Ingredients

  • 1/2 cup dry red wine*
  • 1/2 cup soy sauce*
  • 2 tablespoons light brown sugar
  • 2 teaspoons sesame oil
  • 3 cloves garlic, smashed and peeled
  • 1/4 teaspoon ground black pepper
  • 1 1/2 pounds flank steak

Instructions

  1. In a medium bowl, whisk together the red wine, soy sauce, brown sugar, sesame oil, garlic, and pepper. Place steak in a gallon size zip-top bag and pour in the marinade. Press all of the air out of the bag and seal tightly. Shake the bag and work the marinade around to ensure all surfaces of the meat are covered. Refrigerate for 12-24 hours (24 is preferable), turning the bag once if you can remember!

  2. When you're ready to grill, remove the steak from the fridge 15-20 minutes or so ahead of time to get the chill off of it (this allows it to cook more evenly.) Preheat your grill or indoor grill pan to medium-high. Once preheated, shake the excess marinade off of the steak and grill for 4-5 minutes per side (for medium/rare-medium), depending on the thickness of your steak and your desired temperature. Let the steak rest for 5-10 minutes before slicing. Be sure to slice it against the grain on an angle. Serve immediately!

Recipe Notes

*I like to use a full bodied, dry red wine for this recipe. Something like a Garnacha or Spanish red is what I typically use, but just be sure you use something that you'd enjoy drinking - the flavor only intensifies when you cook with it!
*Don't use low-sodium soy sauce for this recipe. The meat really needs regular soy sauce to be seasoned properly.
*If you have the time, marinate this steak for 24 hours. The longer, the better. If you can't, 12 hours is totally fine!
