I am the proud owner of a new slow cooker - so far have made a beef stew and a bolognaise in it, both of which came out really well but I cooked them both while I was at home, and on the quickest setting. I am at work tomorrow and planning on doing a chicken casserole - I will be leaving home at 8.30 and will be back no later than 5.30...is this too long to leave it on the lowest setting or is this going to be ok? It seems ages - I can't get my head round leaving the dinner on and going out all day!?!?
