Okay folks, this is
@igorsMistress ' fault. She started talking about bulgogi tacos and I started reminiscing and of course now Debby want's me to post a bulgogi recipe here.

So here goes... Full disclosure, it's been a long time since I've made it and I mixed up recipes and techniques to get as close as I could to what I got on the streets of Korea. First it is my belief that Bulgogi is to Korea what BBQ is to the states. It can be way different Seoul than it was in Kunsan. Also different from restaurant to street vendor. So I've kind of lifted bits from all and come up with what I like. I'll present three recipes below... I've lifted some ingredients from the third and added them to the second. I've always used flank steak, but if you can afford ribeye, go for it.
The First recipe is the simplest has a 4.8 rating with 1.1K reviews. Can't go wrong with it.

The second is closest to what I remember, but is lacking Ginger, rice wine and red pepper flake.

The third has the rice wine and ginger, so I likely just stole those amounts and added them to the second. The gochujang was important for flavor (and I use it liberally)...

Regardless of street vendor or restaurant, the universal cooking vessel was a cast iron wok or skillet. Generally prepared at the table or while you watched. The chef would add sesame seed, green onion, fresh ginger and red pepper flake to the meat in the wok. I have had it with sliced onion, and it didn't make it better. I've never had it with carrot, but imagine it would add color and sweetness.
Always served with fresh lettuce leaves to wrap it in, bean/pepper paste, rice and a variety of fermented veg. pickled daikon radish, a carrot slaw of sorts, pickled cucumbers and of course kimchee. Some places also added a hot chili oil as a condiment. Oh and fresh sliced garlic for extra heat. Enjoy...
