In a large mixing bowl, gently combine 1 ½ pounds of ground beef with 2 pressed cloves of garlic, ½ teaspoon of grated ginger, 1 teaspoon of sesame oil, 1 teaspoon of soy sauce, and ¼ teaspoon of black pepper. Use your hands to mix gently.

Shape the mixture into four patties, each weighing around 6 ounces. Create a small dent in the center of each patty to prevent puffing.

Preheat a cast-iron skillet over medium-high heat for about 5 minutes. Sear the patties for 3 to 4 minutes on each side until a golden-brown crust forms.

While the patties rest, warm the Korean BBQ sauce in a small saucepan and coat each burger patty with the sauce.

Toast the brioche hamburger buns until golden brown. Spread a layer of chili garlic mayo on the bottom half, followed by the glazed patty and a generous scoop of kimchi slaw. Place the top bun on and press lightly.
