Optional Marinade: Pat chicken tenders with paper towel, trim fat, and remove tendons (try this easy hack!). Place tenders in a large container or bag, pour buttermilk over, and seal. Marinate in the fridge for 20–30 minutes (or up to overnight). Discard leftover buttermilk and pat tenders dry with paper towel.
Whisk together 2 tablespoons mayo and the remaining “Chicken Batter” ingredients in a shallow bowl. In a second shallow bowl, Stir all “Chicken Breading” ingredients together. Use tongs to coat all tenders in batter, then dredge them generously in breading. Generously spray one side of tenders with cooking spray.
Air Fryer Instructions: Set air fryer to 400°F. Place tenders in a single layer in the basket (cook in batches if needed). Cook for 5–8 minutes, flip, spray other side, and cook another 5–8 minutes until golden brown and internal temperature reaches 160°F (carryover heat will bring it to 165°F). Check smaller tenders sooner to avoid overcooking.
Oven Instructions: Preheat oven to 400°F. Generously grease a baking pan with cooking spray. Place breaded, sprayed tenders on pan. Bake for 10 minutes, flip tenders, spray the other sides, and bake for 7–10 more minutes or until internal temperature reaches 160°F.
Combine mayo with all “Dipping Sauce” ingredients, adding salt and pepper to taste. Whisk and adjust seasonings as desired.
Serve tenders hot with sauce for dipping! These don’t stay crispy when stored, so I recommend breading and cooking only enough for one meal.

Notes
Note 1: One pound of tenderloins is about 6–8 pieces. You can also cut chicken breasts into 3/4-inch thick strips.Note 2: Panko bread crumbs are similar to regular bread crumbs, but they create a much crunchier result. They can be found near breadcrumbs, flour, or cornmeal in the grocery store.Storage: Best eaten right out of the air fryer; they lose crispiness quickly!
