Instructions

Make Alabama White BBQ Sauce

In a bowl, combine mayonnaise, apple cider vinegar, Dijon mustard, lemon juice, honey, garlic powder, black pepper, salt, and horseradish.

Whisk until smooth and creamy.

Cover and refrigerate for at least 30 minutes to allow the flavors to blend.

Prepare Caramelized Onions

Heat butter and olive oil in a skillet over medium-low heat.

Add sliced onions and salt. Cook slowly for 20–25 minutes, stirring occasionally, until the onions become soft, golden brown, and sweet.

Add brown sugar and balsamic vinegar during the last few minutes for extra depth of flavor.

Remove from heat and set aside.

Season the Chicken

Pat chicken dry with paper towels.

Brush chicken with olive oil.

Mix smoked paprika, garlic powder, onion powder, brown sugar, salt, black pepper, chili powder, and cayenne pepper in a small bowl.

Coat the chicken evenly with the seasoning mixture.

Let it rest for 10 minutes for better flavor.

Air Fry the BBQ Chicken

Preheat air fryer to 375°F (190°C) for 3 minutes.

Place chicken in the air fryer basket in a single layer.

Cook for:

Chicken breasts: 16–20 minutes

Chicken thighs: 14–18 minutes

Flip halfway through cooking.

Brush BBQ sauce over the chicken during the last 3–4 minutes.

Cook until the internal temperature reaches 165°F (74°C).

Let the chicken rest for 5 minutes, then slice.

Assemble the Sandwiches

Lightly toast the buns in the air fryer for 1–2 minutes.

Spread Alabama white BBQ sauce on the bottom bun.

Add lettuce, sliced BBQ chicken, caramelized onions, and pickles.

Drizzle with extra white BBQ sauce.

Cover with the top bun and serve warm.

Tips for Perfect BBQ Chicken Sandwiches

Use chicken thighs for extra juicy and tender meat.

Do not overcrowd the air fryer basket; cook in batches if needed.

Let the chicken rest before slicing to keep it juicy.

Cook mushrooms? (No — avoid adding extra moisture ingredients because this sandwich is designed for BBQ flavor.)

Make the Alabama white sauce ahead of time for the best flavor.

Toasting the buns prevents them from becoming soggy.

Storage
