Do not overcrowd the air fryer basket. If you have a small air fryer, cook the burgers in batches.- Use a meat thermometer to check if the burgers are cooked through. The internal temperature should be at least 160 degrees F.- For extra flavor, brush the burgers with BBQ sauce or your favorite seasoning before cooking.- If you want to add cheese to your burgers, do it during the last minute of cooking.- Serve the burgers on warm burger buns and top with your favorite toppings.
