Ingredients

This recipe uses simple, wholesome ingredients to create a rich and flavorful dish.

For the Roasted Butternut Squash:

  • 1 medium butternut squash (about 2 lbs), peeled, seeded, and cut into 1-inch cubes
  • 1 tablespoon olive oil
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

For the Pasta and Sauce:

  • 12 ounces pasta (e.g., penne, rigatoni, fusilli)
  • 1 tablespoon olive oil
  • 1 medium yellow onion, chopped
  • 4 cloves garlic, minced
  • 8-10 fresh sage leaves, roughly chopped, plus more for garnish
  • 2 cups vegetable broth
  • 1 cup unsweetened plant-based milk (almond, cashew, or oat work well)
  • ¼ cup nutritional yeast
  • 1 tablespoon lemon juice
  • Pinch of ground nutmeg
  • Salt and black pepper to taste

Step-by-Step Instructions

Follow these clear steps to create your delicious Creamy Roasted Butternut Squash and Sage Pasta.

  1. Roast the Butternut Squash: Preheat your oven to 400°F (200°C). On a large baking sheet, toss the cubed butternut squash with 1 tablespoon olive oil, ½ teaspoon salt, and ¼ teaspoon black pepper. Spread the squash in a single layer. Roast for 25-30 minutes, or until the squash is tender and lightly caramelized.
  2. Cook the Pasta: While the squash roasts, bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package directions until al dente. Before draining, reserve about 1 cup of the starchy pasta water. Drain the pasta and set aside.
  3. Sauté Aromatics: In a large skillet or Dutch oven, heat the remaining 1 tablespoon olive oil over medium heat. Add the chopped yellow onion and cook for 5-7 minutes, until softened and translucent. Add the minced garlic and chopped fresh sage leaves, cooking for another 1-2 minutes until fragrant, being careful not to burn the garlic.
  4. Prepare the Creamy Sauce: Once the butternut squash is roasted, carefully transfer it to a high-speed blender. Add the sautéed onion, garlic, and sage mixture from the skillet to the blender. Pour in the vegetable broth, plant-based milk, nutritional yeast, lemon juice, and a pinch of ground nutmeg. Blend until completely smooth and creamy. If the sauce is too thick, add a splash of the reserved pasta water until it reaches your desired consistency. Taste and adjust seasoning with salt and pepper as needed.
  5. Combine and Serve: Pour the creamy butternut squash sauce into the skillet or Dutch oven (the one used for aromatics). Add the cooked pasta and toss gently to coat evenly with the sauce. If the sauce seems too thick, add a little more reserved pasta water until it’s perfectly saucy.
  6. Garnish and Enjoy: Serve immediately, garnished with extra fresh sage leaves and a crack of black pepper, if desired.

Pro Tips for Success

Elevate your pasta dish with these expert tips:

  • Even Squash Cubes: Cut your butternut squash into uniform 1-inch cubes. This ensures that all pieces roast evenly and become tender at the same time, contributing to a consistently smooth sauce.
  • Don’t Overcrowd the Pan: When roasting the squash, ensure it’s spread in a single layer on the baking sheet. If the pan is overcrowded, the squash will steam instead of roast, preventing it from caramelizing and developing its full sweet flavor. Use two baking sheets if necessary.
  • Bloom the Sage: Sautéing the fresh sage leaves briefly with the onion and garlic helps to “bloom” their flavor, releasing their essential oils and intensifying their aromatic qualities into the sauce base.
  • Reserve Pasta Water: Always reserve some starchy pasta water before draining. This liquid is gold for adjusting the sauce consistency, helping it to cling beautifully to the pasta and emulsify for an extra creamy finish.

Variations & Substitutions

Customize this creamy pasta to suit your preferences and dietary needs.

  • Gluten-Free Option: Simply use your favorite gluten-free pasta variety. Most brands offer excellent texture and flavor that will work perfectly in this dish.
  • Higher Protein Option: For an added protein boost, stir in a can of drained and rinsed cannellini beans or chickpeas along with the pasta. You could also crumble in some plant-based sausage during the sautéing step.
  • Add Some Greens: Wilt a few handfuls of fresh spinach or kale into the sauce just before serving. The residual heat will cook them down, adding nutrients and a pop of color.
  • Spicy Kick: If you enjoy a bit of heat, add a pinch or two of red pepper flakes to the skillet when sautéing the garlic and sage.
  • Herb Swaps: While sage is classic, fresh thyme or rosemary can also be used. Add them with the garlic and cook until fragrant.
  • Nut-Free Creaminess: If you need a nut-free option, ensure your plant-based milk is nut-free (like oat milk) and consider adding a tablespoon of sunflower seed butter to the blender for extra richness, if desired.

Serving Suggestions

This Creamy Roasted Butternut Squash and Sage Pasta is a hearty and satisfying meal on its own, perfect for a cozy autumn or winter evening. To complete the meal, consider serving it alongside a crisp green salad with a light vinaigrette to cut through the richness. A slice of crusty bread or garlic bread is also wonderful for soaking up any extra sauce. It’s an excellent choice for a comforting weeknight dinner or a lovely dish to share with friends and family.

Storage & Reheating

Proper storage ensures you can enjoy your leftovers just as much as the fresh meal.

  • Refrigerator: Store any leftover pasta in an airtight container in the refrigerator for up to 3-4 days.
  • Freezer: While the sauce itself freezes well, pasta can become a bit mushy when frozen and thawed. If you plan to freeze, it’s best to freeze the sauce separately in an airtight container for up to 2-3 months. Thaw overnight in the refrigerator, then gently reheat and toss with freshly cooked pasta.
  • Reheating: To reheat, gently warm the pasta in a skillet over medium-low heat, adding a splash of vegetable broth or plant-based milk to help loosen the sauce and restore its creamy texture. You can also microwave individual portions, stirring halfway through.

Frequently Asked Questions

Can I make the butternut squash sauce ahead of time?

Absolutely! The creamy butternut squash sauce can be prepared up to 2-3 days in advance and stored in an airtight container in the refrigerator. When ready to serve, gently reheat the sauce on the stovetop, adding a splash of broth or plant milk if needed, then toss with freshly cooked pasta.

What if I don’t have fresh sage? Can I use dried sage?

Fresh sage offers the best flavor, but you can substitute dried sage. Use about 1 teaspoon of dried sage for every tablespoon of fresh sage. Add the dried sage to the skillet with the onion and garlic to allow its flavors to bloom.

My sauce seems too thick/thin. How can I fix it?

If your sauce is too thick, gradually add more reserved pasta water or vegetable broth, a tablespoon at a time, until it reaches your desired consistency. If it’s too thin, you can simmer it gently on the stovetop for a few minutes to allow it to reduce and thicken slightly, or add another tablespoon of nutritional yeast.

Final Thoughts

This Creamy Roasted Butternut Squash and Sage Pasta is more than just a meal; it’s an experience of warmth, comfort, and incredible flavor. The velvety sauce, the tender pasta, and the aromatic sage combine to create a dish that truly satisfies.
