What is the difference between a Stew and a Casserole?

I am a big fan of stews and casserole, but what is the difference between these two very British cooking concepts? Does it matter? Well, probably not, but generally if it is cooked in the oven I call it a casserole and if it is cooked in a saucepan I call it a stew.

I think by definition a casserole is a meal cooked in a dish with a fitted lid, whether the process was slow or fast, although usually casseroles do cook slowly. Stewing is on the other hand more obviously a slow method of cooking and is traditionally done on a hob.

It does not seem to be a big deal which word you use, but both meals are fantastic options for an easy, convenient and warming meal. They are perfect for using up all the leftover vegetables you have lying around and they allow you to be adventurous with the flavours you include.
