Slimming World Chips are a firm favourite in Slimming World circles and (although I do enjoy them) I was getting a little sick of seeing them on my plate! After a naughty visit to a pie-based restaurant in Cardiff, I realised that I could use the same method for some Syn Free Sweet Potato Fries

I actually prefer sweet potato chips for a few reasons:

  1. They taste AMAZING and have a wonderful texture.
  2. You never have to par-boil because they are naturally softer.
  3. They look so damn pretty!

You could have these with our Melt-in-the-middle Burgers and a big salad for a syn-free but naughty feeling treat! Or, you could try them as a side for some Meatball Marinara Sliders… DROOL!

Whenever we need to replace oil in cooking we use Frylight. Perfect for everyday frying and cooking, it delivers exactly one calorie per spray, which makes it Syn free! The Sunflower or Olive Oil flavours are ideal for this Syn Free Sweet Potato Fries recipe.

  1. Grab as many potatoes as you need/want. I tend to use 1 large- 2 medium per person.
  2. Chop your potatoes into chip shapes. (I am really OCD/lazy/wasteful and try to cut mine into a nice rectangle to make nice straight chips).
  3. Cover a baking tray with tin foil (me being lazy again, no washing up!) and spray liberally with Olive Oil Fry Light.
  4. Add your chips to the tray, spray with more Fry Light and shake over plenty of Schwartz Perfect Shake 'chips'.
  5. Bake at 180 (fan) for about 20 -25 minutes. Keep an eye on the chips as sweet potato does catch very quickly- turn the heat down and cook for longer if you need to.
  6. When the chips are nearly done, I like to spritz them with a little Garlic Fry light before returning them to the oven for the last few minutes.

    1. Hi Joan
      It seems that the nutritional calculator wasn’t dividing the total calories between the number of portions. This has now been fixed

    1. Hi Charlie
      We haven’t given these a freezer symbol, as we haven’t tried freezing them. I’m not sure how successful they’d be.
