Notes
- Slice roast beef into uniform pieces to ensure even cooking and consistent flavor in every bite.
- Use fresh vegetables for the best crunch and flavor, chopping them finely to distribute evenly throughout the casserole.
- Experiment with different cheese varieties like provolone or Swiss to customize the flavor profile and make the dish your own.
- Allow the casserole to rest briefly after baking to help the layers set and make cutting and serving easier.
