In this video, we learn how to make marinated grilled king crab legs. First, heat up 1/4 c butter in a pan, then add in some lemon juice and dried parsley. Mix all of these together in the pan until it's all combined then add in some Dijon mustard to taste. Now, pour this into a bowl and then brush it over your king crab meat. Grill the meat over high heat and then let it grill for a few minutes. When it's finished, brush the marinade over the meat once more and then serve with your favorite sides.
