Worried you won’t have time to do all the Christmas cooking and roasting on the big day itself? Parboil and freeze your potatoes beforehand, then all you have to do is whack them in the oven for a crispy, crunchy, Christmas Day finish.


  • 2kg potatoes cut into large chunks
  • pinch of salt 
  • 100ml vegetable oil 

Top tip!

Choose potatoes that are best for roasting, such as Maris Piper or Vivaldi.


  1. Put the potatoes into a large saucepan and cover with cold water. Add a generous pinch of salt. Bring to the boil, then simmer for 6 minutes.
  2. Drain the potatoes in a colander, allowing them to cool completely. Shake the potatoes to rough up the edges a little, then tip them into freezer-safe food containers, allowing a little space between them to prevent them from sticking together. Freeze for up to 2 months.
  3. When ready to cook, preheat the oven to 220°C/Gas 7. Pour the vegetable oil into a roasting tin and heat in the oven for 3-4 minutes. Tip in the potatoes, turn to coat, and roast for approximately 55-60 minutes until browned and crispy.
