Bulgogi is a popular Korean dish made from marinated beef, typically sliced thinly. The marinade usually consists of soy sauce, sugar, sesame oil, garlic, and pepper, which gives the meat a sweet and savory flavor. It is often grilled or stir-fried, making it tender and juicy. This dish is commonly served with rice and various side dishes known as banchan. Bulgogi can also be made with other proteins, such as chicken or pork, and is enjoyed in many Korean households and restaurants around the world.
