Balsamic-Marinated Flank Steak

Dominic Perri for TOPS Club, Inc.

Crusty, yet tender, slices of beef are cloaked in a balsamic marinade and tossed with a tangle of grilled scallions and peppers. Flank steak is relatively inexpensive and lean—it’s traditionally served in slices. When you cut it, be sure to slice “against the grain.” Look at the cut of meat: You’ll see muscle fibers running in one direction. When the steak is cooked, you will cut thin slices against the muscle fibers. This guarantees tender slices of steak.

Prep and cook time: 25 min. Servings: 2 (3 oz. steak and ¼ c. peppers and scallions per person)

Gluten Free


  • ¼ c. balsamic vinegar
  • 2 t. reduced-sodium, gluten- free tamari*
  • 2 t. canola oil
  • 2 t. honey
  • 2 cloves garlic, minced
  • 6 oz. flank steak
  • 2 med. red bell peppers, cut in half through the stem end, with cores and tops removed
  • bunch scallions

*Most brands of tamari (aged soy sauce) are certified gluten-free, but it doesn’t hurt to check. If you, or someone you are serving, has a gluten intolerance, check the ingredients first to ensure that your bottle is gluten-free.


  1. Prepare your grill. While it gets started, mix the vinegar, tamari, oil, honey and garlic in a medium bowl. Drop the steak into the bowl, swirling it around to cover it in the marinade. Add the peppers and scallions to the bowl and cover them in the marinade as well.
  2. When the grill is ready, lay the steak, peppers and scallions separately on the grill. Discard any remaining marinade.
  3. Cook the steak for about 4 min. per side for medium doneness. Remove the steak and let the peppers and scallions keep cooking. Let the steak rest for 5 min. Remove the vegetables from the grill. Cut the peppers into thin strips. Slice the steak, against the grain, into ¼-in. slices. Serve the steak with the peppers and scallions.
