What is the cheapest way to feed 100 people at a wedding?

A buffet is usually far cheaper than a plated meal because you need less waiting staff and can serve crowd-pleasing food in bulk. Choose dishes that are cheap to make in large quantities, such as a big pot of chilli with rice, a pasta bake, a vegetable curry with naan, or a tray of lasagne with salad. You can buy ingredients in bulk from a wholesaler or supermarket, and ask family or friends to help cook ahead of time.

Another option is a baked potato bar with toppings like cheese, beans, tuna and coleslaw, which is very low cost and filling. Or hold your wedding at brunch or afternoon tea time, so guests expect lighter food like sandwiches, scones and cake, which costs less than a full dinner. You could also ask guests to bring a dish to share, which works well for informal weddings, but be clear about what to bring so you don't end up with ten bowls of the same thing.

Keep drinks simple too, like jugs of water, cordial and a few bottles of wine, rather than a full bar. And remember, a shorter reception with food served earlier means less need for a second meal later. Whatever you choose, make sure there is enough for everyone and that any dietary needs are covered.
