Chicken, Mushroom and Potato Gratin

This chicken and mushroom potato gratin suits a weeknight dinner that should feel generous without much effort. Everything is layered in a single baking dish, and the oven does the rest. The ingredients are everyday staples: potatoes, chicken breast, mushrooms, onion, sour cream, and a good melting cheese.

The texture depends on slicing everything thin. Potato rounds and slim slices of chicken cook through evenly, while the sour cream spread over each layer slowly seeps down through the dish and mingles with the juices released by the mushrooms and onion. Because the chicken sits at the bottom, beneath the vegetables, it gently braises in that sauce and in its own juices instead of drying out. Freshly grated nutmeg adds a warm, faintly sweet note that rounds out the creaminess of the sour cream.

Covering the dish with foil for the first stretch traps steam, so the potatoes soften all the way through and the surface stays moist. Once the foil comes off, the cheese melts and browns into a golden crust.

After a short rest, the gratin firms up enough to hold a clean slice with every layer intact. Fresh herbs on top and a crisp, lightly dressed green salad on the side balance the richness.
