Place a layer of sliced potatoes in the bottom of a buttered casserole, (or use large cooking pot) add a layer of sliced carrots (optional are parsnip turnip) and corned beef, then fill up with more potatoes and chopped onions cover with Stock and Season well cook in a moderate oven for one hour with the lid on. (Or on a simmer ring for 30 to 40 minutes.) Remove lid and return to oven to allow top to brown for fifteen minutes approximately. Serve hot (optional again with vegetables).

This can be made in a large pan too simmer when boiling for 30 mins or more. Or another option my other half takes a large caserole dish (with lid) sliced potatoes a tin of carrots, one sliced onion, a tin of corned beef, and slices them all into the casserole dish then covers them all to just over the top with a beef gravy mix (or stock). She cooks this at Gas 5 that's 190 for a good hour or hour and a half. It's nice indeed
