Bulgogi is one of Korea’s most popular beef dishes that is made from thinly sliced sirloin or another prime cut of beef (rib eye). It is usually marinated in a mixture of soy sauce, sesame oil, black pepper, garlic, onions, ginger, and sugar for two to four hours to enhance the flavor and its tenderization. Bulgogi is traditionally grilled but broiling or pan-cooking is common as well.
Whole cloves of garlic, sliced onions, and chopped green peppers are often grilled or cooked at the same time. It is often served to non-Koreans as a first taste of Korean cuisine.
