Start by peeling the large sweet onion and cutting off the top and root ends. Be sure to leave the root end intact; it's crucial for keeping the onion together during the cooking process. Place the onion with the flat, cut side down.
In a bowl, combine 1 ½ cups of all-purpose flour with 1 tablespoon of paprika, ½ teaspoon of ground cumin, ½ teaspoon of dried thyme, and ½ teaspoon of dried oregano. Mix these dry ingredients thoroughly.
In another bowl, whisk 2 large eggs with ½ cup of water to create an egg wash.
Take your prepared onion and carefully start to separate the layers, but be sure not to cut through the root end. You want the onion to resemble a blooming flower.
Once your onion is blooming, dip it into the dry flour mixture, making sure to get the flour into all the nooks and crannies of the onion. Shake off any excess flour.
Next, dip the onion into the egg wash, ensuring it's well-coated. Once again, let any excess drip off.
Now, return the onion to the flour mixture for a second coating. This will help create that deliciously crispy exterior we all love.
Place your beautifully coated bloomin' onion into the basket of your air fryer. Lightly spray it with avocado oil to help achieve that perfect golden brown finish.
Set your air fryer to 350°F (175°C) and cook for approximately 25 minutes. During the cooking process, give it a couple more spritzes of avocado oil. This will help achieve that mouthwatering crispiness that's a hallmark of a good bloomin' onion.
To create the sauce mix equal parts of mayo and Primal Kitchen BBQ sauce in a bowl.
Once your Air Fried Bloomin' Onion is beautifully golden and crispy, carefully remove it from the air fryer. Place it on a serving plate and let it cool slightly.
