Add the ghee and seasonings and mix until well combined.
Form into four similar sized patties and place on a plate. Transfer to the refrigerator for 10-15 minutes while the grill heats up.
Heat an outdoor grill to a medium-hot heat. Once hot, place the burgers on the grill and cook for about 3-4 minutes per side or until medium-rare to medium (an internal temperature of 135-140°F is achieved). Alternatively, you can cook the burgers on a cast iron skillet on the stove top over medium-high heat using a touch of ghee or butter in the pan.
If using the cheddar, place a slice on top of each burger about 1 minute before removing the burgers from the grill. Make sure to close the lid of the grill so the cheese melts.
Serve burgers with chosen toppings on a bun if desired.
