Remove the ribeye from the refrigerator 30 minutes before cooking to allow it to reach room temperature for even searing.
Pat the steak completely dry with paper towels and season both sides generously with sea salt and black pepper.
Finely mince the fresh rosemary, thyme, and garlic clove, then set them aside.
Heat a cast-iron skillet over medium-high heat and add the ghee, allowing it to melt until it begins to shimmer.
Place the steak in the hot skillet and sear for 3-4 minutes per side for medium-rare, or until a deep golden crust forms.
During the last 2 minutes of cooking, add the grass-fed butter, minced garlic, rosemary, and thyme to the pan.
Tilt the pan slightly and use a spoon to continuously baste the steak with the foaming herb butter.
Remove the steak from the pan and let it rest on a cutting board for 5-10 minutes before slicing against the grain.
