Cut off the root end of each sweet onion. Slice the onion in half vertically and make gentle vertical cuts around the sides, ensuring to stop just before reaching the base.

Fill a bowl with ice water and gently place cut onion petals inside. Soak for about 10 minutes.

In a mixing bowl, combine the flour with the seasoning blend. In another bowl, beat the eggs until frothy.

Dip each onion petal into the egg mixture, then transfer to the flour mixture, pressing lightly to adhere the coating.

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. Arrange the coated onion petals on the baking sheet, leaving space between them. Bake for 20-25 minutes until golden brown and crispy.

Remove from the oven and let cool for a few minutes. Serve hot with your favorite dipping sauces.
