  • 1 lb package of pasta of your choice
  • 1/3 cup pasta water
  • 2 tbsp. olive oil
  • 2 tbsp. butter sub for more olive oil for a vegan version
  • 3 gloves of garlic minced
  • 1 shallot minced
  • 1 tbsp. fresh sage chopped
  • 1 cup butternut squash cubed
  • 1 cup low-sodium vegetable broth
  • 2/3 cup pumpkin puree
  • 1 tsp. tomato paste
  • 1/2 of a 15 oz. can of fire roasted tomatoes
  • 1/2 tsp. salt
  • 1/4 tsp. pepper
  • 1/4 tsp. red pepper flakes
  • 1/4 tsp. allspice
  • 1/8 tsp. pumpkin pie spice or cinnamon
  • 1/3 cup oat milk
  • 1/3 cup grated parmesan cheese + extra for sprinkling on top
  • 2 cups fresh spinach


  • Cook pasta according to package directions. When draining reserve 1/3 cup of the water to use later in this recipe.
  • Mince the garlic, and shallot. Add olive oil, butter (if using) and garlic and shallot to a sauté pan. Stir and saute until fragrant. Add the fresh sage and butternut squash. If using frozen butternut squash sauté until it is no longer frozen. 
  • Next, add the vegetable broth, pumpkin puree, tomato paste and fire roasted tomatoes. Stir and turn the heat down to low to let simmer.
  • Add salt, pepper, red pepper flakes, allspice and pumpkin spice. Stir together, cover and let simmer for 5-6 minutes. Add pasta water and let simmer for an additional 5 minutes. 
  • Remove from heat and carefully transfer the sauce into a blender. Add oat milk and parmesan cheese.
  • Blend on high until you see that the sauce is well combined and not chunky.
  • Pour sauce back into your pan, add pasta and fold in spinach over low heat. 
  • Remove from heat, portion and serve. I like it with extra grated parmesan cheese on top and fresh spinach! 


This sauce can definitely be frozen for future use.
