Blooming Onion with Zesty Dipping Sauce

This Blooming Onion recipe brings the restaurant classic right into your home kitchen with crisp, golden layers and a bold, creamy dipping sauce that packs a flavorful punch. Whether you’re hosting a party, preparing game-day snacks, or simply craving something indulgent, this appetizer checks every box for a satisfying, crowd-pleasing dish.

The preparation might look intricate, but with a few careful cuts and a good dip in seasoned flour and buttermilk, you can achieve that iconic blooming effect. Using a large Vidalia onion enhances the sweetness and texture, making each crispy bite more enjoyable.

What truly elevates this dish is the zesty dipping sauce—creamy with a kick of horseradish, balanced by the mellow tang of sour cream and a smoky hit from paprika. The contrast between the hot, crunchy onion and the cool, flavorful sauce creates an irresistible combination.

This recipe is perfect for four people but can easily be scaled up for more guests. Serve it fresh out of the fryer for that satisfying crunch and maximum flavor.
