Delicious Rich Diet Coke Chicken - a popular dish that the whole family will dig in and enjoy!!

Diet Coke Chicken
Many many years ago, I would regularly make this sweet tangy Diet Coke chicken. It was a popular dish when I was following the Weight Watchers plan.
The original recipe uses ketchup or sometimes even soy sauce. But is loved by many because of the tender braised pieces of chicken you get from that delicious sauce.
So back in 2009, I just had to adapt the recipe, to my own Slimming Eats version.
The easiest switch was substituting ketchup for tomato paste. I recommend tomato paste (or puree as it's known in the UK), rather than passata because otherwise, you will end up with a sauce that doesn't reduce down as well into the lovely thick sauce you see here.

Diet Coke Chicken or Diet Pepsi Chicken
You can use either pepsi, coke or a store own brand, doesn't need to be specific, either will do the same job.
But what if you like to avoid items that contain aspartame? Most diet drinks, unfortunately have it as an ingredient, there are some that use stevia, but hard to source those everywhere.
So if you would rather use regular cola for this popular recipe, don't be scared to make the switch.

What type of Chicken in Diet Coke Chicken?
Chicken thighs are definitely my preferred cut of chicken I like to use in this Diet Coke Chicken recipes because then stay nice and tender in this method of cooking the chicken.
By all means use chicken breast, if that's what you prefer, but just bear in mind the best results are with chicken thigh as recommend for this recipe.
Don't fancy chicken at all, then piece of pork will work in this recipe also. I use pork shoulder chops, that I remove from the bone and trim any visible fat. They are cheap cuts and are great for this method of cooking.
Diet Fanta Chicken
Many have swapped the cola for something like diet fanta or tango instead, to make a more sweet and sour style dish. It's a great way to get different flavours.

Why is my sauce not thickening for the Diet Coke Chicken?
If your sauce is not thickening then there is a few things to check, have you definitely use tomato puree (paste) and not passata?
Tomato puree is concentrated and much thicker and is what is used in this recipe, passata will not yield the same thick sauce as you see in these pictures.
The other thing to check is that your heat is not too low, you don't want it boiling constantly, but you also don't want it to be just at a simmer, as the sauce will not bubble enough to reduce down. Once you get it to boiling, you want to reduce the heat to medium-high so that it still bubbles away, don't add a lid as that will make it take longer to reduce. If you are worried about the splatters, one of these splatter screens for you pan are perfect.
It really does not take longer than 20 minutes for this sauce to reduce and thicken, so if it's taking longer, you have the heat too low.

Slow Cooker Diet Coke Chicken
This recipe also works well in a slow cooker for a pulled chicken or pulled pork recipe. I recommend adding in some smoked paprika for that smokey flavour.
As you are not doing the reducing down method as on the stove, If you want the sauce really thick, you can take out the pork or chicken once cooked, shred it with two forks and then add the sauce to a saucepan to reduce down to thicken. Before mixing the sauce with the shredded meat. Perfect!!
Or placing the lid slightly ajar for the last hour works too.

Sides for Diet Coke Chicken?
We love this with my Perfect Oven Baked Chips or just plain rice. If you would rather serve this with a veggie-packed option, you could also go for this Roasted Cauliflower Rice or Egg Fried Cauliflower Rice instead for a healthy alternative.
Vegetables for Diet Coke Chicken
I always prefer to cook my vegetable separately for this and not in the sauce, the sauce is pretty sweet and bbq like, so adding the vegetables into the sauce just makes a plate of food that is too sweet overall.
Cooking the vegetables separately also ensures they are not overcooked and you can actually taste the yummy vegetables.
Some of my favourites to serve with this are:
- Roasted or sauteed broccoli
- Sauteed zucchini (courgette)
- Peppers and onions
- Mushrooms
- Stir Fry Mix
I just cook in a little cooking oil spray with some basic salt and black pepper.
- or a simple mixed salad is perfect too.
Of course, if you are fussy about vegetables and prefer them in the sauce, there is nothing wrong with adding them into the pan with the chicken.

Diet Irn Bru works as well instead of cola - tastes a bit like Sweet n Sour!
Sandra Webster says
I made this tonight, but used regular coca cola, as like you, I avoid stuff with aspartame and like you say it isn't many syns when divided up. I served it with salad and syn free chips and everyone loved it. Thank you so much. I will definitely make this again.

Heidi Sneddon says
This is incredible. Cant get enough. This didnt serve 4 ppl though. It was too good to share. Lol
Anna nuttall says
Are you able to use Pepsi Max instead of Diet Coke?
Shevy (Slimming Eats) says
yes you sure can.
Michelle says
I’m gonna attempt this to try , can I add onions and peppers at beginning as I’m doing in slow cooker whilst I’m at work ?? Or is it best just to have chicken and the ingredients thats listed ??
Danielle says
What changes do you need to make to do it in the slow cooker? I’d love to do it as a pulled chicken style dish in my slow cooker but not sure about quantities & timing?
Shevy (Slimming Eats) says
you would definitely need to reduce the liquid, as it won't reduce down like on the stove. I would do about 2 hours on high or 4-6 hours on low.
Shevy (Slimming Eats) says
yes you can, also be aware if doing in the slow cooker you will need to reduce the volume of liquid, or add sauce to pan and simmer until thickened once cooked.
Karen says
I use diet fanta. 5 spice instead of Italian seasoning and add fresh pineapple at the end of cooking...sweet and sour.
I've also used Dr pepper when I didnt have any coke .
Janette says
Love your Diet Coke chicken so easy to make also a winner with the other half so glad I made this.
love this sight.
Janette says
Love this thank you great recipes.
Sam says
I’m making this shortly, can I use passata instead of tomatoes purée?
Shevy (Slimming Eats) says
no it must be paste (puree) - passata will result in the sauce being too watery.
Jenna says
Oh my god. I have just made this, it is absolutely delicious. So much nicer than the original slimming world recipe. The sauce is gorgeous I could just eat it off the spoon.
Siobhan (Slimming Eats) says
so glad you enjoyed it. 🙂
Honor says
Hello !
Could I use tomato ketchup instead puree ? I could maybe omit the balsamic vinegar to avoid it being too acidic ?
Thankyou for sharing !
Siobhan (Slimming Eats) says
You can just be sure to adjust syns/points for whatever plan you follow.
Natalie says
Does the chicken need chopping/browning at all? X
Siobhan (Slimming Eats) says
nope chicken goes in raw as per the recipe, if you want to slice into smaller pieces you can, but I just put the boneless chicken thighs in as they are, stay nice and tender as bigger pieces.
Paula Chester says
Made this in the week , absolutely delicious, thank you for the fantastic recipes , use your ideas everyday to meal plan x x
Marie Scott says
Hello, Do you think that Diet Ginger Coke would work in this or would the flavours clash. Thank you.
Ian morris says
My go to recipe every time I make it the diet coke chicken gets better every time
Emma says
When making this recipe with Large Chicken Thighs, how do I adjust this recipe?
Do I need to fry the chicken thighs beforehand or simmer for longer?
Siobhan (Slimming Eats) says
shouldn't make much different the size of the chicken thighs, but if they are really big, just slice in half.
Heidi says
This was really delicious and moist, it was a huge hit in our house and low in WW points for me. Served with jasmine rice and roasted peppers and onion. This one’s a keeper!
Greg says
Made this tonight, absolutely delicious. Thank you.
Milly says
Hi,
I only have cherry coke in the house….would that be too weird to use?
Siobhan (Slimming Eats) says
no it should be fine, enjoy!!
