How can I cook hamburgers in a cast iron skillet?

To cook Hamburgers in a cast iron skillet, preheat the skillet over medium-high heat. Season the patties with salt and pepper, then place them in the skillet. Cook for about 4-5 minutes on each side, or until they reach your desired level of doneness. Make sure to flip the burgers only once to develop a nice crust. Serve the burgers on buns with your favorite toppings.
