A delightful twist on the classic spaghetti bake, featuring a creamy cheese blend and flavorful meat sauce.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
Cook the spaghetti in a large pot of salted boiling water until al dente, then drain.
Don't overcook the pasta as it will continue to cook in the oven.
In a large bowl, whisk together the egg, milk, salt, and pepper.
Ensure the egg is fully beaten for a smooth mixture.
Add the cooked spaghetti to the egg mixture and toss to coat evenly.
Toss gently to avoid breaking the spaghetti.
Transfer the spaghetti mixture to a greased baking dish.
Spread the mixture evenly for uniform baking.
In a skillet, cook the ground beef, sausage, and onion over medium heat until browned and cooked through.
Break up the meat into small pieces for even cooking.
Stir the tomato sauce into the meat mixture and let it simmer for 5 minutes.
Simmering enhances the flavors of the sauce.
Pour the meat sauce over the spaghetti in the baking dish.
Spread the sauce evenly for consistent flavor.
Sprinkle the shredded mozzarella cheese over the top.
Cover the entire surface for a cheesy crust.
Bake uncovered for 20 minutes, then let it rest for 10 minutes before serving.
Resting allows the casserole to set for easier serving.
