Ingredients

Meat Ingredients:

  • 3 pound Flank Steak

Marinade Ingredients:

  • 1/2 cup Soy Sauce
  • 1/4 cup Sugar brown sugar or granulated
  • 2 tbsp Mirin
  • 1/4 cup Pineapple juice
  • 4 cloves Garlic minced
  • 1 tbsp Fresh ginger grated
  • 1 tbsp Gochujaru
  • 1 tbsp Sesame oil
  • 1/2 tsp Black pepper
  • 3 Scallions sliced thin

Serving Ingredients:

  • Butter lettuce leaves
  • steamed rice
  • extra scallions
  • Gochujang

Instructions

  • Prep the Steak: Trim the flank steak of any excess fat or silver skin. If desired, lightly score the surface in a diamond pattern to help the marinade penetrate.
  • Mix & Marinate: Combine all marinade ingredients in a bowl. Place the steak in a food-safe container or gallon bag, add the sliced scallions, and pour the marinade over the meat.
  • Chill: Cover and refrigerate for 4 hours.
  • Temper: Remove the steak from the fridge 20–30 minutes before grilling to take the chill off.
  • BGE Setup: Prepare your Big Green Egg for direct grilling (no convEGGtor). Stabilize the temperature between 450°F and 500°F.
  • The Cook: Place the steak on the grate. Close the dome and cook for 4 minutes. Flip the steak and cook for another 3–4 minutes.
  • The Pull: Remove the steak when the internal temperature hits 130°F – 135°F for medium-rare.
  • Rest & Slice: Let the meat rest for 10 minutes. Slice thinly against the grain at a 45-degree angle.
  • Serve: Arrange on a platter and serve with lettuce cups and an ice-cold Cass.
