Instructions
Preparation Steps
Peel the onion and cut off the top (stem end), leaving the root intact. Turn the onion cut-side down and make 12–16 vertical cuts from top toward the root, stopping about 1/2 inch from the root so the petals stay connected.
Carefully turn the onion over and spread the petals apart to form a 'bloom.' Chill the cut onion in the refrigerator for 10–15 minutes to help it hold its shape.
In a shallow bowl, whisk the egg and milk together to make the wet batter.
In a separate bowl, combine the flour, cornstarch, paprika, garlic powder, onion powder, cayenne, salt, and black pepper. Mix well.
Dredge the chilled onion in the seasoned flour mixture, making sure to get the flour between the petals. Shake off excess flour.
Dip the floured onion into the egg-and-milk mixture, coating thoroughly, then press into the panko breadcrumbs so the crumbs adhere to all petals.
Place the breaded onion back in the refrigerator for 10 minutes to set the coating while heating the oil.
Heat the oil in a deep pot or fryer to 350°F (175°C). Carefully lower the onion into the hot oil, cut-side down, and fry for 3–5 minutes until the coating is golden brown. Flip and fry an additional 2–3 minutes if needed to cook through.
Remove the onion from the oil and drain on a wire rack or paper towels. Let rest for a minute, then serve immediately with your favorite dipping sauce.
Notes
For best results, use a very large sweet onion and serve hot. Leftovers can be reheated in a hot oven to restore crispness, but the onion is best enjoyed fresh.
