- 2 cloves garlic, minced

For the cheesy topping:

Instructions
Step 1: Prepare the Ingredients
Wash the bell peppers, remove their seeds, and slice them into thin strips. Peel and dice the onion, then mince the garlic.
Preheat your oven to 375°F (190°C).
Step 2: Cook the Ground Beef
Heat olive oil in a large skillet over medium heat. Add the ground beef and cook for approximately 6–8 minutes, breaking it apart with a wooden spoon.
Continue cooking until the beef is browned and fully cooked. Drain excess fat if necessary.
Step 3: Add the Vegetables
Add the diced onion, red pepper, green pepper, and yellow pepper to the skillet.
Cook for approximately 4–5 minutes until the vegetables begin to soften.
Stir in the minced garlic and cook for another 30 seconds until fragrant.
Step 4: Season the Mixture
Add tomato sauce, tomato paste, Italian seasoning, paprika, salt, black pepper, and onion powder.
Stir everything together until the ground beef and vegetables are evenly coated.
Allow the mixture to simmer for approximately 5 minutes so the flavors can combine.
Step 5: Prepare the Baking Dishes
Lightly grease two small oven-safe aluminum baking dishes or one medium casserole dish.
Divide the beef and pepper mixture evenly between the dishes.
Step 6: Add the Cheese
Sprinkle shredded mozzarella and cheddar generously over the top.
Finish with grated Parmesan if desired.
Step 7: Bake Until Golden
Place the dishes in the preheated oven and bake for approximately 12–15 minutes, or until the cheese is completely melted and bubbling.
For a beautifully golden top, broil for an additional 1–2 minutes while watching carefully.
Step 8: Rest and Serve
Remove from the oven and allow the casserole to rest for approximately 5 minutes.
Garnish with fresh parsley and serve warm.
Enjoy every cheesy, savory bite!
