Cook bacon until crispy. Drain most of bacon grease from pan and return to stove over medium-high heat.
Season ground beef with salt and pepper. Form into four evenly sized patties, about 3 ounces each.
Add patties to hot pan and immediate smash down; this allows the burgers to sear evenly and develop a nice crust. Cook for 2-3 minutes or until bottom of burgers are fully seared.
Flip burgers only once and cook second side for 1-2 minutes or until cooked through. Add a slice of cheese to each patty during the last 30 seconds of cooking, cover pan and allow cheese to melt.
Butter and toast Martin’s Slider Potato Rolls.
Top buns with cheeseburger, crispy bacon, fried onion strings, and barbecue sauce of choice.
