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.

🔪 How to make this chicken stew

✎ Notes

Make-Ahead:

You can make this dish ahead, then cool, cover and refrigerate for up to 2 days. Heat through in a large saucepan for 10-15 minutes on a medium heat until the chicken is hot all the way through. Add a splash of cream or milk if needed to loosen it up.

Freezing:

Make the casserole, then cool, cover and freeze. Defrost thoroughly in the refrigerator. Heat through in a large saucepan for 10-15 minutes on a medium heat until the chicken is hot all the way through.

  • 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.

How to scale up and scale down this recipe

You can double this recipe with no change needed to the ratios.

If you would like to halve the recipe, just halve the amount of chicken and vegetables, keeping the quantities of everything else the same. The casserole needs the amount of sauce in this recipe so it doesn't dry out.

Can I cook it in the oven instead?

Yes, you can cook in a casserole dish with a lid on, in the oven at 175C/350F for 45-60 minutes, until the carrots are tender.
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.

    Perfect casserole to keep out the cold wet weather. Doubled up so I’ve got lots to freeze.
