What’s the best way to generate hype for a new menu item? Offering it for free, of course.

Burger King will offer its new lower-calorie, lower-fat French fries, Satisfries, for free this weekend to all customers with no purchase necessary. On Saturday, Oct. 12 and Sunday, Oct. 13 during regular business hours, the burger giant will hand out free Satisfries to all customers – with a one-per-customer limit – without coupons or even a purchase.

The fast food giant rolled out its new lower-calorie, lower-fat crinkle-cut fries in late September, at only 30 cents more than an order of regular French fries. However, according to a Burger King rep, millions of customers have yet to try the latest healthier alternative menu item, which took months of research to perfect.

“Many of our guests have already fallen in love with new Satisfries and if you haven't tasted them, you're missing out." Burger King president of North America Alex Macedo said. "We invite guests to bring family and friends."

The freebie will be the value-sized Satisfries, which normally cost $1.29, and Burger King expects it will hand out an upwards of 10 million orders, Macedo said. The offer is valid at participating restaurants, with no purchase necessary, but not in Alaska. Check the Burger King locations website to find a chain near you.

The last time Burger King offered free French fries to its customers was in December 2011 when it introduced its thick-cut style fries.

The new Satisfries contain 190 calories and 8 grams of fat, which Burger King said is 30 percent fewer calories and 40 percent less fat than a serving of rival McDonald’s fries. The new fries have 270 calories, compared with 340 for a small order of regular fries. Satisfries cost $1.89  for a small compared to $1.59 for regular fries and have no price difference when included in Kids Meals.

Satisfries have fewer calories and less fat thanks to a new batter recipe and a crinkle-cut that doesn’t absorb as much oil in the frying process, the company said. They have the same ingredients – potatoes, oil and batter – as regular fries and are made in the same fryers and cooked in the same oil for the exact amount of time as regular fries. The Associated Press reported the new recipe “adjusts the proportions of different ingredients for the batter to block out more oil.” Burger King did not elaborate further on the process in reports.

Earlier this month, Burger King released a fake ad campaign, which fooled many fans, after it changed its name to “Fries King” to promote the news Satisfries. The fast food chain said it would temporarily be called “Fries King” and changed its logo on its website with an accompanying slogan, “Formerly Burger King.”

Eventually, the ruse was called off and Burger King went back to its original name.
