Steak and Marinade Ingredients:

  • 1-1/2 pounds flank steak
  • ¼ cup soy sauce
  • ½ cup dry red wine
  • 2 green onions, chopped
  • ¼ cup fresh lemon juice
  • ¼ cup canola oil
  • 2 tablespoons Worcestershire sauce
  • 3 cloves garlic, minced
  • 2 tablespoons Dijon mustard

Sorrel Sauce Ingredients:

  • 2 tablespoons unsalted butter
  • 2 green onions, finely minced
  • ¾ cup dry white wine
  • 1 cup chicken stock
  • 2 cups whipping cream
  • ½ cup finely chopped fresh sorrel leaves *
  • Finely ground pepper to taste


  1. Prepare the marinade and marinate the flank steak

Place the flank steak in a large, sealable plastic bag or a shallow glass dish. In a separate bowl, combine the soy sauce, red wine, green onions, lemon juice, canola oil, Worcestershire sauce, and garlic. Pour the mixture over the steak, making sure it’s well-coated. Seal the bag or cover the dish with plastic wrap and refrigerate for at least 8 hours or overnight, turning occasionally to ensure even marination.

  1. Prepare the sorrel sauce

Before grilling the steak, start preparing the sorrel sauce. In a heavy saucepan on the stove or barbecue, melt the butter and cook the minced green onions until fragrant. Add the white wine and bring to a boil, then cook for about 5 minutes or until the liquid is reduced to around 3 tablespoons. Stir in the chicken stock and continue boiling until it’s reduced to about ½ cup. Add the whipping cream and chopped sorrel leaves to the sauce, and season with pepper to taste. Keep the sauce warm over low heat while you barbecue the steak.

  1. Grill the marinated flank steak

Remove the steak from the marinade and coat both sides with Dijon mustard. Grill the steak on medium-high heat for 6 to 8 minutes on each side, depending on your desired level of doneness.

  1. Slice and serve the steak

Once the steak is cooked to your liking, let it rest for a few minutes before slicing it against the grain into 1/2-inch-thick strips. Serve the steak with the sorrel sauce on the side for guests to spoon over their portions.

About Sorrel


Sorrel is a perennial herb that is commonly used in French cooking and can be easily grown in North American herb gardens. Its slightly sour taste, reminiscent of wild strawberries, adds a unique flavor profile to dishes. Sorrel can be washed and torn into bite-sized pieces to be added to salads, or pureed into hot or cold soups.

If sorrel is not available, you can substitute it with spinach and add ½ teaspoon of fresh lemon juice to mimic its sour flavor. Arugula, which has a peppery taste, can also be used as a substitute.
