Ingredients & Substitutions
Building this visually stunning and flavor-packed sandwich requires a mix of fresh produce, hearty proteins, and essential pantry staples. Here is exactly what you need to bring this culinary blueprint to life.
Boneless Skinless Chicken Thighs: You will need 4 thick thighs, roughly 1.5 lbs (680g) total. Chicken thighs retain their moisture perfectly at high heat, allowing for a deep char without drying out.
Brioche Buns: Grab 4 high-quality brioche buns. Their high butter content yields a beautiful golden-brown crust when toasted, providing a sturdy, mildly sweet base.
Green and Red Cabbage: Use 1 cup (70g) of finely shredded green cabbage and 1 cup (70g) of finely shredded red cabbage. This dual-color blend adds immense visual appeal and a robust, crispy texture to the slaw.
Julienned Carrots: Add 1/2 cup (55g) of freshly julienned carrots. They introduce a natural sweetness and an extra layer of firm crunch to the creamy slaw.
Mayonnaise: Use 1/4 cup (60g) of full-fat mayonnaise for the creamy coleslaw dressing. This provides a rich, cooling fat that neutralizes the spicy gochujang glaze.
Rice Vinegar & Sugar: You need 1 tbsp (15ml) of rice vinegar and 1 tsp (4g) of white sugar. These invisible foundations give the slaw dressing its necessary tangy and sweet balance.
Gochujang Paste: Measure out 3 tbsp (45g) of gochujang (Korean chili paste). This fermented staple is the spicy, umami-rich soul of our glossy BBQ sauce.
Soy Sauce & Brown Sugar: Combine 1/4 cup (60ml) of soy sauce with 3 tbsp (37g) of brown sugar. As they simmer, they reduce and caramelize, creating that signature thick, dark reddish-brown glaze.
Aromatics (Garlic & Ginger): Mince 2 cloves of fresh garlic and grate 1 tsp (2g) of fresh ginger. Cooking these into the sauce adds a zesty, aromatic bite that cuts through the sweetness.
Sesame Oil: Just 1 tbsp (15ml) of toasted sesame oil stirred into the sauce adds a deep, nutty finish to the chicken glaze.
White Toasted Sesame Seeds: Reserve 1 tbsp (9g) of white toasted sesame seeds for garnishing. They add a delicate crunch and a beautiful visual contrast against the dark BBQ sauce.
Green Scallions: Slice 2 fresh scallions very thinly. The bright green color pops beautifully on the final dish while offering a sharp, fresh onion flavor.
Cooking Oil, Butter, Salt, & Pepper: You need 2 tbsp (30ml) of neutral cooking oil for searing, 2 tbsp (28g) of butter for toasting the buns, and 1 tsp (5g) each of Kosher salt and black pepper to properly season the raw chicken.
Equipment Needed
- Large Cast Iron Skillet: Essential for maintaining the high heat required to achieve a beautiful char on the chicken thighs.
- Small Saucepan: Needed to gently simmer and reduce the Korean BBQ sauce until it reaches a thick, glossy consistency.
- Mixing Bowls: One medium bowl for tossing the fresh slaw and a small bowl for whisking the creamy dressing.
- Sharp Chef’s Knife: Crucial for finely shredding the cabbage and thinly slicing the delicate scallions without bruising them.
Step-by-Step Instructions
1. Prepare the Creamy Slaw
In a small mixing bowl, vigorously whisk together the mayonnaise, rice vinegar, white sugar, and a pinch of salt and pepper. Whisk until the dressing is completely smooth and bright white.
In a separate medium bowl, combine the finely shredded green cabbage, shredded red cabbage, and julienned carrots. Pour the creamy white dressing over the vegetables and toss until lightly and evenly coated.
Place the slaw in the refrigerator to chill. Letting it rest allows the flavors to meld while ensuring the cabbage remains perfectly crispy for building the sandwich later.
2. Simmer the Glossy BBQ Sauce
Place a small saucepan over medium-low heat. Add the gochujang, soy sauce, brown sugar, minced garlic, grated ginger, and sesame oil.
Whisk the ingredients constantly as the brown sugar dissolves and the mixture begins to bubble. Allow the sauce to simmer for 3 to 5 minutes.
Watch carefully for a visual change: the sauce will reduce and transform into a thick, glossy, dark reddish-brown glaze. Once it lightly coats the back of a spoon, remove it from the heat and set aside.
3. Sear and Char the Chicken
Pat the boneless, skinless chicken thighs completely dry with a paper towel. This ensures a proper crust. Season both sides generously with the kosher salt and black pepper.
Heat the neutral cooking oil in a large cast-iron skillet over medium-high heat. Wait until the oil is shimmering and just beginning to smoke before carefully adding the chicken.
Cook undisturbed for 5 to 6 minutes per side. You are looking for a deep, dark golden-brown crust and slightly blackened, charred edges. The internal temperature must reach 165°F (74°C).
4. Glaze the Chicken and Toast the Buns
Once the chicken thighs are fully cooked and beautifully charred, turn the heat to low. Pour the thickened Korean BBQ sauce directly over the chicken in the skillet.
Toss the thick thighs continuously for 1 to 2 minutes. The heat will cause the sugars to caramelize further, heavily glazing the chicken in a sticky, glossy coating.
In a separate skillet over medium heat, melt the butter. Place the brioche bun halves facedown in the melted butter and toast for 1 to 2 minutes until the bottoms are a lightly toasted, golden-brown. Remove from the heat.
5. Assemble and Garnish
Place the golden-brown bottom brioche bun on a white ceramic serving plate. Pile a generous bed of the chilled, creamy slaw onto the bottom bun.
Using tongs, carefully rest one thick, juicy, heavily glazed chicken thigh directly on top of the crispy slaw. Sprinkle the sticky surface of the chicken with the white toasted sesame seeds.
Follow up with a garnish of the thinly sliced bright green scallions. Finally, take the top half of the toasted brioche bun and rest it slightly askew on top of the chicken to reveal the colorful, mouth-watering layers underneath.
Expert Tips for Success
- Dry the Chicken: Always pat your chicken thighs completely dry before searing. Excess surface moisture creates steam, which prevents that signature dark, savory char from forming.
- Do Not Over-Dress the Slaw: Coat the shredded cabbage and carrots lightly. If the slaw is swimming in creamy dressing, it will make the bottom brioche bun soggy and ruin the crunch.
- Watch the Sugar: The brown sugar in the Korean BBQ sauce can burn quickly. Once you add the sauce to the skillet to glaze the chicken, keep the heat on low and keep the chicken moving.
- Perfect the Toast: Toasting the brioche buns in butter isn’t just for flavor; it creates a fat barrier. This golden-brown crust prevents the juices from the slaw and chicken from destroying the bun.
- Slice Scallions Thinly: Thickly chopped green onions can overpower a bite. Slicing them paper-thin ensures they distribute evenly, adding just the right pop of bright flavor to the glossy dark sauce.
Storage & Reheating
If you have leftover components, it is crucial to store them separately to maintain their ideal textures. Store the cooled, glazed chicken in an airtight container in the refrigerator for up to 3 days. Keep the slaw in a separate container; note that it will lose some crunch by the second day.
Store brioche buns at room temperature in a sealed bag. To reheat, microwave the chicken for 1 minute, or preferably, warm it in a skillet over low heat with a splash of water until heated through. Assemble the sandwich fresh with cold slaw and freshly toasted buns.

Frequently Asked Questions
Yes. The heat comes primarily from the gochujang paste. To reduce the spiciness, you can halve the amount of gochujang and add a little extra soy sauce and brown sugar to maintain the volume and deep flavor.
You can shred the cabbage and julienne the carrots in advance, but to keep the slaw perfectly crispy, avoid mixing the vegetables with the creamy dressing until 15 to 30 minutes before serving.
Absolutely! To save prep time, you can swap the fresh cabbage and carrots for a pre-shredded coleslaw mix. Just toss it with the homemade creamy mayonnaise and rice vinegar dressing.
Ensure your chicken thighs are patted completely dry before cooking. Use a cast-iron skillet over medium-high heat with a neutral oil, and let the chicken sear undisturbed for 5-6 minutes per side before adding the sugary glaze.
Boneless, skinless chicken thighs are highly recommended. Their higher fat content allows them to stay incredibly juicy even when seared at high temperatures to achieve a smoky char.
