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).
Table of Contents
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.

🥘 Cooking the Casserole in the oven
You can cook this chicken casserole recipe in the oven by placing the sealed chicken, sauce and veggies in a casserole dish with a lid on, and bake in the oven at 175C/350F for 45-60 minutes, until the carrots are tender.
Note: Add approx 120ml (1/2 cup) extra chicken stock to the mixture 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.

Incredible! Its now part of my favourites recipes… this was delicious a definite 10/10 anda big hit in my house with them going back for seconds !!!
Love this casserole such a comforting dish. Very grateful for all Nicky’s lovely dinner recipes. Can always rely on her. know it will be good food
This is hands down one of the best dishes I’ve ever made. My only complaint, and it has nothing to do with the recipe (which is perfection), is the website itself. I was following along on my phone, and the page jumps, causing me to lose my place, or it crashes. It made this relatively simple recipe difficult to make.
This was absolutely delicious! I also rarely comment, but this is a classic recipe. I baked mine in the oven. I also found it a little thin, but I did add some ‘sloshes’ of cooking wine 🙂 So I poured the sauce into the skillet after baking and added 2 T. flour. It thickened nicely into a gravy. Thank you for this!
