1 tablespoon sugar ; you can use any type - I use brown sugar
2 tablespoons water
You can also use fruit juice as well, in which case, reduce the amount of sugar you add. I find the additional liquid helps to marinate the meat better. Traditionally, pureed Asian pear is used and if you have time, you can use this!
5 - 6 cloves of garlic (finely minced) ; I use a garlic press
1 medium onion (around 100g), thinly sliced
1/2 teaspoon black pepper
Dash of powdered ginger
Handful of chopped green onions
Sesame seeds
Sesame oil
[Optional] Sliced carrots or other vegetables
You can use any type of beef. Most Asian / Korean supermarkets will sell pre-sliced beef that you can use. I generally prefer beef that is less fatty. I cut the beef into slices around 2 inch by 2 inch (roughly), but adjust the size to your liking.
Instructions
Combine the soy sauce, sugar, water, garlic, black pepper, and powdered ginger in a bowl. Mix well.
Add the sliced onions and beef to the bowl and mix with the sauce. Marinate in the fridge for at least 3 hours (overnight is better).
Before frying, take the beef out of the fridge and let it rest at room temperature for around 5 - 10 minutes.
Preheat a pan over medium-high heat and add a bit of oil. If your beef is fatty, use less oil.
Add the Bulgogi mixture and fry until cooked (around 4 - 7 minutes depending on thickness of beef).
Turn off the heat, and add green onions, sesame oil, and sesame seeds and toss using the residual heat.
