- 1 large sweet onion
- 2 ½ cups all-purpose flour
- 1 tablespoon paprika

- 2 large eggs
- 1 cup milk

How to Make Air Fryer Blooming Onion
Step 1: Prepare the Onion
Start by slicing the onion for blooming. Cut off about 1/2 inch from the top of the onion and peel away the outer skin.
Step 2: Make Cuts for Blooming
Place the onion cut-side down on the cutting board.
Starting about 1/2 inch from the root:
1. Make a downward cut all the way through to the cutting board.
2. Repeat this around four times, ensuring even spacing.
3. Add three more cuts between each section until you have 16 evenly spaced cuts.
Step 3: Relaxing Petals
Turn the onion over and let it sit for about five minutes so that the petals can relax.
Step 4: Separate Outer Pieces
Gently use your fingers to separate out the outer pieces of each petal before breading.
Step 5: Prepare Breading Mixture
In a large bowl, whisk together:
2 ½ cups all-purpose flour
1 tablespoon paprika
1 teaspoon cayenne pepper
½ teaspoon ground cumin
½ teaspoon dried thyme
½ teaspoon dried oregano
Salt and pepper
In a medium-sized bowl, whisk together:
2 large eggs
1 cup milk
1 cup water
Step 6: Coat Onion with Flour Mixture
Place the prepared onion cut-side up in a clean bowl.
Pour some of the flour mixture over it.
Use a large spoon to coat thoroughly, especially between petals.
Turn over gently and remove excess flour.
Step 7: Dip in Egg Mixture
Transfer the coated onion into the egg mixture.
Ensure it’s evenly coated before letting excess drip off.
Step 8: Re-coat with Flour
Return it back into the reserved flour mixture and repeat the coating process, tapping off any extra flour if needed.
Step 9: Chill Before Cooking
Put the prepared onion in the refrigerator while you preheat your air fryer.
Step 10: Preheat Air Fryer
Preheat your air fryer at 350ºF for about ten minutes.
Step 11: Spray Onion with Oil
Take out your chilled onion from refrigeration and spray generously with vegetable oil using a spray bottle.
Step 12: Prepare for Cooking
Using aluminum foil, create a sling and transfer your coated onion cut side up into the fryer basket.
Step 13: Cooking Time
Set your timer for 25 minutes. During cooking, spray oil onto any visible flour spots on the onion 2–3 times.
Step 14: Finish Off
After cooking time is complete, carefully remove your blooming onion using aluminum foil sling. Season with salt and pepper to taste before serving with dip.

Common Mistakes to Avoid

Skipping the onion prep: Properly slicing the onion is crucial for it to bloom. Make careful cuts and separate the petals gently to ensure even cooking.
-
Not seasoning adequately: Don’t underestimate the importance of seasoning. Make sure to season both the flour mixture and the finished onion for maximum flavor.
-
Using too much or too little oil: Balance is key! Too much oil can make it greasy, while too little can lead to dryness. Lightly spray oil on all sides before air frying.

-
Ignoring cooking times: Every air fryer is different. Keep an eye on your onion and adjust cooking times as necessary for perfect crispiness.
