These mash volcanoes are a great way of getting the kids enthused about vegetables as they create the perfect lava eruption for dinner.


  • 300g potatoes (Desiree works well, but any creamy all-rounder would do)
  • 75ml milk
  • 20g-30g butter
  • 30g grated cheese (optional)
  • Salt and pepper
  • Ketchup ‘lava’
  • Additional veg to serve – broccoli ‘trees’ and pea ‘boulders’


  1. 1Peel the potatoes and chop into chunks. Put into a pan of salted water, bring to the boil and simmer gently for 15 – 20 minutes until soft and tender.
  2. 2Towards the end of the potatoes’ cooking time, cook the other veg that you’re using.
  3. 3Switch off the heat and drain the potatoes through a colander. Return them to the pan for a couple of minutes to dry off any remaining water.
  4. 4Put the butter and milk into a microwavable bowl or cup and heat briefly until the milk is warm and the butter is melted.
  5. 5Mash the potatoes, (or use a potato ricer) until they are smooth. Add the butter and milk mix, mash in and season to taste.
  6. 6If you’re adding grated cheese pop that in and stir through.
  7. 7Pile out half the potato mix onto each plate and smooth into a volcano shape.
  8. 8Make a well in the centre and add the ketchup lava then arrange the additional vegetables around the foot of the volcano.
  9. 9Serve immediately and be prepared for any eruptions!
