Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Boneless skinless chicken thighs
Chicken thighs are ideal because they stay juicy and flavorful when grilled or pan-seared. They absorb the marinade beautifully and develop a rich caramelized exterior.

Gochujang
This Korean chili paste provides the signature heat and depth. It delivers a balanced combination of spice, sweetness, and umami.

Soy sauce
Soy sauce enhances the savory notes of the marinade and complements the sweetness of the barbecue glaze.

Honey
Honey adds natural sweetness and helps create that glossy, sticky finish when the chicken cooks.

Garlic
Fresh minced garlic infuses the marinade with bold aroma and savory warmth.

Fresh ginger
Ginger brings brightness and subtle heat that lifts the overall flavor profile.

Sesame oil
A small amount of sesame oil adds nutty depth and authentic Korean-inspired character.

Rice vinegar
Rice vinegar adds a gentle tang that balances the sweetness of the sauce and brightens the slaw.

Green cabbage
Thinly shredded cabbage forms the base of the crispy slaw, providing crunch and freshness.

Carrots
Julienned carrots add color, subtle sweetness, and extra texture to the slaw.

Mayonnaise
Mayonnaise creates a creamy base for the slaw dressing and helps coat the vegetables evenly.

Sandwich buns
Soft brioche or burger buns provide structure while complementing the bold filling.

Salt and black pepper
Essential for seasoning both the chicken and the slaw.

Directions

Begin by preparing the marinade. In a bowl, whisk together gochujang, soy sauce, honey, minced garlic, grated ginger, sesame oil, and rice vinegar. Add the chicken thighs and coat them thoroughly. Allow the chicken to marinate for at least 30 minutes, or up to overnight for deeper flavor.

While the chicken marinates, prepare the crispy slaw. In a large bowl, combine shredded cabbage and carrots. In a separate small bowl, mix mayonnaise, a splash of rice vinegar, salt, and black pepper. Toss the dressing with the vegetables until evenly coated. Refrigerate until ready to assemble.

Heat a grill pan or skillet over medium-high heat. Remove the chicken from the marinade and cook for about 5–6 minutes per side, or until fully cooked and caramelized. During the final minute, brush additional marinade onto the chicken to intensify the glaze.

Toast the sandwich buns lightly until golden. Slice the cooked chicken if desired, then place it onto the bottom half of each bun. Top generously with crispy slaw and close with the top bun. Serve immediately while warm and fresh.

Servings and timing

This recipe makes 4 sandwiches.
Preparation time: 20 minutes
Marinating time: 30 minutes
Cooking time: 15 minutes
Total time: Approximately 1 hour and 5 minutes

Storage/reheating

Store leftover chicken separately from the slaw in airtight containers in the refrigerator for up to 3 days. Reheat the chicken gently in a skillet over medium heat. Assemble the sandwich just before serving to maintain the slaw’s crisp texture.

Variations and Customizations

This sandwich can be easily customized to suit your preferences. For extra heat, add a pinch of red pepper flakes or a drizzle of sriracha to the marinade. If you prefer a milder version, reduce the amount of gochujang and increase the honey slightly.

For a lighter alternative, substitute Greek yogurt for part of the mayonnaise in the slaw dressing. I once replaced half of the mayonnaise with yogurt, and it created a pleasantly tangy, lighter texture while still maintaining creaminess.

If you enjoy additional crunch, add thinly sliced red onions or toasted sesame seeds to the slaw. Pickled cucumbers also make a refreshing topping that complements the spicy chicken beautifully.

For a grilled outdoor version, cook the marinated chicken over charcoal for a smoky flavor that enhances the barbecue profile. You can also transform this sandwich into lettuce wraps for a lower-carbohydrate option.

Finally, try using chicken breasts if preferred, though be careful not to overcook them to preserve tenderness.
