Step‑by‑Step Instructions for Crispy Air Fryer Blooming Onion
Step 1: Prep the Onion
Begin by slicing about 1/2 inch off the top of a sweet onion, ensuring the root remains intact for stability. Carefully make vertical cuts from the top down, about 1/4 inch apart, stopping 1/2 inch from the root to form fragrant petals. Gently pull apart the layers to create that beautiful blooming onion shape, taking care not to break any petals.
Step 2: Season the Flour
In a mixing bowl, combine all-purpose flour with your desired seasonings, such as paprika, cayenne, and garlic powder. Mix thoroughly until evenly distributed, creating a flavorful coating that enhances the taste of your crispy blooming onion. Set aside to ensure a satisfying crunch that everyone will enjoy.
Step 3: Coating Process
Using tongs, roll the prepared blooming onion in the seasoned flour until fully coated, making sure the flour adheres well. Next, dip the onion in a prepared egg wash for a few moments to bind the flour, then coat it again in the seasoned flour for a double layer. This step is crucial for achieving that extra crispy texture once cooked in the air fryer.
Step 4: Preheat Air Fryer
Now it’s time to prepare your air fryer! Set it to 375°F (190°C) and allow it to preheat for about 5 minutes. Preheating creates a perfect environment for your crispy blooming onion to cook evenly, ensuring it turns golden brown and maintains its delightful crunch throughout the cooking process.
Step 5: Cook the Onion
Carefully place the coated blooming onion into the air fryer basket, ensuring it is situated upright. Generously spray it with oil to achieve that enticing golden hue, then air fry for 12-15 minutes. Keep an eye on the onion, checking halfway through to gently separate any sticking petals for even cooking and to enhance its stunning presentation.
Step 6: Serving
Once the blooming onion is beautifully golden and crispy, remove it from the air fryer and let it cool for a minute. Serve your masterpiece with a variety of dipping sauces, such as ranch dressing or spicy mayo. This crispy air fryer blooming onion is now ready to impress at your next gathering, offering a delightful snack that everyone will love!

Expert Tips for the Best Blooming Onion
-
Choose the Right Onion: Use Vidalia or sweet onions for a milder flavor. Yellow onions are sharper and can overwhelm the dish, so choose wisely.
-
Double Coat for Crispiness: Ensure the blooming onion is double-coated with flour to achieve that satisfying crunch. The extra layer is your secret to a perfectly crispy blooming onion.
-
Moisten Before Coating: Make sure your onion is dry before coating it with seasoned flour. A wet onion can cause the flour to clump and not adhere properly.
-
Don’t Rush the Cook Time: Every air fryer can vary, so start checking at 10 minutes. Keep cooking until you reach that glorious golden brown color for the best blooming onion.
-
Spray Generously: Use oil spray liberally to enhance crispness. Skimping on the oil can lead to a soggy texture, so be generous in your application!
How to Store and Freeze Blooming Onion
Room Temperature: Keep uneaten blooming onion petals at room temperature for up to 2 hours to maintain freshness. Serve promptly after cooking for the best flavor.
Fridge: Store leftovers in an airtight container in the fridge for up to 2 days. This helps preserve the crispiness, although they may soften slightly.
Freezer: For longer storage, freeze the blooming onion after cooking. Wrap it tightly in plastic wrap followed by aluminum foil, and it can last up to 1 month.
Reheating: To restore the crispiness when ready to eat, reheat the blooming onion in the air fryer at 375°F (190°C) for about 5-7 minutes, until hot and crunchy again.

Crispy Air Fryer Blooming Onion Recipe FAQs
How do I pick the right onion for my blooming onion?
Absolutely! For the best flavor, choose a sweet onion like Vidalia. These onions provide a milder taste that complements the crispy coating. If you prefer a sharper flavor, yellow onions can work, but be cautious as their stronger taste could overpower the dish.
How should I store leftovers of the blooming onion?
Leftover blooming onion petals can be stored in an airtight container in the fridge for up to 2 days. While they might lose some of their crispiness, you can easily restore it by reheating them in the air fryer at 375°F (190°C) for about 5-7 minutes.
Can I freeze my blooming onion?
Yes, you can! After cooking, let your blooming onion cool completely. Then, wrap it tightly in plastic wrap, followed by aluminum foil, to prevent freezer burn. It can be frozen for up to 1 month. Reheat in the air fryer when you’re ready to enjoy it again!
What can I do if my blooming onion petals stick together during cooking?
No worries! If you find the petals sticking together, carefully check the onion halfway through cooking and gently separate any stuck petals using tongs. This helps ensure an even cook and maintains the beautiful presentation of your blooming onion.
Are there any dietary considerations I should keep in mind?
Definitely! If you’re catering to dietary restrictions, you can use a gluten-free flour blend in place of all-purpose flour for gluten-sensitive individuals. For vegans, substitute the eggs with a flaxseed mixture (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water, let it sit until gelatinous) which works well as an egg replacer.
How long will my blooming onion stay fresh?
Your blooming onion will stay fresh at room temperature for up to 2 hours after cooking. Be sure to serve it promptly for the best taste, so your guests can enjoy that glorious crunch and flavor!
