Start by mixing buttermilk and hot sauce in a bowl. Slice your chicken breasts in half horizontally to create thinner cutlets. Add them to the bowl, cover, and refrigerate for at least 1 hour. This makes the chicken extra juicy and lets the flavors soak in.
In a separate bowl, combine mayonnaise, Dijon mustard, honey, hot sauce, smoked paprika, and lemon juice. Add a bit of salt and pepper to taste. Whisk until smooth. Store in the fridge while the chicken marinates – the flavors deepen over time.
In a shallow dish, mix your flour with paprika, cayenne, garlic powder, onion powder, salt, and black pepper. This spiced mix gives your chicken that crave-worthy crispy crust.
Take the marinated chicken and let the excess buttermilk drip off. Dredge it in your seasoned flour. For an extra crispy crust, dip it back into the buttermilk and then re-coat with flour. This double-dip method is worth it!
Heat your oil to 350°F (use a thermometer if needed). Carefully add chicken pieces, frying for about 4–6 minutes per side, depending on thickness. The coating should be golden brown and the inside should reach 165°F. Set the cooked fillets on a wire rack to rest.
While the chicken rests, lightly butter your brioche buns and toast them in a skillet until golden. It adds that soft crunch and keeps the buns from getting soggy.
Now the fun part! Spread a generous layer of your creamy homemade sauce on the bottom bun. Add a few pickle slices, layer in the crispy chicken, and spoon more sauce on top if you love extra flavor. Place the top bun on and you’re done!
