Flatiron steaks are a great option for a casual dinner or a special occasion. They are tender, relatively lean, and can be cooked on the grill or in a skillet. Their strong flavor pairs well with bold sauces, such as the mustard, caper, and herb sauce in this recipe.
Ingredients:
2 tablespoons of grainy mustard
2 tablespoons of extra-virgin olive oil, plus more as needed
2 tablespoons of capers in brine, drained and chopped
1 tablespoon of red wine vinegar
2 teaspoons of packed light brown sugar
1 teaspoon of Worcestershire sauce
1 small clove of garlic, finely grated
2 tablespoons of chopped fresh parsley
2 tablespoons of finely chopped fresh chives
4 flat-iron steaks (about 230gms each)
Directions:
Preheat a grill to medium-high heat.
In a large bowl, combine the mustard, olive oil, capers, vinegar, 1 teaspoon of brown sugar, Worcestershire sauce, and garlic. Stir everything together.
Add the parsley, chives, and 2 tablespoons of water to the bowl. Season with salt and pepper. Set the caper sauce aside.
Lightly coat the steaks with olive oil.
In a separate bowl, mix together 2 teaspoons of salt, 1 teaspoon of pepper, and the remaining 1 teaspoon of brown sugar. Rub this mixture onto both sides of the steaks.
Oil the grill grates.
Grill the steaks for 3 to 5 minutes on each side, depending on their thickness, for medium-rare doneness.
Remove the steaks from the grill and let them rest on a cutting board for 5 to 10 minutes.
Slice the steaks against the grain and top them with some of the caper sauce. Serve the remaining caper sauce on the side.
