Step 5: Serve and Enjoy

Cool Slightly: Let the casserole cool for a few minutes before serving. This will help it set and make it easier to cut into portions.
Serve: Serve the casserole warm, garnished with a sprinkle of fresh parsley if desired.
Tips for Success
Thin Slices: Ensure the potato slices are thin and uniform in size for even cooking. A mandoline slicer can be very helpful for this step.
Pre-cook Potatoes: Pre-cooking the potatoes helps ensure they are fully cooked in the casserole. If you skip this step, make sure to bake the casserole longer until the potatoes are tender.
Season Well: Don’t skimp on the seasoning. The combination of salt, pepper, and paprika adds depth of flavor to the dish.
Cheese: Feel free to use other types of cheese if you prefer. Cheddar or Gruyère can be great alternatives to mozzarella.
