Stuffed Pepper Casserole is the ultimate comfort food that cooks on the stovetop in one pan! It captures all the flavor of classic stuffed peppers without the hassle.
In a large skillet, heat 1 tablespoon olive oil over medium-high heat. Add 1 ½ pounds ground beef and ½ diced yellow onion.
Sauté the onion while breaking apart the ground beef. Cook until the beef is no longer pink.
Drain excess fat, then add 1 diced green bell pepper and 1 diced red bell pepper. Cook for 2–3 minutes.
Add 2 cloves minced garlic (or 2 teaspoons minced garlic), 1 teaspoon salt, ½ teaspoon black pepper, and 1 teaspoon Italian seasoning. Stir to combine.
Stir in 1 tablespoon Worcestershire sauce, 14 oz diced tomatoes, 1 cup long grain rice, and 2 cups beef broth.
Stir everything together and bring to a boil.
Cover with a lid, reduce heat to medium, and simmer for 20–25 minutes until the rice is tender and the liquid is absorbed.
Once the rice is tender, turn off the heat. Sprinkle 1 ½ cups shredded mozzarella cheese on top, cover, and let sit until the cheese is melted.
Top with fresh parsley and serve. Enjoy!

Notes
Recipe Tips
Skillet - We used a regular skillet to make this. If you prefer to put the casserole in the oven, make it in a cast iron skillet so you can easily place it in the oven.
Cooking Time - This casserole cooks in about 30 minutes. It may take a little longer depending on how long it takes for the rice to get tender.
Make Ahead - Feel free to prepare the casserole ahead of time and then store it in the fridge until ready to finish cooking.
Variations Ideas
Tex-Mex Flavor - Add taco seasoning, corn, and black beans for a delicious variation.
Low-carb - Swap rice for cauliflower rice if you are looking for a low carb variation.
Vegetarian - Use lentils or quinoa instead of meat. You can even add in beans.
Spicy - Stir in diced jalapeños or a splash of hot sauce if you prefer a kick to the flavor.
