Running a potluck when someone has a food allergy

A potluck is the hardest format to make safe because you control neither the ingredients nor the kitchens — so either assign dishes and require ingredient lists, or tell the affected guest honestly that the food cannot be cleared and plan a safe dish they can rely on.

Decide which kind of potluck this is

  • Option one: a controlled potluck, where you assign dishes, set a banned-ingredient list, and require every contributor to send an ingredient list in advance.
  • Option two: an open potluck, where you accept that contributed food cannot be cleared and you personally prepare a safe meal for the affected guest.
  • Choose one and say which it is. The dangerous version is the open potluck presented as if it were controlled.
  • Tell the affected guest which model you are running, before the event, so they can decide for themselves.

If you run a controlled potluck

  • Give contributors a short banned list with the Swedish and English names of each allergen, not a category like 'nuts'.
  • Require an ingredient list per dish, including for anything bought in, and ask people to bring the packaging.
  • Say explicitly that 'may contain' products are excluded, because most contributors will not think of them.
  • Remind people about the kitchen as well as the recipe: a dish made on a floured board or in a shared pan is not cleared just because the ingredients are.

Label and serve

  • Every dish gets a card listing what it contains. Handwritten is fine; unlabelled is not.
  • Every dish gets its own serving spoon, and the spoons stay with the dish. This is the single most common failure at a shared table.
  • Serve the affected guest first, before the table has been through once.
  • Put the safe dishes at the start of the table and the unlabelled or uncleared ones at the end, so nothing drips backwards along the line.

Be honest about the limits

  • Tell the affected guest what you could verify and what you could not. Specific honesty is more useful than general reassurance.
  • Offer a dish you made yourself, from ingredients you can show them, as a reliable option.
  • Support their decision if they choose to bring their own food or to eat beforehand — for many people with severe allergies this is the normal and sensible approach to a potluck.
  • Keep all packaging until the event ends so any question can be checked against a label.

Common questions

Can a potluck ever be safe for a serious allergy?

It can be made much safer with assigned dishes, ingredient lists and disciplined serving, but it cannot be made equivalent to a meal you cooked yourself, because you cannot inspect other people's kitchens. Say that plainly rather than implying otherwise.

What is the most common mistake at a shared table?

Serving spoons moving between dishes. It happens within minutes, it is invisible afterwards, and it undoes every other precaution. One spoon per dish, said out loud once, prevents most of it.

Should I ban an allergen from the whole potluck?

For a severe allergy, yes — it is far easier for contributors to follow one clear exclusion than to label accurately. For a milder one, labelling and separate spoons are usually proportionate.

Is it rude for a guest to bring their own meal?

No, and a good host makes it easy. For many people with severe allergies it is the standard approach to any event they do not control — treating it as normal is more welcoming than insisting they eat the shared food.
