The air fryer blooming onion is a stunning and tasty appetizer that’s sure to impress. While creating this recipe, I went through a few trial-and-error attempts, which I discuss below. This version uses no egg mixture, and skips the mess of deep frying. Inspired by the iconic Outback Steakhouse appetizer, this homemade version brings out the ‘oohs’ and ‘ahs’ without the guilt.

Instructions
Peel the onion and cut off the top.
Place cut side down on to a cutting board. Cut downward, from the center outward, all the way to the cutting board. Repeat, making eight evenly spaced cuts around the onion. Make sure knife slices all the way through all of the layers. Leave onion connected in the center.
Carefully, place the onion in ice water for at least two hours.
Mix all of the ingredients in a small bowl.
After soaking onion in cold water, remove and dry. I place mine on an elevated mesh plate and then use a paper towel to pat dry.
Preheat air fryer to 400-degrees Fahrenheit.
Add water to spice mixture to make a batter and whisk well to get rid of lumps.
NOw coat the onion with the batter. Spread the layers out and make sure they are covered on the inside. I use a slotted spoon under the onion so I can lift easily when I am done.
Move battered onion to a small bowl with bread crumbs and set onion on top to coat bottom of onion with bread crumbs.
Lightly coat the top of the onion with bread crumbs.
Spray onion with cooking spray.
Move onion to the air fryer, cut side up.
Cook at 400-degrees F for 10 minutes, then cook 15-minutes at 350-degrees F.
