Step‑by‑Step Instructions for Stuffed Pepper Casserole Recipe

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures a perfectly cooked stuffed pepper casserole when you’re ready to bake. While the oven heats up, gather your ingredients and equipment, making sure you have a large skillet and a greased baking dish on hand.

Step 2: Brown the Beef
In a large skillet, heat a couple of tablespoons of olive oil over medium-high heat. Once hot, add the lean ground beef, cooking until it’s fully browned, about 6-8 minutes. Stir occasionally to break up the meat, ensuring it cooks evenly and sprouts that rich flavor that will elevate your stuffed pepper casserole.

Step 3: Sauté Vegetables
Add the diced yellow onion and bell peppers into the skillet with the browned beef. Sauté for 5-7 minutes until the vegetables are softened and fragrant. Then, stir in minced garlic, cooking for an additional minute. The mixture will become beautifully aromatic, signaling that your stuffed pepper casserole is on its way!

Step 4: Season the Mixture
Once the vegetables have softened, sprinkle in the Italian seasoning, Worcestershire sauce, salt, and ground black pepper. Stir well to combine all the flavors, and let the mixture simmer for a minute to allow the seasonings to bloom, adding a delightful depth to your stuffed pepper casserole.

Step 5: Combine Rice and Broth
Pour in the canned diced tomatoes (with their juices), uncooked long grain white rice, and beef broth. Stir everything together and bring the mixture to a boil over medium-high heat. Once bubbling, reduce the heat to low, cover, and simmer for 20 minutes. This step allows the rice to absorb all the delicious flavors and moisture from the stuffed pepper casserole.

Step 6: Assemble the Casserole
After 20 minutes, check that the rice is tender. If necessary, transfer the mixture into a greased baking dish, spreading it evenly. Top the mixture generously with shredded cheese, adding that creamy, melted layer that makes the stuffed pepper casserole irresistibly comforting.

Step 7: Bake
Place the baking dish in the preheated oven and bake for 25 minutes or until the cheese is bubbly and golden. You’ll know it’s done when the cheese has melted beautifully on top, making your stuffed pepper casserole a feast for the eyes as well!

Step 8: Rest and Garnish
Once out of the oven, let the casserole rest for about 5 minutes. This helps the flavors settle and makes serving easier. Before serving, sprinkle freshly chopped parsley on top for a touch of freshness and vibrant color, elevating your stuffed pepper casserole to something truly special.

Freezer: For longer storage, freeze your stuffed pepper casserole in airtight containers for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating: When ready to enjoy, reheat individual portions in the microwave for 2-3 minutes or in the oven at 350°F until heated through.
