'Countless hours and incredible ingenuity went in to accomplishing this enormous accomplishment. 'I'm very proud of everyone involved in setting this record,' Black Bear Casino Resort Executive Chef Gerald Bayerl said. More than 60 pounds of bacon, 50 pounds of lettuce, 50 pounds of sliced onions, 40 pounds of pickles and 40 pounds of American cheese topped off the burger. The behemoth burger was 10-feet in diameter and weighed 2,014 pounds, breaking the previous record of 881 pounds and 13 ounces in the biggest burger one-off event category. Black Bear Casino Resort smashed the Guinness World Record for largest hamburger Sunday with a bacon cheeseburger weighing more than a ton.
