1. 1
   Thaw the frozen sirloin steak in the refrigerator until softened, then slice it very thinly.
2. 2
   Mince the six garlic cloves and place them in a bowl.
3. 3
   Add one-quarter cup gochugaru, one-quarter cup rice syrup, and one-quarter cup gochujang to the garlic.
4. 4
   Add one-half cup water, two tablespoons soy sauce, and one-half teaspoon ground black pepper to the mixture and stir well to combine.
5. 5
   Place the sliced beef into the sauce and mix to coat evenly. Marinating layer by layer is not necessary.
6. 6
   The beef can be cooked immediately or refrigerated for a few hours or overnight before cooking.
7. 7
   Heat a pan with oil and cook the sliced king oyster mushroom until fragrant.
8. 8
   Add the chopped green onions and cook until aromatic and slightly crispy.
9. 9
   Add the marinated beef to the pan and reduce heat to medium. Cook until the beef is done.
10. 10
    Transfer the cooked beef and vegetables to a serving plate, leaving the sauce residue in the pan for later use.
11. 11
    Serve the bulgogi alongside lettuce, green chili peppers, fresh garlic, and ssamjang (Korean dipping sauce) for wrapping and eating.
12. 12
    Use the leftover sauce in the pan with rice and kimchi to make stir-fried rice (bokkeumbap) as a follow-up dish.
