The sauce recipe

 

Sauce Supreme

15g unsalted butter

15g plain flour

250g cold chicken stock

½ tsp Dijon mustard

200ml double cream

salt and black pepper

Melt the butter, take the pan off the heat, add the flour and whisk. Return to the heat and cook out the flour for 2-3 minutes, stirring continuously making a roux sauce – do not walk away.

Tip your cold stock straight into the roux and whisk until smooth, then cook on a low heat for 20 minutes. Season with salt and black pepper.

Add the mustard and the cream and simmer for 5 minutes.

You can freeze the sauce if it's more convenient – it's every bit as good from the freezer.

You have choices for your pie lid. I'm using the potatoes I've already baked and have stashed in my fridge.

You could use the ever popular puff pastry sheet, again taken from your freezer stash.

Add the mushrooms to the chicken and then fold through the sauce. Pour the filling into a casserole measuring 23x23 cms approximately or, in my case, a foil tray - layer the sliced potatoes over the top, add a little salt and pepper and a dot or two of butter . Place in the oven for 25 minutes and serve.

A perfect meal for when there's a chill in the air!
