Ingredients:

  • 1 colossal yellow onion
  • 1.5 cups all-purpose flour
  • 2 tsp cornstarch
  • 2 tsp smoked paprika
  • 1 tsp garlic powder
  • 1 tsp dried oregano
  • 0.5 tsp cayenne pepper
  • 1 tsp kosher salt
  • 2 large eggs
  • 0.5 cup buttermilk
  • 1 tbsp olive oil (via mister/spritzer)
  • 0.5 cup plain Greek yogurt
  • 2 tbsp horseradish
  • 1 tbsp ketchup
  • 1 tsp Cajun seasoning

Instructions:

  1. Slice off the top (non-root end) of the onion and peel the outer skin. Place the onion flat-side down and make 4 vertical cuts, leaving 1/2 inch at the root intact. Continue making cuts between quarters until you have 16 even petals.
  2. Submerge the onion in an ice water bath for 10 minutes to draw out sulfur compounds and hydrate the petals. Pat dry thoroughly before breading.
  3. Whisk together the flour, cornstarch, smoked paprika, garlic powder, oregano, cayenne, and salt in a large bowl. In a separate bowl, whisk the eggs and buttermilk.
  4. Dredge the onion in the flour mixture, ensuring all petals are coated. Dip into the buttermilk mixture, then back into the flour for a double-dredge bond.
  5. Preheat the air fryer to 375°F. Generously mist the onion with olive oil using a refillable spritzer.
  6. Air fry for 25 minutes. Use a foil buffer midway through cooking to protect the delicate tips from burning if necessary.
  7. Mix the Greek yogurt, horseradish, ketchup, and Cajun seasoning to create the dipping sauce and serve immediately.
