This recipe is taken from the Jan/Feb 2016 issue of the Slimming World magazine and is a firm SW favourite. I’m actually surprised we haven’t tried this one before now as I have seen various recipes for it everywhere and we’ve heard so many people at group talking about how nice it is.

I think perhaps it was the idea of pouring a can of diet coke into your tea that had put us off before, even though we were incredibly curious. I couldn’t actually imagine how it would taste, we had big reservations about putting it with mashed potato and almost went with rice as it didn’t seem to make sense, but boy were we surprised when after the first taste we all agreed it was absolute perfection!

I am a big lover of mash so I was over the moon that it worked so well and added a dollop more to my plate, to the chagrin of my partner Rob who was already eyeing up my last chunk of chicken!

Tip 1 : Use a big pan for this one as there is a lot of liquid to add.

Tip 2: When straining the potatoes after boiling be sure to let all of the steam off before you add your seasoning and other ingredients. This will put a stop to soggy mash!


  1. A bit of prep to start… cut up the chicken into strips and dice the onions and peppers.
  2. Spray your pan with low calorie cooking spray and place over a high heat.
  3. Add the chicken, peppers and onion and fry for around 5 minutes or until browned all over.
  4. Add the diet coke, stock, passata, tomato puree, garlic, worcestershire sauce, soy sauce, mixed herbs and stir well.
  5. Bring to the boil, stir, cover and reduce the heat to medium/low. Leave this to simmer for 15 minutes.
  6. Stir in the sugar snap peas and turn the heat up to medium/high and cook for another 15 minutes.
  7. Check the chicken is cooked thoroughly and that the veg is nice and tender.
  8. Add a couple of cheese triangles to the mash as well as a good grinding of black pepper and some sea salt to give it an extra kick of flavour!
  9. Serve and devour!


We all absolutely love this one and will be making it one of our regular weekly meals! As an added bonus it also contains 3 lots of speed food so perfect if you are having a speed day too. The only change we made to the recipe was to add a couple extra light cheese triangles to the mash to give it a bit more taste.

We also thought the sauce would have been a bit thicker and stickier and after doing some reading it seems that others have found the same. The general consensus seems to be that to get it to thicken up you need to let it boil rapidly during the final stages of cooking.

As I said the portions were very generous for 4 people and there was a lot left over which I was happy to finish off! Please, please, please give this one a go as you won’t regret it!

If anyone has any alternative diet cola chicken recipes I would love to hear them and any other ideas you may have about what to serve it with. You can leave me a comment below!
