Perfectly seared, juicy flank steak cooked hot and fast on a Blackstone griddle, with a simple soy-Worcestershire marinade and a foolproof method for tender, restaurant-quality results every time.

Ingredients 

Ingredients

  • 1 to 1.5 lbs flank steak
  • Kosher salt and freshly ground black pepper, to taste
  • 2 tablespoons high-heat oil, avocado, canola, or vegetable, for the griddle

Marinade (recommended):

  • 1/3 cup soy sauce
  • 1/4 cup olive oil
  • 2 tablespoons Worcestershire sauce
  • 3 cloves garlic, minced
  • 1 tablespoon brown sugar or honey
  • 1 lime, juiced
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon black pepper

For serving (optional):

  • Chopped fresh parsley or cilantro
  • Lime or lemon wedges
  • Sautéed onions, peppers, or mushrooms

Instructions

  • Marinate: Whisk all marinade ingredients together. Add the steak to a zip-top bag, coat well, and refrigerate 30 minutes to 8 hours.
  • Prep: Remove steak from marinade and pat completely dry. Let sit at room temperature 20 to 30 minutes.
  • Preheat: Heat the Blackstone to medium-high (400 to 450°F) for 10 to 15 minutes.
  • Oil & season: Spread a thin layer of high-heat oil on the steel. Season the steak with salt and pepper.
  • Sear: Place the steak down and leave undisturbed for 3 to 4 minutes until a deep crust forms.
  • Flip: Using tongs, flip once and sear the other side 3 to 4 minutes.
  • Check temp: Pull at 130 to 135°F for medium-rare (recommended).
  • Rest: Tent loosely with foil and rest 5 to 10 minutes.
  • Slice: Cut thinly against the grain at a slight angle. Garnish and serve.
