I did this in the slow cooker but, unfortunately, it was one of my late nights and I can only imagine it cooked too long. The cheese was in big globs in the soup, kind of unappetizing! I tried adding the flour and soup as recommended to get the cheese to melt into the soup but it didn't work. It tasted good! It makes a pretty small amount so, if you are planning on feeding a family, you'll need to make a double batch. Sorry, not planning on repeating.
