1-Getting started with this stuffed pepper casserole beef is straightforward and fun: Begin by preheating your oven to 375 degrees Fahrenheit and greasing a 9×13 casserole dish with nonstick spray. This sets the stage for a dish that’s full of flavor and easy to assemble.

2-In a large pan over medium heat, brown the 1 pound of lean ground beef until it’s fully cooked. Once that’s done, add the diced bell peppers and onion, cooking them together until they soften. This step builds a solid base of flavors that make the casserole stand out.

3-Next, stir in the minced garlic, Worcestershire sauce, salt, pepper, paprika, and grill seasoning to amp up the taste. Then, mix in the beef broth, diced tomatoes, uncooked rice, and 1 and ½ cups of shredded cheese, saving the rest for the top. Pour everything into your prepared dish, add the remaining cheese, and cover with foil.

4-Detailed Cooking Steps: Bake the casserole for about 45 minutes, checking until the liquid is absorbed and the cheese is melted and bubbly. If you want a golden top, remove the foil and broil for 3-5 minutes. Let it rest for 10 minutes before serving to let the flavors settle.
