Slow Cooker Chicken Casserole

Slow Cooker Chicken Casserole

Now it’s autumn it’s time to get back to basics with slow cooking, so I’m sharing my favourite recipe for slow cooker chicken casserole.

I use chicken thighs in my chicken casserole, as they have so much flavour and also stand up really well to slow cooking all day.

It’s easy to switch to chicken breast if you prefer though and they do also work well in this recipe!

Just make sure you don’t cook for more than 6 hours on low or chicken breast can go dry and a bit stringy.

How do you make chicken casserole in a slow cooker?

As I slow cook so many meals, I’ve got loads of tips on slow cooking to share with you.

This chicken casserole recipe is the result of a lot of tweaks as I’ve made it over and over again over the years, and improved it a bit almost every time.

  • Use sweet potatoes instead of normal potatoes
  • Chicken thighs on the bone add loads of flavour
  • Red lentils create a naturally thick sauce
  • Place the vegetables at the bottom of the pot
  • Brown the chicken thighs
  • Thicken naturally by adding a couple of tablespoons of plain flour

As potatoes often stay hard when you slow cook, I’ve replaced them with sweet potato.

Better for you, they also help to thicken the sauce as they cook and disintegrate, and don’t take so long to soften.

You still need to make sure you put the potato in the bottom of the slow cooker, this is a good way to make sure potatoes cook through and soften.

Next I brown off the chicken thighs in a pan, so the skin is golden. This makes them look much tastier I find!

Add herbs and seasoning too, so you have layers of flavour building up.

Next I add red lentils and stock. Red lentils are great as they help to bulk out the sauce, thickening it so you don’t need to use anything like cornflour or gravy granules but you have the basis of a thick sauce to start with.

Later once the chicken casserole has cooked down a bit and there is more liquid, I add a couple of tablespoons of plain flour which helps the sauce to thicken further.

Now just leave it to slow cook and do its thing! It will bubble away while you are at work/running errands/ferrying kids around, and creating a warming comforting dish you can eat straight from the pot!

Slow cooker chicken casserole is one of my autumn and winter go-to recipes.

What to serve with slow cooker chicken casserole?

Since it already contains sweet potatoes, vegetables (carrot and onion) and red lentils alongside the chicken thighs, this casserole is a filling dish on its own.

A bowlful served alone makes a filling meal already!

To make a family meal which will serve more people, I also like to serve with mashed potato, crusty bread to dip into the sauce, and steamed broccoli and peas.

Love this hearty, warming casserole Lucy, must try it soon! Thanks for linking to my beef casserole:-)

I love the idea of using lentils to help thicken the sauce, great hack. Thanks for including my Italian Sausage Casserole recipe.

This looks like a fabulous family dinner recipe. I love the idea of adding lentils – thicken the sauce and sneaky extra protein and fibre!

This looks like the perfect, warming mid-week meal!!! And love that you can leave it in the slow cooker so it’s ready when you come back from work.

This recipe is absolutely delicious Lucy! I made it yesterday in my Instant Pot but using slow cooker function and we all loved it! Used mixture of thighs and drumsticks and served it with buttered egg spätzle. Perfect autumnal casserole and so much goodness too! 🙂 x
