  • 1 medium spaghetti squash
  • 1 small yellow onion chopped
  • 1 cup mozzarella cheese shredded
  • 1 cup Ragu Homestyle Thick & Hearty Roasted Garlic Pasta Sauce
  • 1 cup mushrooms chopped
  • 1 cup water
  • 1/2 cup ricotta cheese part skim
  • 1/4 cup parmesan cheese grated
  • 1 tsp salt
  • 1 tsp pepper
  • 1 tsp dried oregano
  • 1 tsp dried thyme
  1. Preheat oven to 400°F. Place about 1 cup of water on baking sheet, or enough to just cover the bottom. 

  2. Cut spaghetti squash in half and scoop out seeds. Place squash open-side-down on baking sheet. Bake for about 30 minutes, or until a fork goes through the squash easily. Remove from oven and allow to cool. 

  3. Lower oven temperature to 350°F.

  4. Use a fork to remove insides of squash into a medium sized bowl. Stir squash together with ricotta cheese, salt, pepper, oregano, thyme, onion, mushrooms, Ragu sauce, and half of the mozzarella. 

  5. Place mixture evenly inside of each spaghetti squash shell. Top with remaining mozzarella and parmesan cheese.

  6. Bake for additional 20-30 minutes, or until tops are golden brown and cheese is melted.
