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 like chicken or pork, but beef remains the traditional choice. It is enjoyed both at home and in restaurants, making it a staple of Korean cuisine.
