Korean BBQ Chicken Sandwich – Sweet, Spicy & Irresistible

I’ve been making this Korean BBQ chicken sandwich for weeknight dinners and weekend cookouts alike — it’s sticky, sweet, a touch spicy, and topped with a crunchy cabbage slaw that keeps every bite bright. This recipe uses juicy boneless chicken thighs (or breasts if you prefer), a gochujang-forward marinade, and a quick mayo-based slaw that balances the bold sauce. If you like bold sandwich flavors, you might also enjoy the chipotle grilled chicken with avocado sandwich from the same collection.

Why you’ll love this Korean BBQ Chicken Sandwich with Cabbage Slaw recipe

This sandwich hits the sweet-heat-umami trifecta: soy and brown sugar bring caramelized depth, honey and sesame oil add roundness, and gochujang gives a fermented chili complexity you don’t get from plain hot sauce. It’s fast to prep (marinate, toss the slaw, cook), budget-friendly when using thighs, and kid-friendly if you tone down the gochujang. Make it for a weeknight dinner, a backyard lunch, or when you want a restaurant-worthy sandwich at home.

“The sauce clings to the chicken and the slaw keeps it from getting heavy — an instant family favorite.” — home cook review

How this recipe comes together

This is a simple, three-part process:

• Marinate the chicken for flavor and moisture.
• Toss together a quick cabbage slaw to provide crunch and acidity.
• Pan-sear or grill the chicken until caramelized, toast the buns, and assemble.

You’ll need about 10–15 minutes active hands-on time plus at least 30 minutes for the chicken to soak up the marinade (longer is better). Expect about 25–30 minutes cooking time depending on your heat source.

What you’ll need

• 2 lbs boneless skinless chicken thighs (substitute breasts, but thighs stay juicier)
• 1/2 cup soy sauce (low-sodium recommended)
• 3 tablespoons brown sugar
• 1 tablespoon honey
• 2 tablespoons gochujang (Korean fermented red chili paste) — reduce to 1 tbsp for milder heat
• 1 tablespoon rice vinegar
• 1 tablespoon sesame oil
• 4 garlic cloves, minced
• 1 teaspoon grated fresh ginger
• 1 tablespoon toasted sesame seeds
• 2 green onions, thinly sliced

Cabbage slaw:

• 3 cups shredded green cabbage
• 1 cup shredded red cabbage
• 1 medium carrot, julienned or shredded
• 2 tablespoons mayonnaise
• 1 tablespoon rice vinegar
• 1 teaspoon sugar
• Salt and black pepper to taste

To finish:

• 4 brioche or potato sandwich buns
• Butter for toasting buns

Notes: You can swap tamari for soy sauce for a wheat-free option. Use Greek yogurt in the slaw instead of mayo to lighten it.

Step-by-step instructions

1. Make the marinade: Whisk together soy sauce, brown sugar, honey, gochujang, rice vinegar, sesame oil, garlic, and grated ginger until sugar dissolves.
2. Marinate the chicken: Place chicken thighs in a zip-top bag or shallow dish. Pour half the marinade over the chicken (reserve the other half for basting/sauce). Refrigerate at least 30 minutes, ideally 2–4 hours. If overnight, bring to fridge-safe procedures and discard any marinade that’s touched raw chicken unless you boil it for 2–3 minutes first.
3. Prepare the slaw: In a bowl, whisk mayonnaise, rice vinegar, sugar, salt, and pepper. Toss with both cabbages and carrot. Chill until assembly.
4. Heat your pan or grill: Preheat a skillet over medium-high (or grill to medium-high). Add a little oil to the pan if using a skillet.
5. Cook the chicken: Sear chicken thighs 4–6 minutes per side until caramelized and internal temperature reaches 165°F (74°C). Baste with reserved marinade in the last 1–2 minutes and let it reduce slightly in the pan to glaze the meat.
6. Rest and slice: Transfer chicken to a cutting board and rest 5 minutes, then slice thinly against the grain.
7. Toast the buns: Butter the cut sides and toast in the skillet or under a broiler until golden.
8. Assemble: Spread a little slaw on the bottom bun, pile on sliced chicken, sprinkle toasted sesame seeds and green onions, top with more slaw if you like, and close.

Timing tip: If short on time, marinate at least 30 minutes; flavor improves substantially after 1–2 hours.

Best ways to enjoy it

Serve this sandwich with a crisp side so the meal isn’t too heavy. Try:

• French fries or sweet potato fries for classic comfort.
• A bright cucumber salad or pickled radishes to cut richness.
• For a meal swap, these BBQ chicken roasted sweet potato bowls are a hearty side or alternate way to use leftover Korean BBQ chicken.

For plating: stack the chicken and slaw slightly off-center so each bite gets sauce and crunch. Add extra lime wedges for a citrus lift.

Storage and reheating tips

• Refrigerator: Store leftover cooked chicken and slaw separately in airtight containers for up to 3–4 days. Keep buns separate to avoid sogginess.
• Freezing: Cooked chicken freezes well for up to 3 months. Cool completely, wrap tightly, and thaw overnight in the fridge before reheating.
• Reheating: Reheat chicken gently in a 325°F (160°C) oven until warm (about 10–12 minutes) or in a covered skillet over low heat with a splash of water to prevent drying. Avoid microwaving for long periods — it can toughen the meat.
• Food safety: Always discard any marinade that’s been in contact with raw chicken unless boiled for at least 2–3 minutes.

Pro chef tips

• Use thighs for juiciness: Thighs tolerate higher heat and longer cooking without drying.
• Dry the chicken before searing: Patting it dry helps create a better caramelized crust.
• Reduce reserved marinade into a glaze by simmering for 2–3 minutes — this concentrates flavor and ensures it’s safe if it touched raw chicken.
• Slice across the grain for tender bites.
• Make the slaw a few hours ahead: it mellows slightly and the flavors meld, but toss just before serving to keep it crunchy.

Recipe variations

• Spicy-sweet: Add 1 tablespoon gochugaru (Korean chili flakes) with the gochujang for extra heat and texture.
• Vegetarian swap: Marinate and grill thick portobello caps or tofu steaks; press tofu first and double the marinade amount.
• Sandwich build: Swap brioche for a toasted hoagie roll or lettuce wrap to reduce carbs.
• Sauce twist: Stir 1–2 tablespoons plain yogurt into the slaw dressing for a tangier finish.

Common questions

Q: Can I use chicken breasts instead of thighs?
A: Yes. Use the same marinade, but watch cooking time — breasts cook faster and can dry out. Aim for 160–165°F internal temp and rest before slicing.

Q: How long should I marinate the chicken?
A: At least 30 minutes for surface flavor; 2–4 hours is ideal. Overnight is fine, but no longer than 24 hours to avoid mushy texture from the acids.

Q: Is gochujang very spicy?
A: Gochujang is spicy but also sweet and savory. Heat level varies by brand; start with 1 tablespoon if sensitive and add more to taste.

Q: Can I make this ahead for a party?
A: Yes. Cook the chicken and make the slaw earlier in the day. Reheat chicken gently and toast buns just before serving. Keep components separate to preserve texture.

Q: How do I make the reserved marinade safe to use as a sauce?
A: Bring it to a rolling boil for at least 1–2 minutes to kill bacteria from raw chicken, then reduce to thicken into a glaze.
