Test Kitchen - Soy Marinated Flank Steak

Today's recipe was really easy to make gluten free, all it took was swapping out the soy sauce for tamari (gluten free soy sauce).  The flavor was really good, almost beef jerky-like, and I broiled it instead of grilling it. I served it with white rice and roasted corn. Delish!

Ingredients

• 1 cup tamari or soy sauce
• 1/4 cup packed light-brown sugar
• 3 tablespoons cider vinegar
• 1 tablespoon Worcestershire sauce
• 2 teaspoons Dijon mustard
• 1 teaspoon red-pepper flakes
• 1/4 teaspoon ground pepper
• 1 flank steak (about 1-2 pounds)
• 2 tablespoons olive oil

Directions 

• In a 9-by-13-inch baking dish, whisk together soy sauce, sugar, vinegar, Worcestershire, mustard, red-pepper flakes, and pepper. Place steak in dish and cover dish tightly with plastic wrap. Swirl dish so that marinade coats the top of steak. Refrigerate 1 hour - overnight, turning steak occasionally. 
• Turn on broiler. Pour excess marinade into a saucepan. Then place steak 2-3 inches away from heat. Broil for 10-15 minutes, turning steak halfway through.
• Meanwhile, simmer excess marinade over medium-high heat until reduced by half, about 10 minutes. 
• Let meat rest 5 minutes, then cut across the grain at a slight diagonal to serve.
