- Repeat with another layer of potatoes, a small pinch of salt, freshly ground pepper and ⅓ egg mixture. Top again with ½ cup Gruyère and 1 tablespoon of prosciutto.
- Top with the last layer of potatoes, a small pinch of salt and freshly ground pepper, and the remaining egg mixture. Top again with 1/2 cup Gruyère and 1 tablespoon of prosciutto cubetti.Cover with a buttered foil sheet and bake until potatoes are tender, about 40 minutes.
