Method: Crispy Air Fryer Blooming Onion

Step 1: Prepare the Onions
Start by peeling the two large sweet onions. Cut off the top of each onion, leaving the root intact. Place the onion cut-side down on a cutting board, and slice it into petals. Make cuts around the onion, about 1/4 inch apart, going down about three-quarters of the way to the root. Gently pull apart the petals to create the blooming effect.
Step 2: Make the Batter
In a large mixing bowl, whisk together the all-purpose flour, garlic powder, onion powder, smoked paprika, Italian seasoning, Ranch powder, salt, chili powder, and black pepper. In another bowl, combine the milk, egg, and melted butter.
Step 3: Coat the Onion
Dip each onion into the flour mixture, ensuring it’s thoroughly coated. Then, dip it into the milk mixture, allowing any excess to drip off before returning it to the flour mixture for a final coating. Ensure that the onion is well coated for maximum crunch.
Step 4: Prepare for Air Frying
Place the coated onion on a plate or baking sheet. Sprinkle the Panko bread crumbs generously over the onion, pressing them down gently to adhere. Lightly spritz the onion with oil spray to enhance the crisping process during cooking.
Step 5: Air Fry the Onion
Preheat your air fryer to 375°F (190°C). Once heated, place the blooming onion in the air fryer basket, ensuring it’s not overcrowded. Cook for approximately 15-20 minutes, or until the onion is golden brown and crispy. You may want to check halfway through and spritz with a bit more oil for an extra crunch.
Step 6: Serve and Enjoy
Once cooked, carefully remove the blooming onion from the air fryer. Allow it to cool for a minute before serving with your favorite dipping sauce. Enjoy the crispy, savory goodness of your Crispy Air Fryer Blooming Onion!
Season-by-Season Upgrades

- Spring: Add fresh herbs like chives or parsley to brighten the flavor.
- Summer: Serve with a zesty avocado-lime dip for a refreshing twist.
- Fall: Incorporate pumpkin spice into the flour mixture for a seasonal flair.
- Winter: Pair it with a warm cheese dip for a cozy treat.
Mistakes Even Pros Make
- Not Cutting Deep Enough: Ensure your cuts are deep enough; otherwise, the onion won’t bloom properly.
- Overcrowding the Air Fryer: Give each onion room to breathe for even cooking.
- Skipping the Oil Spray: A light coat of oil is essential for achieving that desired crispiness.
- Not Using Fresh Spices: Old spices can dull the flavors; always use fresh for the best results.
Shelf Life & Storage
The Crispy Air Fryer Blooming Onion is best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. To reheat, place them back in the air fryer for a few minutes to regain their crispiness.
