  1. You must let the bread soak in the egg mixture overnight or bake right away, the flavours are still there, just the bread on top will be a bit crunchy.
  2. Butter/grease the dish.
  3. Buttery or milk rich bread work best. Baguette and other drier bread do not work so well.
  4. Don’t skimp on the cheese. When in doubt just add a little more.
  5. Skim milk doesn’t work. Generally, skimmed milk might be okay when cooking as a healthier choice, but in these casseroles, the higher fat content of whole milk or light cream is needed.
