Combine the flour, garlic powder, paprika, 1/2-1 tsp salt and a few cracks of freshly ground black pepper on a plate. Tip the beaten egg onto another plate and the breadcrumbs onto a third.

Toss the chicken pieces in the flour mix, then the egg, and finally the breadcrumbs. Set aside on a tray. Heat the air-fryer to 200C, then cook the chicken nuggets in a single layer (you may need to do this in batches) for 10-12 mins until cooked through and golden brown. Serve with ketchup, if you like.
