Onion rings with homemade ranch dressing

Chef Frank's Gluten-Free Onion Rings

Chef Frank Proto says making your own onion rings (and ranch dressing) is not as hard as you think it is.

In the latest episode of Epicurious' 4 Levels series, Chef Frank's pro version of onion rings minimizes grease and happens to be gluten-free.

"Whenever I think of onion rings, I think of beer batter," Chef Frank explains while demonstrating his approach to the snack — you can use gluten-free beer or substitute seltzer if desired. He uses white onions for thin, uniform layers and thick slices because more surface area means more batter will stick. Chef Frank seasons both sides of his onion slices and cooks in vegetable oil for depth of flavor, and makes his ranch dipping sauce with fresh ingredients saying "it's a lot better than what you get out of the packet."
