Step 1

Whisk together 1/2 cup  buttermilk and 1 tablespoon ranch seasoning in a medium bowl. Add the chicken, cover and refrigerate for up to 24 hours, if time allows, or use immediately.

Step 2

Whisk together the flour, cornstarch and 4 tablespoons ranch seasoning in a separate medium bowl. Pour in 3 tablespoons of the buttermilk marinade and mix with a fork to form small lumps throughout.

Step 3

Preheat a 6-quart air fryer to 380 degrees F. Remove the chicken from the marinade and dredge in the flour mixture, pressing to adhere and lightly shaking off the excess. Place on a baking sheet lined with a wire rack. Generously spray all sides of the chicken with olive oil cooking spray and place half of the chicken in the preheated air fryer basket. Fry the chicken in two batches until the chicken is cooked through, crisp and golden, about 7 minutes per side. When the chicken is done, remove from the air fryer and chop into bite sized pieces.

Step 4

Meanwhile, whisk the mayonnaise, sour cream, remaining 3 tablespoons buttermilk, remaining 1 tablespoon ranch seasoning, parsley, chives, dill and 1/2 teaspoon each salt and pepper together in a large bowl. Add the carrot ribbons, cucumbers, tomatoes, avocado and lettuce and toss to combine.

Step 5

Divide the salad among plates and top with the chicken.
