How to Make Crispy Air Fryer Blooming Onion
Ready to transform a simple onion into a show-stopping appetizer? Follow these easy steps, and you’ll be amazed at how simple it is to make a crispy blooming onion in your air fryer. We’re going for that perfect golden-brown exterior and tender, separated petals!
- Step 1: First things first, preheat your air fryer to 375°F (190°C). This is crucial for getting that beautiful, even crispiness we’re after.
- Step 2: Grab your large sweet onion. Peel off the outer skin and trim off the very top, but be sure to leave the root end completely intact – it’s the glue that holds your blooming onion together! Make four deep cuts from the top, stopping about half an inch from the root. Then, make three more cuts between each of those to create 16 “petals.” Gently spread these layers apart with your fingers.
- Step 3: In a medium bowl, whisk together the 2 large eggs and ½ cup unsweetened almond milk until well combined. This is our wet mixture.
- Step 4: In a large bowl, combine the 1 cup oat flour, ½ cup cornmeal, ½ teaspoon paprika, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon salt, and ½ teaspoon black pepper. Mix this dry coating well.
- Step 5: Now, carefully dip the prepared onion upside down into the egg mixture. Use your hands to gently separate the petals and make sure the liquid gets all the way down. Let any excess drip off.
- Step 6: Transfer the wet onion to the bowl with the dry coating. Press the flour mixture firmly onto all sides, really getting it down between the petals. For an extra thick, crunchy crust, you can repeat the dip-and-coat process. This step is key to achieving that perfect air fryer blooming onion coating.
- Step 7: Give the coated onion a generous coating of olive oil spray all over. This is essential for that golden-brown, crispy finish.
- Step 8: Carefully place the onion, root-side down, into your preheated air fryer basket. You might need to use a piece of foil folded into a ring to help it stand upright if it’s wobbly. This ensures a stable base for even cooking – a vital part of how to make crispy blooming onion in air fryer.
- Step 9: Air fry for 20–25 minutes. About halfway through, you might want to rotate the onion for even browning. Keep an eye on it until it’s deeply golden brown and looks wonderfully crispy. Getting the right air fryer blooming onion cooking time ensures perfection!
- Step 10: Once beautifully golden and crispy, carefully remove the onion from the air fryer. Let it cool for a few minutes before serving hot with your favorite dipping sauce. Enjoy your homemade masterpiece!
Preparing the Onion
To get that signature bloom, carefully cut the onion from the top down to ½ inch above the root, creating four deep sections, then three more between each. Gently fan out the layers. For maximum blooming onion air fryer success, chilling the cut onion for 30 minutes can help it hold its shape better during coating.

Coating the Onion
Dip the onion into the egg wash, ensuring the liquid gets between every petal. Then, press it into the seasoned flour and cornmeal mixture. This double-dip method creates a fantastic air fryer blooming onion coating that gets wonderfully crisp when cooked.
Air Frying the Blooming Onion
Place your coated onion in the air fryer basket, root-side down. Cook at 375°F (190°C) for 20–25 minutes, rotating as needed. Achieving the correct air fryer blooming onion cooking time is key for that perfect deep golden color and crispy texture.

How to Store and Reheat Air Fryer Blooming Onion
I know how tempting it is to devour this entire appetizer in one sitting, but if you happen to have leftovers, knowing how to properly store and reheat your air fryer blooming onion is key to enjoying them later. The goal is to bring back that glorious crispiness!
Once your blooming onion has cooled completely, store any leftovers in an airtight container or wrap it tightly in foil. It should stay good in the refrigerator for about 3 to 4 days. For longer storage-related secondary keyword preservation, you can freeze the cooked onion. Wrap it well in plastic wrap, then in foil, and it should last up to 3 months in the freezer.
Reheating is where the magic happens to revive that crunch. Skip the microwave, as it makes things soggy! Instead, pop your leftover blooming onion back into the air fryer at 350°F (175°C) for about 5–8 minutes, or until it’s heated through and delightfully crispy again. You can also use a toaster oven or a regular oven at the same temperature for a similar effect. For more air fryer tips, explore our latest recipes.
Frequently Asked Questions About Crispy Air Fryer Blooming Onion
Can I use regular all-purpose flour instead of oat flour?
Yes, you absolutely can! While I love the subtle flavor and texture oat flour brings to this easy air fryer blooming onion, all-purpose flour works just fine. Just ensure you still mix it with the cornmeal and seasonings for that signature crunch. You might find the crust to be slightly different, but still delicious!
What’s the best dipping sauce for an air fryer blooming onion?
Oh, this is my favorite part! My go-to is a simple homemade “blooming sauce” made with mayonnaise, ketchup, horseradish, and a little paprika. It’s the classic pairing for a reason! You can also try a spicy sriracha mayo, a zesty ranch, or even a garlic aioli. The possibilities for an amazing easy air fryer blooming onion experience are endless!
My blooming onion didn’t get crispy. What went wrong?
Don’t worry if your first attempt isn’t perfectly crispy! There are a few common culprits. Make sure you’re spraying the onion thoroughly with olive oil spray before air frying – this is crucial for crisping. Also, ensure you’re not overcrowding the air fryer basket; give it plenty of space for the air to circulate. Finally, check that your air fryer is preheated properly to the correct temperature.
Can I make a gluten-free or vegan version?
Absolutely! For a gluten-free option, simply use certified gluten-free oat flour and cornmeal. To make it vegan, replace the eggs with a flax egg (1 tablespoon flaxseed meal whisked with 3 tablespoons water, let sit for 5 minutes) and ensure your milk alternative is plant-based. This makes for a wonderfully inclusive and easy air fryer blooming onion for everyone to enjoy!
Variations of Air Fryer Blooming Onion You Can Try
While the classic recipe is amazing, don’t be afraid to get creative with your air fryer blooming onion! I love experimenting with different flavors and dietary needs to make this appetizer accessible and exciting for everyone.
