intro

Crispy, juicy buttermilk fried chicken coated in bold spicy seasoning, stacked with tangy pickles and zesty mayo on a toasted brioche bun—satisfying, flavor-packed comfort food.

Ingredients

Boneless, skinless chicken thighs 680 grams (4 pieces, pounded to 1cm uniform thickness)
Buttermilk 240 ml (1 cup)
Cayenne-based hot sauce (e.g. Frank's RedHot) 75 ml (1/3 cup, divided)
All-purpose flour 180 grams (1.5 cups)
Cornstarch 30 grams (2 tablespoons)
Smoked paprika 7 grams (1 tablespoon)
Cayenne pepper 4 grams (2 teaspoons)
Garlic powder 3 grams (1 teaspoon)
Onion powder 3 grams (1 teaspoon)
Kosher salt 10 grams (2 teaspoons)
Freshly ground black pepper 2 grams (1 teaspoon)
Vegetable frying oil (canola or peanut) 960 ml (4 cups)
Brioche hamburger buns (split) 4 each
Unsalted butter (melted) 28 grams (2 tablespoons)
Crinkled dill pickle slices 60 grams (12 slices)
Mayonnaise 80 grams (1/3 cup)
Dill pickle brine 15 ml (1 tablespoon)

Steps

1

Marinate the chicken

First, pound each chicken thigh to an even 1cm thickness between two sheets of plastic wrap to ensure even cooking. In a shallow dish, whisk together 240ml buttermilk and 60ml of the hot sauce, then add the chicken, turning to coat fully. Let marinate at room temperature for 10 minutes while you prep the coating and heat oil (or up to 12 hours in the fridge for deeper flavor).

Step 1
step1：Marinate the chicken
2

Mix spicy flour coating

In a separate shallow dish, whisk together 180g all-purpose flour, 30g cornstarch, 7g smoked paprika, 4g cayenne pepper, 3g garlic powder, 3g onion powder, 10g kosher salt, and 2g black pepper until fully combined. Remove one chicken piece at a time from the marinade, letting excess buttermilk drip off, then press firmly into the flour mixture on all sides to create a thick, craggy coating; set coated pieces on a wire rack for 5 minutes to let the coating adhere before frying.

Step 2
step2：Mix spicy flour coating
3

Heat frying oil

Pour 960ml vegetable oil into a deep, heavy-bottomed Dutch oven or deep fryer, and heat over medium-high heat until it reaches a steady 175°C (350°F), measured with a candy thermometer. Maintain this temperature throughout cooking to avoid greasy, undercooked chicken; adjust burner heat as needed if oil climbs above 180°C (355°F) or drops below 165°C (325°F).

Step 3
step3：Heat frying oil
4

Fry chicken until crispy

Carefully lower 2 coated chicken pieces into the hot oil at a time, do not overcrowd the pot. Fry for 6-7 minutes total, flipping once halfway through at the 3 minute mark, until the coating is deep golden brown and crispy, and the internal temperature of the chicken reaches 74°C (165°F) on an instant-read thermometer. Transfer cooked chicken to a clean wire rack set over a baking sheet to drain, and repeat with the remaining 2 pieces.

Step 4
step4：Fry chicken until crispy
5

Toast buns and make sauce

While chicken rests for 2 minutes after frying, brush the cut sides of the 4 split brioche buns with 28g melted butter, then toast cut-side down in a dry skillet over medium heat for 1-2 minutes until light golden and crisp. In a small bowl, stir together 80g mayonnaise, remaining 15ml hot sauce, and 15ml dill pickle brine until smooth to make the spicy spread.

step5：Toast buns and make sauce
6

Assemble the sandwiches

Spread 1 tablespoon of the spicy mayo evenly on the cut sides of each toasted bun. Place one crispy fried chicken patty on the bottom bun, top with 3 dill pickle slices, then close with the top bun. Serve immediately while the chicken is hot and the coating is crisp.

Step 6
step6：Assemble the sandwiches

Tips

1.Letting flour-coated chicken rest on a wire rack for 5 minutes before frying prevents the breading from sliding off during cooking, and builds an extra craggy, ultra-crispy crust.
2.Never overcrowd the frying pot, as this drops oil temperature rapidly and results in soggy, grease-soaked chicken instead of a light, crisp coating; fry in small batches for best results.
3.Adjust heat level to your preference: add an extra 1 teaspoon (2g) of cayenne to the flour coating for extra burn, or reduce cayenne to 1/2 teaspoon for a milder sandwich.

Spicy Chicken Sandwich:Frequently Asked Questions

1.Why do you use boneless, skinless chicken thighs instead of breasts for this sandwich? ▾
Chicken thighs have a slightly higher fat content that keeps the meat ultra juicy and flavorful through high-heat frying, no dry, bland bites you often get with lean breasts. Just pound them to an even ½-inch thickness before brining so they cook uniformly and fit perfectly on your brioche bun.
2.Can I skip the buttermilk brine if I’m short on time? ▾
I don’t recommend skipping it entirely if you want that classic tangy, tender fried chicken bite, but if you’re crunched for time, cut the brine time to 30 minutes at room temperature instead of the full 4 hours in the fridge. The acid in buttermilk also helps build that shaggy, crisp crust, so don’t skip the ingredient entirely.
3.What does adding cornstarch to the flour coating do? ▾
Cornstarch is the secret to that extra shatteringly crisp crust that doesn’t get soggy quickly, even when you stack on sauce and pickles. It cuts the gluten in all-purpose flour so the coating doesn’t turn tough or chewy as it fries, giving you that light, crunchy bite every time instead of a dense, bready crust.
4.How spicy is this sandwich, and can I adjust the heat level? ▾
The base recipe has a warm, approachable zing from cayenne-based hot sauce (like Frank’s RedHot) in the brine and seasoning, not burn-your-mouth heat. For milder sandwiches, cut the hot sauce in half; for extra heat, add a pinch of cayenne to the flour, spike your mayo with extra hot sauce, or top with pickled jalapeños.
5.Why do you recommend toasting the brioche bun? ▾
Toasting your brioche bun does two key jobs: first, it adds a warm, nutty, buttery flavor that pairs perfectly with the crispy chicken and tangy toppings. Second, it creates a slight moisture barrier on the cut side of the bun so it doesn’t get soggy from mayo or chicken juices as you eat.
6.How do I get that craggy, crispy crust that actually sticks to the chicken? ▾
After pulling chicken out of the buttermilk brine, dredge it in the flour and cornstarch mix, press the coating firmly into every surface, then let the chicken rest on a wire rack for 10 minutes before frying. That rest time lets the coating set so it doesn’t slide off in oil, creating those craveable craggy crisp bits.
7.What type of oil works best for frying the chicken? ▾
Stick to neutral, high-smoke-point oils like canola, vegetable, or peanut oil for this recipe. They won’t add off flavors to your chicken, and they hold up well to the 350°F frying temperature you need for a crisp crust that doesn’t absorb excess oil and turn greasy. Skip olive oil, which has too low a smoke point for this use.
8.Can I make this chicken in an air fryer instead of deep frying? ▾
You absolutely can, for a lighter, less messy take! Spray your coated chicken generously with oil on all sides, then air fry at 380°F for 18-20 minutes, flipping halfway, until the internal temp hits 165°F and the crust is crisp. It won’t be quite as shatteringly crisp as deep-fried, but it’s still totally delicious.
9.How long should I brine the chicken in buttermilk and hot sauce for best results? ▾
For the juiciest, most tangy, well-seasoned chicken, brine the thighs in the buttermilk and hot sauce mix for 4 to 12 hours, covered, in the fridge. Any longer than 24 hours and the acid in the brine can make the outer texture of the chicken mushy instead of tender, so stick to that window.
10.Why are pickles the recommended topping, and can I swap them out? ▾
Tangy, briny dill pickles cut through the richness of the fried chicken and creamy mayo perfectly, balancing every bite so the sandwich doesn’t feel heavy. If you aren’t a pickle fan, swap them for tangy coleslaw, pickled red onions, or sliced ripe tomato—just stick to something bright and acidic for balance.
11.How do I make sure the chicken cooks through without burning the crust? ▾
Keep your frying oil held steady at 350°F—if it’s too hot, the crust will burn before the chicken cooks through, and if it’s too cool, the crust will soak up excess oil and turn greasy. Fry ½-inch thick thighs for 6-7 minutes total, and verify doneness with a meat thermometer for 165°F at the thickest point.
12.Can I prep components of this sandwich ahead for quick weeknight meals? ▾
Absolutely! You can brine the chicken in the buttermilk mix for up to 12 hours ahead, mix up your zesty spicy mayo 3 days ahead, and keep your pickles chilled and ready to go. Wait to dredge and fry the chicken, and toast your buns, right before assembling for the best texture and zero sogginess.
13.What’s in the zesty mayo, and can I use store-bought spicy mayo? ▾
The classic homemade zesty mix is ½ cup mayo stirred with 1 tablespoon of that same cayenne hot sauce, a pinch of garlic powder, and a small squeeze of lemon for brightness. You can absolutely use store-bought spicy mayo to save time—just stir in a splash of pickle brine to amp up that tangy, perfect pairing flavor.
14.My last batch had soggy crust instead of crispy coating—what went wrong? ▾
Soggy crust almost always traces back to one of three issues: your oil was too cold when you added the chicken, you overcrowded the fryer which dropped the oil temp too fast, or you skipped letting the dredged chicken rest before frying. Next time, work in small batches, monitor oil temp, and let the coating set 10 minutes pre-fry for perfect crunch.

OMG this crispy spicy chicken sandwich is a total game changer! I made it for our Sunday family dinner last night and even my super picky 10 year old asked for seconds. The crunch on the chicken is insane, and the spice level is perfect—not so hot that my kids complained, but enough zing to keep the adults happy. 10/10 will be adding this to our weekly meal prep rotation!

yesterday

Wait did you use regular paprika or smoked paprika for the coating? I’m making these for a potluck this weekend and want to get the flavor exactly right!

yesterday

So glad your whole family loved it, Mia! @Jake M. we recommend smoked paprika for that extra depth of flavor, but regular works great too if that’s what you have on hand—just add a tiny pinch of cayenne if you want a little extra kick for your potluck crowd!

1 week ago

SO good, but I messed up the first batch because I had my oil too hot—burnt the outside before the chicken cooked all the way through! Turned the heat down to medium for batch two and it came out perfectly crispy, juicy inside, just like the photos. Pro tip: don’t skip the pickle brine soak, that’s what makes the chicken so flavorful!

5 days ago

Oh thank you for the oil temp tip! I almost always burn fried chicken on the first go, I’ll make sure to keep it at medium when I make these tomorrow for game night

5 days ago

Great catch on the oil temp, Tyler! We recommend keeping oil between 350-375°F for the best results—so glad you adjusted and got that perfect crispy, juicy bite on your second batch!

Made these for my partner’s birthday cookout and every single person asked for the recipe! I did add a little extra hot honey to the sauce because we love sweet heat, and it was chef’s kiss. The only downside is my hands were covered in flour breading the chicken, but that’s 100% a me problem, not the recipe’s fault lol

2 days ago

Hot honey addition sounds incredible, Luna—we love that customization! A little trick for less mess: set up your breading station with one hand for dry ingredients and one for wet to cut down on the clumpy flour fingers 😊

yesterday

The hot honey idea is genius! I’m definitely trying that next time—last time I made these I added pickled jalapeños on top and it slapped too

Wait, is there an easy swap to make this gluten free? My roommate has celiac and I want to make these for our apartment movie night next week, but I’m worried gluten free breadcrumbs will get soggy instead of crispy. Has anyone tried it yet?

5 minutes ago

Great question, Sophie! Gluten free panko works perfectly as a 1:1 swap here. You can also use crushed gluten free rice cereal if you don’t have panko on hand for that same shatteringly crisp crust!

yesterday

Took me a little longer than 35 minutes because I prepped all the toppings and made my own spicy mayo, but it was so worth the extra time. Better than any fast food spicy chicken sandwich I’ve ever had, no cap. I even added coleslaw on top for extra crunch

2 hours ago

Homemade spicy mayo and coleslaw sound like the perfect upgrades, Derek! The total time can shift a little if you’re making extra toppings, so we’re stoked it was worth the extra effort for you!

My kids loved it! I was worried the spice would be too much for them so I left the cayenne out of half the breading for their portions, and they devoured their sandwiches before my husband and I even sat down. Will be making these again for our next tailgate for sure

3 days ago

Great idea to split the breading for the kids! I’ve been making my son’s portion with a little paprika no cayenne for months and he goes crazy for it, perfect tailgate food

Pretty good, but I felt like the breading slid off a couple pieces when I was frying. Did I not let the buttermilk soak long enough? I only did 30 minutes because I was in a rush, maybe that was the issue?

30 minutes ago

Hi Zara! That breading slide usually happens if the chicken is too wet when you dip it in the flour mix, or if the oil isn’t hot enough when you add the chicken. Letting the buttermilk soak for a full hour helps the coating stick better too—give it another try next time and let us know how it goes!

Made these for a potluck at work last week and people were coming back for thirds. I used brioche buns toasted in butter like the recipe said and that little touch makes such a huge difference, don’t skip toasting the buns y’all!

5 days ago

The butter toasted brioche is non-negotiable! I tried it with regular hamburger buns once and it just wasn’t the same, the brioche holds up to all the sauce and crispy chicken so much better

2 weeks ago

Meal prep win! I cooked a big batch of the chicken breasts on Sunday, kept them in the fridge, and just reheated them in the air fryer for 3 minutes when I was ready to eat all week. Stayed juicy, the crisp came right back, saved me so much money on takeout lunches

just now

10/10 no notes. I’ve tried like 6 different spicy crispy chicken sandwich recipes off this site and this is the only one that’s gotten the crunch exactly right every single time I make it. No sad soggy breading, no dry chicken, just perfect every time.

5 minutes ago

Difficulty is definitely medium, don’t go into this thinking it’s a 15 minute weeknight meal if you’re new to frying! I’m a pretty novice cook and it took me about 45 minutes total, but the instructions were super clear and it came out amazing even with my messy beginner breading job.

2 days ago

Game changer for vegetarians too! I swapped the chicken for thick cut cauliflower steaks, soaked them in the same pickle brine and buttermilk, used the same breading, and it was so crispy and spicy even my meat-obsessed brother was stealing bites off my plate. Obsessed!
