01 -
Turn your air fryer on to 190°C and give it a few minutes to get ready.
02 -
Mix the beef, salt, and pepper well. Make four patties that are just a bit bigger than the buns.
03 -
Put the patties flat in the air fryer basket. Let them cook for 10 to 12 minutes, flipping once in the middle. Make sure they hit 70°C inside.
04 -
Lay the cheese on the patties a couple of minutes before they’re done so it can melt.
05 -
If you like, toast the buns. Add the patties and any extras you want like lettuce, tomatoes, and onions.
