Heat the pan. 1  Place a few tablespoons of vegetable or olive oil in a non-stick pan and allow the pan to warm up over medium heat for about 5 minutes. 2  Heating the pan before adding the burgers will help your burgers brown and develop a brown sear on the outside that will enhance the flavor.. Place the burgers in the pan. 1  Add all of the burgers to the pan at the same time so they will cook to roughly the same internal temperature. 2  If you're making a lot of burgers, cook them in batches. 3  Space the burgers out in the pan so there is a little room between them.
