I have gotten to that point in the summer where when I’m planning my menu for the week, I’m only looking for recipes that take very little prep time and very little energy.
Enter the easy marinated flank steak recipe. I have been a total flank steak lover lately. Not only is it a cheaper cut of steak, but I love that I can buy just one steak to feed the whole family. And it’s a versatile cut, as well.
If you love the flavors of Korean barbecue, you will definitely love this Korean Flank Steak recipe. It only takes minutes to prepare the marinade, then you let it marinate and do it’s thing. And then no heating up the kitchen as you grill this baby. (Although you could use a grill pan if you don’t have an outdoor grill.)
This flank steak was gobbled right up at our dinner table. There wasn’t a scrap left. I think that tells you how much we loved it!! A perfect grilling recipe for the summer!
Ingredients
- Soy Sauce: I like to use reduced sodium soy sauce so that it’s not too salty.
- Brown Sugar: This just adds a little bit of sweetness.
- Sesame Oil: You want to use toasted sesame oil for added flavor.
- Ginger: Fresh ginger is best here, and will give your steak the best flavor.
- Flank Steak: This recipe calls for 1 1/2 pounds of flank steak, but don’t worry if yours is a little bigger or a little smaller. Most flank steaks are between 1-2 pounds, so anything in that range will work. Of course, the bigger the flank steak, the bigger the portions, so you may get more than 4 servings out of your steak.
How to Make Korean Flank Steak
STEP 1: Combine all of the marinade ingredients in a ziplock bag. Add the steak, and shake it around a little bit to cover the steak with the marinade. Refrigerate for 6-24 hours, turning the steak over a time or two as it marinates.
STEP 2: Let the steak come to room temperature while your grill preheats. Grill over medium heat until the steak is to your desired doneness, about 10-12 minutes for medium-rare. You’ll want to turn it just once while it’s grilling. Let the steak sit for a few minutes before slicing to serve.
Tips and Tricks
- If you are marinating a shorter amount of time, you can score the top of the steak so that the flavors permeate easier, but I usually find that I don’t need to do this.
- I like to marinate the steak on the longer side, but you don’t want to marinate it for over 24 hours, as the meat will start to get a weird texture as it breaks down.
- The best way to test for doneness is with an instant read thermometer. Remember that the temperature will increase a couple degrees with carryover cooking.
- Cut the steak across the grain to serve. This way you will have tender pieces instead of tough steak.

It is a big deal, when the child goes off to kindergarten. As I look back on it, I had the exact same feeling as when that same child got a driver’s license and drove of down the road without me. So yes, it is the ending of an era—-enjoy it. Just as I will enjoy this recipe for flank steak. I pinned it.

My husband and I are just like you and can’t get enough flank steak! Versatile, easy and affordable! I don’t normally score my steak before marinating and I’m not sure why. I’ll have to try that the next time and see how much more flavor it holds onto! Your pics are amazing too! Making my mouth water this early in the morning!
