FIELD NOTES / planning
How much meat should you buy for a BBQ?
Choose an explicit portion allowance, split it across the menu and avoid buying a full portion of every meat for every guest.
Work out a total allowance for each guest, then divide it across the dishes. Buying a full allowance of burgers, sausages and chicken for everyone can quickly turn three menu choices into three dinners per person.
There is no single amount that suits every BBQ. For context, cookware maker Fissler suggests 150–250 g of meat per adult and 80–150 g per child, with sides. Weber's party guide gives a more generous 350 g per person. These are hosting estimates, not nutrition targets or guarantees of appetite.
Make the assumptions visible
Ask how many people want meat and how many want a vegetarian main. Consider whether the BBQ is the whole meal or one part of a longer buffet. Choose an allowance that fits those answers, rather than using the upper end of every estimate.
For a simple boneless shopping example, 10 adults at an assumed 250 g each gives 2.5 kg in total. If you allocate half to burgers and half to another boneless main, that is 1.25 kg for each dish. The total remains 2.5 kg; it does not double because there are two choices.
The BBQ cook planner makes the portion assumptions visible so you can adjust them. When buying bone-in cuts, ask your butcher about the particular cut's expected edible yield instead of assuming a kilogram is all meat.
Turn weight into a practical order
Use the pack or butcher's stated weight to translate kilograms into individual pieces. Decide whether everyone needs one of each item or whether you are offering a choice. Keep dietary alternatives clearly separated in the shopping list and cooking plan.
Do not buy extra simply because leftovers sound convenient unless you can chill and store them safely. Read the FSA's cooking and leftovers advice; for foods that need cooking through, its options include a core of 70°C (158°F) held for 2 minutes.
The arithmetic applies throughout the UK. Food Standards Scotland provides separate cooking advice for Scotland; the FSA covers England, Wales and Northern Ireland.
