How Much Meat Do You Need for a Sunday Roast?

Roast portion guidance from our butchers: raw meat per adult for beef, lamb, pork and chicken, plus tips for feeding a crowd.

The short answer

Allow around 300g of raw boneless meat per adult and 150g to 200g per child for a Sunday roast, or around 450g of bird per person for a whole chicken.

Portioning a Sunday roast trips people up in both directions: too little and someone goes hungry, too much and you are eating roast beef for a week. Here are the numbers we give customers at the counter.

How Much Meat Per Person

RoastPer adult (raw weight)Notes
Boneless beef, such as topside300gSliceable, little waste
Bone-in beef ribs400gThe bone adds flavour
Lamb leg300g to 350gOn the bone
Pork joint, bone in350g to 400gCrackling needs a decent joint
Whole chicken450g of bird per personA 1.8kg bird feeds about 4 generously

For children, allow around half an adult portion. If you love cold cuts on Monday, add another 10 to 15 per cent to the joint.

Feeding a Crowd

For bigger gatherings, a hamper does the portion planning for you: see our meat hampers, including the family hampers. A whole English lamb leg or a topside roast makes a proper centrepiece.

Planning the Rest

Roast timings vary by cut, so it is worth checking a guide for the joint you choose, and remember to rest the meat before carving. Leftovers should be cooled quickly and used within a couple of days, which is where our leftover roast meat ideas come in.

Browse the beef, lamb and pork counters for joints, or ask us at the counter on The Oval.
