Instead of using canned soup in casserole recipes, I use frozen white sauce cubes I make from a book called "Make Your Own Groceries" by Daphne Metaxas Hartwig.

Editors Note: Use your favorite white sauce recipe or try this: Put equal parts flour and butter, say 2 Tbsp., in a pan over medium low heat. Mix them together as the butter melts and let brown slightly, then add milk and stir. As it thickens, add more milk to your desired consistency.
