In a mixing bowl, whisk together ¼ cup of soy sauce, 2 tablespoons of brown sugar, 2 minced garlic cloves, 1 teaspoon of freshly grated ginger, 1 tablespoon of sesame oil, and a pinch of black pepper.

Add 1 pound of ground beef and 2 finely chopped green onions to the marinade. Mix gently to combine, then let it marinate in the refrigerator for at least 15 minutes.

Remove the marinated beef from the fridge and divide it into four portions, shaping each into a patty with a slight indentation in the center.

In a separate bowl, whisk together ½ cup of mayonnaise, 2 tablespoons of gochujang, 1 tablespoon of lime juice, and 1 teaspoon of honey. Refrigerate the sauce.

Cook the patties on a preheated skillet or grill for 4–5 minutes per side until browned and cooked through.

Toast the burger buns in a separate skillet for about 1-2 minutes until golden brown.

Spread the creamy gochujang mayo on the bottom half of each bun, then top with a beef patty, greens, and cucumber or pickled radish.

Sprinkle sesame seeds on top of each assembled burger and serve immediately.
