These potatoes are a creamy, cheesy version of scalloped potatoes. I make them every Christmas for sure and many times in between.

Working in a compact kitchen means running two burner operations simultaneously without cluttering the counters. Simmering the sliced Idaho potatoes in salted water while building the dairy-based sauce on the adjacent burner requires deliberate management of space. Slicing those tubers between one-eighth and one-quarter of an inch thick ensures they withstand boiling without turning to mush before reaching fork tenderness. Making the cheese sauce demands pulling the saucepan off the burner entirely before whisking in the flour, preventing scorching and stubborn lumps before the milk goes in gradually. Pouring cold dairy into hot fat too fast breaks the emulsion, so constant whisking over medium-low heat is non-negotiable for achieving a velvety texture. Assembling the casserole in layers alternates starchy vegetable slices with rich sauce until the baking dish is full, finishing at a 375 degree oven temperature for thirty minutes. Watch for bubbling edges and a light brown surface finish to signal complete heat penetration through the entire depth of the dish.
