Green bean casserole, is a food a product invented in 1955 by what company?

Green bean casserole was invented in 1955 by the Campbell Soup Company.

The recipe was developed by Dorcas Reilly, who worked in Campbell’s test kitchen and home economics department in Camden, New Jersey. It was designed for an Associated Press feature as a quick dish using ingredients many American households already had available. The original recipe combined green beans, Campbell’s cream of mushroom soup, milk, soy sauce, black pepper, and fried onions.

When first created, the dish was called “Green Bean Bake.” Campbell’s later printed the recipe on soup-can labels, helping it spread nationwide. Its creamy mushroom sauce and crisp fried-onion topping made it especially convenient for busy home cooks.

Although it was initially marketed as an everyday side dish, green bean casserole became strongly associated with Thanksgiving during the 1960s. The company estimates that millions of American Thanksgiving meals include a version of it. The company is often credited with the invention, while Reilly is the specific recipe creator behind the dish.
