Prep the Steaks: About 1 hour (or more) before grilling, whisk together the dry rub ingredients. Pat the steaks dry with a paper towel and then sprinkle the rub generously on both sides of the steaks and rub it into the meat. Cover and chill until about 20-30 minutes before ready to grill.
When you are ready to grill, preheat the grill to medium-high heat (about 450°F-500°F) and remove the steaks from the refrigerator to allow them to come to room temperature for about 20 minutes.
Prepare The Gorgonzola Sauce*: Just before you grill the steaks, in a small sauce pan, over medium-low heat, melt the butter. Add the garlic and heat for about 1 minute until fragrant, stirring frequently. Add the heavy cream and stir to combine. Simmer for about 5 minutes, bubbling very lightly. It will reduce a bit, and that is ok!
Shift heat to low and add in the gorgonzola, parmesan, dijon mustard, salt and pepper (if desired, to taste). Whisk continuously to melt the cheese. When sauce is smooth and begins to thicken, remove from heat and stir in chopped parsley. Set aside and cover to keep warm.
Grill the Steaks: When grill is preheated, clean and oil to prep. Add the steaks over direct heat and grill for about 5-6 minutes with grill closed. Flip the steaks and cook for another 4-7 minutes until desired doneness is achieved. If the steaks don't easily pull away from the grill, they are not ready to be flipped.
Suggested cook times:Medium-Rare (135°F): 4-5 minutes per side Medium (145°F): 5-6 minutes per side Medium-Well (155°F): 6-8 minutes per side Well-Done (165°F): 7-9 minutes on each side When the steaks reach about 5°F UNDER the desired doneness temperature, remove them from the grill. Allow to rest for about 5 minutes.
Serve with a nice spoonful of the gorgonzola sauce and top with fresh parsley and chives. Enjoy!
