Marinated Flank Steak

by Nanny Bubby

This recipe of mine is so very old. It came from a friend in Scottsdale and it is my go-to recipe when I entertain. The key is freezing this for two days. I have no idea why, but it works! In fact, for my best friends 40th birthday in St. Louis, I prepared a marinated frozen flank steak from Costco. It was huge. I froze it for two days, and then I carried it on the plane in my carry on for 3.5 hours from Las Vegas to St. Louis. When we arrived at her home, I slipped it into her refrigerator. The next afternoon we prepared the most beautiful birthday dinner for her and the marinated steak was a huge hit! I told the story over a bottle of wine, about how I carried that meat in a carry-on, frozen all the way from Las Vegas. We laughed for days.

Total Time:

35 minutes




  • 3 to 5 lbs. flank steak
  • 2 Tbsp. sugar
  • ½ tsp. ground ginger
  • 2 Tbsp. white vinegar
  • 2/3 c. soy sauce
  • ½ tsp. garlic powder


  • Place the meat into a Ziploc bag.
  • Mix the ingredients above in a bowl with a whisk and pour into the bag.
  • Massage the meat with the marinade and let sit at room temperature for about 30 minutes.
  • Place the meat in the bag and evenly surround it with the marinade. Then, lay it flat into the freezer.
  • After about two hours, before it is fully frozen and just icy, flip the meat over. Keep frozen for at least two days.
  • Thaw overnight in the refrigerator and take it out to thoroughly defrost on the counter for about one hour the next morning.
