A Thanksgiving potluck sign-up sheet guests can fill in themselves

The sheet is where a potluck goes wrong. Twenty guests sign up for whatever sounds nice, you get four desserts and two vegetables, and the one person bringing potatoes brings a bowl that feeds five. The sheet has to ask for amounts, cap the categories, and show what is already taken.

You can run it on paper taped to a fridge, in a shared doc, or as a Bringalong invite where each item is claimable and the claimed ones show as gone. Whichever you pick, build the list yourself before you share it. Open sign-up sheets with blank rows collect pie.

What goes on a sign-up sheet for 20 people

One dish per two guests, plus the main, plus drinks and supplies. For twenty people that is the turkey and gravy from the host and about ten claimable dishes. Anything beyond that and food goes home untouched, because people take a spoonful of eight things rather than a plate of three.

Here is a list you can copy and adjust. Write the servings next to each line, because servings are what guests get wrong.

• Turkey, 20 pounds raw, or two 12 pound birds, plus 7 cups of gravy. Host, because gravy needs the pan drippings.
• Mashed potatoes for 20, which is 10 pounds of potatoes.
• Stuffing, two 9 by 13 dishes, about 24 cups. Two claims.
• Sweet potato dish for 12 and a green vegetable for 12. Two separate claims.
• Cranberry sauce, 5 cups, a green salad for 20, and 40 rolls with butter.
• Cheese and crackers for 20, to put out at arrival.
• Three 9-inch pies, which cut into 24 slices, and one non-pie dessert.
• Drinks: 8 bottles of wine, 4 large bottles of soda, 20 pounds of ice.

Servings per dish, so nothing arrives in a cereal bowl

Ask for a number, not a dish. Green beans for ten gets you a tray. Green beans gets you whatever was in the fridge. If a guest is bringing one of eight sides, half a cup per person is the right portion, which works out to a 9 by 13 dish feeding about twelve as one side among several.

These are the per-head amounts that hold up at a table of twenty. They assume people eat a bit of most things and go back for seconds of two.

• Turkey: 1 pound raw bone-in per person, 1.5 pounds if you want leftovers.
• Potatoes: half a pound per person before peeling.
• Stuffing: three quarters of a cup per person.
• Gravy: a third of a cup per person.
• Vegetable side: half a cup per person per dish.
• Cranberry sauce: a quarter cup per person.
• Rolls: two per person.
• Dessert: one and a quarter slices per person across all desserts.

Cap the categories before you share the list

A sheet with ten blank lines turns into six desserts. Write the category and the number of slots, then let guests fill only those slots: three dessert slots, two starch slots, two vegetable slots, one salad, one bread, one appetizer. When the slots are gone, they are gone, and the next guest brings ice or wine.

Leave two or three slots deliberately easy. Somebody on the list has no kitchen, is driving three hours, or cooks badly and knows it. Ice, rolls, drinks, a cheese board and disposable plates are real contributions and they stop the awkward conversation where a guest says they will bring nothing.

Oven slots, outlets and the reheating order

One oven holds two 9 by 13 dishes side by side, or three across two racks if you rotate them. A casserole from a cold fridge needs 30 to 35 minutes at 350 F. So mark the sheet with how many dishes need the oven, and cap it at four. Everything else should arrive hot in a towel-wrapped dish, in a slow cooker, or be fine at room temperature.

Outlets matter more than people expect. A slow cooker draws 200 to 300 watts and you can run four on a kitchen circuit. An electric roaster or griddle pulls 1200 to 1500 watts, and a 15-amp circuit tops out near 1800, so two of those on the same circuit trips the breaker in the middle of carving. Ask on the sheet which guests are bringing something that plugs in.

A worked reheat order for a 5 pm dinner with one oven: turkey out at 3:15 and tented, oven up to 375 F, stuffing and sweet potatoes in at 3:20 for 35 minutes, those out and covered with foil at 3:55, second stuffing tray and the green vegetable in until 4:20, rolls in for eight minutes, carve at 4:30, serve at 5.

Labels, allergies and the supplies nobody claims

Put an index card in front of each dish with the dish name and anything in it that people ask about: dairy, gluten, nuts, shellfish. Ask for that on the sheet when a guest claims an item, so the labels are written before the doorbell goes. It takes one line of typing from each guest and spares you standing over a table listing ingredients from memory.

Then there is the unglamorous half of the sheet. Twenty people need about 30 plates, 40 forks, 40 cups, eight serving spoons, four trivets, two rolls of foil and a stack of containers for leftovers. Add those as claimable lines. Someone will take them, and they are the lines that save your evening.

• Plates, 1.5 per guest, because people get a fresh one for dessert.
• Forks, two per guest. Cups, two per guest.
• Eight serving spoons and four trivets.
• Two rolls of foil and one pack of takeaway containers.
• Two extra trash bags per ten guests, and a recycling bag by the drinks.
• A sharp carving knife and a board with a groove.

Running the sheet as a link instead of paper

Paper works if people are in one building. For a family spread across three towns, a link works better. On a Bringalong invite you add each item with its servings, share the invite link, and guests claim items from the same page where they RSVP. Claimed items show as taken, so nobody has to scroll a group chat to find out whether stuffing is handled.

Your private manage link shows the claims next to names, the Going and Maybe counts, plus-ones, dietary notes and a CSV export you can print and tape to a cabinet. For an office potluck, print the QR code from the invite page and stick it on the kitchen door so people claim a dish while they are waiting for the microwave.
