Diet Coke Chicken

This is a classic recipe for Slimming World followers - it sounds really bizarre, but have faith, it turns into a really tasty barbecue-style sauce, and best of all it's FREE! I served mine with vegetable rice, but it would work equally well in a pitta bread, on a jacket potato or with Slimming World chips.

Serves 4

Syn free on Extra Easy and Original


400g sliced chicken breast

1 onion, diced

330ml can Diet Coke

6 tablespoons passata

Dash of worcestershire sauce

Fry Light

Salt and pepper to taste


  1. Heat a large saute pan and spray with Fry Light
  2. Add the chicken and onion and fry until beginning to colour
  3. Add the remaining ingredients and bring to the boil
  4. Simmer until the sauce thickens and reduces down to about half its volume - approximately 30 minutes

Being a veggie I keep on hearing about this and thinking - would the quorn filletts work - well now I've got the recipe, determined to give it ago and use tabasco rather than Worcestershire. Will let you know!

Just so you know, there's a vegetarian sauce that's even better than Worcester sauce IMO, it's called Henderson's Relish, and it's delicious!

danny, Wed, 22/10/2014 - 4:29pm

I think they would work, same texture sort of, try it i think it would work

Low Syn Life, Fri, 15/07/2011 - 7:53am

I'm sure it would work just great with quorn. I think you can get veggie worcester sauce too? The sauce gives it tang rather than heat - maybe a mix of soy sauce/hot sauce/mustard might be closer to the mark, or mushroom ketchup? Good luck with whatever you try!

Would this work without onion using carrot instead as my husband won't eat onion? X

dawn mason, Sun, 22/02/2015 - 11:42am

In a nutshell YES I am allergic to onions I use onion granules or crushed dried onion so there are no lumps of onion visible...it is the actual onion I cannot have not the taste.

This is amazing! So easy to make as well! My husband was kept in the dark until he finished (and slurped the plate clean) and was amazed it was coke! I actually made mine with the max version as oppose to diet as I had it in the cupboard. Definitely going to make it again!!

alex, Mon, 06/02/2012 - 12:48am

I added Mushrooms and an orange pepper, the whole family loved it.
They were surprised when i told them it was made with diet coke.

Carolyn O'Kane, Tue, 21/02/2012 - 5:51pm

I make it regularly now as my kids love it! Also heard that if you make it with Diet Tango you get a sauce that is more like a Sweet n Sour as opposed to BBQ. I've added mushrooms to mine (to bulk up on free veg) and generally serve it with either rice or potatoes and brocolli for a tasty free meal.
Making it for tonight's group 'taster' session as so many people pull a face when I mention I've cooked Diet Coke Chicken for tea. Hoping for a few more converts!

Georgenna, Mon, 16/04/2012 - 8:36pm

I made this tonight after seeing the recipe on this site. I substituted the chicken for strips of frying steak and added mixed peppers. Served with noodles. Lovely!! I have some left over for lunch tomorrow and will be having this again for sure! Thanks.

Amanda Messer, Tue, 29/05/2012 - 7:20pm

I'm so glad you said you substituted beef for chicken as I dont eat chicken and I bought the noodles and stir fry veg tonight to... I just need some fry light and I'm going to make it tomorrow for dinner. Thanks for the tip x

Raffaela Dewing, Wed, 06/06/2012 - 1:50pm

Made this last night, it was delicious, thanks for sharing

Sarah, Fri, 17/08/2012 - 9:18am

Am going to try this tonight with chicken and then i think i'll try using tango with pork to make sweet and sour.
I think maybe balsamic vinegar and a sprinkle of mild chilli powder may work well as a worcestershire sauce substitute as i make a syn free barbeque sauce using them with passatta

Barbara, Wed, 25/09/2013 - 6:46pm

How did the sweet and sour turn out with the Diet Tango?

Kelly, Tue, 11/09/2012 - 8:09pm

Just cooking mine now, serving with new potatoes.. I'm new to slimming world so yum yum. X

Denise , Tue, 08/01/2013 - 2:12pm

Hi just started slimming world and was thinking of making this tonight I have everything in already apart from passata is there anything else I can use instead.

Anonymous, Sun, 10/02/2013 - 2:05pm

You could use tin tomatoes instead

Laura, Thu, 10/01/2013 - 11:29pm

You can subsitute passata for tomato ketchup or puree. :)

Lela, Fri, 11/01/2013 - 8:38pm

Can you freeze this once cooked, as I am cooking for one!

Debbie, Thu, 07/02/2013 - 3:41pm

I make this with fanta zero and add a little Chinese 5 spice to it and it is so tasty! Makes it more of an authentic sweet n sour!

Anonymous, Sun, 10/02/2013 - 6:31pm

Has anyone tried it with Quorn? how was it?

Think i'm going to have to give this a go :)

kirsty, Tue, 19/02/2013 - 6:56pm

Just made this and was lovely I added a fresh chilli to it as we love a bit of heat ha x defo makin it again x

beckiboo, Thu, 21/02/2013 - 7:25pm

Just tried this recipe. Wow. It was fab. The other half found it a bit sweet so i put a little bit of marmite in when it was cooking. I also used a little garlic when the chicken was browning. I will be making this alot i think x

avril, Sun, 03/03/2013 - 10:26am

going to try the diet coke chicken tonight but was wondering could you freeze this , must say it does look yummy x

gemma gibson, Tue, 19/03/2013 - 1:13pm

im thinking this too? Making mine now!

chris, Thu, 02/05/2013 - 9:25pm

if you substitute passata sauce for tomato puree how much would you need to use so its not too sweet?

Lyn swindlehurst, Thu, 09/05/2013 - 7:04am

I add peppers and mushrooms too bit more sipped food. Lovely. Takes longer to thicken than you think though.

Philippa, Mon, 03/06/2013 - 3:56pm

Just had this for my lunch! Delicious! Added a tin of Chinese veg to the chicken and coke sauce for a BBQ type stir fry - polished it all off! Such a simple recipe but would never have thought of it! Thank you!

Gwen Mccalum, Sat, 20/07/2013 - 3:33pm

Making this nkw with pork and orange tango zero added some pepers gona have it with rice. Will b intresting 2 c if him in doors knows its slimming food x

Bev, Fri, 30/08/2013 - 2:43pm

I have slow cooked my beef already so would it be possible to make this using per cooked beef

marypont, Thu, 05/09/2013 - 12:15pm

Never tried this, may give it a go. Didn't know what passata was so I will get some tomato puree I think. I am cooking for one, but it sounds ok to freeze if I heat the chicken through thoroughly. (can anyone advise me differently). Could us free flow quorn, then I wouldn't have to freeze. Thanks for the recipe.

I love diet coke chicken. I found your recipe and another one on another site and combined the two. The other one said about putting leftover veg in the sauce but your sauce is less spicy (which is good for my family). Thanks for this :)

nathan, Thu, 24/04/2014 - 9:40pm

im not on a diet, but stumbled over this on google. i deviated slightly (added cumin seeds and a red pepper, and served with boiled baby new potatoes), and this went down a treat with my mates!

Dawktah, Sat, 31/05/2014 - 7:46pm

Holy dear god.
Is this a comedy site or something?


Diet sodas of all kinds (except Hansen's) contain the artificial
sweetener, aspartame. Aspartame becomes dangerous when heated,
converting to formaldehyde in the body.

Diet Coke's in most of the world usually have a label saying to avoid doing so.

So, please please PLEASE do not use diet cola, especially not for your kids.

Jen , Mon, 08/09/2014 - 4:04pm

Aspartame has been used in the United States since the early 1980s. It is now found in thousands of different food products. Aspartame is commonly used as a tabletop sweetener, as a sweetener in prepared foods and beverages, and in recipes that do not require too much heating (since heat breaks down aspartame). It can also be found as a flavoring in some medicines.

In the body, aspartame is broken down into phenylalanine, aspartic acid, and methanol. Methanol can be toxic in high amounts, but the amounts that result from the breakdown of aspartame is lower than with many “natural” foods. For example, drinking a liter of diet soda would lead to consumption of 55 milligrams (mg) of methanol, as compared to as much as 680 mg of methanol from a liter of fruit juice.

ryan scally, Thu, 10/07/2014 - 6:19pm

Im making this as we speak . I had it the other day and its georgus :)

Linz, Tue, 04/11/2014 - 10:18pm

Sorry I have read through comments and still unsure as to whether you can freeze? Any advice appreciated thanks :) ..... I have made a huge batch tonight and don't want any going to waste as it is amazing!!!

NanaNorma, Mon, 14/09/2015 - 11:50pm

can I freeze this recipe?

Linda, Wed, 16/09/2015 - 8:05pm

gorgeous - thank you!!

Liz, Sun, 25/10/2015 - 8:36pm

I made this for my flatmate, seems to be a hit. I will definitely be making it again as its cheap enough for my student budget

dell, Sat, 23/01/2016 - 3:16pm

Could you make this in a slow cooker instead?

Julie , Sun, 03/04/2016 - 8:22pm

I can't eat peppers what can I substitute these with.

Sheila, Tue, 05/04/2016 - 8:50am

Can you use Passata with basil. ? As that's all I have at the moment

Holly, Fri, 06/05/2016 - 12:58pm

The rice looks amazing is there a recipe for that too somewhere??

Amy, Tue, 17/05/2016 - 12:36pm

Can I use coke zero instead of diet coke
And what can I use instead of sugar snap peas

Anonymous, Mon, 12/09/2016 - 5:54pm

I used mangetout in mine instead of sugar snap peas. They aren't essential anyway.

Yes it can be frozen.

I didn't have any peppers in so used mixed frozen vegetables. Also, I'm sure the passata with basil will be fine. I didn't have passata or tomato puree in and used a tin of chopped tomatoes instead and it still came out divine.

Anonymous, Mon, 12/09/2016 - 5:58pm

Any low calorie coke or cola such as coke zero should work as the original recipe on slimming world says 'diet cola'

Anonymous, Tue, 13/09/2016 - 11:17am

Yes it does freeze. Have done so many times and it's never let me down. Make and enjoy.
