Ingredients You’ll Need

For the Korean BBQ Glaze

• ¼ cup gochujang (Korean chili paste) – The signature ingredient that provides spicy, savory depth.
• 3 tablespoons low-sodium soy sauce – Adds rich umami flavor.
• 3 tablespoons packed brown sugar – Balances the heat while creating a sticky glaze.
• 1 tablespoon rice vinegar – Brightens and balances the sauce.
• 2 teaspoons toasted sesame oil – Adds a rich nutty aroma.
• 2 cloves garlic, minced – Enhances the savory flavor.
• 1 teaspoon freshly grated ginger – Adds warmth and freshness.
• 1 teaspoon cornstarch – Thickens the glaze into a glossy coating.
• 1 tablespoon water – Combines with the cornstarch to form a smooth slurry.

For the Chicken

• 4 thick boneless, skinless chicken thighs (about 1½ pounds) – Stay juicy and flavorful during grilling.
• 1 tablespoon vegetable oil – Prevents sticking and encourages browning.
• ½ teaspoon kosher salt – Enhances the natural flavor of the chicken.
• ¼ teaspoon black pepper – Adds mild seasoning.

For the Creamy Slaw

• ½ cup mayonnaise – Creates a rich, creamy dressing.
• 1 tablespoon rice vinegar – Adds brightness to balance the richness.
• 1 teaspoon sugar – Softens the acidity and rounds out the flavor.
• 1½ cups shredded green cabbage – Adds fresh crunch.
• 1½ cups shredded purple cabbage – Provides vibrant color and crisp texture.
• 1 large carrot, julienned – Adds natural sweetness and crunch.

For Assembly

• 4 brioche buns – Soft, buttery buns that perfectly complement the bold flavors.
• 2 tablespoons melted unsalted butter – Used for toasting the buns.
• Toasted white sesame seeds – Adds nutty flavor and visual appeal.
• 2 green scallions, finely chopped – Fresh garnish that brightens every bite.

Step-by-Step Instructions

Step 1: Prepare the Creamy Slaw

In a large bowl, whisk together the mayonnaise, rice vinegar, and sugar until smooth. Add the shredded green cabbage, purple cabbage, and carrots, tossing until evenly coated. Refrigerate while preparing the remaining ingredients.

Step 2: Make the Korean BBQ Glaze

Combine the gochujang, soy sauce, brown sugar, rice vinegar, sesame oil, garlic, and ginger in a small saucepan. Bring to a gentle simmer over medium heat. Whisk together the cornstarch and water, then stir the slurry into the sauce. Cook for 2–3 minutes, stirring constantly until thick, glossy, and smooth.

Step 3: Grill the Chicken

Preheat a grill or grill pan to medium-high heat. Brush the chicken thighs with vegetable oil and season with salt and pepper. Grill for 5–7 minutes per side, or until the internal temperature reaches 165°F (74°C). During the final 2 minutes, generously brush both sides with the Korean BBQ glaze.

Step 4: Rest the Chicken

Transfer the grilled chicken to a plate and allow it to rest for 5 minutes. Brush with an additional layer of glaze before assembling the sandwiches to maximize flavor.

Step 5: Toast the Brioche Buns

Brush the cut sides of the brioche buns with melted butter. Toast them on the grill or in a skillet for 1–2 minutes, until golden brown and lightly crisp.

Step 6: Assemble the Sandwiches

Place a glazed chicken thigh on each toasted bottom bun. Top generously with the creamy slaw, then sprinkle with toasted sesame seeds and chopped scallions. Finish with the top bun and serve immediately while warm.

Recipe Notes & Tips

• Rest the Chicken – Letting the chicken rest keeps it juicy and prevents moisture loss.
• Toast the Buns – Toasting adds flavor while preventing the buns from becoming soggy.
• Adjust the Heat – Reduce the gochujang for a milder sandwich or add extra for more spice.
• Don’t Overcook the Chicken – Use a meat thermometer to ensure perfectly juicy chicken.
• Prepare the Slaw Ahead – The flavors improve after chilling for 15–30 minutes.
• Brush on Extra Glaze – A final coating before serving creates maximum flavor and shine.
