These crispy Onion Rings are delicious as an appetizer or in Burgers. They’re made restaurant-style, which means they’re crispy on the outside, tender on the inside, and seasoned to perfection. The secret to these is double-dipping. This creates a beautifully crispy crust. Once cooked, the onions inside are tender and sweet. That strong raw onion flavor fades to the background, replaced with the crispy outer coating and seasoning.
