A smooth vegan pasta sauce made from roasted squash, tomatoes, and onion for an easy, comforting fall meal.

Ingredients

Scale
  • 16 oz bag frozen diced butternut squash
  • 1.5 cups fresh chopped tomatoes
  • 1/2 yellow onion, sliced
  • 2 tbsp olive oil
  • 1 tsp salt
  • 1/4 tsp black pepper
  • 1/2 tsp dried thyme
  • 1 lb pasta
  • 1/3 cup pasta water, reserved from the cooked pasta

Instructions

  1. Preheat the oven to 450°F and line a baking sheet with parchment paper for easy cleanup.
  2. Spread the frozen butternut squash, chopped tomatoes, and sliced onion across the prepared sheet pan. Try to keep the vegetables in a fairly even layer so they roast evenly.
  3. Drizzle the olive oil over the vegetables, then season with the salt, black pepper, and dried thyme.
  4. Toss everything together on the pan until the vegetables look evenly coated with the oil and seasonings.
  5. Place the pan in the oven and roast for about 20 minutes, or until the squash softens and the vegetables begin to caramelize slightly.
  6. While the vegetables roast, cook the pasta in a large pot according to the package directions.
  7. Just before draining the pasta, scoop out 1/3 cup of the pasta water and pour it into a blender. Drain the pasta and set it aside.
  8. When the vegetables are done roasting, transfer the hot mixture directly into the blender with the reserved pasta water.
  9. Blend until the sauce becomes completely smooth and creamy. Stop and scrape down the sides if needed so everything mixes evenly.
  10. Pour the finished sauce over the cooked pasta and toss well until the noodles are fully coated.
  11. Serve immediately with parmesan cheese, or use a plant-based parmesan alternative to keep it vegan.
