Spaghetti Squash Pizza Casserole is an easy vegetarian meal that is healthy and delicious! It is low calorie, low carb, and naturally gluten-free.
Spaghetti Squash is a great substitution for pasta as it is low in calories (only 40 per cup), low in carbohydrates (10 grams per cup) and packed full of nutrients such as B vitamins, vitamin C, beta-carotene, and fiber.
Ingredients you will need to make this recipe
Spaghetti Squash - One medium spaghetti squash (about 3 pounds) is used for this recipe.
Other Veggies - a green pepper, an onion, and four cloves of garlic add some amazing flavor!
Marinara Sauce - a 24 ounce jar of your favorite sauce
Mozzarella Cheese - 8 ounces which is equivalent to 2 cups
Olive Oil - I prefer extra virgin
Spices - oregano and black pepper
How to Make
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 on 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 the spaghetti squash pizza casserole from the oven and garnish with fresh basil, and/or crushed red pepper.
Cheesy, saucy, and oh so good!
