This stuffed pepper casserole is a one-pan skillet dinner loaded with beef, peppers, rice, and melty cheese. Easy to make, full of flavor, and perfect for a weeknight meal the whole family will love.
In a large skillet, cook the ground beef, onion, and bell peppers over medium heat until the beef is browned and cooked through. Drain any excess grease.
Stir in the garlic, Italian seasoning, salt, and pepper. Cook for 1 minute, stirring often, until fragrant.
Pour in the beef broth, tomato sauce, fire-roasted diced tomatoes, and Worcestershire sauce. Stir to combine. Add the rice, cover the skillet with a lid, and reduce the heat to low. Simmer for about 25-30 minutes, or until the rice is tender and most of the liquid is absorbed.
Remove the skillet from the heat. Stir in ½ cup cheddar cheese and ¼ cup pepper jack until melted. Sprinkle the remaining cheese evenly over the top, cover for a few minutes, and let it melt before serving.
