What is a Stuffed Pepper Casserole?

It delivers the same great taste with much less effort, making it ideal for those who love stuffed peppers but want to cut down on prep time. This comforting dish brings together hearty ingredients, creating a balanced meal that’s rich in protein, fiber, and flavor.

The beauty of a stuffed pepper casserole is its versatility. Here are some substitutions and variations you can try to make it suit your tastes and dietary needs:

Step-by-Step Cooking Instructions

Ready to make the best stuffed pepper casserole ever? Follow these easy step-by-step instructions:

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with a little olive oil or non-stick spray and set it aside.

Step 2: Cook the Rice

Cook 1 cup of rice according to package instructions. Once cooked, set it aside. You can use any rice you prefer—white, brown, or even a grain alternative like quinoa.

Step 3: Sauté the Vegetables

In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced onions and sauté until they’re soft and translucent, about 3-5 minutes. Add the minced garlic and cook for another minute until fragrant. Then, toss in the chopped bell peppers and cook for an additional 5 minutes until they start to soften.

Step 4: Brown the Ground Meat

Push the vegetables to the side of the skillet and add the ground beef. Cook until browned, breaking it up with a wooden spoon as it cooks, about 6-8 minutes. If you’re using a fattier cut of meat, drain any excess grease before moving on.

Step 5: Season the Mixture

Once the meat is fully cooked, mix the meat with the sautéed vegetables. Season with salt, pepper, Italian seasoning, and paprika (if using). Stir everything together to ensure the spices coat the meat and vegetables evenly.

Step 6: Add Tomato Sauce and Broth

Pour in the tomato sauce and beef broth. Stir well to combine and bring the mixture to a simmer. Let it cook for about 5-7 minutes, allowing the flavors to meld together. If the mixture looks too dry, you can add a little more broth or water.

Step 7: Assemble the Casserole

In the prepared baking dish, layer the cooked rice at the bottom. Pour the meat and pepper mixture evenly over the rice. Sprinkle the shredded cheese on top to cover the entire casserole.

Step 8: Bake the Casserole

Cover the baking dish with foil and bake in the preheated oven for 25 minutes. After 25 minutes, remove the foil and bake for another 10-15 minutes, or until the cheese is bubbly and golden brown.

Step 9: Garnish and Serve

Once the casserole is out of the oven, let it sit for about 5-10 minutes before serving. Garnish with fresh parsley or cilantro for a pop of color and extra flavor.

Common Mistakes to Avoid

Here are some common mistakes people make when preparing stuffed pepper casserole—and how you can avoid them:

• Overcooking the Rice: Make sure to cook the rice just until it’s done, as it will continue to absorb moisture when baking. Overcooking the rice beforehand can make it mushy.
• Not Draining Fat: If you’re using a fattier cut of meat, be sure to drain any excess fat from the skillet after browning the meat to avoid a greasy casserole.
• Using Raw Bell Peppers: Don’t skip the step of sautéing the bell peppers. If you don’t cook them before baking, they can remain too crunchy in the final dish.
• Cheese Overload: While cheese is delicious, too much can make the dish overly greasy. Stick to about 1 ½ cups of cheese unless you’re looking for a particularly indulgent dish.

Serving and Presentation Tips

When it comes to serving your stuffed pepper casserole, a little extra care can make the dish even more appetizing. Here are some tips:

How to Serve Stuffed Pepper Casserole

• Individual Portions: Use a large spoon to scoop out generous portions. Serve it with a side of crusty bread or a simple green salad for a complete meal.
• Toppings: Add some extra toppings like sour cream, chopped green onions, or a sprinkle of red pepper flakes for a bit of a kick.

Presentation Ideas for Stuffed Pepper Casserole

• Cast-Iron Skillet: If you want a rustic look, you can bake and serve the casserole in a cast-iron skillet.
• Colorful Garnishes: Brighten up the dish with a sprinkle of fresh parsley or cilantro, or even some diced bell peppers that weren’t included in the casserole itself.
• Family-Style Serving: Present the entire baking dish at the table and let everyone serve themselves—this dish is perfect for a relaxed, family-style dinner.

Stuffed Pepper Casserole Recipe Tips

• Make Ahead: You can assemble the casserole ahead of time and store it in the refrigerator until you’re ready to bake. Just cover tightly and refrigerate for up to 24 hours. Bake as instructed when ready.
