Gochujang Chicken Sandwich with Crispy Potato Chip Crust

Crispy, saucy, and packed with bold flavor, this Gochujang chicken sandwich is anything but boring. Between the crunchy potato chip crust and the spicy-sweet sauce, it’s seriously hard to put down.

The Kind of Chicken Sandwich You Don’t Share

There’s no shame in admitting it — this is exactly the kind of sandwich I love making. Between the crazy crispy potato chip crust (it’s so me) and that sticky, spicy Gochujang sauce, it’s one of those messy, two-hand, no-bites-for-anyone-else situations. It’s crispy, it’s saucy, and it’s loaded with just enough heat to keep you diving back in.

I wanted this one to have all the bold, punchy flavors I’m into, with a little Korean-inspired twist from the Gochujang and kimchi. The air fryer keeps the chicken juicy and the crust light, and the quick cucumber salad and kimchi add that extra crunch and brightness I’m always after. It’s all the good parts of comfort food, just done my way.

If you’re into sandwiches that don’t hold back — hot, crispy, saucy, a little messy — this one’s it. Built for big bites, stacked with all the stuff I like throwing into a sandwich, and absolutely not meant for sharing.

This One’s Messy (and That’s the Best Part)

There’s no clean, careful way to eat this sandwich. The crispy potato chip crust is tough enough to hold up under all that sauce, but once you pile on the cucumber salad and kimchi, it’s a full-on two-hand, elbows-out kind of situation. And it’s better because of it.

The messiness is what makes it feel fresh and fun instead of boring. You get the crunch, the juicy chicken, the sticky heat from the Gochujang, and the cool, sharp bite from the quick salad all crashing together in every bite. It’s layered, bold, and chaotic, just the way a really good sandwich should be.

What I Love About This Gochujang Chicken Sandwich

• The potato chip crust stays crazy crispy even after the sauce hits it.
• The Gochujang sauce is messy, spicy, sweet, and exactly the right kind of sticky.
• The cucumber salad and kimchi bring the kind of crunch I always want piled on top.

Ingredients

Here’s what you’ll need to make the crispy chicken, the sticky sauce, and the quick cucumber salad:

• Boneless, skinless chicken thighs – stay juicy during air frying and make the base of the sandwich.
• All-purpose flour (or gluten-free flour) – lightly coats the chicken before the crust goes on.
• Garlic powder and black pepper – season the flour dredge for extra flavor.
• Eggs – help the crushed potato chips stick to the chicken.
• Thin, crispy potato chips – create the crunchy coating that holds up under the sauce.
• Low-sodium soy sauce – (or tamari) used in both the cucumber salad and sticky Gochujang sauce for salty flavor.
• Gochujang (Korean chili paste) – brings the spicy-sweet heat to both the sauce and cucumber salad. I also use it in my slow cooker Korean BBQ chicken for the perfect flavor.
• Ginger paste – adds depth to the sticky sauce.
• Brown sugar – rounds out the heat in the sauce with a little sweetness.
• Toasted sesame oil – used in both the sauce and cucumber salad for a nutty finish.
• Water – thins the sauce enough to simmer and coat the chicken.
• English cucumber – slices up for a fresh, crunchy salad topping.
• Rice wine vinegar – brightens and sharpens the cucumber salad.
• Sesame seeds – add a little crunch and nuttiness to the cucumber salad.
• Fresh garlic cloves and green onion – punch up the flavor in the cucumber salad.
• Gochugaru (Korean pepper flakes) or crushed red pepper flakes – kicks up a little extra heat in the salad.
• Mayo – spreads inside the toasted buns for a rich, creamy layer.
• Cabbage kimchi – piles onto the sandwich for extra crunch, tang, and funk.
• Buns like brioche – or ciabatta rolls will give you a sturdy base to hold all the layers.
• Butter – toasts the buns until golden and crisp.

How to Make It

Find the complete recipe with measurements in the recipe card at the bottom of the post.

• Step One (Make the cucumber salad):
  Slice up the cucumber nice and thin and toss it into a bowl. Add the rice wine vinegar, soy sauce, toasted sesame oil, sesame seeds, garlic, green onion, Gochugaru, and Gochujang. Give everything a good toss so it’s coated, then stick it in the fridge to hang out while you work on the rest.
• Step Two (Get your dredging station ready):
  Set up three shallow plates. One gets the flour, garlic powder, and black pepper mixed together. Beat the eggs into another. Then spread out the crushed potato chips on the third. It’s easier to have it all lined up before you start handling the chicken.
• Step Three (Coat the chicken):
  Grab a chicken thigh and dunk it through the flour first, then the eggs, and finally the crushed chips. Really press it into the chips so you get a good thick crust. This is what’s going to make it so crispy.
• Step Four (Air fry the chicken):
  Preheat your air fryer to 380ºF. Lay the coated chicken in the basket and air fry for 15–18 minutes, flipping halfway through. You’re looking for a golden, crunchy outside and a juicy inside, 165ºF when you check it. If the thighs are thick, give them a few extra minutes.
• Step Five (Whisk up the sauce):
  While the chicken’s cooking, grab a bowl and whisk together the soy sauce, Gochujang, ginger paste, brown sugar, toasted sesame oil, and water. Pour it into a skillet and let it bubble over medium heat until it thickens up enough to coat the chicken.
• Step Six (Coat the chicken):
  As soon as the chicken’s done, brush or spoon the warm sauce all over it. Flip it around and get every bit covered — no dry spots.
• Step Seven (Toast the rolls):
  Melt some butter in a skillet and lay the buns cut-side down. Let them toast until they’re golden and crisp. If you’re doing a bunch, just add a little more butter as you go.
• Step Eight (Build the sandwiches):
  Spread a little mayo inside each toasted bun. Stack a piece of sauced crispy chicken on the bottom, pile on some cucumber salad, add a scoop of kimchi, and cap it with the top bun. Dig in while it’s hot and messy.

Recipe Tips

This sandwich is already big on flavor, but there are a few easy ways to switch things up depending on what you’re feeling:

• Swap out the potato chips for kettle chips if you want a thicker, even crunchier crust, just know they’ll break off a little easier once the sauce goes on.
• Add some thinly sliced jalapeños to the cucumber salad if you want extra heat layered into every bite.
• If you love extra saucy sandwiches, double the sauce recipe and drizzle some directly onto the bun before stacking everything together.
• Try buttering and grilling the buns after you spread the mayo, it gives the bread an extra golden crust and a little more richness.
• If you want a shortcut, you can skip the cucumber salad and just pile on extra kimchi, it’ll be a little messier, but even bolder.
• Use a mix of regular and sweet potato chips for a slightly sweeter, deeper-flavored crust if you’re feeling experimental.
• Gochujang is one of my favorite ingredients to cook with. It’s the same fermented Korean chili paste I use in recipes like my sticky gochujang steak bites and ground turkey stir-fry.

Storage and Leftovers

If you somehow end up with leftovers, here’s the best way to keep everything tasting good:

• Store the cooked chicken in an airtight container in the fridge for up to 3 days.
• Keep the cucumber salad and kimchi separate so the chicken stays crispy and doesn’t get soggy.
• To reheat the chicken, pop it in the air fryer at 350ºF for a few minutes until it’s hot and crispy again.
• It’s better to toast fresh buns when you’re ready to rebuild a sandwich instead of storing already assembled ones.

Frequently Asked Questions

• Can I use chicken breasts instead of thighs for this sandwich?
  You can, just slice them horizontally to create thinner cutlets so they cook evenly. Thighs will stay juicier though, but if you prefer white meat, it still works.
• What’s the best way to keep the potato chip crust from falling off?
  Press the crushed chips firmly into the chicken after dredging, and let the coated chicken rest for a few minutes before air frying. It gives the crust a chance to stick better when it hits the heat.
• Is there a way to make the Gochujang sauce even spicier?
  Yep, just stir in a little extra Gochugaru or a splash of chili oil when you’re simmering the sauce. It’ll deepen the heat without throwing off the sticky texture. If you’ve never cooked with Gochujang before, Maangchi has a great breakdown of what it is and how it’s used in Korean cooking.
• Can I make the cucumber salad ahead of time?
  Yes, I hope you do. The salad gets better if you let it sit for a few hours. Just keep it in the fridge and give it a quick toss before using so the dressing stays even.
• What kind of potato chips work best for the crust?
  Regular thin, crispy chips coat best. Kettle chips will give you a thicker crunch, but they can break off more easily once sauced.
• What if I’ve never tried kimchi before, what should I know?
  Kimchi’s kind of its own thing. It’s fermented, a little funky, a little tangy, and sometimes spicy depending on the brand. If you’re new to it, I’d go for a classic cabbage kimchi and look for one that says “mild” if you’re not sure. It adds a sharp crunch to the sandwich without taking over the whole flavor.
• Where do you usually find kimchi at the store?
  Most grocery stores keep it in the refrigerated section, usually near the tofu or miso. Some brands make shelf-stable versions, but I stick with the ones in the fridge, they just taste fresher and have a better crunch.

More Recipes to Try

If you’re into bold flavors and love finding new ways to use kimchi, here are a few more recipes where I like to explore less traditional ways to use it:

• Cheesy Kimchi Colcannon — creamy mashed potatoes, melty cheese, and tangy kimchi all smashed together in the best way.
• Cheesy Kimchi Butter-Ranch Bread — a ranch-spiked kimchi butter gets slathered on bread and baked like a next-level garlic bread.
• Macaroni N’ Kim-Cheese — a mac and cheese situation that’s rich, gooey, and spiked with kimchi for a little bite. It tastes like something you’d get off a food truck.

• 2 large eggs
• 1-1/2 cups crushed, thin potato chips
• 4 (each thigh approx. 4-5 oz.) boneless, skinless chicken thighs or thigh fillets

Sauce:

• 3 tbsps. Gochujang (Korean chili paste)*
• 1 tbsp. ginger paste
• 3 tbsps. light brown sugar
• 1/2 tsp. toasted sesame oil
• 1 cup water

Assembly:

• 4 tbsps. butter (for toasting buns)
• 4 buns (such as brioche) or ciabatte rolls
• 2 tbsps. mayonnaise
• 1/2 cup cabbage kimchi

Instructions

• In a medium bowl, toss the cucumber with the rice wine vinegar, soy sauce, toasted sesame oil, sesame seeds, garlic, green onion, Gochugaru, and Gochujang. Cover and refrigerate for at least 30 minutes.
  1 large English cucumber, 1/3 cup rice wine vinegar, 1 tbsp. low-sodium soy sauce, 1/2 tsp. toasted sesame oil, 1 tsp. sesame seeds, 2 cloves garlic, 1 green onion (green top), 1 tsp. Gochugaru (Korean pepper flakes), 1 tbsp. Gochujang (Korean chili paste)*
• Set up three shallow plates: one with the flour, garlic powder, and black pepper mixed together, one with the beaten eggs, and one with the crushed potato chips.
  1/2 cup all-purpose flour, 1/2 tsp. garlic powder, 1/2 tsp black pepper, 2 large eggs, 1-1/2 cups crushed, thin potato chips
• Dredge each chicken thigh in the flour mixture, dip it in the egg wash, and coat it completely in crushed potato chips.
  4 (each thigh approx. 4-5 oz.) boneless, skinless chicken thighs or thigh fillets
• Preheat the air fryer to 380ºF. Air fry the chicken for 15–18 minutes, flipping halfway through, until golden and cooked through with an internal temperature of 165ºF.
• While the chicken cooks, whisk the soy sauce, Gochujang, ginger paste, brown sugar, toasted sesame oil, and water together in a bowl. Transfer the sauce to a skillet and simmer over medium heat until slightly thickened, about 5–8 minutes.
  2 tbsps. low-sodium soy sauce, 3 tbsps. Gochujang (Korean chili paste)*, 1 tbsp. ginger paste, 3 tbsps. light brown sugar, 1/2 tsp. toasted sesame oil, 1 cup water
• When the chicken is done, coat each piece generously with the warm sauce.
• Melt 1 tablespoon of butter at a time in a medium skillet. Toast the rolls cut-side down until golden, adding more butter as needed.
  4 tbsps. butter, 4 buns (such as brioche)
• Spread a little mayo on the inside of each bun. Layer a piece of sauced crispy chicken on the bottom, then top with cucumber salad and kimchi. Add the top bun and serve.
  2 tbsps. mayonnaise, 1/2 cup cabbage kimchi

Notes

• If you can’t find ginger paste in the produce section, it’s easy to make your own. Just grate fresh ginger on a microplane or the fine side of a box grater until you have a smooth, paste-like consistency.
• You can adjust the heat by using a little less Gochujang if you want it milder, or stir in a pinch of Gochugaru or crushed red pepper if you want it hotter.
• *Make sure you’re using Gochujang paste, not Gochujang hot sauce or just Gochujang sauce — the paste is thick, rich, and fermented, and it’s what gives the sauce its texture and depth.

Additional Tips:

• Bread options: Ciabatta, brioche, or toasted sandwich rolls all work great. Choose something sturdy enough to hold the saucy chicken and toppings.
• Potato chips: Thinner, crisper-style chips work best for coating. Thicker kettle chips tend to break off more easily.
• Cooking alternative: If you don't have an air fryer, you can bake the coated chicken on a wire rack over a sheet pan at 400ºF for about 20–25 minutes, flipping halfway through.
• Kimchi tip: Use cabbage kimchi that's more fermented and juicy for the best flavor contrast against the crispy chicken.
