Chicken, Bacon, Leek and Mustard Casserole

With just a few simple ingredients, you can create a lovely chicken casserole style dish. Leek is the star in this dish. It’s a fantastic seasonal vegetable, which is packed full of nutrients and antioxidants – perfect to keep those winter sniffles at bay. Combine that with the rich flavours of bacon and mustard and you’ve got a lovely winter warmer for dinner!

This dish requires a little work upfront in the pan, to saute the onions, brown the chicken and bacon and bring together the reamining ingredients. We use chicken thigh in this recipe, which is rich in flavour, but you could swap this out for leaner chicken breast.

Serve on top of a bed of creamy mashed potatoes, spoon over the liquid from the slow cooker and enjoy!
