Instructions

1. Preheat oven: Set oven to 350°F (180°C).
2. Cook the beef: In a skillet or heat-resistant pan over medium-high heat, heat olive oil. Add ground beef and cook, breaking it apart with a spatula, until no longer pink. Drain excess fat.
3. Add vegetables: Stir in onion, red bell pepper, and green bell pepper. Cook 2–3 minutes until slightly softened.
4. Season and combine: Add garlic, Italian or Cajun seasoning, Worcestershire sauce, salt, and black pepper. Cook for 30 seconds until fragrant. Stir in diced tomatoes.
5. Add rice and broth: Mix in uncooked rice and beef broth. Stir well and bring to a boil. Cover with a lid or foil if using a casserole dish without a lid.
6. Bake: Place the covered dish in the oven and bake for 20–25 minutes. Check rice for doneness; if still slightly firm, return to oven and add a splash of water if needed.
7. Add cheese: Remove casserole from oven, sprinkle shredded cheese on top, and place under the broiler for 3–5 minutes until cheese is melted and bubbly.
8. Serve: Garnish with fresh parsley and serve hot.
