Buttermilk Marinade

  • 4 pieces boneless skinless chicken thighs pounded to even thickness
  • 1 cup buttermilk see notes below for an homemade alternative
  • 2 tbsp Sriracha or your favorite hot sauce
  • 1 tsp each salt, pepper, garlic powder

Flour Mixture

  • 1 cup all-purpose flour
  • 3 tbsp cornstarch
  • 1 tbsp paprika powder
  • 1 tsp each salt, pepper, garlic powder, cayenne powder reduce cayenne for less spice

Sriracha Mayo

To assemble

  • cooking oil for frying
  • 4 burger buns lightly toasted with butter
  • lettuce, tomato, and/or pickles sliced, or your choice of toppings


  • In a medium bowl, combine buttermilk, Sriracha, salt, pepper, and garlic powder. Add chicken thighs and marinate in the fridge for at least 4 hours or overnight.
  • Whisk together flour, cornstarch, paprika, salt, pepper, garlic powder, and cayenne powder in a large bowl.
  • Add 2 tbsp of the marinade to the mixture and mix with a fork. Dredge the chicken with the flour mixture, making sure each piece is evenly coated. Prepare the sauce by mixing together Sriracha and mayonnaise.
  • Heat oil in a deep skillet until it reaches 350˚F (180˚C). Fry the chicken for about 3-4 minutes on each side, or until golden brown. The thickest part of the chicken should register 165˚F (75˚C).
  • Generously spread the Sriracha mayo on both sides of the buns and add your preferred toppings and the chicken. Serve immediately and enjoy!


To make homemade buttermilk: combine a cup of milk with a tablespoon of white vinegar or lemon juice. Stir these ingredients together and set aside for 5 minutes before mixing in the spices.
