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
