Ingredients
  

  • 2 large sweet onions
  • 1 cup all-purpose flour
  • 1/2 cup cornstarch
  • 1 tsp salt
  • 1 tsp black pepper
  • 1 tsp paprika
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp cayenne optional for heat
  • 2 eggs
  • 1 cup buttermilk or milk + 1 tsp vinegar
  • Oil for frying
  • Dipping Sauce optional
  • 1/2 cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp horseradish sauce
  • 1/2 tsp paprika
  • 1/4 tsp garlic powder
  • 1/4 tsp salt
  • Pinch of cayenne

Instructions
 

  • Peel onions and slice into large petals by cutting into wedges and separating layers.
  • In a bowl, whisk flour, cornstarch, salt, pepper, paprika, garlic powder, onion powder, and cayenne.
  • In another bowl, whisk eggs with buttermilk.
  • Dip onion petals into the flour mixture, then into the egg mixture, then back into the flour mixture for a double coating.
  • Heat oil to 350°F (175°C). Fry petals in batches for 2–3 minutes until crisp and golden.
  • Drain on paper towels.
  • Mix all dipping-sauce ingredients if using.
  • Serve warm with sauce.

Notes

Sweet onions (like Vidalia) give the best flavor.
For extra crispy petals, let them rest 5 minutes after breading before frying.
Air fryer option: spray well with oil and air fry at 400°F (200°C) for 8–10 minutes, shaking halfway.
