Ingredients
  

Onion Preparation
  • 4 small small onions Make sure the onions are small; they will bloom better.
Breading Mixture
  • 1 cup all-purpose flour
  • 1 teaspoon paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • ½ teaspoon black pepper
Wet Mixture
  • 2 large eggs
  • 1 cup buttermilk If you don’t have buttermilk, mix regular milk with a tablespoon of lemon juice or vinegar.
Final Coating
  • 1 cup breadcrumbs Use fine breadcrumbs for even coating.
  • Cooking spray For air frying.

Method
 

Preparation
  1. Trim the top of each onion and peel. Cut into 8–10 thin petals, leaving the root intact so the onion holds together.
  2. Shake the onion gently to fan the petals.
  3. Whisk flour, paprika, garlic powder, salt, and pepper in a shallow bowl.
  4. Beat eggs with buttermilk in another bowl until smooth.
  5. Place breadcrumbs in a third bowl.
Breading the Onions
  1. Dredge each onion in the flour mix, tapping off excess.
  2. Dip in the egg-buttermilk mix so it seeps between petals.
  3. Press breadcrumbs onto the petals to coat well. Repeat the egg and breadcrumb step for a thicker crust if desired.
Cooking
  1. Preheat the air fryer to 375°F (190°C). Spray the basket lightly with cooking spray.
  2. Place onions in the basket, petals up, spacing them so hot air can circulate. Spray the tops with cooking spray.
  3. Cook for 10–12 minutes until golden and crisp; you’ll hear a soft crackle and see deep golden edges.
  4. Let rest for 2 minutes before serving.

Notes

Optional: Serve with a simple dipping sauce of mayo, lemon juice, and a pinch of paprika. Time-saver: Prep and bread all onions at once, then air-fry in batches to save time. Variation: Add cayenne for heat or try a sweet dip like Oreo fudge for dessert contrast.
