My grilled marinated Soy Rosemary Garlic flank steak is perfect for tacos sandwiches nachos and more! Marinated soy rosemary flank Make sure you give it a full 24 hours in the fridge to make the best flavored flank steak!!
Place flank steak into a 1 gallon self-sealing plastic bag. Mix remaining ingredients together and pour marinade over flank steak. Seal bag, removing as much air as possible. Marinate overnight in fridge, turning bag over a couple of times to ensure even distribution of the marinade. When ready to cook, start the Traeger according to grill instructions. Set the temperature to 450 degrees F and preheat, lid closed, for 10 to 15 minutes. Remove flank steak from marinade. Discard remaining marinade. Grill flank steak to rare or medium-rare 120 F to 130 F. Remove from grill and let rest for 10 minutes. Cut flank steak across grain. Sprinkle slices with additional Traeger prime rib rub before serving.
