Preparation
Chef’s notes
Gruyere cheese brings sophisticated flavor to this super-simple potato recipe. If you’ve never tried Gruyere before, you’re in for a treat.
Tossing thinly sliced potatoes with the cream sauce before adding them to the casserole dish allows each potato to be coated with sauce, for the tastiest gratin potatoes.
Cheesy potatoes au gratin are great to make ahead for a delicious Thanksgiving or Christmas side dish.
