A steamed cheeseburger, also referred to as a steamer or cheeseburg, is a hamburger topped with cheese that is cooked via steaming and originally only served by restaurants in central Connecticut in the United States.
The Connecticut steamed cheeseburger is reportedly the descendant of steamed beef-and-cheese sandwiches that were sold by horse-drawn carts to construction workers in the Hartford area of central Connecticut in the 1920s.
