Preheat oven to 425 degrees F. Wrap top of baking sheet with foil and lay a wire rack on top. Place as many frozen burgers on top without overlapping as you want.
Sprinkle all with salt and pepper and bake for 15 minutes. Open oven and flip each one over on to the other side.
Continue baking for another 10 minutes. If you want to add cheese add 1 slice on each now and bake for 1 minute to melt. Remove, sprinkle with salt and pepper again and serve on buns.
