  • 175g Irish St Gall cheese, mature cheddar or gruyere, grated
  • 600ml double cream


  1. Heat oven to 180C/fan 160C/gas 4. Use a Japanese mandolin or sharp knife to slice the parsnips and potatoes very thinly. Layer the parsnips and potatoes in a shallow gratin dish, sprinkling some cheese and onion and a little drizzle of the cream over each layer, seasoning with salt and pepper as you go. The top layer should be potatoes and parsnips with a final sprinkling of cheese and drizzling of cream.

do you leave the core of parsnips in so they are roundly sliced? or do you still take the core out?

This is a wonderful dish and goes so well with the daube of pork and roast shoulder of lamb.

I substituted the St. Gall cheese for Gouda, used oat cream and topped the gratin liberally with fresh parsley. What a delight! I will definitely make this again.

I make this all the time as my default dauphinoise - much creamier than normal and properly delicious with the daube of pork as recommended.

Cheesy and good, though I may use less onion next time to let the other flavours come out more.
