Cheesy scalloped potatoes are a classic, crowd-pleasing side dish made with thinly sliced potatoes layered with Gruyère and Parmesan, then baked until creamy, bubbling, and golden on top. Often called potatoes au gratin, this rich potato casserole is perfect for Easter, Christmas, Thanksgiving, or any special-occasion dinner.

This cheesy scalloped potatoes recipe is all about real ingredients and reliable results: fresh potatoes, good cheese, milk or half-and-half, and fragrant herbs. I slice the potatoes ⅛-inch thick, then gently simmer them in the dairy until just tender before layering and baking. That extra step makes the recipe practically foolproof-no crunchy centers, just creamy, tender potatoes with beautifully melted cheese in every layer.

Chef's tip on buying potatoes:
Potatoes labeled "yellow" or "gold" are both yellow-fleshed varieties and work especially well for scalloped potatoes because they have a creamy texture while still holding their shape. Choose larger potatoes when possible-they're easier to peel and slice evenly on a mandoline or a hand slicer. Skip bagged potatoes if you can and select them individually, looking for smooth skins with no sprouts, soft spots, or green patches.
Substitutions and Variations
- Cheese options - If you can't find Gruyère, use another good-melting cheese such as Comté, Fontina, or a mild white cheddar.
- Herb options - Dried thyme can stand in for fresh; use about one-third to one-half as much. Fresh marjoram also works well, or use a small amount of fresh rosemary since its flavor is stronger. Dried Italian seasoning is another easy option.

Chef's Tip - Why I Simmer the Potatoes First
Most scalloped potato recipes layer raw slices with cream and cheese, but the center can stay underdone and the timing is less predictable. I prefer to slice the potatoes ⅛-inch thick and gently simmer them in the milk or half-and-half first, just until tender, then layer and bake. I used this method for catered dinners for years because it consistently produced creamier, evenly tender potatoes with reliable results.
How to Make Cheesy Scalloped Potatoes
Tools note - To slice the potatoes perfectly evenly, use either a food processor with an ⅛"-inch sliced blade or a mandoline.

- Peel potatoes and slice ⅛" thick.

- Simmer potatoes in milk with herbs just until tender when pierced.

- Begin layering potato slices into a buttered 9x9 or two quart casserole dish alternating with the grated Gruyere and Parmesan cheeses.

- Finish layering and end with the rest of the cheese and parmesan. Bake scalloped potatoes until golden brown on top and the potatoes are set and a bit firm. They will set more upon cooling for a few minutes which makes slicing easier.
Chef's tool tip: If you don't have a food processor, a classic tool called a mandoline is a terrific kitchen tool for slicing at an economical price. Slice potatoes, apples, pears, beets, carrots and other fruits and vegetables uniformly thin when needed.
Make-Ahead & Re-Heat
Assemble and bake the scalloped potatoes until the potatoes are just tender and the top is lightly golden, then cool, cover, and refrigerate for up to 1 day.
Before serving, let the dish sit at room temperature while the oven heats, up to about 1 hour. Reheat covered at 350°F until hot, then uncover for the last few minutes to re-crisp and brown the top.
Serving Suggestions
Cheesy scalloped potatoes pair beautifully with roast beef tenderloin, roast chicken, pork roast, Thanksgiving turkey, or Easter ham, making them a natural choice for holiday and special-occasion dinners.
Because scalloped potatoes are rich and filling, keep the rest of the meal simple. Serve them with a green vegetable such as these blanched green beans and add a crisp side salad for freshness and balance.

Storage
Leftover cheesy scalloped potatoes keep in the refrigerator in an airtight container for up to 4 days.
To reheat, warm portions in the microwave until hot, or cover the dish with foil and bake in a preheated 350°F oven until heated through. Timing will depend on how cold they are from the refrigerator, but they should reach 165°F internally when checked with a digital thermometer.
Recipe FAQs
Yes. Bake them a day ahead, cool completely, cover well, and refrigerate. Remove the dish from the refrigerator about 1 hour before reheating, then warm in a 350°F oven until heated through and the center reaches 165°F.
Absolutely. Add roasted garlic, crisp crumbled bacon, or thinly sliced onions and garlic that have been sautéed before layering. These are easy ways to change the flavor without altering the basic method.
Gold or yellow potatoes work especially well because they have a creamy texture while still holding their shape after slicing and baking. Russets are starchier and tend to break down more, so I prefer to save them for baked or mashed potatoes.

Instructions
Peel and Slice the Potatoes
- Pre-heat the oven to 350 degrees. Peel the potatoes and slice on a mandolin or hand-held slicer adjusted to ⅛″ (3-4 cm) thickness.
Simmer Potatoes
- Place the potatoes and milk in a deep sauté pan and bring to a simmer over medium heat. Add the thyme, salt and pepper. Cover and turn heat to low. Watch carefully and don't let the milk boil over. It's messy to clean up and happens in the blink of an eye. Simmer over low for about 7 minutes or until potatoes are tender when pierced with the tip of a sharp paring knife. Remove potatoes from the heat and allow to cool a bit.
Assemble the Casserole
- Layer half of the potatoes in a lightly buttered or sprayed 9x9 square casserole or oval baking dish. Sprinkle with the nutmeg. Add ⅔ of the grated cheese. Layer on the rest of the potatoes and top with remaining ⅓ of the cheese and Parmesan.
Bake the Potatoes
- Bake casserole uncovered for 50-60 minutes, until the top is golden brown. Remove from the oven and allow to cool for a few minutes. Slice and serve.
