Grilled Flank Steak with Homemade Marinade




The flank steak is located behind the rib cage, beneath the loin and in front of the rear legs. It’s a boneless and very thin piece of muscle. This makes it a particularly well-suited cut for marinating and a quick sear on the Otto Grill. The cut tastes best when cooked medium rare, otherwise, it will become tough and flavorless. Otto chose a soy-lemon marinade because the sweet and sour taste compliments the rich, meaty flavor of the flank steak.





Enjoy the original, Otto-approved, perfectly grilled flank steak recipe with a simple homemade soy sauce marinade.

  1. Steak marinade with soy sauce and garlic

    Crush the garlic clove and mix it with all the other ingredients for the marinade in a shallow bowl. Voila: a simple steak marinade with soy sauce. For more tips check out: how to marinate meat.

  2. Marinate the meat

    Put the Flank steak on a plate and prick it slightly with a fork. Drizzle the homemade steak marinade over the meat until it is fully covered. Cover the bowl with plastic wrap and let the flank steak rest in the refrigerator at least 4 hours.



  1. Preheat the Otto Grill to 1500°F for three minutes. Place the Flank steak on the grill grate and set it on Meat-O-Meter stage 2. Grill it for about 1 minute on each side.

  2. Cooking level of the flank steakt

    Set burners to medium temperature, set the Meat-O-Meter on stage 5 and allow the grilled flank steak to finish cooking for about 3-5 minutes in the lower part of the Otto Grill Then it should be medium rare and thus super juicy and tender.
