Just had something similar happen. Here is my “fix”: Cook your burger as you would. Pull it at the desired time for cheese. Place cheese on burger, give a slight press so that it engages fully. Close the drawer of air fryer and LEAVE IT OFF for at least thirty seconds so the cheese has a chance to bond. Then restart air fryer to complete the process. Hopefully this solves the problem for the next cheeseburger should you ever emotionally recover.
i’ve never tried air frying burgers. how’s it compare to a grill or pan?
