Sausage and Leek Casserole Recipe


Sausage and Leek Casserole Recipe

You can serve this sausage and leek casserole recipe with mashed potatoes or mashed carrot and turnip and these can easily be prepared once the casserole is in the oven. However, as I’m a big fan of one-pot-cooking (less washing up!), I’ve just added a few new potatoes to the casserole.

You can leave the casserole in the oven for longer if you wish – up to about an hour and a half would be fine.

If you’re after a delicious winter warming meal for four and you’re on a tight budget, this will work out at under £5.
