Ingredients

Buttermilk Marinade

  • 4 pieces boneless skinless chicken thighs pounded to even thickness
  • 1 cup buttermilk
  • 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 add more cayenne for extra spice

Sriracha Mayo

  • 1/2 cup mayonnaise
  • 2 tbsp Sriracha

To assemble

  • cooking oil for frying
  • 4 brioche buns lightly toasted with butter
  • lettuce, tomato, pickles sliced

Instructions

  • In a medium bowl, combine buttermilk, Sriracha, salt, pepper, and garlic powder. Add chicken thighs and marinate overnight, or at least for 4 hours.
  • Prepare the flour mixture by whisking together flour, cornstarch, paprika, salt, pepper, garlic powder, and cayenne powder in a shallow bowl.
  • Add 2 tbsp of the marinade into the mixture and mix through with a fork. Working with one piece at a time, dredge the chicken with the flour mixture, making sure it is completely coated.
  • In a small bowl, prepare the sauce by mixing together Sriracha and mayonnaise.
  • Heat the oil in a deep pan until it reaches 350˚F (180˚C). Fry the chicken for about 3-4 minutes on each side, or until cooked through and golden brown. The thickest part of the chicken should register 165˚F (75˚C).
  • Generously spread the Sriracha mayo on the toasted brioche buns, and top with sliced pickles, lettuce, and tomato. Serve immediately and enjoy!

Notes

To make homemade buttermilk: combine a cup of milk with 1-2 tablespoons of white vinegar or lemon juice. Stir these ingredients together and set aside for 10-15 minutes and the milk will slightly curdle and be ready to be used in the recipe!
