Ingredients
  

Main Ingredients
  • 1 large onion Use a firm onion for better petals.
  • 1 cup all-purpose flour
  • 1 teaspoon paprika For warmth.
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 cup buttermilk Adds tang and helps the coating stick.
  • 1 cup breadcrumbs Plain breadcrumbs keep it light.
  • as needed spray cooking spray To spray the onion for even browning.

Method
 

Preparation
  1. Heat your oven to 400°F (200°C). Line a baking sheet with foil and lightly oil it.
  2. Trim the top of the onion and peel the outer layer. Place onion root-side down and make vertical cuts about 1/2 inch apart, slicing down towards the root but stopping before cutting through. Gently open the petals.
  3. Whisk together flour, paprika, garlic powder, onion powder, salt, and black pepper in a shallow bowl.
  4. Dip the onion into buttermilk, letting it drip for a moment. Coat well in the flour mix, ensuring each petal has a dusting.
  5. Dunk the onion again in buttermilk, then press it into the breadcrumbs for a crunchy finish, ensuring crumbs reach between petals.
  6. Place the onion on the prepared sheet and spray the top and sides with cooking spray.
Baking
  1. Bake for 25-30 minutes until you see golden edges and hear a crisp sound when tapping a petal.
  2. Let it rest for 5 minutes before serving with your favorite dipping sauce.

Notes

Prep flour and breadcrumbs in two shallow dishes to speed up assembly. If petals stay closed, re-cut deeper near the root for heat access. For extra flavor, sprinkle smoked paprika or add grated Parmesan to breadcrumbs.
