1 Syn Potato, Cheese and Onion Waffles | Slimming World

Since starting the Slimming World journey, there are a few things we miss. Hash browns, potato waffles and potato cakes are near the top of that list. So we decided we’d try making something to fill that gap, and these 1 Syn Potato, Cheese and Onion Waffles do just that.

For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

One standard shop bought potato waffle will cost you somewhere in the region of 3 syns. In my opinion savoury waffles should always be made with potato. Oats are for sweet waffles, and you can find all of our Waffle recipes here.

However, these work out at only 1 syn per portion, and that’s including the cheese….how good is that?!

You’ll notice that this 1 Syn Potato, Cheese and Onion Waffles recipe uses a tablespoon of Smash, but we wouldn’t consider this a tweak because you could make these with Smash rather than fresh potato if you wanted to. The small amount of smash is in there purely to absorb any moisture from the fresh potato. Were not using it to thicken, it’s being used as mashed potato.

This means that the only syns in this dish come from the cheese. Of course if you wanted to use part of your HEA allowance then you could make them totally syn free. We like to use our HEA on other things so we decided to syn the cheese. But as always it’s up to you how you use your Healthy Extra options.

These 1 Syn Potato, Cheese and Onion Waffles are great at any time of the day.

They’re really easy to make, and you can even prepare the mix in advance so all you have to do is pop it in the waffle maker whenever you’re ready. Why not try them with your Slimming World fry up?

There are a couple of things you will need to make these 1 Syn Potato, Cheese and Onion Waffles.
This post contains affiliate links. Find out what this means.

First, you’ll need a waffle maker. We use one of these as it’s SO easy to clean, which you can pick up on Amazon. This will easily make enough for 2 portions. Kay and I have big appetites, but we could only manage half of a waffle each with beans!

If you’re cooking for more you can pick up a double waffle maker on Amazon too.

You will also need a decent grater. Again, you can pick one up on Amazon pretty cheaply.

Finally, if you want your cheese to go that little bit further then you should try a fine or microplane grater. As always, you can get one from Amazon

When ever oil is called for in cooking we use Frylight instead. Perfect for everyday frying and cooking, it delivers exactly one calorie per spray, which makes it Syn free! The olive oil or sunflower versions are an ideal for this 1 Syn Potato, Cheese and Onion Waffles recipe. You could even try the butter flavour if you want a more buttery taste.

    1. Hi Nikki,
      Yes you can cook them in a silicone waffle mould. We tried this recently. We’ve added the silicone mould method to the instructions.

    1. Hi Charlotte,

      I don’t see why not. As long as you give it a decent spray with Frylight and don’t put too much of the mix in (or it may get messy!)

  1. As i don’t have a micro wave what other way could I soften the potatoe? Would it work by boiling in their skins till soft?
    I must be one of the few people without micro waves!!!

  2. Just bought a wafile maker,and made them completely with smash potatoe and grated cheese but they separated, like bRokeby in half,and i couldn’t get them out could you tell me please what I did wronge thankyou.

    1. Hi Beverley
      If you use all Smash rather than fresh potato it will have to be quite dry so it holds together during cooking

  3. I love these and am going to try to freeze the mixture as it is time consuming to peel the potatoes after having cooked them.

    1. Hi Cey
      The Smash is used to absorb any moisture from the potato, so you could use some flour instead, but you would have to adjust the Syn value acccordingly

  4. Why can’t I print your recipes? It always comes up with a red page saying “this website has been reported as unsafe”

    1. Hi Cat
      These are pretty straightforward to make. You can batch cook them and freezing shouldn’t be a problem. Ensure they’re cold and freeze them as soon as possible. Defrost thoroughly before reheating.

  5. I don’t see that these waffles can be frozen? I’d like to make batches of them and freeze them then bring them up to temperature in the oven. Is this not possible? I haven’t made one yet but thought I’d ask this question first. Thanks for helping.

    1. Hi Sue
      We haven’t attempted freezing these, so can’t give a recommendation. However, it would be worth a try. If you have a go, please let us know how you get on. 🙂

    1. Hi Corinna
      The recipe uses 2 potatoes, so for best results, I’d follow the instructions on the pack for the number of servings you think you’ll need. 🙂

    1. Hi Julie
      I suppose you could! We’ve had members of our Facebook group using various kitchen gadgets in creative ways! I’d use plenty of Frylight to prevent them sticking. Good luck!

  6. Made these today and my husband loved them. I’m going to do a batch for freezing and I’ll let you know. I didn’t have sash but used an extra potato and put an egg in to bind. Came out fine, though I did give extra time in the waffle maker.

    1. Hi Jane
      So glad you enjoyed them. Timings for waffle makers can vary, so it’s worth experimenting to get it right. 🙂

    1. Hi Cynthia
      Smash is a dried potato powder, which you can reconstitute with water to make instant mash. 🙂
      Thanks for getting in touch!
