Holiday potluck sign up sheet that balances the table

A potluck fails in a predictable pattern. Four people bring brownies, two bring chips, one brings a beautiful casserole that needs the oven at 400F while the ham is resting, and the ice arrives at the same time as the first guest. A sheet with named slots and amounts fixes all of it before anyone goes shopping.

Put the slots on a Bringalong event and share the link. Each dish is an item a guest claims, and the claimed ones show as taken, so the sixth person to open the invite sees that dessert is covered and picks up the bread instead. Replies, dietary flags and claims sit together on your manage link.

The split that stops seven desserts

Work in categories with a fixed number of slots in each, rather than a free-for-all list. For a holiday meal, the ratio that fills a table is one main dish per eight to ten guests, two starchy or vegetable sides per main, one salad per fifteen, bread for the whole room, and one dessert per ten guests. Cap the dessert slots and leave them capped. Three desserts for thirty people is plenty, because somebody will bring cookies anyway.

Write each slot as a dish plus a number: "hot vegetable side for 12" rather than "a vegetable." Guests cook to a quantity instead of guessing, and you stop getting a bowl of green beans meant for four people on a table of twenty. Keep one slot open for a vegetarian main and one for something that avoids the common allergens, since your dietary notes will tell you who needs them.

A sign-up sheet for 10 guests

Ten people usually means six or seven households, so roughly one dish each with the host taking the main. This is the size where you can run the whole thing off a single list and still have oven space left over.

Give the heaviest slot to the person who offered first, and keep the two easiest slots for whoever claims late. One guest will sign up on the morning of the party.

• Main: ham, turkey breast or a roast, sized for 10. Usually the host.
• Second main or vegetarian main: baked pasta, pot pie or a bean stew for 6.
• Potato or starch side for 10: about 5 pounds of potatoes.
• Hot vegetable side for 10: green beans, roasted carrots, sprouts.
• Green salad for 10: a pound of leaves, dressing in a separate jar.
• Bread and butter: 15 rolls, warmed on arrival.
• Dessert for 12 servings. One slot, not three.
• Drinks and ice: two bottles of wine, a case of soda, 10 pounds of ice.

Scaling to 20 and 30 guests

For 20, double the ten-person sheet but hold desserts at two and salads at two, which gives you about 14 slots. Add a second drinks slot and a slot for disposables. Two mains is the minimum and three is better, because a single ham for twenty disappears in the first ten minutes of a buffet line.

For 30, the limit is your oven and your table, not your guest list. Only two dishes fit in a standard oven at once, so ask on the sheet whether a dish needs oven time, fridge space or a power outlet, and nudge half the slots toward food that arrives cold or in a slow cooker. Thirty people also need a second serving station: a folding table with the sides on it, away from where the meat is being carved.

• Two large mains, each sized for 15, plus one vegetarian main for 8.
• Three starch sides for 10 each: potatoes, stuffing, rice or mac and cheese.
• Three hot vegetable sides for 10 each.
• Two salads for 15 each, dressings on the side.
• Bread: 45 rolls across two slots, with 2 pounds of butter.
• Three dessert slots for 12 servings each, and no more.
• Drinks team of two: wine and beer, plus soda, juice and mixers.
• Supplies team of two: 30 pounds of ice, 60 cups, plates, napkins, a folding table.

How much food per person

These are buffet amounts for adults, assuming three or four dishes end up on one plate. Dessert runs higher than people expect, because guests take two small pieces rather than one slice.

Count children aged five to twelve as half an adult for sides and a full adult for dessert. Then add a quarter to whichever dish is the only one of its kind: the sole vegetarian main gets eaten by meat eaters too. If you want leftovers for the host, add 20 percent to the mains and nothing else.

Drinks run at two in the first hour and one an hour after that, so a three-hour holiday potluck for 20 guests needs around 80 servings across wine, beer and soft drinks. Ice is the thing hosts underbuy: a pound per guest if you are chilling bottles in a tub, and a pound and a half if anyone is making cocktails.

• Main protein: 6 ounces cooked per adult, or half a pound raw bone-in.
• Starch side: 5 ounces. Hot vegetable: 4 ounces. Salad: 1.5 ounces of leaves.
• Bread: 1.5 rolls per person, plus 1 pound of butter per 15 people.
• Dessert: 1.5 servings per adult, and the same for children.
• Drinks: 2 servings in hour one, 1 per hour after.
• Ice: 1 pound per guest, 1.5 if there are cocktails.
• Disposables: 2 cups, 1.5 plates, 1.5 forks and 3 napkins per guest.
• Add 25 percent to any dish that is the only one of its type.

Who brings the ice, the cups and the rest

Put the non-cooking jobs on the same sheet as the food, with the same level of detail. These slots are where you send the guest who does not cook, the one arriving from the airport, and the one who signs up two days before. A guest asked for two bags of ice is usually relieved.

As host you keep the things that cannot travel: oven and fridge space, serving spoons for dishes that arrive without them, foil and plastic wrap, trash and recycling bags, a carving knife, and two power outlets free for slow cookers. Ask guests to bring their dish ready to serve, with their own serving utensil and a container for taking leftovers home.

• Ice: two bags for 20 guests, three for 30, delivered before the first guest.
• Cups, plates, forks and napkins, counted from the list above.
• Soft drinks, juice and mixers, plus a jug for water.
• Bread, butter and a bag of lemons or limes.
• A cooler, a folding table or a stack of chairs.
• Ground coffee, cream and a box of tea for the last hour.
• A set of serving spoons and a roll of foil, for the dishes that forget them.

Running the sheet without chasing people

Open the claim list the day you send the invite, and ask for two things with each claim: the name of the dish, and whether it needs the oven, the fridge or an outlet. That second answer is what saves you at 6pm, when three casseroles arrive cold and want different temperatures. Stagger arrival times by 15 minutes for anyone who needs reheating.

Close the sheet four days out, then look at the gaps. Fill them yourself or send a direct message to the two or three guests who have not claimed anything, naming the slot you want: "Could you take the green salad for 15?" A named ask gets a yes far more often than a group message about the sheet. Guests who sign up after the cut-off get ice, cups or drinks, which need no cooking and no oven.

• Ask for the dish name with the claim, so the table is readable in advance.
• Ask whether it needs oven, fridge or an outlet.
• Cap the oven dishes at two and point the rest at slow cookers or cold food.
• Close claims four days out and message the guests who have not claimed.
• Reassign late sign-ups to ice, drinks or disposables.
• Ask for allergens on a card next to the dish.
