Can I make this blooming onion ahead of time?
Yes. Slice and season the onions up to 4 hours ahead; store in an airtight container in the fridge. Air fry just before serving for maximum crispness.
Why is my air fryer blooming onion soggy?
Overcrowding the basket traps steam. Cook in a single layer and shake the basket halfway through. Pat onions dry before cooking if they're wet.
What temperature and time do I use for the air fryer?
Most air fryers work best at 380–400°F for 12–15 minutes, shaking halfway. Check your model's manual and adjust timing if needed—onions should be golden brown and crispy at the edges.
Can I use a different oil instead of avocado oil?
Yes. Vegetable oil, canola oil, or olive oil all work. Choose an oil with a high smoke point for best results in the air fryer.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 2 days. Reheat in the air fryer at 350°F for 3–4 minutes to restore crispness.
