I have a soft spot for any sandwich that drips down your wrists a little, and this Spicy Korean BBQ Chicken Sandwich does exactly that—in the best possible way. Every time I make it, I end up doing that little happy bounce you do when food just hits. It’s spicy, sweet, crunchy, messy, and borderline addictive. And honestly? I think you’re going to feel the same way once you take your first bite.

Let me give you a quick heads-up on what we’re making here. This is a juicy, Korean-inspired chicken sandwich loaded with gochujang heat, a sticky BBQ glaze, and a fresh, tangy slaw that cuts through the richness like a dream. It’s the kind of sandwich you make when you want comfort food with personality—bold flavors, big textures, and serious weeknight energy.

What makes this sandwich special is the combo of warm heat and cold crunch. The chicken comes off the pan caramelized and glossy, while the slaw wakes everything up with brightness. And since you’re building it yourself, you can lean into the spice or dial it back—your call.

Tools You’ll Need

Just a few basics, and each one is doing real work:

• Skillet or grill pan: this gives the chicken that caramelized finish.
• Mixing bowls (2): one for marinating the chicken, one for tossing the slaw.
• Whisk: to blend the sauce so it’s smooth and glossy.
• Tongs: to flip the chicken without losing all that saucy goodness.
• Cutting board and knife: for prepping the slaw ingredients.
• Measuring cups/spoons: so the sauce hits the right balance.

Ingredients

Serves 4

For the Chicken

• 1 ½ lb (680 g) boneless skinless chicken thighs
• 3 tbsp (45 g) gochujang
• 2 tbsp (30 ml) soy sauce
• 2 tbsp (30 ml) rice vinegar
• 2 tbsp (30 g) brown sugar
• 1 tbsp (15 ml) sesame oil
• 3 cloves garlic, minced
• 1 tsp (5 g) grated ginger
• 1 tbsp (15 ml) neutral oil for cooking

For the Tangy Slaw

• 2 cups (140 g) shredded cabbage
• 1 cup (65 g) shredded carrots
• 2 green onions, thinly sliced
• 3 tbsp (45 ml) rice vinegar
• 1 tbsp (15 g) sugar
• 1 tbsp (15 ml) mayo (optional but lovely)
• Salt and pepper to taste

To Assemble

• 4 brioche or potato buns
• 1 tbsp (15 g) butter for toasting
• Sesame seeds (optional)
• Pickles (optional but 10/10 recommended)

Step-by-Step Instructions

1. Make the Marinade

Whisk the gochujang, soy sauce, rice vinegar, brown sugar, sesame oil, garlic, and ginger. You want it smooth and glossy. If it tastes a little intense, that’s perfect—it mellows as it cooks.

2. Marinate the Chicken

Drop the chicken thighs into the bowl and coat them well. If you can, let them sit for 30 minutes. If you’re in a rush, even 10 minutes helps. I’ve definitely done the “marinate while the pan heats” move and it still works.

3. Prep the Slaw

In another bowl, toss cabbage, carrots, and green onions. Whisk vinegar, sugar, and mayo separately, then drizzle it over. Give it a toss. The slaw should taste bright and sharp—you’ll see how good it feels next to the spicy chicken.

4. Cook the Chicken

Heat oil in a skillet over medium-high. Add the chicken thighs and let them sear. Don’t fuss with them too much—you want that caramelized edge. Flip once they release naturally. Cook until glossy and slightly sticky.

5. Toast the Buns

Swipe butter on each bun and toast them face-down until golden. This step is small but changes everything.

6. Build the Sandwich

Layer chicken onto the buns, pile on the slaw, sprinkle sesame seeds, and add pickles if you like drama (I do). Press the top bun down gently—this is when you realize you’ve made something incredible.

Variations and Customization

If you’re the kind of person who likes to tweak, here’s your playground:

• Swap chicken thighs for breasts if you prefer leaner meat.
• Use a gluten-free tamari instead of soy sauce.
• Add thin-sliced cucumber for extra crunch.
• Throw in a slice of melty cheese for a fusion vibe.
• Make it extra spicy with a drizzle of sriracha or more gochujang.

Serving Ideas

This sandwich is a star on its own, but you could make it a full moment:

• Serve with sweet potato fries.
• Add kimchi on the side.
• Pair with a simple cucumber salad.
• Serve with roasted corn or a quick slaw.

Make-Ahead and Storage

• Cooked chicken keeps in the fridge for 3 days.
• Slaw lasts 24 hours (after that, it softens but still tastes good).
• Reheat chicken in a skillet over medium so it stays juicy.
• You can prep the marinade 3 days in advance.

Pro Tips and Mistakes to Avoid

Just between us:

• Don’t skip the bun toasting—it keeps everything from getting soggy.
• Marinate longer if you want deeper flavor, but not overnight (gochujang can overpower).
• Let the chicken rest for 3–5 minutes before slicing to keep juices in.
• If your slaw tastes flat, add a pinch more sugar or vinegar—it’s all about balance.
