Instructions

Preheat the Oven: Set your oven to 350°F (175°C) to prepare it for baking the casserole.
Prepare the Baking Dish: Place the pre-cooked spaghetti squash evenly in a 9×9 inch baking dish. If you have more squash, use a larger dish to fit it comfortably.
Add Sauce and Toppings: Stir the pasta sauce into the squash until well combined. Mix in any optional add-ins you like, such as pre-cooked meat, mushrooms, olives, veggies, and sprinkle the Italian seasoning evenly.
Top with Cheese: Generously sprinkle shredded mozzarella and parmesan cheese over the squash and sauce mixture, ensuring even coverage.
Bake the Casserole: Place the dish in the preheated oven and bake for about 30 minutes, or until the cheese is melted, bubbly, and the casserole is heated through.
Optional Broil: For a crispy, browned cheese topping, turn your oven to broil for 3-5 minutes after baking. Watch carefully to prevent burning.
Serve: Remove from oven and let it cool slightly before serving. Enjoy your hearty and healthy spaghetti squash pizza casserole!
