1 Cut ends off of the onion and then slice into 1/2 inch wide sections. Remove each ring from the sections and place in cold water for 5 minutes or so.
2 Preheat oven to 450ºF.
3 Take each onion ring and shake dry. Place in bowl with flour (shake off excess), then dip in egg (shake off excess), and cover with bread crumbs (yep… shake off the extra crumbs). Place on the baking sheet.
4 Lightly spray with cooking spray and bake for 7-8 minutes. Flip each onion ring over and bake for another 5-6 minutes.
