1Preheat oven to 350 °F. Grease a 9×13-inch baking dish. Peel and slice potatoes into very thin, uniform 1/8-inch rounds using a mandoline.

2Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1–2 minutes until nutty. Slowly pour in milk and cream, whisking constantly.

3Add garlic, onion flakes, salt, and pepper. Whisk over medium heat for 3–4 minutes until sauce coats the back of a spoon. Stir in 2 cups of cheese until melted.

4Layer half the potatoes in the dish, overlapping slightly. Pour half the cheese sauce over them. Add remaining potatoes, then remaining sauce.

5Sprinkle the remaining 1 cup of cheese over the top. Cover tightly with foil.

6Bake covered 30 minutes, then uncover and bake 30 more minutes until top is golden and a fork slides through the potatoes easily. Rest 10 minutes before serving.

Chef's Tips

A mandoline slicer ensures uniform 1/8-inch slices — uneven thickness leads to some slices undercooked while others turn mushy.

Freshly grated cheese melts far smoother than pre-shredded, which contains anti-caking agents that make sauce grainy.

Assemble the night before through the layering step, refrigerate, and bring to room temperature 30 minutes before baking.

If the top browns before potatoes are tender, tent loosely with foil and continue baking.

Recipe Variations

Ham & Potato Au Gratin: Scatter 1 1/2 cups diced smoked ham between the potato layers for a complete one-dish meal.

Slow Cooker: Layer potatoes and sauce in a greased slow cooker, top with cheese, cook on HIGH for 3 hours.

Lighter Version: Replace heavy cream with low-fat evaporated milk and use reduced-fat sharp cheddar.
