Grill-Smoked Herb-Rubbed Flat-Iron Steaks

Ingredients

2 teaspoons dried thyme 1 teaspoon dried rosemary ¾ teaspoon fennel seeds ½ teaspoon black peppercorns ¼ teaspoon red pepper flakes 4 (6- to 8-ounce) flat-iron steaks, ¾ to 1 inch thick, trimmed1 tablespoon kosher salt 1—1 ½ cups (2 ½-3 ¾ ounces) wood chips Vegetable oil spray 2 lemons, quartered lengthwise

Before You Begin

This recipe requires rubbing the steaks with salt and letting them sit at room temperature for 1 hour before cooking. You can substitute blade steaks for the flat-iron steaks, if desired. We like both cuts cooked to medium (130 to 135 degrees). We like hickory chips in this recipe, but other kinds of wood chips will work. Gas grills are not as efficient at smoking meat as charcoal grills, so we recommend using 1 1/2 cups of wood chips if using a gas grill.

Instructions

  1. Grind thyme, rosemary, fennel seeds, peppercorns, and pepper flakes in spice grinder or with mortar and pestle until coarsely ground. Transfer to small bowl. Pat steaks dry with paper towels. Rub steaks evenly on both sides with salt and place on wire rack set in rimmed baking sheet. Let stand at room temperature for 1 hour. (After 30 minutes, prepare grill.)
  2. Using large piece of heavy-duty aluminum foil, wrap wood chips (1 cup if using charcoal; 1 1/2 cups if using gas) in 8 by 4 1/2-inch foil packet. (Make sure chips do not poke holes in sides or bottom of packet.) Cut 2 evenly spaced 2-inch slits in top of packet.
  3. 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. Place wood chip packet on coals. Set cooking grate in place, cover, and open lid vent completely. Heat grill until hot and wood chips are smoking, about 5 minutes.FOR A GAS GRILL: Remove cooking grate and place wood chip packet directly on primary burner. Set grate in place, turn all burners to high, cover, and heat grill until hot and wood chips are smoking, about 15 minutes. Leave primary burner on high and turn other burner(s) to medium.
  4. Clean and oil cooking grate. Sprinkle half of herb rub evenly over 1 side of steaks and press to adhere. Lightly spray herb-rubbed side of steaks with oil spray, about 3 seconds. Flip steaks and repeat process of sprinkling and pressing steaks with remaining herb rub and coating with oil spray on second side.
  5. Place lemons and steaks on hotter side of grill, cover (position lid vent over steaks if using charcoal), and cook until lemons and steaks are well browned on both sides and meat registers 130 to 135 degrees (for medium), 4 to 6 minutes per side. (If steaks are fully charred before reaching desired temperature, move to cooler side of grill, cover, and continue to cook.) Transfer lemons and steaks to clean wire rack set in rimmed baking sheet, tent with foil, and let rest for 10 minutes. Slice steaks thin against grain and serve, passing lemons separately.

Why This Recipe Works

Smoking steaks can lend them complexity, but most recipes overwhelm the meat’s delicate flavor with too much smoke. We found that the key was using a small amount of wood chips and cooking the steaks quickly over direct heat so that they were just kissed with smoke. Since wood chips pack differently, we weighed the chips for more control over the smoke quantity. Salting the steaks for an hour before cooking ensured that the seasoning penetrated below the meat’s surface, and coating them with an herb-spice rub lent an extra layer of flavor that complemented the smoke. We also grilled lemons to serve with the steaks for a hit of brightness.
