There's no wrong way to eat an onion ring and they’re so good that multiple countries claim to be the original origin. With the past week celebrating the National Onion Ring Day, here’s how to earn free onion rings from Burger King.

Burger King is offering a free order of onion rings with every purchase of at least $1, but the purchase must be made through the app or website. Additionally, you also have to be a part of the Burger King's Royal Perks program to participate. However, Burger King's onion rings may not be your first choice, and they were once called "supremely unpleasant" and "an abomination."

But today, they're free! An onion ring is delicious even at its worst, and on this day, there's an unspoken "no onion ring left behind" policy. Plus, when you purchase something online at Burger King and bite into the rings, you're automatically part of the celebration.
