Step-by-Step Instructions
- Marinate the Chicken:
- Nestle the thinly sliced chicken breasts in a bowl and pour over the buttermilk. Make sure every piece is coated fully. Cover and refrigerate for at least thirty minutes or up to a full day. The longer the soak the juicier and more flavorful the chicken becomes.
- Mix the Coating:
- In a separate small bowl whisk together the flour cornstarch smoked paprika garlic powder cayenne and salt until completely blended. Patience here ensures every bite is seasoned all the way through.
- Dredge the Chicken:
- Lift each chicken breast out of the marinade letting extra buttermilk drip off. Coat thoroughly in the flour mixture then dunk back into remaining buttermilk and one last time into the flour blend. This double dip creates a thick crispy crust. Set coated pieces on a baking sheet to rest for at least ten minutes so the coating adheres properly.
- Fry the Chicken:
- Heat about four cups of vegetable oil in a deep heavy bottomed pot or Dutch oven to three hundred fifty degrees. Test with a thermometer for best results. When the oil shimmers and a pinch of flour sizzles add two chicken breasts at a time. Fry for six minutes or until the crust is a deep golden brown and the internal temperature reaches one hundred sixty five degrees. Transfer straight to a cooling rack or a plate lined with paper towels and immediately top each with a slice of cheese so it melts perfectly. Repeat for the remaining chicken.
- Prepare the Sriracha Mayo:
- Combine mayonnaise sriracha and sugar in a small bowl. Whisk until smooth. Taste and adjust sriracha for preferred heat.
- Assemble the Sandwich:
- Layer crispy chicken cheese cooked bacon and a generous spoonful of sriracha mayo onto fresh soft buns. Serve hot while the crust is at its peak crunch.

My favorite ingredient has to be the smoked paprika. It takes the flavor to another level and blends so beautifully with the heat from cayenne. The first time my son tried this he shimmied around the kitchen with pure delight and asked for seconds right away. Now it is a family tradition whenever spicy food is in order.
Storage Tips
Store any leftover fried chicken in an airtight container in the fridge. For best results lay paper towels between layers to keep the coating crisp. Reheat in a hot oven or toaster oven rather than microwaving which keeps the exterior crunchy and prevents sogginess. Sriracha mayo stays fresh in the fridge for up to one week.
Ingredient Substitutions
You can use thighs instead of breasts for extra juiciness just be sure to trim and flatten them so they cook through evenly. Sour cream thinned with a bit of milk works as a stand in for buttermilk in a pinch. Swap cheddar or pepper jack for the cheese if you like more bite or use turkey bacon for a lighter twist.
Serving Suggestions
These sandwiches are a meal in themselves but pair wonderfully with tangy slaw crisp pickles or oven fries. For extra freshness top with shredded lettuce sliced tomatoes or thin red onion. Sometimes I serve with extra sriracha mayo or a cooling ranch on the side for dipping.

Cultural Inspiration
The roots of fried chicken sandwiches run deep in American comfort food especially in the southern tradition of marinated fried chicken served on a soft bun. This version brings in modern heat and the creamy kick of sriracha mayo influenced by Asian flavors creating a craveable fusion that has quickly become a staple in many homes.
