A quick and easy method to transform leftover burger patties into juicy, crispy smash burgers with fresh toppings and melty cheese.
Do not skip the smashing step to get a crispy crust. Use a hot pan to avoid steaming. Mix butter with oil to prevent burning. Add cheese immediately after flipping. Avoid pressing patties after flipping to keep them juicy. If burgers stick, lower heat and add more butter. Cook in batches to avoid overcrowding. For smoky flavor, finish with a quick broil under the oven.
