🧄 The Viral Onion Hack You’ll Wish You Knew Sooner
If you’ve seen the TikTok-famous onion boil party, you already know it’s a vibe: buttery onions bobbing in a Cajun bath, usually cooked over an open flame. But what if you don’t have the time—or a gallon of seasoning?
This air-fried whole onion recipe gives you all the flavor with none of the mess. It’s sweet, savory, melty in the middle and crispy on the edges—and it only takes 10 minutes to prep and 15 minutes in the air fryer/

It’s even better than the original.—
