Working out how much brisket per person to buy is trickier than most cuts, because brisket loses so much weight as it cooks.
A reliable guide is around 250g of cooked brisket per adult, which means buying roughly 500g of raw brisket each.
This guide explains the yield that catches so many cooks out, gives you clear kilogram tables for 4 to 50 people, and helps you buy the right amount whether you are plating it up or filling rolls.
The quick answer: brisket portions at a glance
Plan on 250g of cooked brisket per adult for a plated meal, or about 150g each when it is going into rolls and sandwiches. Because of the shrinkage, the raw weight you buy is roughly double that.
How you serve it changes the maths as much as appetite does. A plated brisket dinner needs more per head than a spread of pulled brisket rolls where bread does some of the work. The table below shows both, with the raw weight to buy alongside.
| Serving style | Cooked per adult | Raw to buy |
| Plated main | 250g | About 500g |
| Rolls and sandwiches | 150g | About 300g |
| Part of a mixed barbecue | 150g to 200g | About 350g |
Why raw weight is double cooked weight
Brisket can lose 40 to 50 per cent of its weight during a long, slow cook, which is why you buy roughly double the cooked amount you want to serve. Trimming, rendered fat and moisture loss all take their toll.
A whole brisket carries a thick fat cap and a seam of fat between the muscles, much of which is trimmed before cooking or renders away during it. As a worked example, a 4kg raw brisket yields roughly 2kg of sliced meat once cooked and rested, enough for about eight plated serves. Cooking low and slow is what makes the cut tender, and our guide to slow-cooking beef in the oven walks through the method.
How much brisket to buy for 4 to 100 people
To feed a crowd, buy about 500g of raw brisket per adult for a plated meal, then round up to whole briskets. The table below scales the raw buy weight and the cooked yield for common group sizes.
These figures assume a plated main. If you are serving rolls, you can drop to around 300g raw per head. Buying whole briskets is simplest, so round to the nearest one and enjoy the leftovers.
| Guests | Raw brisket to buy | Cooked yield |
| 4 | 2kg | About 1kg |
| 6 | 3kg | About 1.5kg |
| 10 | 5kg | About 2.5kg |
| 15 | 7.5kg | About 3.75kg |
| 20 | 10kg | About 5kg |
| 30 | 15kg | About 7.5kg |
| 50 | 25kg | About 12.5kg |
| 100 | 50kg | About 25kg |
Point vs flat: does the cut change the maths
The point renders more fat and pulls beautifully, while the leaner flat slices cleanly and yields a little more usable meat per kilo. Which you choose affects both the eating and the amount to buy.
A whole packer brisket includes both muscles, giving you the best of each but the most shrinkage. A flat-only piece is leaner and more predictable for slicing, so its yield sits at the higher end. The point is richer and ideal for pulled brisket rolls. Our guide to brisket point vs flat explains how they differ and which suits your cook.
Plates, rolls and leftovers
Sliced onto a plate, brisket needs about 250g cooked per person, but stuffed into rolls it stretches to feed nearly twice as many. Serving style is the easiest lever for making a brisket go further.
For a casual gathering, pulled or sliced brisket in rolls at around 150g each turns a single cook into a generous spread. Rest the meat before slicing so it holds its juices, as our guide on resting beef explains. Any leftover brisket keeps well, and freezing it is easy, as our guide to how long you can freeze meat covers.
Buying brisket in Australia
Buy a whole or half brisket by weight, allowing for the shrinkage, and order ahead for big cooks. Brisket is sold in sizeable pieces, so a little planning goes a long way.
Whole packer briskets typically run from 4kg to 6kg, feeding a crowd once cooked, while a flat piece suits a smaller family meal. For large gatherings it is worth buying more than one and freezing any surplus. When you are ready to order, you can browse the full range of cuts and have quality brisket delivered chilled, ready for a weekend low and slow.
Conclusion
The whole trick with brisket is the yield: buy roughly double the cooked weight you want, so about 500g raw per adult for a plated meal or 300g for rolls. Use the tables to scale for your crowd, choose point or flat to suit the cook, and freeze the leftovers. For quality brisket delivered, Cost Cut Meats makes it simple.
