In celebration of Super Bowl weekend, Burger King will give away its famous onion rings for free to any customers who visit on the first weekend of February 2012. Burger King says it will give away one value size onion rings order per person per visit on Feb. 4 and 5. Lynn Swann, an NFL Hall of Famer and a four-time Super Bowl Champion with the Pittsburgh Steelers, was picked by Burger King to help kick off a big weekend of football and fried rings.

I am happy to work with Burger King to make sure that everyone knows how to get their free onion rings during this weekend of championship football, said Swann, the former wide receiver. Since I have my rings, I wanted to make sure you could get yours. And you don't have to stop at four!!

One value sized order of Burger King onion rings contains 150 calories, 8 grams of fat, 1.5 grams of saturated fat and 400 milligrams of sodium. One order also contains 19 grams of carbs and two grams of sugar.

Burger King says the free onion rings event will be held at participating locations, so check Burger King's restaurant locator to see if the stores nearby you will be giving away the new thick-cut fries. A Burger King spokesperson said the company will sell the rings on Feb. 4 and 5 after breakfast hours, but other locations will likely give away the onion rings during all hours. Some Burger King stores are open 24/7, while others typically open at 7 a.m. and close at 12 a.m. midnight.

On Dec. 16, Burger King revamped its French fries to make them thicker and fluffier, and similarly decided to introduce the new product to the public by giving value size portions of the new menu item away for free. Burger King changed the fries to make them healthier by removing all animal products from the ingredients list, reducing the amount of sodium by 20 percent, and cooking the fries in trans fat-free vegetable oil.

In October 2010, Burger King was purchased by 3G Capital, a private investment firm. Since then, Burger King has introduced a number of new items to its menu, including BK Toppers, Stackers and Mini lines, a Stuffed Steakhouse burger, revamped chicken tenders, Quaker oatmeal, soft serve ice cream and more. Today, Burger King is the No. 2 burger chain after McDonald's, with 12,400 outlets in 73 countries.
