National Hamburger Day is observed each year on May 28 2017.
This day celebrates a summer-time grilling favorite and National Hamburger Day is part of National Hamburger Month.

Try Steve’s Smashburger! (Steve’s is the home of the original Smashburger). Our Smashburger is loaded with dijon mayo, lettuce, grilled red onions, american cheese, tomatoes, dill pickle chips on a corn dusted kaiser roll! Or order a cheese burger! Any one of these combinations would create a modern American version a hamburger.
It is most likely that the hamburger sandwich first appeared in the 19th or early 20th centuries, but there is much controversy over its origin. Over the years, the hamburger has become a culinary icon in the United States.
