Why You Will Love It
- No prep - There is no need to brown the chicken first. You just dump it all in and turn it on.
- A delicious way to enjoy chicken - We love using chicken breasts because they are protein packed and versatile. However, we can get a little bored with eating them the same way all the time. This is an easy and delicious way to use them.
- A great way to use up lots of tomatoes - Growing lots of tomatoes? This uses lots of fresh tomatoes and makes sure that nothing goes to waste.
- Perfect for using the slow cooker in the summer - Nobody wants to turn their oven on on a hot summers day. The slow cooker doesn't heat up the kitchen like the oven does.
Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Chicken - Skinless and boneless chicken breasts are what make this a lean and protein packed meal. You could swap them for chicken thighs if you prefer.
- Oil - We used olive oil, as we find this has a nicer flavour.
- Balsamic vinegar - This is the star of the dish, so try to buy the best quality you can as you will really taste the difference. Cheap balsamic tends to be really runny too, which makes for a watery finished dish.
- Garlic - This balsamic chicken is garlic heavy, and that's just how like it. If you aren't a huge garlic fan, then feel free to reduce the amount used.
- Onion - We used red onion, however you could swap it for a brown onion, or even shallots.
- Tomato - The key to having a really delicious dish is to use fresh and ripe tomatoes.
- Basil - Fresh basil is always best in this dish.
More ingredient substitutions and variations can be found in the recipe card.
How to Make Slow Cooker Balsamic Chicken

- Step 1: Put the sliced onion at the bottom of the slow cooker.

- Step 2: Put the chicken breasts on top with the olive oil, salt and pepper.

- Step 3: Add the tomatoes, garlic and fresh basil.

- Step 4: Pour the balsamic vinegar on top.

- Step 5: Cook on high for 6 hours or low for 3 hours.
Serving Suggestions
We served ours on top of spaghetti with a green salad on the side, but you could have so many different things with it.
For a low carb option, serve it with courgette (zucchini) spaghetti or for more of a comforting dish then mashed potato is the way to go. You can serve it with spaghetti squash, udon noodles, couscous and of course just a big pile of vegetables or on a green salad.
We also like to crumble some feta on top just before serving, because the creaminess goes really well with the sweetness of the balsamic.
Leftovers are delicious on rice or a baked potato, or even just on a big green salad.

Storage
Store: You can keep leftovers in an air tight container in the fridge for 2-3 days.
Freeze: This recipe serves 4, but you can easily double the batch and then freeze the leftovers (with rice) in individual portions. Just make sure it cools fully before freezing. It will keep in the freezer for up to 3 months.
Defrost: Defrost it in the fridge overnight.
Reheat: To reheat, add it to a pan and heat on low, stirring often, until it is piping hot. You can also reheat it in the microwave.
Dannii's Top Tips
- We serve the chicken breasts up whole, but you could shred or slice them before serving and that would soak up a lot of the liquid too.
- We used skinless and boneless chicken breasts to make this dish, but you can use thighs or legs instead, but cooking times will vary.
- Either serve with with spaghetti, mashed potato, rice or on top of a green salad.
- Add a pinch of red chilli flakes if you want to add some spice to this.

Frequently Asked Questions
Yes, you could make this slow cooker balsamic chicken with boneless and skinless chicken thighs instead of chicken breast. It would change the nutritional information, but the chicken would be much juicier.
If you don't have a slow cooker, then this can be cooked in the oven. You can put everything on a pan with some extra vegetables like par-boil potatoes, peppers, mushrooms and asparagus and put in a preheated oven at 200°C/180°C(fan)/400°F/Gas 6 for 25-30 minutes or until the chicken is cooked through.
By looking at the ingredients, it doesn't look like there is much of a sauce to this. But that is the beauty of this dish - its simplicity. There are no thick and heavy sauces, just the juices from the chicken and tomatoes, mixed with the balsamic, garlic and basil.
There is a fair amount of liquid in the slow cooker bowl once it is cooked, but I find that once it is all mixed into the spaghetti and the chicken on top it is just the right amount. You can always use less of the liquid if you find it too much. I wouldn't recommend using a tin of tomatoes, as they are too juicy, so fresh is best.
There really is no rule here, just make sure that the beef joint you are using can fit in your slow cooker. We use a Crock Pot Slow Cooker and we love it. What I love most about it is that you can put the bowl insert on the hob too. You can also sear the meat in it first. I also love that it has a clear lid, as I am so impatient that I want to keep looking and seeing what it is doing. If you don't have a clear lid, then lifting it to see will release lots of the heat and add to the cooking time.
The best way to ensure that it is cooked through is to use a meat thermometer. Chicken is cooked when it has an internal temperature of 75°C/167°F.

This chicken looks really tasty. My favorite things in autumn are warm blankets, drinking hot chocolate. And I love snow too! In UK you can't see too much snow, that's why we're going back to Hungary every November or December... always snowing, and there is big big snow. :)

Hey Dannii!!
I'm an autumn lover...but not a winter lover :( So starting last year, autumn has just made me nervous. IT doesnt help that our house does not have a heater..so we kinda sorta totally freeze all winter.
Thanks for the recipe, how do you come up with so much awesome stuff?
Tamzin says
Yum sounds delicious! I was actually only saying to Dale earlier we have to use the slow cooker more this autumn and winter, I love this change of season but I am not that keen on snow!
