Instructions
Step 1: Prepare the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
Step 2: Cook the Beef
Heat the olive oil in a large skillet over medium-high heat.
Cook the onion for 3–4 minutes until softened.
Add the garlic and cook for 30 seconds.
Add the ground beef and cook until browned, breaking it apart with a spoon. Drain excess grease if needed.
Step 3: Add the Vegetables
Stir in the sliced bell peppers and cook for 5 minutes, allowing them to soften slightly while keeping a little crunch.
Mix in the diced tomatoes, tomato paste, Italian seasoning, smoked paprika, chili powder, salt, and black pepper.
Simmer for 8–10 minutes until slightly thickened.
Step 4: Assemble the Bake
Transfer the beef mixture to the prepared baking dish.
Sprinkle the mozzarella, cheddar, and Parmesan cheeses evenly over the top.
Step 5: Bake
Bake for 15–20 minutes, or until the cheese is melted, bubbly, and lightly golden.
For a beautifully browned top, broil for 2–3 minutes before removing from the oven.
Step 6: Serve
Garnish with fresh parsley or basil and serve hot.
