Tips for the Best Blooming Onion Bites

Use Sweet Onions

Sweet onions provide the best flavour and become perfectly tender.

Don’t Overcrowd the Oil

Cooking too many at once lowers the temperature and creates soggy coating.

Double Coat for Extra Crunch

For an extra crispy crust, repeat the egg and breadcrumb steps.

Serve Immediately

These bites are best while warm and crunchy.

Cool oil causes greasy, soft bites.
