A warming delicious slow-cooked chicken casserole with fall-apart meat, lovely veggies and a seasoned creamy sauce.
Most of the work is done in the slow cooker, so you can look forward to a hearty family dinner when you get home from work.
Serve it with mashed potato to soak up that delicious sauce. The king of comfort food.

Nothing says Autumn more to me than getting the slow cooker on and making a creamy casserole that's spooned over a big pile of buttery mashed potato.
(excuse me a moment whilst I do some Homer Simpson-style drooling).
This one, with slow-cooked chicken thighs, tender baby carrots and little button mushrooms is divine.
The chicken pulls apart beautifully, the rich sauce has a very slight lip-smacking tang from the hint of lemon juice and the veggies soak up that sauce, so you'll find yourself marvelling at how good a carrot can actually taste.
📋 What do we need?

Ingredients swaps
- I love to use chicken thighs in casseroles, as they're more tender and stand up well to slow cooking. They also shred up beautifully. However, you can swap out the chicken thighs for chicken breast, or even bone-in chicken pieces.
- Add in extra veggies - such as baby potatoes, leeks, shallots or cubes of butternut squash.
- Add crispy bacon or pancetta at the end of cooking for am extra hit of flavour.

Add approx 120ml (½ cup) extra chicken stock when making the sauce, as liquid evaporates more in the oven.
Also, check and stir the dish a couple of times when cooking in the oven. Nutritional information is approximate -based on 4 servings WITHOUT the serving suggestions of mashed potatoes and green beans

Made this tonight and was absolutely delicious! So easy. So yummy. Whole family loved it. I used garlic powder as I had no celery salt and I think it worked beautifully. Thanks the yum-Yuma!! x
Cathy says
Was a great dish made for my parents recently. We doubled the recipe and made just a few modifications:
- added some canned kernel corn close to end of cooking time-adds some nice sweet crunch
- thickened a bit more by blending in some cornstarch with the cream close to end of cooking.

Lovely creamy sauce and nicely cooked meat and veg. perfect for a rainy day. I followed the recipe to the letter except for adding in some fennel seeds which give a nice contrast to the other flavours. Served with mash and steamed curly Kale and Spinach. Delicious. Dead easy to make. I'm learning not to leave things in the slow cooker for too long so 3 and a half hours on high was perfect,
Mimi says
I completely veganised this recipe, using vegan "chikn" pieces, vegan cream etc, and it was still absolutely to die for! I serve with either green beans or tender stem broccoli, and vagen mashed potatoes. I cooked it entirely on the stove in a big skillet and it worked very well. Enjoyed by all the family, and has become a regular meal in our house! Thank you! 🙂
Ashleigh Bright says
Can I leave out the celery salt if I’m not adding celery?
Mimi says
I've never used celery salt as I live in UK and it's not readily available. Wouldn't have thought it makes too much of a difference, it's still delicious.

Delicious! I often find that I have to alter recipes due to not enough taste and/or not fully cooked but this is my 4th KS recipe and they have ALL been extremely flavorful and cooked to perfection! Highly recommend any KS recipe!
Jadz says
My first slow cooker meal and it turned out perfectly. I'm not much of a cook and regrettably don't enjoy it at all. That said I don't have a chef fairy!
My biggest problem is long periods of standing as I have a spinal disability. All things considered this is my best cooking experience to date. Thank you for making everything precise and concise, I found your process made things much easier than the others I've attempted. Looking forward to trying another recipe very soon.

Saw this on YouTube and my wife made it along with green beans and mashed potatoes today for supper. It was exceptionally good. Perfect meal for the end of a chilly day here in Georgia. Thanks
Sally says
I made this tonight stove top method
It was delicious, I added small cubed potatoes and a leek too.
Will definitely be making this again.
Lisa says
Beautiful flavour. Quite easy to make. Would highly recommend
Whitney Mullenax says
This was PERFECT. I didn't eat it with anything else because I was afraid it would take away from all the goodness. I will totally make this again.
Nicky Corbishley says
Thank you Whitney 🙂
Alison says
There is cream in the ingredients photo, but not in the recipe. Was this an omission in the recipe? Looking forward to trying it.
Alison says
Oops - never mind. I see it now. Thanks!
