3. Layer half of the potato matchsticks in the prepared dish, followed by half of the sliced onion.
4. Distribute the anchovy fillets evenly over the onion layer, pouring a little of the anchovy brine over them.
5. Cover with the remaining potato matchsticks and the rest of the onion.
6. Pour the heavy cream evenly over the casserole, ensuring all ingredients are mostly submerged.
7. Dot with small pieces of butter and sprinkle with breadcrumbs and freshly ground black pepper.

9. Serve immediately as a comforting side dish or a light main course, traditionally enjoyed during holidays.
