Ingredients

• 500 g ground beef
• 1 small onion, finely chopped
• 2 garlic cloves, minced
• 1 red bell pepper, diced
• 1 cup crushed tomatoes or tomato sauce
• 1 teaspoon paprika
• ½ teaspoon black pepper
• Salt, to taste
• 1 teaspoon dried oregano or Italian seasoning
• 1 cup shredded mozzarella cheese
• ½ cup shredded cheddar cheese
• 2 tablespoons olive oil
• Fresh chopped parsley, for garnish

Instructions

Preheat your oven to 350°F (180°C) and lightly grease a medium-sized baking dish.

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook for about 3 to 4 minutes, stirring occasionally, until softened and translucent. Stir in the minced garlic and cook for another 30 seconds until fragrant.

Add the ground beef to the skillet, breaking it apart with a wooden spoon as it cooks. Continue cooking until the beef is fully browned and no longer pink. If necessary, drain any excess grease to keep the casserole from becoming oily.

Mix in the diced red bell pepper and cook for 2 to 3 minutes until it begins to soften. Pour in the crushed tomatoes or tomato sauce, then season the mixture with paprika, black pepper, salt, and dried oregano or Italian seasoning. Stir everything together and let the mixture simmer for 5 to 7 minutes, allowing the flavors to blend and the sauce to thicken slightly.

Transfer the beef mixture evenly into the prepared baking dish. Sprinkle the shredded mozzarella cheese over the top, followed by the cheddar cheese, making sure the surface is completely covered.

Bake the casserole uncovered for 20 to 25 minutes, or until the cheese is fully melted, bubbly, and lightly golden around the edges.

Remove the casserole from the oven and let it rest for about 5 minutes before serving. Garnish with freshly chopped parsley for added color and freshness.

Tips for Success

• Use lean ground beef to reduce excess grease.
• Freshly shred the cheese for the smoothest melt and best flavor.
• Simmer the meat mixture before baking to create a richer, thicker sauce.
• Allow the casserole to rest briefly after baking so it slices and serves more easily.
• For extra flavor, add a pinch of red pepper flakes or a dash of Worcestershire sauce to the meat mixture.

Variations

• Layer cooked pasta between the meat and cheese to create a hearty pasta bake.
• Add sliced cooked potatoes or hash browns for a filling one-dish meal.
• Mix in vegetables such as mushrooms, zucchini, spinach, or corn for extra nutrition.
• Substitute ground turkey or chicken for a lighter version.
• Add Parmesan cheese on top before baking for an extra crispy, cheesy crust.

Serving Suggestions

This cheesy ground beef casserole pairs wonderfully with warm garlic bread, steamed rice, mashed potatoes, roasted vegetables, or a crisp green salad. It also makes an excellent filling for baked potatoes or can be served over buttered egg noodles for a satisfying meal.

Storage
