Preheat your oven to 350°F (180°C). Warm the olive oil in a heat-resistant skillet or pan over medium-high heat. Add the ground beef and sauté, breaking it apart with a spatula, until fully browned. Drain any excess fat.
Incorporate the diced onion and both bell peppers into the skillet. Cook for 2–3 minutes until the vegetables soften slightly.
Stir in the minced garlic, seasoning, Worcestershire sauce, salt, and black pepper, cooking for an additional 30 seconds. Add the canned diced tomatoes and mix thoroughly.
Pour in the rice and beef broth, stirring well. Allow the mixture to come to a boil. Cover with a lid or foil if using a casserole dish without a lid.
Transfer the pan to the preheated oven and bake for 20–25 minutes, or until the rice is tender. Check the rice for doneness; if it’s still firm, add a splash of water and bake for a few more minutes as needed.
Remove the skillet from the oven and evenly sprinkle the shredded cheese on top. Place the skillet back under the broiler for 3–5 minutes until the cheese is melted and bubbly.
Garnish with fresh parsley before serving.
