was served in 20 million Thanksgiving dinners in the US each year. Campbell's in 2020 reported their online version of the recipe is viewed 4 million times each Thanksgiving Day. According to Campbell's as of 2018, the recipe is the most popular ever developed in their kitchens. Folklorist Lucy Long in 2007 noted that its inclusion on Thanksgiving dinner tables crosses ethnic, socioeconomic, and religious differences. She also notes it is included in most popular American cookbooks, mentioned in the media regularly, and referred to a "classic", "traditional", and "a Thanksgiving standard". She wrote that the popularity of the dish was related to its categorization as a casserole, which in the US is associated with "communal eating, sharing, and generosity" and that the green bean casserole in particular represents the familiar and also the festive. Ingredients The recipe, which hasn't changed, calls for green beans, mushroom soup, milk, soy sauce, ground black pepper, and french fried onions. The beans, soup, milk, and seasonings are mixed together with a portion of the onions and baked, then topped with more onions and baked for another few minutes. Multiple similar recipes have been developed that "update" or "upgrade" the original recipe to use fresh beans, homemade cream sauce, and fresh mushrooms as the convenience-food based recipes of the 1950s and 1960s have become less fashionable, but according to culinary historian Shapiro, the green bean casserole remains popular for Thanksgiving for reasons of nostalgia. Other recipes have been developed, by Campbell's and others, that incorporate a variety of ingredients in addition to or in replacement of those in the original. Creator In November of 2002, Reilly, representing Campbell's, donated the original recipe card to the National Inventors Hall of Fame in Akron, Ohio. The donation was followed by a meal featuring the dish. Reilly died 15 October 2018, at the age of 92 in her hometown of Camden, New Jersey.
