How to Make Stuffed Pepper Casserole

Preheat Oven & Prepare Skillet: Begin by preheating your oven to 375°F (190°C). Meanwhile, heat a drizzle of olive oil in a large skillet over medium-high heat, ensuring it’s hot and ready for the ingredients.
Brown the Beef: Add the lean ground beef to the heated skillet, using a wooden spoon to break it up. Cook for 5-7 minutes, stirring occasionally, until it’s browned and no longer pink.
Sauté Vegetables: Next, stir in the diced yellow onion and bell peppers, then add the minced garlic. Sauté the mixture for about 5-7 minutes until the onions turn translucent and the peppers are tender.
Season the Mixture: Now it’s time to introduce flavor! Mix in your chosen seasoning, Worcestershire sauce, salt, and ground black pepper. Stir well to combine all the seasonings with the meat and veggies.
Add Tomatoes and Rice: Pour in the canned diced tomatoes along with the uncooked long grain white rice, ensuring everything is well mixed. This is the foundation of your casserole!
Incorporate Broth: Gradually add the beef broth to the mixture. Bring it to a gentle boil, then cover and reduce the heat to simmer for around 20 minutes, allowing the rice to cook and absorb all those wonderful flavors.
Transfer to Casserole Dish: Once the rice is cooked, carefully transfer the mixture to a greased casserole dish. Top it generously with shredded cheese, making it wonderfully melty when baked.
Garnish & Serve: Bake in the preheated oven for 15-20 minutes, until the cheese is fully melted and bubbly. Once done, remove it from the oven, let it cool for a few moments, and finish with a sprinkle of fresh parsley before serving.

Optional: Pair with garlic bread or a mixed green salad for a complete meal.
