Equipment

  • Oven

Method
 

  1. Preheat oven: Set oven to 350°F (180°C). Use a large oven-safe skillet or casserole dish.
  2. Brown beef: Heat olive oil, add ground beef, and cook until no longer pink. Drain excess fat.
  3. Sauté veggies: Stir in onion and peppers, cooking 2–3 minutes until softened.
  4. Season: Add garlic, seasoning, Worcestershire, salt, and pepper. Cook 30 seconds until fragrant.
  5. Build the base: Stir in diced tomatoes, rice, and beef broth. Bring to a gentle boil.
  6. Bake: Cover with lid or foil, transfer to oven, and bake 20–25 minutes until rice is tender.
  7. Top with cheese: Remove lid, sprinkle cheese on top, and broil 3–5 minutes until melted and bubbly.
  8. Garnish & serve: Sprinkle parsley on top and serve warm.

Notes

Use long-grain rice—short-grain may turn mushy.
For spicier flavor, try Cajun seasoning, hot sausage, or red pepper flakes.
To prevent soggy peppers, sauté briefly before baking (no more than 3 minutes).
Broil uncovered at the end for extra golden cheese.
