First Step: Gather and Prepare Ingredients Start by assembling all ingredients: ground beef, finely diced onion and bell pepper, eggs, seasonings, Worcestershire sauce, and your choice of cheese. Make sure the cheese is cut into 1/2 inch cubes or shredded, depending on your preference. If adapting for vegan or gluten-free diets, have substitutions ready.

Second Step: Mix the Burger Meat In a large mixing bowl, gently combine the ground beef with diced onion, diced bell pepper, eggs, Cajun seasoning, onion powder, garlic powder, Accent seasoning (if using), and Worcestershire sauce. Mix carefully to incorporate all ingredients without overworking the meat, which can make patties tough.

Third Step: Form the Patties Divide the meat mixture into even portions, shaping each into a patty slightly larger than your desired final size since they will shrink while cooking. Place a cube or spoonful of cheese in the center of each patty, then fold and seal the meat around the cheese completely, tucking and pressing the edges to prevent leakage during cooking.

Fourth Step: Preheat the Air Fryer Set your air fryer to 370°F (188°C) and allow it to preheat. Spray the air fryer basket lightly with nonstick cooking spray or a light oil to prevent sticking and ease cleanup.

Fifth Step: Cook the Stuffed Burgers Arrange the patties in the air fryer basket in a single layer without overcrowding to ensure proper air circulation. Cook for 8 minutes at 370°F, then carefully flip each burger and cook for an additional 3 to 5 minutes. Use a meat thermometer to check that the internal temperature reaches 160°F (71°C) for safe doneness.

Sixth Step: Rest and Serve Remove the burgers from the air fryer and let them rest for about 5 minutes. This resting period helps juices redistribute for moist, flavorful burgers. Serve on buns or wrapped in lettuce for a low-carb option, and add your favorite toppings such as lettuce, tomato, pickles, or condiments.
