Ingredients

Chicken

1 pound chicken breast (2 small breasts)
¾ cup buttermilk
1 large egg
2 teaspoons salt

Breading

¾ cup flour
4 tablespoons cornstarch
1 teaspoon garlic powder
½ teaspoon onion powder
1 teaspoon paprika
¼ teaspoon mustard powder optional
¾ teaspoon salt
1 teaspoon black pepper
⅛ up to ¼ teaspoon cayenne pepper optional, for a spicy chicken sandwich

Frying & Assembly

4 cups vegetable oil
4 brioche buns plus softened butter
4 lettuce leaves
1 large tomato thinly sliced
4 slices sharp cheddar cheese thinly sliced
Pickles optional
1 batch Chick-Fil-A sauce or store-bought

Directions

1. Place chicken breasts between two long sheets of plastic wrap. Pound to an even ½-inch thickness. Slice to slightly larger than your bun size. Save any extra pieces for nuggets if desired.

2. In a large bowl, whisk together buttermilk, egg, and salt. Remove 2 tablespoons of the mixture and set aside. Add chicken to the bowl and coat well. Cover and marinate in the refrigerator for at least 1 hour or up to 24 hours.

3. In a separate bowl, whisk together flour, cornstarch, garlic powder, onion powder, paprika, mustard powder (if using), salt, black pepper, and cayenne. Add the reserved 2 tablespoons of marinade to the dry mixture and mix with your fingers to form small clumps for extra crispiness.

4. Pour vegetable oil into a large heavy pot over medium-high heat. Heat to 350°F, keeping the temperature steady for best results.

5. Using tongs, remove chicken from the marinade and let excess drip off. Press into the breading mixture on both sides, coating thoroughly. Shake off excess breading.

6. Carefully lower chicken into the hot oil. Fry for 2 minutes without touching, then flip and fry for 2 more minutes until golden and cooked through. Remove to a wire rack and immediately top with cheese if using. Fry no more than 2 pieces at a time. Repeat with remaining chicken.

7. Lightly butter the brioche buns and toast in a dry skillet until golden.

8. Spread sauce generously on both sides of the buns. Layer with lettuce, tomato, fried chicken, and pickles if desired. Add the top bun and serve immediately.

Variations

Spicy version: Increase the cayenne pepper or add hot sauce to the buttermilk marinade.

Grilled option: Skip the breading and grill the marinated chicken instead.

Different cheeses: Try pepper jack, Swiss, or American cheese.

Extra crunch: Add coleslaw on top for added texture.

Healthier swap: Use whole wheat buns or air fry the chicken.

Storage/Reheating

Store fried chicken in an airtight container in the refrigerator for up to 3 days. Keep sauce stored separately for up to 3 days as well.

For best results, reheat the chicken in a 375°F oven or air fryer until heated through. This helps restore some crispiness, though it may not be as crispy as freshly fried. Assemble sandwiches just before serving to prevent soggy buns.

FAQs

How do I know when the chicken is fully cooked?

The internal temperature should reach 165°F when checked with a meat thermometer.

Can I marinate the chicken overnight?

Yes, marinating up to 24 hours enhances flavor and tenderness.

Why add cornstarch to the breading?

Cornstarch helps create a lighter, crispier crust.

Can I use chicken thighs instead of breasts?

Yes, boneless skinless thighs work well and stay very juicy.

What oil is best for frying?

Vegetable oil, canola oil, or peanut oil are great choices due to their high smoke points.

Can I make this in an air fryer?

Yes, spray lightly with oil and cook at 375°F until golden and cooked through.

How do I keep the coating from falling off?

Make sure to press the breading firmly onto the chicken and let excess marinade drip off before coating.

Can I freeze the fried chicken?

Yes, freeze cooked chicken in an airtight container for up to 2 months and reheat in the oven.

What sauce works best?

A creamy sandwich sauce like Chick-Fil-A style sauce, honey mustard, or spicy mayo pairs perfectly.

Why toast the buns?

Toasting prevents sogginess and adds extra flavor and texture.
