Butternut Squash Pasta with Creamy Sauce (Printable)

Homemade butternut squash puree blended into a velvety, flavorful sauce. A cozy, plant-based Italian-inspired pasta dish.

# What You Need:

→ Vegetables

01 - 1 medium butternut squash (about 2 lbs), peeled, seeded, and cubed
02 - 2 cloves garlic, unpeeled
03 - 1 small yellow onion, diced
04 - 1 tablespoon fresh sage leaves, chopped (or 1 teaspoon dried)
05 - 2 tablespoons fresh parsley, chopped (for garnish)

→ Pasta

06 - 12 oz dried fettuccine or tagliatelle (or fresh pasta)

→ Dairy & Liquids

07 - 2 tablespoons olive oil
08 - 1/2 cup heavy cream (or full-fat coconut milk for vegan)
09 - 1/3 cup grated Parmesan cheese (or vegan alternative)
10 - 3/4 cup vegetable broth
11 - Salt and black pepper, to taste
12 - Pinch of nutmeg (optional)

# Directions:

01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Spread the cubed butternut squash and unpeeled garlic cloves on the baking sheet. Drizzle with 1 tablespoon olive oil, sprinkle with salt and pepper, and toss to coat.
03 - Roast for 25-30 minutes, turning halfway, until the squash is tender and caramelized at the edges.
04 - Meanwhile, bring a large pot of salted water to a boil. Cook the pasta according to package instructions. Reserve 1/2 cup pasta water, then drain.
05 - In a large skillet, heat remaining 1 tablespoon olive oil over medium heat. Sauté the diced onion and sage until the onion is soft and fragrant, about 4 minutes.
06 - Squeeze the roasted garlic out of its skins. In a blender or food processor, combine roasted squash, roasted garlic, sautéed onion and sage, vegetable broth, and heavy cream. Blend until smooth and creamy.
07 - Return the squash sauce to the skillet over low heat. Stir in Parmesan cheese and a pinch of nutmeg, if using. Season with salt and pepper. If the sauce is too thick, add reserved pasta water as needed to reach desired consistency.
08 - Add cooked pasta to the sauce and toss gently to coat. Warm through for 2-3 minutes. Serve immediately, topped with chopped parsley and extra Parmesan if desired.

# Expert Advice:

01 -
  • The sauce achieves that creamy, restaurant-quality texture without loads of heavy cream, letting you feel indulgent while actually eating something nutritious.
  • Something magical happens when butternut squash caramelizes in the oven, creating deep flavors that make even pasta-purists close their eyes in appreciation at first bite.
02 -
  • Never skip salting your pasta water generously it should taste like the sea, as this is your only chance to season the pasta itself.
  • The reserved pasta water contains starch that acts as a natural thickener, so add it gradually if your sauce needs loosening instead of reaching for more cream.
03 -
  • Roast extra butternut squash whenever making this recipe and freeze it in portions for future batches, cutting your active cooking time nearly in half.
  • For the silkiest possible sauce, use an immersion blender directly in the skillet rather than transferring hot liquid to a blender and back again.
