Description

Make a rich, creamy pasta sauce using roasted butternut squash, garlic, and sage. This recipe is easy to prepare and works well for weeknight dinners.


Ingredients

Scale
  • 1 medium butternut squash (about 3 lbs)
  • 2 tablespoons olive oil, divided
  • 1 small yellow onion, chopped
  • 4 cloves garlic, minced
  • 1 cup vegetable broth
  • 1/2 cup full-fat coconut milk (canned, not refrigerated beverage)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon nutmeg
  • 1 tablespoon fresh sage leaves, chopped
  • 1 pound pasta of your choice


Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Cut the butternut squash in half lengthwise and scoop out the seeds. Rub the cut sides with 1 tablespoon of olive oil, salt, and pepper. Place cut-side down on a baking sheet.
  2. Roast the squash for 35 to 45 minutes, or until it is very tender when pierced with a fork. Let it cool slightly, then scoop the flesh out of the skin into a bowl. You should have about 3 cups of cooked squash.
  3. While the squash roasts, heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the chopped onion and cook until soft, about 5 minutes.
  4. Add the minced garlic and chopped sage to the skillet. Cook for 1 minute until fragrant.
  5. Transfer the roasted squash, onion mixture, vegetable broth, coconut milk, salt, pepper, and nutmeg to a high-speed blender. Blend until the sauce is completely smooth and creamy. If the sauce is too thick, add a splash more broth or water until you reach your desired consistency.
  6. Return the sauce to the skillet and heat gently over low heat. Taste and adjust seasoning if needed.
  7. Cook your pasta according to package directions. Drain the pasta, reserving about 1/2 cup of the starchy cooking water.
  8. Toss the cooked pasta directly into the skillet with the sauce. Add a splash of the reserved pasta water if the sauce seems too thick. Serve immediately.

Notes

  • For a dairy version, substitute the coconut milk with 1/2 cup heavy cream or half-and-half.
  • Roasting the squash provides the best depth of flavor for this sauce.
  • This sauce freezes well for up to 3 months; cool completely before storing in an airtight container.
