Preheat and Prep: Preheat your oven to 410°F (210°C) and place a dark metal or cast-iron pan inside to heat up. A hot pan ensures immediate crisping.
Make the Egg Wash: In a bowl, whisk together the egg and buttermilk until smooth.
Prepare the Coating: In a separate bowl, mix flour, breadcrumbs, baking powder, salt, paprika, garlic powder, onion powder, and pepper.
Bread the Chicken: Dredge each chicken strip in the flour mixture. Dip into the egg mixture. Return to the flour mixture and coat again, pressing to adhere for maximum crunch.
Heat the Pan and Add Butter: Remove the hot pan from the oven and melt the butter in it. Arrange chicken strips in a single layer, leaving space between each.
Bake to Perfection: Bake for 10–12 minutes, flip the chicken, and bake for another 5–10 minutes until golden and cooked through. For extra crispiness, broil for 1–2 minutes at the end.
Rest and Serve: Let the chicken rest for 2–3 minutes before serving to keep juices sealed in.
