Step‑by‑Step Instructions for Stuffed Pepper Casserole

Step 1: Brown the Meat and Onion
In a large pot, heat a drizzle of oil over medium-high heat. Add 1 pound of ground beef and 1 diced onion, cooking until the beef is browned and the onion is soft, about 5-7 minutes. Be sure to drain off any excess grease to keep your casserole from becoming oily. The beef should be fully cooked and no longer pink.

Step 2: Sauté the Vegetables
Stir in 3 cloves of minced garlic and 2 diced bell peppers into the pot, cooking for an additional 5 minutes. Keep the heat on medium until the peppers are tender and vibrant, stirring occasionally to ensure even cooking. This will infuse your Stuffed Pepper Casserole with wonderful aroma and flavor.

Step 3: Add the Flavorings
Mix in 1 tablespoon of Italian seasoning, 1 teaspoon of sea salt, and 1 teaspoon of black pepper to the pot, stirring well to combine all the ingredients. Then, pour in 1 cup of tomato sauce, 14.5 ounces of diced tomatoes, 2 tablespoons of soy sauce, and 1 cup of beef broth. Allow the mixture to simmer until warmed through, approximately 2-3 minutes.

Step 4: Incorporate the Rice
Bring the entire mixture to a gentle boil, then stir in 1 cup of uncooked rice. Reduce the heat to medium-low, cover the pot, and let it simmer undisturbed for 15 minutes. The rice will absorb the liquid, becoming plump and tender, which is essential for the richness of your Stuffed Pepper Casserole.

Step 5: Melt the Cheese
Once the rice is cooked and the liquid has been absorbed, remove the pot from the heat and stir in 1 ½ cups of shredded cheese until it’s completely melted. For a bubbly, cheesy topping, you can transfer the casserole to a baking dish at this point, top with the remaining cheese, and broil for an extra 3-5 minutes until golden and bubbling.

Step 6: Serve and Savor
Once the casserole is perfectly melted and bubbly, remove it from the oven and allow it to cool for a few minutes. Serve your Stuffed Pepper Casserole warm, and watch as your family enjoys this delightful, comforting dish bursting with flavor.

Expert Tips for Stuffed Pepper Casserole

Ingredient Substitutions: If you’re out of beef, ground turkey or even black beans can work wonders without losing flavor in your stuffed pepper casserole.
Cook Rice Properly: Ensure the rice is uncooked when adding to the pot; this helps it absorb all the flavorful liquids and prevents a mushy texture.
Enhance Flavor: For a richer taste, consider adding a splash of red wine along with the broth before simmering.
Perfect Cheese Melt: Stir in cheese off the heat to prevent it from clumping; for a cheesy crust, transfer your casserole to a dish and broil briefly for that golden finish.
Prevent Greasiness: Drain excess grease from the cooked beef thoroughly to keep your casserole light and avoid sogginess.

Make Ahead Options

These Easy Stuffed Pepper Casserole components are exceptional for meal prep! You can chop the bell peppers and onions, and store them in an airtight container in the refrigerator up to 3 days in advance, preserving their freshness and crunch. Additionally, you can brown the ground beef and mix in the seasonings up to 24 hours before cooking—just store everything in the fridge until you’re ready to finish. When it’s time to prepare your casserole, simply combine the meat mixture with the rice, broth, and tomatoes, and follow the usual cooking instructions. This approach saves time on busy weeknights while ensuring your casserole is just as delicious as if freshly cooked!
