Creating your Ground Beef & Rice Casserole is as simple as following these straightforward steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook Beef: In a large skillet, heat the olive oil over medium-high heat. Add the ground beef and cook until browned, about 5-7 minutes.
3. Add Onions and Garlic: Stir in the chopped onion and minced garlic, cooking until softened and fragrant, around 2-3 minutes.
4. Incorporate Vegetables: Add the chopped bell peppers and cook for another 2-3 minutes until they are tender.
5. Mix in Seasonings: Sprinkle the chili powder, cumin, paprika, salt, and pepper over the mixture, stirring to combine.
6. Stir in Rice and Tomatoes: Incorporate the rice, canned diced tomatoes (with juice), and kidney beans into the skillet, mixing well.
7. Add Broth: Pour the beef broth into the mixture, ensuring everything is evenly distributed.
8. Transfer to Baking Dish: Carefully transfer the mixture into a large greased casserole dish.
9. Top with Cheese: Sprinkle the shredded cheese evenly over the top of the casserole.
10. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and bubbly, and the rice is cooked through.
11. Cool and Serve: Once baked, let the casserole cool for a few minutes before serving.
