Step‑by‑Step Instructions for Crispy Air Fryer Blooming Onion
Step 1: Prepare the Onion
Begin by cutting off about 1/2 inch from the top of the sweet onion, ensuring you leave the root intact to hold the petals together. Using a sharp knife, make diagonal cuts around the onion, about 1/4 inch apart, that go down to the root. Once you’ve finished, gently separate the petals to create that blooming effect, revealing the fresh layers inside.
Step 2: Coat the Onion
In a shallow bowl, mix all-purpose flour with any desired seasonings, like cayenne pepper for a kick. Roll your prepared onion in the seasoned flour, ensuring it penetrates between all the petals. Then, dip the onion into an egg wash, allowing any excess to drip off, before rolling it again in the flour mixture for a generous coating that will crisp beautifully during frying.
Step 3: Preheat Air Fryer
While you’re coating the onion, preheat your air fryer to 375°F (190°C). This step is crucial for achieving a perfect golden crunch. Ensure that the air fryer basket is clean and ready before placing the onion inside. Preheating will help the air fryer heat evenly, leading to that deliciously crispy result that makes the crispy air fryer blooming onion irresistible.
Step 4: Air Fry
Once preheated, gently place the coated onion into the air fryer basket. Spray the onion generously with oil spray to ensure it crisps up nicely. Cook the onion for approximately 12-15 minutes, checking for a rich golden-brown color. The crispiness will be inviting, and you’ll want to keep an eye on it so that it doesn’t overcook—look for that beautiful bloom to be fully opened!
Step 5: Check for Crispness
About halfway through the cooking time, carefully check on your blooming onion. Use tongs to gently separate any petals that might be sticking together, allowing hot air to circulate and crisp every layer. This will enhance the texture and ensure that each petal is deliciously crunchy. Continue cooking until the onion achieves that gorgeous, crispy exterior.
Step 6: Serve and Enjoy
Once cooked and crispy, carefully remove the blooming onion from the air fryer and let it cool slightly. Serve hot with creamy ranch or spicy mayo for dipping, allowing everyone to enjoy this delightful, restaurant-style appetizer. The combination of warmth, crunch, and flavor will make your crispy air fryer blooming onion a standout treat at any gathering!
