If you cook outdoors, just put the cutlets on the grill and fry on 2 sides.
There is also 1 secret burger, ideally, you need to flip no more than 2 times. That is, on the one hand, you let it fry well. On an open fire for about 5 minutes, turn over and fry for another 5.
Check with a knife - if there is juice, but no blood - your burger is ready. If there is a little blood - another 2 minutes on each side.
If you cook at home, then the principle is the same in a grill pan, only fry for 7 minutes + the roasting time is 3 minutes. Don't forget to add some olive oil.
