RECIPE FOR FLAT IRON STEAKS 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:

• Preheat the oven to 400 degrees.
• Heat a large cast-iron skillet over high heat for 5 to 7 minutes.
• Meanwhile, pat dry the filets mignons with paper towels. Brush the filets lightly all over with the oil. Combine the fleur de sel and cracked pepper on a plate and roll the filets on all sides in the mixture, pressing lightly to help the salt and pepper adhere. The steaks should be evenly coated with the salt and pepper.
• When the pan is extremely hot, add the steaks and sear evenly on all sides (top, bottom, and sides) for about 2 minutes per side. (Be sure the cooking area is well ventilated.) You'll probably need about 3 turns to sear the sides and about 10 minutes total.
• Remove the pan from the heat and arrange all the filets flat in the pan. Top each with a tablespoon of butter, then place the pan in the oven. Cook the filets for 8 to 12 minutes to 120 degrees for rare and 125 degrees for medium-rare. Remove the steaks to a platter, cover tightly with aluminum foil, and allow to rest for 5 to 10 minutes.
