This soy-marinated flank steak is my son's favorite. I usually slice it thinly and serve it with twice-baked potatoes and a green salad to round out the meal. Leftovers are great for French dip sandwiches. &mdash Gayle Bucknam of Greenbank, Washington


  • 1/4 cup soy sauce
  • 2 tablespoons water
  • 3 garlic cloves, thinly sliced
  • 1 tablespoon brown sugar
  • 1 tablespoon canola oil
  • 1/2 teaspoon ground ginger
  • 1/2 teaspoon pepper
  • 1 beef flank steak (1 pound)


  1. In a shallow dish, combine the first seven ingredients; add steak and turn to coat. Cover and refrigerate for 8 hours or overnight, turning occasionally.
  2. Drain steak, discarding marinade. Grill, covered, over medium-hot heat for 6-8 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°).

Tender Flank Steak Tips

What is the best soy sauce to use for marinating this flank steak?

When used as a marinade, soy sauce tenderizes and flavors meat. The salt in any soy sauce will tenderize flank steak, so choose the sauce you think tastes best. Dark soy sauce (also known as Koikuchi) is the most common and offers a well-rounded flavor. Light soy sauce (or Usukuchi) has a lighter color but should be used sparingly due to its intense flavor.

For some, tamari sauce is a gluten-free alternative (but be sure to check the ingredient list). It can be used interchangeably with soy sauce, but it does have a distinctly rich flavor. Not sure if tamari is right for you? Our Test Kitchen pros compared tamari versus soy.
