Step-by-Step Instructions
1. Sauté the Base
Heat your skillet over medium heat. Brown the ground beef or turkey until fully cooked, then drain excess fat. Stir in the diced onion and garlic, cooking for 2-3 minutes until fragrant.
2. Add Peppers and Seasoning
Toss in the diced bell peppers and sauté for 3-4 minutes, allowing them to soften slightly. Add the Italian seasoning, paprika, salt, and pepper.
3. Combine the Sauce
Pour in the diced tomatoes, tomato sauce, and broth. Stir to combine and let it simmer for 5-7 minutes to meld the flavors.
4. Mix in Rice
Gently fold in the cooked rice until well combined. Taste and adjust seasonings as needed.
5. Assemble the Casserole
Preheat your oven to 375°F (190°C). Transfer the mixture into a greased 9×13-inch baking dish, smoothing the top. Sprinkle evenly with shredded mozzarella.
6. Bake to Perfection
Bake uncovered for 20 minutes, or until the cheese is bubbly and golden brown.
7. Garnish and Serve
Let the casserole rest for 5 minutes. Garnish with fresh parsley or basil before serving.

Tips for Success
- Prep Ahead: Dice veggies and cook the rice in advance to save time.
- Avoid Overcooking: Don’t let the bell peppers get too soft—they should retain a bit of crunch.
