Ingredients

Chicken & Marinade
- 2 large boneless skinless chicken breasts
- 1 cup buttermilk
- 1 tsp paprika
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp cayenne pepper (adjust to taste)
- ½ tsp salt
- ¼ tsp black pepper
Breading
- ¾ cup all-purpose flour
- ½ cup cornstarch
- 1 tsp smoked paprika
- 1 tsp garlic powder
- ½ tsp cayenne pepper
- ½ tsp salt
Sandwich Components
- 4 sandwich buns
- 4 leaves romaine lettuce
- 4 slices ripe tomato
- 4 tbsp mayonnaise
- 1 tbsp sriracha (or preferred hot sauce)
- Optional: pickles, cheese slices

Instructions

Prepare the Chicken: Slice chicken breasts horizontally if desired to create thinner fillets. Place chicken in a medium bowl and add buttermilk, paprika, garlic powder, onion powder, cayenne, salt, and black pepper. Mix until chicken is fully coated. Cover and refrigerate for at least 15 minutes (up to 2 hours for more flavor).
Prepare the Breading: In a shallow dish, combine flour, cornstarch, smoked paprika, garlic powder, cayenne, and salt. Mix thoroughly to ensure an even seasoning distribution.
Bread the Chicken: Remove each chicken piece from the buttermilk, letting excess drip off. Dredge in the flour mixture, pressing lightly to adhere a thick, even coating. For extra crunch, double-dip by dipping back into buttermilk, then into the flour mixture again.
Preheat the Air Fryer: Set your air fryer to 400°F (200°C) for 3–5 minutes to preheat.
Cook the Chicken: Lightly spray the air fryer basket with cooking spray. Place breaded chicken in a single layer (avoid overcrowding). Air fry at 400°F (200°C) for 10–12 minutes, flipping halfway, until chicken reaches an internal temperature of 165°F (74°C) and is golden brown.
Prepare the Spicy Mayo: In a small bowl, mix mayonnaise with sriracha until smooth. Adjust spice level to taste.
Assemble the Sandwich: Toast buns lightly if desired. Spread a layer of spicy mayo on the top and bottom buns. Place a lettuce leaf on the bottom bun, add a slice of tomato, then the crispy chicken fillet. Top with optional pickles or cheese, then cover with the top bun.
Serve and Enjoy: Serve immediately while hot and crispy. Pair with air fryer fries, sweet potato wedges, or a fresh salad for a complete meal.

Tips for the Perfect Air Fryer Spicy Chicken Sandwich

Even Thickness: Pound chicken to an even thickness for uniform cooking.
Extra Crunch: Add panko breadcrumbs to the flour mixture for a lighter, crunchier texture.
Marinating Time: Longer marination in buttermilk allows the chicken to absorb more flavor and remain tender.
Air Fryer Basket Care: Don’t overcrowd; cook in batches if needed for even crispiness.
Customize the Heat: Adjust cayenne and sriracha levels for mild, medium, or fiery spice.

Variations

Cheesy Spicy Chicken Sandwich: Add a slice of cheddar or pepper jack cheese on top of the chicken before closing the bun.
Low-Carb Version: Use keto-friendly buns or lettuce wraps instead of sandwich buns.
Honey-Spicy Twist: Mix a teaspoon of honey into the spicy mayo for a sweet heat balance.
Buffalo Style: Toss the cooked chicken in buffalo sauce instead of using sriracha mayo.

Serving Suggestions

Pair with air fryer French fries or sweet potato fries for a classic combo.
Serve alongside a crisp coleslaw for added freshness and texture contrast.
For meal prep, wrap sandwiches individually in parchment paper and refrigerate for up to 2 days; reheat in the air fryer to restore crispiness.
