Place the seasoned steaks on the hot grill and cook for 2-3 minutes per side until they reach an internal temperature of 120°F for medium-rare. Remove from grill and let rest for a few minutes.

Place a cast iron skillet on the grill. Add butter and flour, stirring constantly for 1-2 minutes until they form a paste. Mix in the cowboy butter rub seasoning.

Slowly whisk in about three-quarters of the milk in small batches, stirring constantly to prevent lumps. Let the mixture thicken between each addition.

Stir in the Dijon mustard, then gradually add all the shredded cheeses, stirring until completely melted and smooth. Thin with remaining milk as needed to get the perfect consistency.

Transfer the skillet to a 400°F oven and bake for 10 minutes until you get a beautiful golden crust on top. Garnish with fresh chopped parsley and serve immediately.
