Step-by-Step Cooking Instructions

Let’s get into the step-by-step instructions to make this delicious Quick and Simple Stuffed Pepper Casserole.
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with cooking spray or oil.
Step 2: Brown the Ground Beef
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the ground beef and cook until browned, breaking it up with a wooden spoon as it cooks (about 5-7 minutes). Season with salt and pepper to taste. Once cooked, drain off any excess fat and transfer the beef to a plate.
Step 3: Sauté the Vegetables
In the same skillet, add the chopped onion and bell peppers. Cook for about 5-6 minutes until the vegetables soften. Add the minced garlic and cook for another 1-2 minutes, until fragrant.
Step 4: Add the Rice and Liquids
Once the vegetables are softened, stir in the uncooked rice, diced tomatoes, tomato sauce, and beef broth. Add the Italian seasoning, paprika, and additional salt and pepper to taste. Bring the mixture to a simmer, stirring occasionally, and let it cook for about 5 minutes to allow the flavors to combine.
Step 5: Combine and Transfer to the Baking Dish
Add the cooked ground beef back into the skillet and stir everything together until well combined. Transfer the mixture to your prepared baking dish, spreading it out evenly.
Step 6: Bake the Casserole
Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 25-30 minutes, or until the rice is tender and the liquid has absorbed. Check the casserole halfway through to make sure the rice is cooking evenly, and stir if necessary.
Step 7: Add the Cheese
Once the rice is cooked, remove the foil and sprinkle the shredded cheddar cheese evenly over the top of the casserole. Return the dish to the oven, uncovered, and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Step 8: Garnish and Serve
Remove the casserole from the oven and let it rest for a few minutes before serving. Garnish with fresh parsley if desired, and serve hot.
How to Cook Quick and Simple Stuffed Pepper Casserole: A Step-by-Step Guide
To recap the steps:
- Preheat the oven to 375°F and grease a 9x13-inch baking dish.
- Brown the ground beef in a skillet, season, and drain any excess fat.
- Sauté onions, bell peppers, and garlic until softened.
- Add the rice, diced tomatoes, tomato sauce, broth, and seasonings, and simmer for 5 minutes.
- Combine the ground beef with the rice mixture and transfer to the prepared baking dish.

Common Mistakes to Avoid
While this casserole is straightforward, here are a few common mistakes to avoid:
- Not draining excess fat: After browning the ground beef, make sure to drain any excess fat to avoid a greasy casserole.
- Undercooked rice: If the casserole dries out before the rice is fully cooked, check the liquid level during baking. If needed, add a bit more broth and stir.
- Skipping foil: Be sure to cover the casserole with foil while baking to trap steam and ensure the rice cooks evenly.
- Overcooking the vegetables: Don’t cook the peppers and onions too long before baking. They should still have a bit of crunch when you add them to the casserole.
Serving and Presentation Tips
Here are some ways to serve and present your Stuffed Pepper Casserole for maximum appeal.
How to Serve Stuffed Pepper Casserole
- With a Side Salad: Pair the casserole with a simple green salad or Caesar salad for a refreshing contrast.
