Smoked hamburgers have a different texture than burgers that have been cooked over high heat for a short amount of time. It’s not a bad texture by any means, but if you and your guests are expecting that great grill char, you’ll want to let them (the burgers) to spend a little time over high heat.
Fire up your smoker for cooking 225 F- 250 F. Use a light smoking wood, such as apple.
Form beef into patties and season well with salt and pepper.
Place burgers on smoker and cook 60-990 minutes or until beef reaches desired doneness (at least 150 F).
Note: Burgers will not have a char on them like you get when cooked over high heat. To get that great char, remove the burgers from the smoker when they reach 120 F and transfer to a hot grill to finish cooking.
