Ingredients

Scale
  • 1 large yellow onion
  • 1 cup all-purpose flour
  • 2 teaspoons paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon cayenne pepper
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 large eggs
  • 1/2 cup milk
  • 1 cup panko breadcrumbs
  • 1/2 cup grated Parmesan cheese
  • For the Spicy Aioli:
  • 1 cup mayonnaise
  • 2 cloves garlic, minced
  • 1 tablespoon sriracha (or more, to taste)
  • 1 teaspoon lemon juice
  • 1/2 teaspoon smoked paprika
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
  2. Prepare the onion: Cut off the top 1/2 inch of the onion. Place the onion root-side down. Make cuts from the top, about 1/2 inch apart, stopping just before you reach the root. This will create the ‘petals’. Gently spread the petals apart.
  3. In a shallow bowl, whisk together flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper.
  4. In another shallow bowl, whisk together eggs and milk.
  5. In a third shallow bowl, combine panko breadcrumbs and grated Parmesan cheese.
  6. Dip the onion into the flour mixture, ensuring all petals are coated. Shake off excess.
  7. Dip the floured onion into the egg mixture, letting excess drip off.
  8. Press the onion into the panko-Parmesan mixture, ensuring it is well coated. Gently press the mixture into the petals.
  9. Place the coated onion on the prepared baking sheet, root-side down.
  10. Bake for 35-45 minutes, or until the onion is tender and the petals are golden brown and crispy.
  11. While the onion bakes, prepare the aioli: In a small bowl, combine mayonnaise, minced garlic, sriracha, lemon juice, and smoked paprika. Stir until well combined. Season with salt and pepper to taste.
  12. Let the baked onion cool slightly before serving. Serve with the spicy aioli for dipping.

Notes

  • For an extra crispy onion, you can double-dip it: after the egg wash, dip it back into the flour mixture before the panko coating.
  • Adjust the amount of sriracha in the aioli to control the spice level.
  • If you don’t have panko, you can use regular breadcrumbs, but the texture will be slightly different.
