I like to cook my burgers at about 160 F, which is a well-done burger with no signs of pink on the inside. This is also the USDA recommended temperature for cooking burgers. However, if you use meat from a good source, you can cook burgers similar to steaks. For medium-well - cook about 4 minutes on the first side, then 3 minutes on the other side. (160 to 165 F) Medium - about 3 minutes on each side (150 to 155F) Medium rare - about 2 1/2 to 3 minutes on each side (130 to 135 F) Rare - about 2 minutes should do (120 to 125 F)
