Step‑by‑Step Instructions for Air Fryer Blooming Onion
Step 1: Prep the Onion
Begin by cutting about ½ inch off the top of your sweet onion, exposing the layers inside. Carefully make vertical cuts about ¼ inch apart, starting from the top and working down towards the root, ensuring you don’t cut through the base. This will create a beautiful blooming effect when cooked.
Step 2: Coat in Flour
Place your seasoned all-purpose flour in a shallow dish. Gently roll the prepared onion in the flour, making sure to coat each petal thoroughly, getting flour in between the layers for maximum crunch. This foundational step is key for that crispy texture in your Air Fryer Blooming Onion.
Step 3: Create Egg Wash
In a separate bowl, whisk together eggs to create your egg wash. Take the floured onion and dip it into the egg wash, letting any excess drip off back into the bowl. This step ensures the second coating sticks perfectly, giving your onion that alluring crispy outer layer.
Step 4: Double-Dip for Extra Crunch
Return the onion to the shallow dish of seasoned flour for a second coating. Gently shake off any excess flour after covering the onion again. This double-dipping method will guarantee a thicker crunch that beautifully holds up in the air fryer!
Step 5: Preheat the Air Fryer
Start by preheating your air fryer to 375°F (190°C) while you finish prepping the onion. This preheating ensures your Air Fryer Blooming Onion will cook evenly and develop that delightful golden-crisp exterior. The scent of the heating air fryer will get you excited for the delicious appetizer ahead!
Step 6: Air Fry and Crisp
Spray the coated onion generously with your oil spray to encourage that perfect crispiness. Carefully place the onion in the air fryer basket and fry for about 12-15 minutes, checking periodically. You want to achieve a stunning golden-brown coloration and a crunchy texture on those lovely petals.
Step 7: Check and Separate Petals
Halfway through the air frying, stop the machine and check on your onion. Use tongs to gently separate any petals that may be sticking together, ensuring even cooking and crispness. This step will help maintain that visually striking bloom and enhance the overall texture when served.

Storage Tips for Air Fryer Blooming Onion
Fridge: Store any leftover Air Fryer Blooming Onion petals in an airtight container for up to 2 days. This will help preserve their flavor and texture.
Freezer: For longer storage, freeze the uneaten onion petals wrapped in plastic wrap and then placed in a freezer bag for up to 3 months.
Reheating: To re-crisp frozen onion petals, air fry them at 350°F for 3-5 minutes until they regain their crunchy texture.
Avoid Moisture: Ensure the container or wrapping is airtight to prevent moisture from softening the crispy petals.
Make Ahead Options
Preparing your Crispy Air Fryer Blooming Onion ahead of time is a fantastic way to save precious minutes on busy weeknights or during gatherings! You can prep the onion by cutting and coating it in the flour mixture up to 24 hours in advance; simply wrap it tightly in plastic wrap to prevent browning. For the best results, keep the battered onion in the refrigerator until you’re ready to cook it. When it’s time to serve, just dip it in the egg wash, double-dip in flour, and air fry as per the original instructions for that crispy, golden perfection, ensuring a delightful appetizer that’s just as delicious as if made fresh!
