Ingredients

  • 2 teaspoons Extra-virgin olive oil
  • 3 cups Butternut Squash, ½ inch cubes (approximately 20 ounces)
  • ½ cup Yellow onion, diced
  • 2 cloves Garlic, minced
  • 1 teaspoon Salt
  • 1 teaspoon Ground Black Pepper
  • 1 teaspoon Oregano
  • 1 cup Vegetable stock or broth (or chicken or beef broth/stock)
  • ½ cup Parmesan Cheese, grated
  • ½ cup Half and Half
  • 1 pinch Ground Nutmeg
  • 16 ounces Spaghetti pasta

Instructions

Prep-Ahead Steps

  • PREP Peel and cut the butternut squash into small ½ cubes (will cook faster). Dice the onion. Mince the garlic. Add all of these to large sheet pan.
  • ROAST Preheat oven to 400 F degrees. Drizzle olive oil, oregano, salt, and pepper over the butternut squash, then toss and rub with your hands to make sure all pieces are coated and mixed with the onion and garlic. Roast for 15 minutes or until the butternut squash are fork-tender.
  • BLEND Using a spatula, scoop up the roasted butternut squash, onions, and garlic, plus any browned bits on the pan and transfer to a blender. Add the vegetable stock/broth, the half and half, and a pinch of nutmeg to the blender and blend until smooth. Add another ¼ cup of broth if the sauce is too thick. Taste for seasonings and add salt or pepper to taste. Either store in an airtight container in the fridge or set aside until ready to add to pasta.

Pasta and Finishing Steps

  • In a large pot of boiling salted water, add a teaspoon of extra virgin olive oil and cook pasta to al dente, about 7-8 minutes. Drain well, but save a cup of the cooking pasta water for adding to the sauce if needed.
  • If your sauce needs to be reheated, add it to the pasta pot over medium heat and bring to a simmer, stirring to make sure it doesn't burn. Once warmed through, turn off the heat, add the pasta and the parmesan cheese. Mix together. If needed to thin it out, add a little of the reserved pasta water. Garnish with parmesan and enjoy!
