Slow Cooker Honey Mustard Chicken is a simple and tasty meal that takes very little effort to make. With just a handful of ingredients, you’ll end up with tender chicken in a rich honey mustard sauce that’s full of flavour. It’s the kind of recipe you can throw together in the morning and look forward to serving with rice, mash, or vegetables at dinner time.

Chicken – Boneless, skinless chicken thighs work best in slow cooker recipes because they stay tender and juicy. Chicken breasts also work, but they cook faster and can sometimes be a little drier, so keep an eye on the timing if you’re using them.
Honey – I usually add 4 tablespoons for a sweeter sauce, but you can reduce this to 2 or 3 if you prefer a more subtle flavour.
Mustard – Dijon mustard gives the sauce the best depth of flavour without being overpowering. English mustard can be used, but it has more of a kick, so stick to Dijon if you want a smoother taste. Two tablespoons is usually enough, but add a little more if you like it stronger.
Spring Onions – Sliced spring onions add a mild flavour that works really well with the honey and mustard. If you don’t have any, a regular onion will do the job.
Garlic – Two cloves of garlic, crushed, bring extra flavour to the sauce.
Stock – Either chicken or vegetable stock works fine. I usually add 150ml, the chicken will release extra juices as it cooks, so you don’t need too much liquid to start with.
Cream (Optional) – Stirring in some cream towards the end of cooking makes the sauce richer and helps thicken it up. You can use either single or double cream, or leave it out if you’d prefer a lighter version.
Cornflour (Optional) – If the sauce is thinner than you’d like, a quick cornflour slurry will thicken it up nicely.
Vegetables (Optional) – You can stir in peas, broccoli, or even small chunks of potato. Add potatoes at the beginning, or softer vegetables in the last 15–30 minutes.
Making It
You can optionally sear the chicken first – I don’t tend to with slow cooker recipes (unless it’s sausages!) – but you can if you have a slow cooker sear model.

Make up the stock in a jug and stir in the honey, mustard and any seasoning (salt, pepper, garlic powder, etc, according to taste).
Place the chicken and spring onions in the slow cooker and pour the stock mixture over the top.

Half an hour before the end, lift the lid off to let the sauce thicken. If you are using cream, stir it in now. You can add in some peas or broccoli at this point too.
If the sauce is still runny, stir in a little cornflour slurry to thicken it up. The chicken can be served in whole pieces or shredded prior to serving.

What To Serve With Honey Mustard Chicken
This dish works with so many sides. Rice, noodles, or mashed potatoes are great for soaking up the sauce. Or, for an easy all-in-one meal, add new potatoes to the slow cooker at the start and let them cook along with the chicken. A side of green vegetables balances the sweetness of the honey sauce perfectly.
Can I Freeze Honey Mustard Chicken?
Yes, you can freeze it, but I would leave the cream out (if using) and stir that in when you reheat it. Leave it to completely cool down before storing in a freezer suitable container.

Hi Liana, me again!
Getting organised to do the recipe tomorrow but to be honest don't want the chicken to be shredded. Is this also going to affect the time?
Many thanks Janet x

Hi Janet- sorry, I forgot to answer this one! No, you don't need to shred it - just cook it as per the recipe and serve the chicken whole. I hope you enjoyed it!

Since I've got loads of chicken breasts in my freezer and you say they cook faster, what would the cooking time be for them please?
Ta much x

Hi Janet - I would say low for 4 hours or high for 2-3 hours - check they are cooked through, but this should be more than enough time for breasts without them drying out. Let me know how you get on!
