Flank Steak Bulgogi

Korean beef bulgogi can be made with any good quality cut of meat. Flank steak is full of beefy flavor, but somewhat tough, but this marinade with some juice from a can of pineapple quickly tenderizes the flank steak.

I’m in NYC for a few days visiting my children! Before I left home on Saturday, I prepared some foods to bring to them, including this bulgogi made with flank steak. I quickly cut up 2 flank steaks, in a pack from Costco, and prepared this marinade that works really well with flank steak. While I was doing all that, it occurred to me that I should also share this recipe I’ve been enjoying for quite some time.

The classic bulgogi is typically made with thinly cut ribeye, but it can certainly be made with any good quality cut of meat. I find flank steak works really well! Typically, flank steak is grilled whole and then sliced to be served. I also have a recipe here where I cooked the whole flank steak and then sliced to serve for my slow cooker bulgogi. For regular bulgogi, the meat is sliced before being marinated. Flank steak is full of beefy flavor, but somewhat tough, so it’s important to cut against the grain.

How to tenderize flank steak for bulgogi

This marinade with some juice from a can of pineapple does the nice trick tenderizing the flank steak. You can substitute it with Korean green plum extract (maesilcheong, 매실청) or grated Korean pear. I cooked some for our lunch within an hour of marinating, and the meat was tender but pleasantly chewy. It will be best to marinate up to a half day, but you can marinate longer if you like your meat very tender.

If you have made my all purpose marinade, you will simply need to add the pineapple juice, ginger, and sesame oil to 1 cup of the all purpose marinade to make a similar marinade as this one.
