Ingredients

Instructions

  1. Step 1: In a bowl, mix 1/4 cup soy sauce, 2 tablespoons brown sugar, 1 tablespoon smoked paprika, 2 tablespoons olive oil, 1 teaspoon garlic powder, and 1/2 teaspoon black pepper until the sugar dissolves and the mixture is smooth.
  2. Step 2: Place 1.25 pounds flat iron steak in a shallow dish and pour the marinade over it, turning to coat evenly. Cover and refrigerate for at least 3 hours or overnight for deep flavor.
  3. Step 3: Preheat grill to medium-high heat (around 425°F). Remove the steak from the marinade, shaking off excess, and discard the marinade.
  4. Step 4: Grill the steak for 5 minutes per side, turning once, until a caramelized crust forms and the internal temperature reads 135°F for medium-rare.
  5. Step 5: Let the steak rest for 7 minutes on a cutting board before slicing thinly across the grain to maximize tenderness.
