Cheesy Potato and Onion Casserole

READY IN: 2hrs 5mins
Recipe by Zoe4782

This recipe is originally from an old cook book of mine 'Vegetarian Cooking Made Easy' by Veronica Vezza. It's a really hearty and tasty dish. I like to add some mustard to the cheese sauce to give it some kick. Serve with cabbage and sausages.

Since we're a family that adores cheesy potatoes this was a good supper for us. I made this the other night when some comfort food was needed. This is a very good recipe, but it's only disadvantage is that there are no instructions how to make the cheese sauce. I've been cooking for a while and can make a roux, but beginner cooks will get lost here. Just to clarify things, to make the cheese sauce, melt the margarine (I used butter) in a sauce pan. Add the flour all at once and stir until it is completely incorporated into the margarine. Add the milk, and continue stirring all the time until the sauce has achived the desired thickness. Add the cheese and continue stirring until the cheese has melted into the sauce.
