Cook techniques
Prepping the Onion
Trim the top of the onion and peel the outer skin carefully to keep the root intact. This aids in creating a visually appealing bloom.
Cutting the Onion
Make downward cuts to divide the onion into sections. Ensure that the cuts are deep enough but not through the root, allowing the onion to hold its shape.
Separating Layers
Gently separate the onion layers after making the cuts to achieve a flower-like appearance. This helps in the even coating of the egg whites and breadcrumbs.
Coating Process
Whisk the egg whites until frothy to create a sticky base for the breadcrumbs. Use a brush to apply the egg whites on each onion petal evenly.
Breadcrumb Mixture Application
Sprinkle the breadcrumb mixture generously on each petal after coating with egg whites to ensure that every section is flavorful.
Baking Technique
Initially cover the onion with foil to retain moisture, then uncover it to achieve a crispy golden-brown finish on the edges.
FAQ
Can I use regular breadcrumbs instead of Panko?
Yes, though Panko provides a lighter, crunchier texture, regular breadcrumbs can be used but may yield a different consistency.

Many dipping sauces work well, such as ranch, garlic aioli, or a spicy dipping sauce to complement the Cajun seasoning.
Can I prepare the onion in advance?
While best served fresh, you can prepare the onion up to the baking stage and refrigerate it until you are ready to bake.
How do I store leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat in the oven for best results.
