Step‑by‑Step Instructions for Crispy Air Fryer Blooming Onion
Step 1: Prepare the Onion
Start by cutting about 1/2 inch off the top of a sweet onion, but be sure to leave the root intact for support. Next, make vertical cuts around the onion, spaced approximately 1/4 inch apart—these will create the delicate petals. As you work, flip the onion upside down and gently separate the layers to open it up fully, revealing a stunning flower shape.
Step 2: Coat the Onion
In a shallow bowl, combine all-purpose flour with your desired seasonings, including optional cayenne pepper for a kick. Carefully roll the opened onion in the seasoned flour mixture, ensuring it gets between all the petals. Once well-coated, dip the onion into an egg wash, letting any excess drip off, and then return it to the flour for a final coating—this creates that irresistible crispy layer.
Step 3: Preheat Air Fryer
Before air frying, preheat your air fryer to 375°F (190°C). This helps achieve that perfect golden crunch on the outside while keeping the inside tender. While the air fryer heats up, lightly spray the coated onion with oil to ensure an even crisp during cooking. The oil spray is crucial for mimicking the fry texture of classic blooming onions.
Step 4: Air Fry
Carefully place the coated onion in the preheated air fryer basket. It’s important not to overcrowd the basket to allow for proper airflow. Air fry the onion for 12-15 minutes, or until it’s beautifully golden brown and crispy. Keep an eye on it as it cooks—the layers should look inviting and crunchy while the petals gently separate.
Step 5: Check for Crispness
At the halfway mark, around 6-7 minutes into cooking, pause the air fryer and check the onion. Gently separate any petals that may be sticking together to ensure even cooking. If needed, you can also give it a quick spray of oil to add extra crispiness. After this check, resume cooking until it reaches that delicious, golden perfection.
Step 6: Serve and Enjoy
Once your crispy air fryer blooming onion is done cooking, carefully remove it from the air fryer. Allow it to cool for a minute before serving. This impressive appetizer pairs wonderfully with creamy ranch or spicy mayo for dipping. Gather your friends or family around, and watch them delight in this homemade blooming onion as it becomes the star of your gathering!

Make Ahead Options
These Crispy Air Fryer Blooming Onions are perfect for meal prep enthusiasts looking to save time! You can prepare the onion by cutting and coating it with seasoned flour up to 24 hours in advance. Simply store the coated onion in an airtight container in the refrigerator to maintain its texture and flavor.

This strategy allows you to enjoy a stress-free cooking experience while still impressing your guests with a deliciously crispy appetizer!

It’s all about allowing that hot air to circulate so each petal gets nice and crispy!
Are there any dietary considerations I should be aware of?
