gallon-sized resealable bag or large glass bowl with lid
Ingredients
1 1/2-2poundsflank steak
½cupvegetable oil
⅓cupsoy sauce(low sodium if you prefer)
2tablespoonsfresh lemon juice
¼cupred wine vinegar
1 ½tablespoonsWorcestershire sauce
½teaspoonblack pepper
2tablespoonsbrown sugar
1tablespoonDijon mustard
1tablespoonred pepper flakes
3clovesgarlic, minced
Instructions
Whisk all of the marinade ingredients together. Place 2/3 to 3/4 of the marinade into a resealable gallon plastic bag (or use a covered dish). Reserve the remaining marinade to pour over the cooked steak.
Add the flank steak to the bag. Squeeze out the air and seal. Shake to coat the meat well. Place it in the refrigerator for 6 hours or overnight. Occasionally, flip the bag so the marinade distributes evenly over the meat.
Remove the flank steak from the refrigerator 30 minutes to 1 hour before you plan to grill it. Remove the steak from the bag and pour the marinade into a small bowl for basting the meat during grilling.
Heat the grill to 375-400°F. Place the steak on the grill and cook each side for 5 minutes, basting as you go. Then check the temperature with a meat thermometer and use these ranges for the degree of doneness you would like:* Rare--120-125°F* Medium-rare--130°F* Medium--145°FIf the meat has not reached the desired temperature for the doneness you want, flip it and cook it for 1-2 more minutes. Recheck the temperature. Continue cooking until the desired doneness is achieved. Then, remove it from the grill and let it rest for 5 minutes. Cut it across the grain into thin slices. Pour the reserved marinade (discard the basting marinade) over the top of the sliced steak.
