Ingredients
  

  • 1 medium Spaghetti Squash about 3 pounds
  • 1 Yellow Onion chopped
  • 1 Green Pepper chopped
  • 4 cloves Garlic minced
  • 1 24 ounce jar Marinara Sauce
  • 8 oz Mozarella Cheese shredded (2 cups)
  • 4 teaspoons Olive Oil divided
  • 1 teaspoon Oregano
  • ¼ teaspoon Black Pepper

Instructions
 

  • Preheat oven to 400 degrees.
  • Cut the squash in half lengthwise and scoop out the seeds with a spoon. Brush 2 teaspoons of olive oil on the inside of the squash.
  • Place the squash cut side down on a baking sheet and roast for 40 minutes or until the skin can easily be pierced with a fork.
  • While the squash is roasting, saute the onion and green pepper with 2 teaspoons of olive oil over medium-high heat for 3-4 minutes until tender.
  • Add the garlic and cook for an additional minute.
  • Add in the marinara sauce, oregano, and black pepper. Simmer over low heat until ready for use.
  • Remove the squash from the oven, turn them over, and let cool 10 minutes or until able to handle.
  • Use a fork to scrape the strands of squash from the skin. Place the spaghetti squash in a large mixing bowl.
  • Combine the spaghetti squash and marinara sauce. Stir and transfer to a 9x13 baking dish. Sprinkle mozzarella cheese over top.
  • Bake at 350 degrees for 20 minutes or until cheese is melted. I then like to broil for 2 minutes to brown the top a bit.
  • Remove from the oven and garnish with fresh basil, and/or crushed red pepper. Enjoy!
