Triple Cooked Sweet Potato Fries

Triple cooked sweet potato fries
Triple Cooked Sweet Potato Fries make a delicious side and are a healthy way to feed your friends and family.
Sweet potatoes are full of antioxidants and lower in calories than regular potatoes – so they’re the perfect guilt-free treat (sort of).
These triple cooked sweet potato fries are a perfect side to serve with a simple slaw or anything from the barbeque or grill.
Even though we are a British website, we called these sweet potato fries so as not to confuse these with recipes for roasted slices of sweet potato.

Servings 2


  • 2 large sweet potatoes (peeled)
  • vegetable oil (to fry)
  • salt


  • Slice the potatoes into 2cm/1in thick chips/fries. If the potato is too long cut them in half.
  • Drop the chips into salted boiling water and reduce the heat to simmer. Boil until cooked.
  • The potatoes are cooked when a knife point slides in easily. Remove from the heat and drain.
  • Place the chips in a single layer on a tray lined with kitchen paper or a clean cloth, this will help to absorb the moisture, and leave to cool down before placing the potato in the fridge to dry out – this is best done over night. You can speed up the process by placing them in the freezer for half an hour or so.
  • Heat a fryer filled with vegetable oil to 140°C, drop in the chips and fry until they have a dry appearance – this will take about 8-10 minutes.
  • Drain the oil well and return to a tray, again lined with kitchen paper or a clean cloth. Leave to cool down and place back in the fridge for a couple of hours or cheat and use the freezer.
  • When ready to serve, bring the fryer back to 180°C, drop in the chips and cook until crisp – this will take about 7-8 minutes. Be careful not to overcook them as they will go very dark.
  • Drain again and sprinkle with a little salt before serving. 
Sweet potatoes are not always orange-fleshed on the inside but can also be a spectacular purple color.
