Pin It The first time I bit into this sandwich, I was standing in my friend's tiny apartment kitchen in Bangkok. She'd spent the afternoon marinating chicken in buttermilk and red curry paste, something I'd never thought to combine. When she pulled that golden chicken from the oil, the whole neighborhood seemed to stop and smell what was happening.
Last summer, I made these for a backyard barbecue and watched my barbecue-purist uncle actually put down his rib to try one. He took one bite, went quiet for a full minute, then asked if I could teach him how to make the spicy mayo. Now he requests them for every family gathering.
Ingredients
- 4 boneless skinless chicken breasts: The buttermilk marinade will transform even the most basic chicken into something tender and flavorful
- 1 cup buttermilk: This isnt just for tenderness, it helps the curry paste penetrate deeper into the meat
- 2 tablespoons fish sauce: Dont be intimidated by the smell, it adds that essential umami depth you cant get anywhere else
- 2 tablespoons red curry paste: This is the secret weapon that makes this sandwich unforgettable
- 1 teaspoon garlic powder: Fresh garlic burns during frying, powder gives you flavor without the bitterness
- 1 teaspoon onion powder: Works with the garlic to create that classic fried chicken base flavor
- 1 cup all-purpose flour: Provides the structure for your crispy coating
- ½ cup cornstarch: This is what makes the exterior shatteringly crispy instead of just crunchy
- 1 teaspoon salt: Essential for bringing out all the flavors in the coating
- ½ teaspoon black pepper: Adds a gentle heat that complements the curry
- Vegetable oil: You need enough for about 2 inches of depth in your pan
- ½ cup mayonnaise: The creamy base for your spicy sauce
- 1 tablespoon sriracha: Adjust this up or down based on your heat tolerance
- 1 tablespoon fresh lime juice: Cuts through the richness and brightens everything
- 4 brioche buns: Their slight sweetness and pillowy texture are perfect for this sandwich
- 1 cup shredded cabbage: Provides the crucial crunch that contrasts with the crispy chicken
- ½ cup pickled carrots: Their acidity and sweetness balance all the rich fried elements
- Fresh cilantro leaves: Adds a bright herbal finish that makes everything taste fresh

Instructions
- Create the marinade magic:
- Whisk together buttermilk, fish sauce, red curry paste, garlic powder, and onion powder until the curry paste is fully dissolved into the liquid

- Mix your coating:
- Combine flour, cornstarch, salt, and pepper in a shallow dish, making sure to break up any cornstarch clumps
- Get your oil ready:
- Heat about 2 inches of vegetable oil in a deep pan or Dutch oven until it reaches 350 degrees
- Coat the chicken:
- Remove chicken from marinade, let excess drip off, then press firmly into the flour mixture to create an even coating
- Fry to perfection:
- Cook chicken for 6 to 8 minutes per side until golden and the internal temperature hits 165 degrees
- Whisk up the spicy mayo:
- Mix mayonnaise, sriracha, and lime juice until smooth, then taste and adjust the heat level

- Lightly grill or toast the brioche buns until they're just golden and warmed through
- Build your masterpiece:
- Spread spicy mayo on both bun halves, then layer with chicken, cabbage, pickled carrots, and cilantro before topping
Pin It My neighbor texted me at midnight once, begging for this recipe after smelling the frying chicken through our shared wall. She said it reminded her of the street food in Chiang Mai where she studied abroad. Now we make them together whenever she visits.
Making Your Own Pickled Carrots
If you cant find pickled carrots, thin-slice some carrots and let them sit in a mixture of rice vinegar, sugar, and salt for about 30 minutes. Theyll be perfect by the time your chicken is done frying.
The Perfect Fry Temperature
Ive learned that keeping an instant-read thermometer near your frying station is essential. Too cool and the chicken gets greasy, too hot and the outside burns before the inside cooks. 350 degrees is your sweet spot.
Assembly Secrets
The order of ingredients matters more than you might think. I always put the spicy mayo directly on the bun to prevent it from getting soggy, then layer the cabbage against the chicken so it stays crisp.
- Toast the cut side of the buns for better structure
- Let fried chicken rest for 2 minutes before assembling
- Spread mayo all the way to the edges of the bun
Pin It There's something magical about biting through that crispy coating into the tender, curry-spiced chicken while the cool vegetables and spicy mayo bring everything together. It's the sandwich that keeps people coming back.
Recipe Questions & Answers
- → Can I use chicken thighs instead of breasts?
Yes, boneless skinless chicken thighs work beautifully and stay extra juicy. Adjust frying time to 8-10 minutes depending on thickness.
- → What can I substitute for fish sauce?
Soy sauce provides similar salty depth, though the Thai flavor profile will be slightly different. Use 1 tablespoon soy sauce instead of fish sauce.
- → How spicy is this sandwich?
The heat level is medium thanks to sriracha and red curry paste. You can easily adjust by adding more or less sriracha to the mayo.
- → Can I bake the chicken instead of frying?
Baking at 425°F for 20-25 minutes works, though you won't get the same crispy texture. Spray with oil for better browning.
- → How long does the chicken need to marinate?
Minimum 2 hours for good flavor absorption, but overnight marinating yields the most tender and flavorful results.
- → Can I make components ahead?
The spicy mayo can be made 2-3 days ahead. Pickled carrots last 1 week in the fridge. Fry chicken fresh for best texture.
