Instructions
Prepare to impress with this easy, step-by-step guide to making a perfect Air Fryer Blooming Onion.
- Prepare the Onion: Start by cutting off about 1/2 inch from the top of the large sweet onion. Peel off the papery outer skin completely.
- Make the Cuts: Place the onion cut-side down on a cutting board. Locate the root end. Starting about 1/2 inch from the root, make a downward cut all the way through to the board. Repeat this process to make four evenly spaced cuts around the onion. Then, make 3 additional cuts between each of these sections until you have 16 evenly spaced cuts. The root should remain intact to hold the petals together.
- Relax the Petals: Turn the onion over onto its cut side and let it rest for 5 minutes. This allows the onion petals to gently relax, making separation easier.
- Separate Gently: Before you begin breading, use your fingers to very gently separate the outer petals of the onion. Be careful not to break them off.
- Set Up Breading Stations: In a large bowl, whisk together the flour, paprika, cayenne, cumin, thyme, oregano, salt, and pepper. In a separate medium deep bowl, whisk the eggs, milk, and water until well combined.
- First Dry Coat: Place the onion in the clean large bowl with the dry flour mixture, cut-side up. Use a large spoon to generously coat the onion with the flour, ensuring it gets between all the petals. Turn the onion over and gently tap off any excess flour. Reserve the bowl of flour for the second coat.
- Wet Dip: Carefully transfer the floured onion into the egg mixture, ensuring it is fully submerged and coated evenly. Lift the onion, allowing any excess liquid to drip back into the bowl.
- Second Dry Coat: Immediately transfer the onion back into the reserved flour mixture. Coat the onion thoroughly again, making sure all wet spots are covered. Gently tap off the extra flour. You will have some flour left over in the bowl.
- Chill: Place the breaded onion in the refrigerator for at least 15-20 minutes. This chilling step is crucial for the coating to adhere properly during cooking.
- Preheat Air Fryer: Preheat your air fryer to 350°F (175°C) for 10 minutes.
- Prepare for Frying: Remove the chilled onion from the refrigerator. Spray the entire breaded surface generously with oil from your spray bottle. This helps create a golden, crispy crust.
- Transfer to Air Fryer: Create a sling from a sheet of aluminum foil. Carefully use this sling to transfer the onion, cut-side up, into the preheated air fryer basket.
- Air Fry: Set the air fryer timer for 25 minutes. During cooking, open the basket every 8-10 minutes to check on the onion. Spray the onion with cooking oil 2-3 more times throughout the process, especially if you see any dry or floury spots. This ensures even crisping. The ideal temperature for frying onions generally falls between 300-350°F (150-175°C) to ensure even caramelization.
- Finish and Season: After 25 minutes, the onion should be golden brown and crispy. Carefully remove the onion using the aluminum foil sling. Immediately season it with a pinch of salt and pepper to taste.
- Make the Sauce: While the onion cooks, whisk together all the ingredients for the blooming onion sauce in a small bowl until smooth.
- Serve: Serve your hot and crispy Air Fryer Blooming Onion immediately with the prepared dipping sauce.
Pro Tips & Troubleshooting
Achieve the best results with these handy tips for your Air Fryer Blooming Onion. Use a very sharp knife for cutting the onion; this ensures clean, precise cuts without tearing the petals. Take your time gently separating the onion petals to avoid breaking them before breading. Do not skip the chilling step; it allows the breading to set and adhere better, preventing it from falling off during cooking. Spray oil generously before and during air frying to ensure maximum crispiness and a beautiful golden-brown color. If you notice any dry or floury spots during cooking, spray those areas with a little more oil.
Finally, avoid overcrowding the air fryer basket; if your onion is too large, it might be better to deep-fry or use a larger air fryer model.
Serving, Storage, and Variations
Serve your impressive Air Fryer Blooming Onion immediately after cooking, while it is still warm and at its crispiest. The homemade blooming onion sauce provided in the recipe perfectly complements its savory flavor. You can also offer other favorite dips like classic ranch dressing, honey mustard, or even a tangy barbecue sauce. For a cheesy delight, serve with warm nacho cheese sauce.
Leftovers are best stored in an airtight container in the refrigerator for up to 2 days. To reheat, place the onion back in the air fryer at 325°F (160°C) for 5-7 minutes, or until warmed through and re-crisped. Avoid the microwave, as it will make the coating soggy.
Feel free to get creative with your seasonings! Add a pinch of garlic powder or onion powder to the flour mixture for extra savory depth. For a spicier kick, increase the cayenne pepper or add a dash of chili powder. You could also try a blend of Italian herbs for a different flavor profile.
