Potatoes Dauphinoise are potatoes, cream, cheese, and a French lineage. They're like scalloped potatoes and potatoes au gratin but are even more fancy but without being fussy. We really don't think comfort food gets any more comfort-y than this.

Equipment
Mandoline(optional) but best for thin, even slices
Ingredients
1garlic clove, smashed with the side of a knife blade
butter, for greasing the dish
3cupsheavy cream, (or 2 cups cream and 1 cup whole milk)
5sprigsfresh thyme
freshly ground nutmeg
salt, plus more to taste
3poundsYukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick)
freshly ground black pepper
1 1/2cupsgrated Gruyère cheese, or Jarlsberg, Comté, Emmental, or Fontina
Rub the crushed 1 garlic clove all over the inside of a 2 1/2-quart casserole or a 9-by-13-inch baking dish, then butter it thoroughly.
Pour the 3 cups heavy cream (or cream and milk) into a saucepan. Add the garlic clove, 5 sprigs fresh thyme, freshly ground nutmeg, and a large pinch of salt.
Warm the cream over low heat and gently simmer for 10 minutes. Remove the pan from the heat and fish out the garlic and thyme.
Lay a single layer of sliced 3 pounds Yukon Gold potatoes in the baking dish, overlapping the slices like playing cards. Sprinkle with a small pinch of salt and freshly ground black pepper.
Continue layering and seasoning the potatoes until all of the potatoes are used.
Pour the seasoned cream over the potatoes and sprinkle the top with the 1 1/2 cups grated Gruyère cheese.
Cover the dish with aluminum foil and bake for 1 1/2 hours.
Remove the foil and continue baking until the top is bubbling and spotted with brown, and a fork easily pierces the potatoes, 25 to 35 minutes, depending on the size and depth of your dish.
Let the dish sit for 15 minutes before serving.
Notes
Make in advance—Assemble and bake up to 1 day before serving. When ready to serve, reheat in a 350°F oven until warmed through.
Storage—Leftovers will keep in a covered container in the fridge for up to 4 days.
Avoid oven spills—If your baking pan is very full, place it on a foil-lined baking sheet to catch any drips that bubble over.
Traditional recipe—if you want to go totally old-school, omit the cheese. It'll still be frickin' delicious.
