Ingredients

Scale
  • 2 medium-sized large onions (preferably sweet yellow or Vidalia)
  • 1 ½ cups buttermilk (360 ml)
  • 1 cup all-purpose flour (120 g)
  • 1 ½ cups panko breadcrumbs (150 g)
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • 1 teaspoon salt, or to taste
  • ½ teaspoon freshly ground black pepper
  • 2 large eggs, beaten
  • Olive oil or avocado oil spray
  • For the Smoky Chipotle Sauce:
  • ½ cup mayonnaise (120 g, full-fat)
  • 12 chipotle peppers in adobo sauce, finely chopped
  • 1 tablespoon freshly squeezed lime juice
  • 1 teaspoon honey
  • A pinch of salt

Instructions

  1. Peel the onions and slice into ½-inch (1.25 cm) thick rings. Gently separate the rings from each other, keeping them intact. Set aside.
  2. Pour buttermilk into a large bowl and add the onion rings. Let them soak for at least 30 minutes, or up to 2 hours in the fridge.
  3. Preheat your oven to 450°F (230°C). Place a wire rack on a baking sheet and lightly spray with oil.
  4. In one bowl, whisk the eggs. In another bowl, combine flour, panko breadcrumbs, smoked paprika, garlic powder, onion powder, salt, and pepper.
  5. Remove rings from the buttermilk one at a time, letting excess drip off. Dip into the flour mixture, then into the beaten eggs, and again into the flour mixture for a double coating. Press the coating gently to help it adhere.
  6. Place coated rings on the wire rack on the baking sheet in a single layer. Spray the tops lightly with oil.
  7. Bake for 15 minutes, then flip the onion rings carefully using tongs, spray again with a light coat of oil, and bake an additional 10-15 minutes until golden and crispy. Watch closely after 20 minutes to avoid burning.
  8. While the rings bake, mix mayonnaise, chopped chipotle peppers, lime juice, honey, and a pinch of salt in a small bowl. Adjust heat by adding more peppers if desired. Chill until ready to serve.
  9. Serve the onion rings hot with the smoky chipotle sauce on the side for dipping.

Notes

Double coating with flour, egg, and flour is key for crispiness. Use panko breadcrumbs for extra crunch. Use a wire rack to ensure even baking and crispiness. Spray lightly with oil before baking. Watch baking time closely to avoid burning. Pat rings dry after soaking if coating doesn’t stick well. Do not overcrowd the pan.
