Korean sweet spicy beef, often known as "bulgogi" or "gochujang beef," is a popular Korean dish featuring thinly sliced beef marinated in a flavorful blend of sweet and spicy ingredients. The marinade typically includes gochujang (Korean red chili paste), soy sauce, brown sugar, garlic, and sesame oil, giving the beef a perfect balance of heat and sweetness. The beef is then grilled or stir-fried until tender and caramelized. It's commonly served with rice and garnished with scallions and sesame seeds, making it a delicious and vibrant meal.
