Tips for Cutting The Onion for A Blooming Onion

Cut off ½ inch from the top of the onion, then peel off the outer skin. Position the onion cut-side down on a flat kitchen board.

Start by cutting ½ inch from the root in a downward direction until you reach the board, then repeat to achieve four evenly spaced cuts around the entire onion.

Make three cuts between each section, for a total of 16 cuts. Turn the onion over and let it sit for 5 minutes so the petals relax. You’re going to gently separate the outer pieces of the onion with your fingers just before breading.

Breading The Onion

Whisk together the flour, paprika, cayenne, cumin, thyme, and oregano in a large bowl. Whisk the eggs, milk, and 1 cup of water in a separate medium bowl with depth.

Add the onion to a clean bowl with the cut side upwards and pour the dry mixture on top. Use a large spoon to coat the onion, paying particular attention to the onion petals. Turn the onion over and gently pat off any excess flour. Reserve the bowl of flour.

Place the onion in the egg mixture and coat it evenly. Remove the onion and allow any excess mixture to drip off before transferring it back to the reserved flour mixture, then repeat the entire process.

Air Fry Onion

Remove the onion from the fridge and spray it generously with cooking oil. Make a sling from aluminum foil to transfer the onion, cut-side up, into the air fryer basket. Cook the onion for 25 minutes, spraying it with oil 2-3 times as it cooks.

Remove the onion from the air fryer with the help of the foil sling and season it. Enjoy your air fryer blooming onion with dip!

Tips & Tricks

• Choose the right onion – Sweet onions like Vidalia work best for blooming onions because they’re mild, tender, and open easily when cut.
• Use a sharp knife – Clean cuts help the onion bloom properly and reduce tearing while cutting.
• Let the onion rest after cutting – Allowing it to sit for 5 minutes helps the petals relax and separate more easily.
• Don’t skip the oil spray – Light, even sprays of oil are key to getting that crispy, golden coating in the air fryer.
• Spray in stages – Re-spray the onion 2–3 times during cooking for maximum crunch.
• Chill before air frying – Refrigerating the breaded onion helps the coating stick and crisp better.
• Customize the seasoning – Swap or add spices like chili powder, smoked paprika, or garlic powder to change the flavor profile.
• Prevent watery eyes – Chill the onion in the freezer for 10–15 minutes before cutting to reduce eye irritation.

Onion to Use

• Sweet onions (Vidalia) = best flavor + bloom
• Yellow onions = okay backup
• Avoid red onions (too firm, uneven cook)

Air Fry Time May Vary

• Basket-style air fryers tend to have longer cooking times than oven-style air fryers.
• Check at 20 minutes, and if you feel it needs longer, cook for another 5-10 minute increments.
• Larger onions may need extra time as there is a lot more onion to cook.

Seasoning Variations

Here are a few ways to change up the flavor of your blooming onion! Get creative and try your usual spices and seasonings to create your own flavoring mixture.

• Spicy (extra cayenne or chili powder)
• Smoky (smoked paprika)
• Ranch-style (ranch seasoning mix)
• Creole seasoning would be and add a nice spice factor
