Scale
Main Ingredients
- 8 cups leftover spaghetti with sauce
- 4 eggs
- ¼ cup milk
- ½ cup grated Parmesan cheese
- 2 cups shredded sharp cheddar cheese or mozzarella cheese, divided
Instructions
- Preheat Oven. Preheat the oven to 350 degrees Fahrenheit to prepare for baking the casserole.
- Prepare Baking Dish. Spray a 9×13 inch casserole dish with nonstick cooking spray to prevent sticking and ensure easy cleanup.
- Mix Eggs and Milk. In a large mixing bowl, whisk together the 4 eggs and ¼ cup milk until the mixture is smooth and thoroughly combined.
- Add Parmesan Cheese. Stir in ½ cup of grated Parmesan cheese, mixing well to incorporate the cheese into the egg mixture.
- Combine Spaghetti. Add the 8 cups of leftover spaghetti with sauce to the bowl and toss with the egg and cheese mixture until the spaghetti is evenly coated.
- Add Cheddar Cheese. Mix in 1 cup of the shredded sharp cheddar or mozzarella cheese until well combined with the spaghetti mixture.
- Transfer to Dish. Pour the spaghetti mixture into the prepared baking dish, spreading it evenly.
- Initial Bake. Cover the casserole dish and bake for 30 to 40 minutes until the dish is heated through and set.
- Add Topping Cheese. Remove the cover and sprinkle the remaining 1 cup of shredded cheddar or mozzarella cheese evenly over the top of the casserole.
- Final Bake. Return the uncovered casserole to the oven and bake for an additional 5 to 10 minutes until the cheese is fully melted and golden.
Notes
- Use any leftover spaghetti with sauce; meat or vegetarian versions both work well.
- Feel free to substitute milk with a dairy-free alternative if desired.
- Cheddar or mozzarella cheese can be mixed or substituted with your favorite melting cheese.
- To enhance flavor, add sautéed onions, garlic, or herbs like basil or oregano to the mixture.
- Ensure spaghetti is well coated with egg mixture to help bind the bake together.
- For a crispier top, broil the casserole for 1-2 minutes after the final bake, watching carefully to avoid burning.
