Ground Beef Casserole

Step 3: Sauté Vegetables

Add the chopped onion, garlic, and bell pepper to the skillet with the beef. Cook for 4–5 minutes until the vegetables are softened and fragrant.

Tip: Stir frequently to prevent garlic from burning—it turns bitter if overcooked.

Step 4: Add Seasonings and Tomato

Mix in salt, pepper, paprika, Italian seasoning, and red pepper flakes. Stir to coat the beef and vegetables evenly.

Pour in the diced tomatoes and tomato sauce, then add frozen corn if using. Simmer for 8–10 minutes, allowing the sauce to thicken slightly. Taste and adjust seasoning if needed.

Step 5: Combine with Pasta

In a large bowl, combine the cooked pasta with the beef and vegetable mixture. Stir well so that every piece of pasta is coated in the flavorful sauce.

Step 6: Layer the Casserole

Pour half of the mixture into your prepared baking dish. Sprinkle 1 cup of shredded cheddar cheese evenly over the first layer. Add the remaining beef-pasta mixture, then top with the remaining 1 cup of cheese.

For extra crunch, sprinkle bread crumbs over the top.

Step 7: Bake

Cover the dish loosely with aluminum foil and bake for 20 minutes. Remove the foil and bake for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden.

Step 8: Serve

Let the casserole rest for 5–10 minutes before serving. This allows the layers to set and makes it easier to slice. Serve with a fresh green salad or garlic bread for a complete meal.

Tips for a Perfect Ground Beef Casserole:

1. Customize vegetables – Add mushrooms, zucchini, or spinach for extra nutrition.
2. Cheese variations – Try mozzarella, pepper jack, or a blend for different flavors.
3. Make ahead – Prepare the casserole a day in advance and bake just before serving.
4. Freeze for later – Assemble without baking, freeze in an airtight container, and bake directly from frozen at 375°F (190°C) for 45–55 minutes.
