Melt the butter in a medium saucepan and then stir in the flour to form a thick paste. Gradually whisk in the milk a little at a time, bring to the boil whisking all the time until you have a smooth but fairly thick sauce. Stir in the mustard and season with salt & pepper.
Put the sliced potatoes into a pan of boiling salted water and simmer for approx 10 mins until just tender. Drain.
Layer up the sliced potatoes and leeks with the ham in a shallow heat-proof dish, seasoning between the layers.
Pour over the white sauce. Lay the cheese on top, then bake in the oven at 200C, 400F, gas mark 6 for 20 – 25 minutes until the cheese has melted and is beginning to brown. Serve immediately.
Rich, creamy and warming this bake makes a delicious, indulgent side dish.
