Ground Beef Casserole

Step 3: Create the Sauce

Pour the tomato sauce and diced tomatoes into the skillet with the beef mixture. Stir everything together thoroughly.

Reduce the heat to medium-low and allow the sauce to simmer for 10 minutes. This step helps blend the flavors and creates a rich, savory base for the casserole.

Taste the mixture and adjust the seasoning if needed.

Step 4: Combine the Ingredients

Preheat the oven to 375°F (190°C).

In a large mixing bowl, combine the cooked pasta with the beef and tomato sauce mixture. Stir gently until every piece of pasta is coated with sauce.

Add half of the cheddar cheese and mix it into the casserole. This creates pockets of melted cheese throughout the dish.

Step 5: Assemble the Casserole

Lightly grease a 9×13-inch baking dish.

Transfer the pasta and beef mixture into the prepared dish and spread it evenly. Sprinkle the remaining cheddar cheese and all of the mozzarella cheese over the top.

The generous cheese layer will form a golden, bubbly crust during baking.

Step 6: Bake Until Golden

Place the casserole in the preheated oven and bake for 20 to 25 minutes.

The casserole is ready when the cheese has melted completely and begins to turn lightly golden around the edges. If you prefer a darker cheese topping, switch the oven to broil for 2 to 3 minutes at the end of the cooking time.

Watch carefully to prevent burning.

Step 7: Rest and Serve

Remove the casserole from the oven and allow it to rest for 5 to 10 minutes before serving. This resting period helps the casserole set and makes it easier to portion.

Garnish with freshly chopped parsley if desired.

Serve with a simple green salad, steamed vegetables, or warm garlic bread for a complete meal.
