Diet Coke Chicken

Slimming Eats Diet Coke Chicken - gluten free, dairy free, Slimming World (SP) and Weight Watchers friendly

I used to make diet coke chicken quite often when I was doing the Weight Watchers diet a few years back. The original recipe requires ketchup, but to make it as low syn as possible. I substituted the ketchup for tomato paste. I think it works just as well.

This recipe has been hugely popular since I first posted it back in 2009 (wow that’s a long time ago)

Since making various healthier changes to my diet. Whenever I make this, I  now use a diet coke that is sweetened with stevia instead of aspartame, as I try to avoid artificial sweeteners where possible and aspartame is really not supposed to be heated to high temperatures. Also if you prefer you can use the regular coke which makes the entire recipe is only 7 syns, which divided by 4 – would mean a serving would still on be approx 2 syns (which is pretty reasonable).

This recipe also works well with some pork shoulder (any visible fat removed)

    Hiya – your SW chips look gorgeous – do you do anything different to them ?



  • britmumincanada

    hey, I think the type of potatoes I have been buying help, as they are really sweet and yummy tasting. They are called Yellow Golds, not sure if you can get them in the UK, but they don’t come in huge potatoes, more a medium size and look kind of like large new potatoes.

    I parboil them for about 10 mins. Then drain off the water and put them back on the hob, just to dry off any remaining water. Literaly a couple of seconds.

    Preheat the oven to 200c or 400f.

    Spray a baking tray with non stick spray and spread the chips out on the tray. Sprinkle with some salt over the top (I think this is one of the things that really helps crisp them up and you don’t need to add any more salt to them afterwards). Then spray some non stick spray over the top of them and bake in the oven. Make sure you turn them regularly.

  • Hey
    Thanks for this website, there’s so many gorgeous ideas!

    About this recipe, do you use brand name Coca Cola or the cheapy stuff? I just tried to make it now and the sauce didn’t seen to be going sticky. It’s in the oven now, so hopefully it will be fine!

    This was brilliant, the only problem i had was the sauce sticking and burning to the tray, might try using foil next time (saying that i just noticed i should have used a dish… whoppps!)

    which brand of diet coke did you use?

    did you cook the sauce on a high heat on it’s own until it reduces down? This is when it starts to thicken and go sticky and you can then add to your chicken etc as a marinade.

  • I love this recipe, for my version though I add peppers, onion, worcestershire sauce and chinese 5 spice to the diet coke before reducing

  • excellent idea

  • excellent idea

  • i love the flavour coke marinade gives to meat


  • Absolutely gorgeous! Very weird though, it was watery for ages and then suddenly just reduced! Lovely sweet BBQ sauce.

  • am making this tonight , never had it before 

  • How long do you cook the legs for before you add the sauce

  • slimadmin

    about 15 mins, as soon as your sauce has thickened add it to the drumsticks.

    Diet Irn Bru works as well instead of cola – tastes a bit like Sweet n Sour!
