tips I’ve learned along the way:

• Roast the squash: Roasting brings out its natural sweetness and adds depth of flavor. Don’t skip this step!
• Don’t overcook the garlic: Garlic can become bitter if it burns, so keep an eye on it while sautéing.
• Use a high-powered blender: For the creamiest texture, a good blender or food processor makes a big difference.
• Adjust consistency: If the sauce seems too thick, add small amounts of vegetable stock or pasta water until it’s just right.
• Season as you go: Taste the sauce as you cook and adjust the seasoning to your liking. A little extra salt or nutmeg can make all the difference!

And remember, cooking is all about experimenting and having fun. Don’t be afraid to make it your own!

Variations & Adaptations

One of the best things about this creamy butternut squash pasta sauce is how versatile it is. Here are a few ideas to mix it up:

• Make it vegan: Swap the milk for unsweetened almond or coconut milk and use nutritional yeast instead of parmesan cheese.
• Add protein: Stir in shredded rotisserie chicken, crumbled bacon, or sautéed sausage. It turns this into a hearty main course.
• Seasonal twist: In the fall, add a sprinkle of cinnamon or a drizzle of maple syrup for extra warmth. In the summer, toss in some fresh basil or thyme for a lighter flavor.
• Gluten-free option: Serve the sauce with gluten-free pasta or spiralized zucchini noodles for a lower-carb alternative.

My personal favorite variation? I love adding a splash of white wine to the sauce while it’s heating in the skillet—just enough to give it a little extra zing!

Serving & Storage Suggestions

This creamy butternut squash pasta sauce is best served warm, tossed with your favorite pasta for a comforting meal. Sprinkle with extra parmesan cheese and garnish with sage leaves for a pretty presentation.

Pair it with a simple green salad or garlic bread for a complete dinner. If you’re feeling fancy, a glass of white wine like Sauvignon Blanc complements the flavors beautifully.

Got leftovers? Store the sauce in an airtight container in the refrigerator for up to 3 days. To reheat, warm it gently on the stove over low heat, adding a splash of vegetable stock or milk to loosen it up. You can also freeze the sauce for up to 3 months—just thaw it overnight in the fridge before reheating.
