The office or lab potluck people actually look forward to

The workplace potluck has a mixed reputation. Done badly, it is nine bags of chips and one orphaned casserole. Done well, it is the one lunch of the year when the lab and the front desk and the people from the third floor all end up at the same table. The difference is mostly planning.

Make a sign-up sheet

Use a shared spreadsheet or a sheet on the kitchen wall. Set up simple categories and ask people to fill them in:

• Mains (two or three)
• Sides and salads
• Something vegetarian or vegan
• Desserts
• Drinks, plates, napkins, cutlery

Include a column for “what is it” and “contains”. Nobody should have to ask whether the stew has peanuts. If a category fills up, ask for another one rather than ending up with six desserts.

For people who do not cook, or who do not have time, let them bring ice, fruit, bread or paper goods. Everyone contributes something. Nobody has to prove they can cook.

Pick dishes that travel and reheat

Think about the real conditions: a car or a bus, a shared fridge, one microwave and a lunch hour. Dishes that work:

• Baked pasta, lasagna, rice bakes: reheat evenly and hold well
• Curries, stews and chili: better after a day, easy in a slow cooker
• Grain salads (couscous, quinoa, barley): good at room temperature
• Roasted vegetables with a dressing on the side
• Mini muffins, brownies, cookies, fruit platters: no cutting needed
• Dips with vegetables and crackers

Dishes that struggle: anything that must be fried to order, delicate salads that wilt, and very large cakes with no plates or knife.

Label everything

Ask each cook to put a small card by their dish with the name and main ingredients. Highlight the common allergens: peanuts, tree nuts, milk, eggs, wheat, soy, fish, shellfish and sesame. Mark vegetarian, vegan, halal or gluten-free only if you are sure. Guests who avoid certain foods for religious or health reasons will read the cards carefully, so be accurate.

If your workplace has a nut-free policy, include it on the sign-up sheet. This article is general advice, not medical advice. People with severe allergies should decide for themselves what is safe.

Keep it safe

Food-safety rules at the office are the same as at home:

• Keep cold food cold (fridge, ice) and hot food hot until serving.
• Do not leave perishable food out for more than about two hours.
• Reheat cooked dishes until steaming hot all the way through.
• Provide serving spoons for every dish, so people do not use their own forks.
• Wipe the table and wash hands before eating.

A small bottle of hand sanitizer on the table helps.

Build the little rituals

• A theme can help: soups in January, a “dish from your family” lunch, a breakfast potluck before a big meeting.
• A short toast or a thank-you from the team lead takes 30 seconds and makes people feel noticed.
• Recipe sharing: a folder or shared page of recipes lets the dish live on after the lunch.
• Mix the tables. A name-card seating plan feels formal, but a simple rule of “sit next to someone you do not usually eat with” works wonders.

After the meal

Offer containers so people can take leftovers home, and label the fridge items with the date. Clean up as a group. Twenty people with a cloth each can finish in ten minutes. Return dishes and slow cookers to their owners before they leave, with names on the bottom in masking tape.

What can go wrong

• Too much food or too little. Plan about one serving per category per person, then adjust after the first event.
• Blown fuse. If five people bring slow cookers, check your outlets.
• Awkward silence. Put someone in charge of warmly greeting newcomers.

A potluck is a cheap way to turn colleagues into neighbours. For more ideas for bringing people together over food, see our community section.
