Step‑by‑Step Instructions for Stuffed Pepper Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms, grab a 9×13-inch baking dish and lightly grease it with cooking spray or olive oil to prevent sticking. This will ensure that your Easy Stuffed Pepper Casserole releases easily after baking, keeping it intact for serving.
Step 2: Cook Meat and Veggies
In a large skillet over medium heat, add a splash of olive oil, then toss in the ground beef. Cook for about 5-6 minutes, breaking it up into small pieces as it browns. When the beef is nearly cooked through, add the diced onion and chopped bell peppers, sautéing until the vegetables are tender and the beef is no longer pink. Drain any excess grease.
Step 3: Add Aromatics and Seasoning
Stir in minced garlic, Italian seasoning, paprika, salt, and black pepper into the beef and veggie mixture. Cook for an additional 1-2 minutes until the garlic is fragrant and golden, infusing the casserole with delicious flavors. This aromatic base is key to enhancing the taste of your Stuffed Pepper Casserole.
Step 4: Combine Ingredients
Now, it’s time to stir in the uncooked rice, diced tomatoes along with their juices, tomato sauce, and beef broth. Mix everything together thoroughly until well combined. The moisture from the tomatoes and broth will cook the rice during baking, resulting in a creamy casserole that perfectly complements the other ingredients.
Step 5: Bake the Casserole
Transfer the mixture into your prepared baking dish, spreading it evenly. Cover the dish tightly with aluminum foil to trap steam, which helps cook the rice evenly. Place it in the preheated oven and bake for 45-50 minutes. You’ll know it’s ready when the rice is tender and the mixture is bubbling around the edges.
Step 6: Add Cheese
Once the casserole is cooked, carefully remove the foil, revealing a steamy, colorful dish. Sprinkle your choice of shredded mozzarella or cheddar cheese generously over the top. Return the dish to the oven and bake for an additional 10 minutes, or until the cheese is melted and bubbly, creating a gorgeous, gooey topping.
Step 7: Serve the Casserole
After baking, take the Easy Stuffed Pepper Casserole out of the oven and let it rest for about 5 minutes. This allows the flavors to meld and makes serving easier. Once slightly cooled, scoop portions into bowls or plates and enjoy the comforting, hearty goodness chock-full of colorful veggies and savory flavors!

Make Ahead Options
These Stuffed Pepper Casserole components are ideal for prepping in advance, saving you precious time during busy weeknights! You can cook the meat and sauté the vegetables up to 24 hours beforehand; simply refrigerate the mixture in an airtight container. Additionally, you can combine the rice, tomatoes, tomato sauce, and broth in advance—just keep this mixture refrigerated for up to 3 days. When you’re ready to bake, layer the prepped ingredients in the greased baking dish, cover with foil, and bake as directed. This method ensures that your casserole remains just as delicious, offering a comforting meal with minimal effort when it’s time to serve!
