Make marinade. Combine all ingredients for the marinade in a zip-top bag or a non-reactive glass bowl.
½ cup olive oil, ¼ cup red wine vinegar, ¼ cup honey, 2 Tablespoons Worcestershire sauce, 1 ½ teaspoons black pepper, 1 ½ teaspoons Kosher salt, 1 teaspoon red pepper flakes, 5 sprigs fresh thyme leaves, 5 cloves garlic
Marinate steaks. Place the steak in the marinade, and massage or toss the steak to ensure it is evenly coated on all sides. Place the bag or container of marinating steak in the refrigerator and allow the steak to marinate for 4-8 hours. Smaller steaks can marinate for 4 hours, thicker cuts can marinate for 6-8 hours.
4 Delmonico steaks
Sear steaks. Preheat your grill to medium-high heat (around 450 degrees F) for two-zone cooking (one high heat side, one side with little to no heat). Remove your steaks from the bag and carefully shake off any excess marinade or large pieces of herbs. Place the steaks on the high-heat side of the grill and cook for 3-4 minutes per side, leaving the lid open.
Finish grilling. Once both sides have a nice sear, move the steaks to the low-heat side of the grill, close the lid, and cook to your desired doneness. The time on this step varies by your desired doneness, but a medium rare steak should reach temperature in about 6-8 minutes.
Rest and serve. Remove the steaks to a cutting board and allow them to rest for 5-10 minutes before serving.
