The main difference is that bulgogi itself is marinated thin-sliced rib-eye steak, while bibimbap is a bowl of vegetables and beef that is topped with a fried egg and spicy sauce. Like bibimbap, bulgogi is typically served with vegetables over rice for a flavorful and savory meal. The thinly sliced meat is marinated in a mix of soy sauce, sesame oil, garlic, and sugar for at least an hour before cooking. This marinade gives it a distinct sweet and savory flavor that is hard to replicate with other dishes.
