Baked Fish and Potato Casserole

Flaky white fish fillet layered over thinly sliced potatoes in a shallow dish, baked under a cream and Gruyere topping until golden and bubbling. Leeks and garlic add sweetness, a touch of Dijon and thyme sharpen the sauce, and the potatoes turn tender beneath the browned crust.
