Diet Coke Chicken

Diet Coke Chicken Pin

One of the good old Slimming World favourites thats name gets bandied around in Image Therapy, and usually, there’s at least one dish of this at the taster sessions. However, there’s an excellent reason for this. Quite simply, gross as its sounds, it’s delicious (I think it tastes like Reggae Reggae Chicken without the heat, others say like black bean sauce). And best of all? It’s syn free.

The first time I tried to make it, I accidentally used nearly a full bottle of Worcestershire sauce, and I forgot to add a stock cube. Although the result was really good, I don’t recommend that method!

A couple of things to note:

  • Make it your own. Want more chicken? Add more. More veg? Why not?
  • Bulk it out with loads of speed vegetables. I usually throw any bits and pieces in there I have, most things work well.
  • It’s super easy to make this vegetarian-friendly by either using Quorn or loads of veg and a vegetarian stock cube instead. Do note, that both Diet Coke and Diet Pepsi/Pepsi Max (and most other “diet” drinks) contain a source of phenylalanine, which depending on how strict you are as a vegetarian may count this out. “Full-fat” (regular) Pepsi works well but would need to be synned.
  • Some versions don’t use Chinese 5 spice and soy sauce which is very yummy too and doesn’t have the “Chinese” taste to it. I prefer it with them, but as always, do what’s right with you.
  • This dish can feel like it takes forever to thicken up. It goes from water to sauce consistency in a few seconds. Stick with it! It will thicken eventually.
  • This works well in the slow cooker (just throw it all together) but do be aware it will need to be pan cooked too, to thicken. The slow cooker doesn’t do that part. This dish freezes well too.
  • As always, I have tried to be accurate with Syn values; please check as these can change. Two minutes can protect your weight loss.
