Directions: stuffed bell pepper casserole

1. Preheat the oven to 350°F (175°C). This is the perfect temperature for baking your casserole to perfection, ensuring it cooks evenly and brings all those flavors together.
2. Brown the ground beef in a large skillet over medium heat. Drain excess fat after cooking, which helps keep your dish lean and flavorful, setting the stage for a hearty meal.
3. Sauté the diced onion and minced garlic in the skillet until the onion turns translucent. This aromatic duo will enhance the flavor of your casserole and fill your kitchen with a delightful scent.
4. Stir in the uncooked rice, diced tomatoes, beef broth, Italian seasoning, salt, and black pepper. Bring everything to a boil, allowing those bold flavors to meld together beautifully for about 10 minutes.
5. Reduce the heat and let it simmer for about 10 minutes or until the rice is partially cooked. This step ensures that each grain of rice absorbs all that savory goodness before being baked.
6. Add the chopped bell peppers to the skillet and mix well. Their vibrant colors will brighten up your casserole while giving it that classic stuffed bell pepper flavor everyone loves.
7. Transfer the mixture to a casserole dish and spread it evenly across the bottom. This creates a solid base for your delicious layers—your family won't be able to resist!
8. Sprinkle shredded cheese on top of your mixture. Choose between cheddar or mozzarella; either will create a gooey, melty topping that adds an irresistible finish.
9. Cover with foil and bake in the preheated oven for 30 minutes. This helps retain moisture, making sure your casserole stays juicy and tender throughout its bake.
10. Remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown. This final touch gives you that deliciously crispy topping that's simply irresistible!
Optional: Top with fresh herbs like parsley or basil before serving for an added burst of flavor!
