Ingredients

For the Beef and Vegetable Base

  • 1 1/2 pounds ground beef
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 bell pepper, diced (any color)
  • 1 cup corn kernels (fresh, frozen, or canned and drained)
  • 1 can (14–15 ounces) diced tomatoes, drained
  • 1 can (8 ounces) tomato sauce
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon paprika
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon chili powder (optional for mild heat)

For the Creamy Layer (Optional but Recommended)

  • 1 cup sour cream or softened cream cheese
  • 1/2 cup shredded mozzarella

For the Cheese Topping

  • 1 1/2 cups shredded mozzarella
  • 1 cup shredded cheddar

Equipment Needed

  • Large skillet
  • Mixing spoon or spatula
  • 9×13-inch baking dish
  • Oven preheated to 375°F
  • Knife and cutting board

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of oil.

Step 2: Cook the Ground Beef

Place a large skillet over medium heat. Add the ground beef and cook until browned, breaking it apart with a spatula as it cooks. This usually takes 6 to 8 minutes.

Once fully browned, drain excess grease to prevent the casserole from becoming oily.

Step 3: Add Aromatics and Vegetables

To the cooked beef, add:

  • Chopped onion
  • Minced garlic
  • Diced bell pepper

Cook for 3 to 5 minutes until the vegetables soften and the onion becomes translucent.

Stir in the corn and drained diced tomatoes. Allow the mixture to cook for another 2 to 3 minutes.

Step 4: Season and Simmer

Add:

  • Tomato sauce
  • Salt
  • Black pepper
  • Paprika
  • Oregano
  • Chili powder (if using)

Stir thoroughly to combine. Reduce heat to low and let the mixture simmer for 5 to 7 minutes. This allows the flavors to blend and excess moisture to evaporate slightly.

The filling should be thick, not watery.

Step 5: Add the Creamy Layer

If using sour cream or cream cheese, spread it evenly over the beef mixture once transferred to the baking dish. This adds a creamy contrast that balances the acidity of the tomatoes.

Sprinkle 1/2 cup mozzarella over this layer.

Step 6: Add the Cheese Topping

Top the casserole generously with:

  • 1 1/2 cups mozzarella
  • 1 cup cheddar

Distribute evenly to ensure full coverage. The combination of mozzarella for stretch and cheddar for flavor creates a beautifully melted top layer.

Step 7: Bake

Place the casserole in the preheated oven and bake uncovered for 20 to 25 minutes, or until:

  • Cheese is fully melted
  • Edges are bubbling
  • Top begins to turn golden

For extra browning, broil for 2 to 3 minutes at the end, watching carefully to prevent burning.

Step 8: Rest Before Serving

Remove from oven and allow the casserole to rest for 10 minutes. This helps the layers set and makes slicing easier.

Flavor Profile

This casserole is savory and slightly sweet from the corn and tomatoes. The beef provides richness, while the cheese adds creamy depth. The spices are mild but warm, making it family-friendly without sacrificing flavor.
