Step 1: Prepare the Onion
- Peel and Slice: Peel the onion and cut off the top, leaving the root end intact. Place the onion cut-side down on a cutting board. Make 8-12 evenly spaced cuts from the root end to the top, being careful not to cut all the way through.
- Bloom the Onion: Gently separate the onion petals by gently pulling them apart. This will create the “bloom” effect.
Step 2: Prepare the Breading Station
- Mix Flour and Spices: In a large bowl, whisk together the flour, paprika, garlic powder, onion powder, oregano, thyme, salt, and black pepper.
- Prepare Wet Ingredients: In another bowl, whisk together the eggs and buttermilk.
- Prepare Breadcrumbs: Place the panko breadcrumbs in a third bowl.
Step 3: Bread the Onion
- Coat in Flour Mixture: Carefully coat the onion in the flour mixture, making sure to get the mixture between the petals. Shake off any excess flour.
- Dip in Egg Mixture: Dip the flour-coated onion into the egg mixture, making sure to cover all the petals.
- Coat with Breadcrumbs: Coat the onion with panko breadcrumbs, pressing gently to ensure the crumbs stick well.
Step 4: Air Fry the Onion
- Preheat Air Fryer: Preheat your air fryer to 400°F (200°C) for about 5 minutes.
- Prepare for Air Frying: Lightly spray the air fryer basket with cooking spray to prevent sticking.
- Air Fry: Place the breaded onion in the air fryer basket. Cook at 400°F (200°C) for 15-20 minutes, or until the onion is golden brown and crispy. You may need to check halfway through and gently shake the basket to ensure even cooking.
Step 5: Prepare the Dipping Sauce
- Mix Ingredients: In a small bowl, combine the mayonnaise, ketchup, horseradish, hot sauce (if using), paprika, garlic powder, and onion powder. Stir until well combined.
- Chill: Refrigerate the dipping sauce until ready to serve.
Step 6: Serve
- Cool Slightly: Allow the blooming onion to cool slightly before serving.
- Garnish: Place the onion on a serving platter and serve with the dipping sauce on the side.
Tips and Variations
- Extra Crispy: For extra crispy results, lightly spray the breaded onion with cooking spray before air frying.
- Seasoning Variations: Experiment with different seasonings or add a bit of cayenne pepper for some heat.
- Make Ahead: You can prepare and bread the onion ahead of time and freeze it. Cook from frozen, adding a few extra minutes to the cooking time.
