The strange casserole was invented in 1955 by Dorcas Reilly at the Campbell Soup Company.
Reilly grew up in Camden, N.J. and studied home economics at Drexel University. She began working in a small team at Campbell in 1949, according to Campbell.
In the mid-1950s, Reilly set out to make a quick and easy dish that could be made from ingredients that most Americans have in their pantry. Reilly determined most households have leftover cans of Campbell's cream of mushroom soup and a stash of green beans. With these two staples, the Green Bean Casserole was born.
The recipe requires only five or six ingredients, it's surprisingly easy to make, and can be adjusted to fit a range of tastes.
In 2002, Reilly donated the original copy of her green bean casserole recipe to the National Inventor's Hall of Fame. The yellowed 8 X 11 recipe card can now be found among Enrico Fermi's invention of the first controlled nuclear reactor and Thomas Alva Edison's light bulb and phonograph.
