How Much Mashed Potato Per Person?

As a guide, allow 200g of mashed potato per adult (normal appetite).

For creamy mashed potato, allow about 200g of raw potato per adult — roughly two medium potatoes — for a normal appetite. Once it’s mashed with butter and milk that makes a generous serving.

How much to make

• Light eater: ~150g each
• Normal: ~200g each
• Hungry / mash lovers: ~300g each
• Child: ~100g each

So for four adults, start with around 800g of potatoes. Mash is the kind of side people go back for, so if it’s a key part of the meal — a cottage pie topping, or bangers and mash — it’s worth making a little extra. Use a floury variety like Maris Piper for the fluffiest results.

How this is worked out

Mash is a moreish side, so allow about 200g of raw potato per adult — roughly two medium potatoes — for a normal appetite. It's easy to eat a lot of, so err generous if it's the star of the plate, and scale up for a crowd.
