Cut the pointed top end from the onion. Peel. Place, cut side down, on a board and make 10 cuts, from the top to about 1cm from the base. Gently loosen onion segments to make ‘petals’.
Whisk the egg and milk in a jug. Combine flour, paprika, garlic powder and onion powder in a small bowl. Place onion in a bowl and sift over some flour mixture, filling any gaps. Shake off excess and reserve. Drizzle egg mixture over the onion and into the gaps. Sprinkle with remaining flour mixture. Spray with olive oil. Cook in an air fryer at 180C, spraying with oil halfway through, for 15 minutes or until golden and crisp. Serve with sweet chilli sauce, sour cream and chives.
