Transport your taste buds to a tropical paradise with these teriyaki pineapple air fryer hamburgers. Start by marinating ground beef patties in teriyaki sauce for at least 30 minutes. Place the marinated patties in the air fryer basket and cook at 375°F for about 10-12 minutes, flipping halfway through. During the last few minutes of cooking, add a slice of pineapple to each patty and let it caramelize. Serve the burgers on toasted buns with lettuce, tomato, and a drizzle of teriyaki sauce. The combination of sweet and tangy teriyaki sauce with the juicy pineapple will give these air fryer hamburgers a unique and delicious flavor.
