How to Make Crispy Air Fryer Blooming Onion
Prepare the Onion: Start by cutting off about 1/2 inch from the top of the large sweet onion, and then peel it carefully. Make 12-16 vertical cuts, stopping just above the root to keep the petals together. Gently separate the petals to create the bloom.
Soak: Place the onion in a bowl of ice water for about 30 minutes. This step is essential, as it helps the layers open up beautifully, enhancing both the bloom effect and crispiness.
Mix Coatings: In one bowl, whisk together the all-purpose flour, paprika, garlic powder, onion powder, salt, black pepper, and optional cayenne. In a separate bowl, whisk the eggs and milk together until well combined.
Bread the Onion: After soaking, pat the onion dry using paper towels. First, dip it into the flour mixture, making sure to coat it entirely. Then, dip into the egg wash, allowing any excess to drip off. Finally, return it to the flour for a second coating, ensuring a thick, crispy layer.
Air Fry: Lightly spray the coated onion with cooking spray, then place it into the air fryer basket. Cook at 375 °F (190 °C) for 20-25 minutes until it s golden brown and crispy. Don’t forget to spray it again halfway through cooking for even crispness!
Serve: In the meantime, mix together your dipping sauce ingredients. Once the onion is done cooking, let it cool slightly before serving warm with the zesty sauce.
Optional: Add a sprinkle of fresh parsley for a pop of color before serving.
