Heat a large oven-safe skillet over medium heat. Add ground beef and cook, breaking it apart, until browned. Drain excess fat if needed.
Add chopped bell peppers and onion. Cook for 3–4 minutes until slightly softened.
Stir in uncooked rice, diced tomatoes, beef broth, salt, pepper, and paprika. Mix well.
Bring to a gentle simmer, cover, and cook for 25–30 minutes, stirring once halfway through, until rice is tender.
Sprinkle shredded cheese over the top. Cover and cook for 5 minutes, or until cheese melts.
Remove from heat and rest for 5 minutes before serving.
