  • 4 egg whites whisked until frothy
  • 1 large sweet onion halved and slice vertically {discard the thick center pieces}
  • 2 cups panko breadcrumbs
  • 1 cup unbleached all-purpose flour
  • 4 teaspoons all-purpose season salt divided
  • 1 teaspoon garlic powder divided
  • 1/2 teaspoon black pepper divided
  • 1/4 teaspoon cayenne pepper divided


  • 2/3 cup mayonnaise
  • 1/3 cup ketchup



  • Preheat your oven to 400° and line a rimmed sheet pan with parchment or silicon baking mat.
  • Place the onion petals, flour, bread crumbs and egg whites in separate bowls. Divide the spices among the flour and the breadcrumbs, so that's 2 teaspoons of the all purpose seasoning, 1/2 teaspoon of garlic powder, 1/4 teaspoon black pepper and 1/8 teaspoon of cayenne in both bowls and mix to combine.
  • Dip the onion petals in the flour and shake off the excess. Dip the petals into the egg whites and let the extra whites drip off.
  • Then place the flour and egg coated onions into the seasoned breadcrumbs and toss to coat.
  • Place the breaded onions onto the prepared sheet pan and repeat with the remaining onions.
  • Bake in your preheated oven for 18-20 minutes, rotating the pan halfway through baking.
  • Serve immediately with the fry sauce and start dipping.


  • Combine 2/3 cup mayo and 1/3 cup ketchup, mix until smooth, cover and store in the fridge until you're ready to serve.
