Why should you want to do that? A slow cooker is what it says - a slow cooker. Perfect if you want to go out all day and come home to a lovely cooked meal.
Thanks everyone for your answers. Dont think I will risk it then. Just wanted to know cus am making stew and dumplings and really like the dumplings well done and crispy which the slow cooker fails to do. Oh well will just have to transfer it to an oven proof dish. Cheers again
