This creamy mustard chicken with baby potatoes is a simple one-pan dish with tender chicken and potatoes in a creamy mild mustard sauce.
The addition of potatoes to the casserole means that all it takes to make a complete main meal is a helping of green vegetables.

- Quick and Easy
- One Pan
- Family Favourite
- Only 550 Calaries per serving
This is the type of family dish I really like to serve midweek when the evenings are a little cooler. It is quick and easy to make and, of course, very tasty.
Despite its name, this dish is surprisingly low in calories and fat as I have used a low fat crème fraîche to give it its creamy taste and texture and then thickened it up a little at the end of the cooking time.

Economical chicken dish
I have used chicken thighs to make this dish. Not only are they more economical, but they also tend to have more flavour than chicken breasts. You could also use whole chicken thighs or a mixture of chicken thighs and drumsticks if you preferred.
Serving suggestion
Cooking the little salad potatoes in the casserole almost makes it a meal in one but I like to serve some green vegetables or carrots alongside.
Storeage/Left overs
Leftovers can be kept for up to 48 hours if you cool quickly and refrigerate after cooking. Keep in a covered container. Reheat over a low heat stirring frequently until piping hot.
Leftovers can be frozen for up to 3 months. However, if you are planning to make and freeze ahead, I would omit the potatoes as I find they tend to loose thier texture and become a bit watery when frozen. Simply boil until tender alongside reheating and add to the pan for the last 5 minutes or so.
