Grilled Thick-Cut Porterhouse Steaks

Ingredients

2 (2 ½- to 3-pound) porterhouse steaks, 2 inches thick, fat trimmed to ¼ inchKosher salt and pepper 4 teaspoons olive oil (if using gas)3 tablespoons unsalted butter, melted

Before You Begin

Flare-ups may occur when grilling over charcoal. If the flames become constant, slide the steaks to the cooler side of the grill until the flames die down.

Instructions

  1. Pat steaks dry with paper towels and sprinkle each side of each steak with 1 teaspoon salt. Transfer steaks to large plate and refrigerate, uncovered, for at least 1 hour or up to 24 hours.
  2. FOR A CHARCOAL GRILL: Open bottom vent completely. Light large chimney starter filled with charcoal briquettes (6 quarts). When top coals are partially covered with ash, pour evenly over half of grill. Set cooking grate in place, cover, and open lid vent completely. Heat grill until hot, about 5 minutes.FOR A GAS GRILL: Turn all burners to high, cover, and heat grill until hot, about 15 minutes. Leave primary burner on high and turn off other burner(s). (Adjust primary burner [or, if using three-burner grill, primary burner and second burner] as needed to maintain grill temperature of 450 degrees.)
  3. Pat steaks dry with paper towels. If using gas, brush each side of each steak with 1 teaspoon oil. Sprinkle each side of each steak with ½ teaspoon pepper.
  4. Clean and oil cooking grate. Place steaks on hotter side of grill, with tenderloins facing cooler side. Cook (covered if using gas) until evenly charred on first side, 6 to 8 minutes. Flip steaks and position so tenderloins are still facing cooler side of grill. Continue to cook (covered if using gas) until evenly charred on second side, 6 to 8 minutes longer.
  5. Flip steaks and transfer to cooler side of grill, with bone side facing fire. Cover and cook until thermometer inserted 3 inches from tip of strip side of steak registers 115 to 120 degrees (for medium-rare), 8 to 12 minutes, flipping halfway through cooking. Transfer steaks to wire rack set in rimmed baking sheet, tent with aluminum foil, and let rest for 10 minutes.
  6. Stir 1/4 teaspoon salt into melted butter. Transfer steaks to carving board. Carve strips and tenderloins from bones. Place bones on platter. Slice steaks thin against grain, then reassemble sliced steaks around bones. Drizzle with melted butter and season with salt and pepper to taste. Serve.

Why This Recipe Works

We take the intimidation out of grilling thick-cut porterhouse steaks with this dependable method. Setting up a half-grill fire with a cooler side and a hotter side allowed us to control the amount of crusty exterior and achieve rosy interiors for these steaks. We grilled the steaks directly over the coals to char them before moving them to the cooler side of the grill to finish cooking. To protect the leaner, quicker-cooking tenderloin portion of the porterhouse, we positioned the steaks with the tenderloins facing the cooler side of the grill. The T-shaped bone in the middle of the steaks acts as a heat shield, further protecting the tenderloins from the heat. Last but certainly not least, we took the steaks’ temperatures at the area near the tapered tip of the strip portion to get the most accurate reading. A drizzle of melted butter was a simple way to add flourish to our steaks.
