Ingredients

Crispy Spicy Buttermilk Chicken

  • 4 chicken thighs or 1-inch thick chicken breasts boneless, skinless
  • 1 and ½ cups buttermilk
  • 1 large egg
  • cup hot sauce Louisiana style
  • 2 cups all-purpose flour
  • cup cornstarch
  • 3 tsp. smoked paprika
  • 2 tsp. chili powder
  • 2 tsp. cayenne pepper
  • 2 tsp. onion powder
  • 2 tsp. garlic powder
  • ½ tsp. ground mustard
  • 2 tsp. kosher salt
  • 1 tsp. black pepper
  • 2 and ½ cups canola oil for frying

Buttermilk Ranch Sauce

  • ½ cup buttermilk
  • ½ cup sour cream
  • ¼ cup mayonnaise
  • 1 tsp. apple cider vinegar
  • ½ tsp. garlic powder
  • ½ tsp. onion powder
  • tsp. dried mustard
  • ½ lemon juiced
  • 1 tbsp. fresh dill chopped
  • 1 tbsp. fresh chives chopped
  • pinch salt and pepper

Additional Ingredients

  • 4 brioche buns buttered and grilled on the flat side
  • iceberg lettuce shredded
  • dill pickle chips

Instructions

  • Prepare the marinade by whisking together the hot sauce, buttermilk and ground mustard in a medium-sized bowl. Set the marinade aside.
  • Place the chicken thighs or breasts in a casserole dish, and pour the buttermilk mixture over them. Let the chicken marinate in the refrigerator for 1-4 hours, or overnight.
  • Prepare the buttermilk-ranch sauce by whisking together all of the sauce's wet ingredients with the dry seasonings. Stir in the fresh chives and dill. Set aside, or chill in the refrigerator.
  • Prepare the seasoned coating by whisking together the flour, cornstarch and dry seasonings in a large bowl.
  • Pre-heat the oil to 350°F in a deep-sided dutch oven or large cast iron skillet.
  • Remove the chicken from marinade, shake off any excess marinade and set the chicken aside. Add 1 egg to the bowl of leftover marinade and whisk until the egg is fully disbursed.
  • Dredge each chicken breast/thigh in the seasoned flour, dip once more in the marinade and let the excess marinade drip off, then dredge in flour again.
  • Drop each breast/thigh in the hot oil and fry for 15-18 minutes. You can fry all 4 pieces of chicken in the same batch. Use a digital meat thermometer to measure the internal temperature of the chicken. The temperature needs to register at 170°F for thighs and 165°F for breasts.
  • Assemble the sandwiches in this order: Bottom bun, a thin layer of ranch, a few pickle chips, crispy chicken, another spoonful of ranch, shredded iceberg, a few more pickle chips, top bun.

Notes

  • It's always best to use a meat thermometer to take the guesswork out of frying chicken. Chicken breast should reach an internal temperature of 165°F and thigh meat should reach 170°F.
  • Grill the cut sides of the buns for just a few seconds before assembling the sandwiches.
  • Store leftover chicken in the refrigerator for up to 3 days, the ranch dressing will keep for about a week.
Alternative cooking methods:
  • Air fryer - place the dredged chicken in the air fryer basket and spray with a little bit of cooking spray. Air fry at 370°F for about 20 full minutes, make sure to flip the chicken half way through.
  • Bake in the oven on a greased metal baking sheet at 425°F for 25 minutes. Spray the tops with cooking spray.
