MARINADE FOR FLAT IRON STEAK RECIPES

Steps:

• Prepare the following, adding each to a zip-top gallon bag as you complete it: Pick the leaves from 2 fresh rosemary sprigs until you have 2 teaspoons and coarsely chop, smash and peel 2 garlic cloves, trim and cut 2 medium scallions into 1-inch lengths.
• Add 2 tablespoons olive oil, 1 tablespoon balsamic vinegar, 1 tablespoon soy sauce, 1 teaspoon Dijon mustard, 3/4 teaspoon kosher salt, 1/2 teaspoon black pepper, 1/2 teaspoon smoked paprika, and 1/2 teaspoon ground coriander, and stir to combine. Add 1 flat iron steak, press to remove any air, and seal the bag. Massage the steak to coat in the marinade. Place on a plate and refrigerate for at least 4 hours and up to overnight.
• Remove the steak from the marinade and pat dry with paper towels. Heat 2 tablespoons neutral cooking oil in a large skillet over medium-high heat until shimmering. Add the steak and cook, rotating the pan 90° halfway through, until a golden-brown crust forms on the bottom, 4 to 5 minutes total. Flip the steak and repeat browning the second side.
• Reduce the heat to medium. Flip the steak and continue to cook, flipping every 1 to 2 minutes, until the thickest part of the steak registers 125°F to 130°F for medium rare, 4 to 6 minutes more (for a total cooking time of 12 to 15 minutes from when the steak first went into the pan). Transfer the steak to a clean cutting board and let rest for 5 minutes. Slice across the grain to serve.

Steps:

• Remove packaging and pat meat dry with paper towels. Line a plate with paper towels, place meat on top and set aside to dry further and come to cool room temperature (30 to 60 minutes, depending on the weather). Turn occasionally; replace paper towels as needed.
• Place a heavy skillet, preferably cast-iron, on the stove and sprinkle lightly but evenly with about 1/4 to 1/2 teaspoon salt. Turn heat to high under pan. Pat both sides of steak dry again.
• When pan is smoking hot, 5 to 8 minutes, pat steak dry again and place in pan. (If using two steaks, cook in two batches.)
• Let steak sizzle for 1 minute, then use tongs to flip it over, moving raw side of steak around in pan so both sides are salted. Press down gently to ensure even contact between steak and pan. Keep cooking over very high heat, flipping steak every 30 seconds. After it’s been turned a few times, sprinkle in two pinches salt. If using pepper, add it now.
• When steak has contracted in size and developed a dark-brown crust, about 4 minutes total, check for doneness. To the touch, meat should feel softly springy but not squishy. If using an instant-read thermometer, insert into side of steak. For medium-rare meat, 120 to 125 degrees is ideal: Steak will continue cooking after being removed from heat.
• Remove steak to a cutting board and tent lightly with foil. Let rest 5 minutes.
• Serve in pieces or thickly slice on the diagonal, cutting away from your body and with the top edge of the knife leaning toward your body. If cooking skirt or hanger steak, make sure to slice across the grain of the meat.
