Best Mustard Herb Flank Steak Recipes

MUSTARD-MARINATED FLANK STEAK

Steps:

• Place the steak flat in a large nonreactive dish such as glass or porcelain. Using the tip of a sharp knife, lightly score the top of the steak diagonally in a large crisscross pattern to make what looks like 1-inch diamonds across the steak. This allows the marinade to penetrate into the meat.
• In a 2-cup measuring cup, whisk together the wine, olive oil, mustard, 1 teaspoon salt, and 1/2 teaspoon pepper. Stir in the shallots and garlic. Pour the marinade over and under the steak until it's completely coated. Scatter the tarragon on top. Cover the dish with plastic wrap and allow it to marinate in the refrigerator for at least 2 hours but preferably overnight.
• Half an hour before serving, remove the steak from the refrigerator and heat a charcoal grill with a layer of hot coals. (You can also set a gas grill on medium-high heat.) Sprinkle the steak with 1 teaspoon salt and 1 teaspoon pepper. Discard the remaining marinade.
• Grill the steak for about 5 minutes per side for medium-rare. Place the steak on a clean plate, cover tightly with aluminum foil, and allow to rest for 10 minutes. Slice the steak thin, cutting diagonally across the grain. Sprinkle with salt and serve hot.

EDDIE JACKSON'S FLANK STEAK

Steps:

• To make the marinade, combine the oil, vinegar, garlic, mustard, oregano, parsley, rosemary, Worcestershire and some salt and pepper in a food processor and pulse until the garlic and herbs are incorporated in the oil.
• Place the steaks in a ziptop bag, pour the marinade over the steaks and marinate at least 30 minutes and up to overnight.
• Before grilling, remove the steaks from the bag and pour the remaining marinade into a small pan. Bring the marinade to a boil, lower to a simmer and cook for 2 to 3 minutes. Use this sauce to drizzle on the steaks as soon as you remove them from the grill.
• Prepare a gas or charcoal grill for high heat. When up to temperature, grease the grates with a little oil, then place the steaks over the hottest part of the grill. Depending on the thickness of the steaks and the temperature of the grill, the steaks should grill about 3 minutes per side for medium rare (flank steak is best served medium rare). Remove the steaks from the grill, drizzle with the sauce and let them rest for 5 to 7 minutes.

FLANK STEAK WITH LEMON-LIME HERB SAUCE

Steps:

• Remove the flank steak from the refrigerator 30 minutes prior to cooking to bring it to room temperature.
• In a medium bowl, add the scallions, chives, olive oil, basil, parsley, lemon zest, lemon juice, lime zest, lime juice, mustard, red pepper flakes and 1/2 teaspoon kosher salt. Stir to combine and set aside.
• Heat a grill pan over medium-high heat. Drizzle a small amount of olive oil onto one side of the steak and use a silicone brush to spread it all over the steak. Sprinkle with a nice pinch of kosher salt and pepper. Transfer the meat to the grill pan, seasoning side down. Drizzle the other side of the steak with a small amount of olive oil and once again brush it to cover and sprinkle with salt and pepper. For medium-rare, cook the steak until the internal temperature is 135 degrees F, 4 to 5 minutes per side. Remove the steak to a plate and let it rest for 10 minutes before slicing.
• Slice the steak against the grain. Add the slices to a platter and spoon on the lemon-lime herb sauce. Serve extra sauce on the side.
