Marinated Flank Steak

By · Print This Post Print This Post

IMG_4448xWe just had a dinner party where we served this marinated flank steak. Flank steak is a great meat to prepare for small dinner parties. It is not the cheapest meat to serve, but it is reasonable and the sliced meat will serve several people. It takes little time to prepare and cook, has little fat, no bones, and slices easily. Most importantly, the resulting steak slices are always flavorful and very tender. We always get compliments when we make it, so I thought I would share our marinade recipe. This marinade recipe is good for a flank steak 1.5 to 2 lbs.

Flank Steak and Marinade Recipe


1/2 tsp ground ginger
1/2 tsp ground mustard (dry powder)
1-1/2 tsp molasses (or sugar)
1/4 Cup soy sauce (gluten-free options include San-J Tamari Soy Sauce, Eden Foods Organic Tamari Soy Sauce, and La Choy regular soy sauce)
1/4 Cup olive oil
3 cloves garlic, minced


  1. Combine all the ingredients in a small bowl and stir thoroughly.
  2. If the steak is small enough, put it in a zip-style bag and pour the marinade on top. Massage the marinade into the meat and let it sit in the refrigerator for 4-6 hours or overnight. If the steak is too large for a bag, put it into a large shallow dish (like a 9 x 13 pan) and cover tightly with plastic wrap. Flip the steak at least once while it’s marinating.
  3. Remove the steak from the marinade and place on a medium-high to hot grill. (Discard the remaining marinade.) Grill the steak for about 8 minutes on each side to cook the steak to medium or medium-rare.
  4. Once you remove the steak from the grill, cover it with foil and let it sit for 5 – 10 minutes. Then, slice the steak against the grain, at an angle.

Additional Notes:

  • One flank steak (1.5 – 2 lbs.) will serve about 6 – 8 people.
  • My kids love this steak, too! It is very tender and easy for little ones to chew.
  • It makes great meat for sandwiches or to top salads, hot or cold.
  • I have marinated the steak for as little as 2 hours and still have had it turn out very good.
  • I also use this marinade for beef stir fry and Chinese chicken (for salads, rice dishes, stir fry, etc.). It really gives the meat good flavor.
  • If you are going to use a zip-style bag, you can always just mix the marinade ingredients in the bag before putting the meat in. Just saves cleaning another bowl.

I’m not that comfortable with cuts of beef to know what is best to serve company so I usually go with other options. I will give this a try for the family first, then maybe I can add it to my list of company worthy recipes. Thanks for linking up.

I love a good flank steak. It’s so easy to make a London Broil-type dish using this cut of meat and a good marinade. Yours looks and sounds terrific, Heather! I love molasses as an ingredient. Great tips on how to use your grilled flank steak, too. I love eating London Broil cold for breakfast. ūüôā
