Step‑by‑Step Instructions for Stuffed Pepper Casserole
Step 1: Brown the Meat
In a large pot or Dutch oven, heat a drizzle of olive oil over medium-high heat. Add 1 pound of lean ground beef along with 1 diced onion. Brown the meat for about 5-7 minutes, breaking it apart with a spatula until fully cooked, with no pink remaining. Drain any excess grease, allowing the rich flavors to remain.
Step 2: Add Aromatics
Once the meat is browned, stir in 3-4 minced garlic cloves and 3 diced bell peppers, mixing well. Cook for an additional 4-5 minutes until the peppers soften and the garlic becomes fragrant, transforming your kitchen into a delightful aroma haven. This step is crucial for layering the flavors in your Easy Stuffed Pepper Casserole.
Step 3: Season and Combine
Sprinkle in 1 teaspoon of Italian seasoning, ½ teaspoon of sea salt, and ¼ teaspoon of black pepper, stirring to evenly distribute the seasonings. Next, pour in 2 cups of beef broth, 1 can of diced tomatoes, and 1 can of tomato sauce, bringing the mixture to a vibrant boil. Stir occasionally to prevent sticking while the flavors meld beautifully.
Step 4: Cook Rice
Once boiling, add 1 cup of uncooked rice into the pot and stir everything together. Reduce the heat to medium-low, covering the pot. Allow it to simmer for approximately 15 minutes, or until the rice is tender and has absorbed most of the liquid, creating a cohesive filling for the casserole.
Step 5: Melt in Cheese
Remove the pot from heat and fold in 1.5 cups of shredded cheddar cheese until it melts into the casserole, creating a creamy and cheesy texture throughout. Make sure the cheese is evenly distributed to enhance the richness of your Stuffed Pepper Casserole.
Step 6: Finish Casserole
For a crispy cheese layer, sprinkle the remaining ½ cup of cheese on top of the casserole. Either cover for a minute until melted or transfer the mixture to a casserole dish and bake in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until the cheese is golden and bubbly, adding a delightful texture to your dish.

Make Ahead Options
These Easy Stuffed Pepper Casserole make-ahead options are perfect for busy home cooks looking to save time and minimize weeknight stress! You can prep the entire casserole up to 24 hours in advance by following the initial cooking steps, then allow it to cool completely before storing it in the refrigerator, covered tightly. For even better flavor, consider assembling the dish without cheese, adding it just before baking, which keeps it fresh and gooey. When ready to serve, simply bake it in a preheated oven for about 20-25 minutes (or until heated through), and enjoy a comforting, homemade meal with minimal effort!
