Ground Beef Casserole

Step 2: Cook the Ground Beef

In a large skillet over medium heat, add 2 tablespoons of olive oil. Once hot, add the chopped onions and cook for 2–3 minutes until translucent. Add the garlic and sauté for another minute until fragrant.

Add the ground beef, breaking it apart with a spatula. Cook until browned, about 5–7 minutes. Drain any excess fat if necessary.

Step 3: Season and Add Vegetables

Season the beef mixture with salt, black pepper, paprika, oregano, and basil. Stir well to combine.

Add the bell peppers, mushrooms, diced tomatoes, and frozen corn. Let it simmer for 5–7 minutes, allowing the flavors to meld and the vegetables to soften slightly.

For a creamier texture, stir in sour cream or cream cheese at this stage.

Step 4: Layer the Base

If you’re using pasta, rice, or mashed potatoes as the base, layer it evenly at the bottom of the prepared baking dish. This layer acts as a hearty foundation that soaks up the flavorful beef mixture.

Step 5: Assemble the Casserole

Spoon the beef and vegetable mixture over the base layer, spreading it evenly. Top the casserole with a generous layer of shredded cheese, covering all corners. This will melt into a golden, gooey topping during baking.

Step 6: Bake

Place the casserole in the preheated oven and bake for 20–25 minutes, or until the cheese is melted and slightly golden on top. For an extra-crispy top, switch the oven to broil for 2–3 minutes at the end, but watch carefully to prevent burning.

Step 7: Rest and Serve

Remove the casserole from the oven and let it rest for 5–10 minutes before serving. This allows the layers to set slightly, making it easier to cut and serve.

Serve hot, garnished with fresh parsley or chopped green onions if desired. Pair it with a side salad or garlic bread for a complete meal.

Tips for the Perfect Ground Beef Casserole

1. Customize your vegetables – zucchini, carrots, or spinach can be great additions.
2. Make it spicy – add a pinch of chili flakes or hot sauce.
3. Cheese variation – try a mix of cheddar and mozzarella or add Parmesan for extra flavor.
4. Make ahead – assemble the casserole a day in advance and refrigerate. Bake fresh before serving.
