Potluck dinners are a beloved tradition in which guests bring a dish to share with the host and other guests. However, there are several alternatives to the term "potluck" that can be used to inject a bit of variety and let your guests know what to expect. "Community dinner" or "family-style feast" suggests a more communal and inclusive approach, while "shared meal" or "covered dish party" emphasizes the sharing of food. "Bring and share dinner", "buffet-style meal", or "feast of friends" are also useful terms to describe this social event where everyone contributes and enjoys a variety of home-cooked dishes.
