Some fast food items are so iconic that they have shaped fast food as we know it. The Big Mac, the bargain bucket, and of course, the Frosty are probably ones that come to mind, but we have the official rundown of the 20 most iconic fast food items of all time. A study carried out by Yardbarker has determined the most famous fast food items of all time, so any foodies out there can use this list as a kind of bucket list to eat your way through.

Without further ado, here are the 20 most iconic fast food items of all time. The fact that this is a seasonal menu item only adds to the allure. This bright green peppermint shake is a St.

Patrick’s Day staple at McDonald’s, and although the shake has an insane 97 grams of sugar in it (that’s 27 sugar cubes), people go crazy every year over this elusive drink. The Shamrock Shake is a longstanding seasonal menu item at McDonald’s. It was first invented in 1967 and has become synonymous with the Irish holiday ever since.

Mashed potatoes, corn, gravy, cheese, and popcorn chicken. What’s not to love? Top this thing with gravy and you’re in comfort food heaven. The clue is in the name, this is a truly iconic item from KFC.

KFC Famous Bowls were launched in May 2006, and have become a staple of the menu ever since. Wendy’s specializes in creating menu items that would be weird if they were served anywhere other than at Wendy’s. Although ordinary, something about the humble baked potato at Wendy’s is so tasty and comforting.
