What it is
Everyone brings a dish and the meal is whatever arrives. There is a host, in the sense that someone provides the room, but there is no chef and no caterer and no one person carrying the evening.
The distribution of labor is the entire innovation, and it is the reason potlucks persist in churches, unions, immigrant communities, and departments long after formal entertaining has died out of the same populations.
Why it works
Hosting is the bottleneck on nearly all private gathering. A dinner party costs one household a day of shopping, cooking, and cleaning, plus the anxiety of performing competence, and that cost is why most people host once a year and then stop. A potluck divides that cost by twelve, and it does something better than divide it: it removes the performance. Nobody is being judged on the food, because the food is a committee.
That changes who can host. A small apartment and no cooking skill still qualifies, which widens the pool of possible hosts from the two people on your street with a dining room to essentially everyone. Infrastructure that only one household can operate is fragile; infrastructure anyone can operate rotates and survives.
It also builds in reciprocity mechanically. Everyone contributes something, which means nobody is a guest and nobody is in debt, and the absence of debt is a large part of why people come back. Compare that to being cooked for, which is lovely and creates a quiet obligation that many people avoid by declining.
And the food itself does social work. A dish is a small piece of self-disclosure, a grandmother's recipe or a regional thing or the one dessert you can make, and it hands everyone a conversation topic before anyone has to invent one.
Where it breaks down
Recurrence is the weak point, and it is a coordination problem rather than a design flaw. Most potlucks are occasional, tied to a holiday or a departure, and occasional gatherings never compound. The ones that turn into real infrastructure are the ones on a fixed schedule, first Sunday of the month, every month, whether or not anyone is in the mood.
There is also a labor asymmetry the format hides. Someone still cleans, someone still hosts, and in practice that someone is often the same person and often a woman. A potluck that rotates houses solves this; one that always lands at the same address is a dinner party with extra steps.
Make it count
Fix the date before you fix the guest list. "First Sunday, every month, my place, bring something" is a durable institution. "We should do a potluck sometime" is not.
Rotate the house. It spreads the cleaning, it lets everyone see how other people live, and it means the thing survives one family's rough month.
Keep the rules almost nonexistent. No sign-up spreadsheet, no assigned categories, and a store-bought contribution is fine. Every requirement you add is a reason for somebody to skip it.
