Salmon Potato Gratin is a delicious and comforting dish that combines tender salmon fillets with layers of thinly sliced potatoes, creamy sauce, and melted cheese. The salmon is seasoned with herbs and baked to perfection, while the potatoes become soft and creamy. The creamy sauce adds richness and flavor to the dish, and the melted cheese on top creates a golden and crispy crust. This gratin is a perfect main course for a special dinner or a cozy family meal.
