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:
- 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.
- 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.
- 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.
- 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.
- Preheat the air fryer to 375°F. Generously mist the onion with olive oil using a refillable spritzer.
- Air fry for 25 minutes. Use a foil buffer midway through cooking to protect the delicate tips from burning if necessary.
- Mix the Greek yogurt, horseradish, ketchup, and Cajun seasoning to create the dipping sauce and serve immediately.
