Main Ingredients
- 1 medium spaghetti squash, pre-cooked (preferably in Instant Pot)
- 1 to 1 1/2 cups pasta sauce (your favorite kind)
- 1 to 1 1/2 cups shredded mozzarella cheese
Optional Add-Ins
- 1 cup pre-cooked meat (Italian sausage, ground beef, or chicken)
- 1/2 cup chopped mushrooms
- 1/4 cup sliced olives
- 1/2 cup chopped vegetables (bell peppers, onions, etc.)
- 1 teaspoon Italian seasoning
- 1/4 cup grated Parmesan cheese
Instructions
- Preheat oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole.
- Prepare the baking dish: Place the pre-cooked spaghetti squash into a 9×9 inch baking dish. If you have more squash, use a larger dish to accommodate the quantity.
- Combine ingredients: Stir in the pasta sauce into the spaghetti squash thoroughly. Add your desired optional add-ins such as pre-cooked meats, mushrooms, olives, vegetables, and Italian seasoning to enhance the flavor and texture.
- Add cheeses: Sprinkle the shredded mozzarella cheese evenly over the mixture. Optionally, you can also add grated Parmesan cheese on top for extra flavor.
- Bake the casserole: Place the baking dish in the oven and bake for about 30 minutes, or until the cheese is melted, bubbly, and the casserole is heated through completely.
- Broil for crispy cheese (optional): For a golden-brown, crispy cheese topping, switch your oven to the broil setting and broil the casserole for 3 to 5 minutes. Keep a close eye on it to prevent burning.
- Serve: Remove the casserole from the oven, let it cool slightly, then serve warm as a tasty and wholesome meal.
Notes
- You can cook the spaghetti squash ahead of time in an Instant Pot, oven, or microwave before assembling the casserole.
- Feel free to customize the add-ins based on your preference or what you have on hand; Italian seasoning adds a great flavor dimension.
- Broiling the cheese at the end is optional but recommended for a crispy, golden topping.
- This casserole keeps well in the refrigerator for 3-4 days and reheats nicely.
- For a gluten-free version, confirm your pasta sauce does not contain gluten-containing additives.
