Why You’ll Love This Recipe
There is something especially comforting about homemade scalloped potatoes fresh from the oven. The thin potato slices become wonderfully tender while the milk, butter, and flour create a rich, creamy sauce as everything bakes together.
This recipe is also refreshingly straightforward. There is no need to prepare a separate cheese sauce or use hard-to-find ingredients. Simply layer everything in the baking dish, add warm milk, and let the oven do most of the work.
These creamy scalloped potatoes are mild enough for the whole family and versatile enough to pair with roasted chicken, grilled beef, baked fish, vegetables, or a fresh salad.
Ingredients
- 3 pounds russet potatoes, thinly sliced
- 1/2 onion, thinly sliced
- 9 tablespoons all-purpose flour, divided
- 6 tablespoons butter, cubed and divided
- Salt, to taste
- Ground black pepper, to taste
- 3 cups whole milk, or as needed
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Peel the potatoes if desired, then cut them into thin, even slices. Thinly slice the onion as well.
- Arrange one-third of the sliced potatoes evenly across the bottom of the prepared baking dish.
- Scatter one-third of the sliced onion over the potatoes. Sprinkle 3 tablespoons of flour evenly over the layer, then dot the surface with 2 tablespoons of cubed butter. Season lightly with salt and black pepper.
- Repeat the layering process two more times using the remaining potatoes, onions, flour, butter, salt, and pepper.
- Warm the whole milk in a saucepan over medium-low heat. Do not let it boil.
- Carefully pour the warm milk over the layered potatoes until the liquid reaches approximately the level of the top potato layer.
- Place the baking dish on a rimmed baking sheet to catch any sauce that may bubble over during baking.
- Bake the Scalloped Potatoes for 45 to 60 minutes, or until the potatoes are fork-tender, the sauce is bubbling, and the top develops an appetizing golden-brown finish.
- Remove the baking dish from the oven and allow it to rest for about 10 minutes before serving. This short resting period helps the creamy sauce settle and thicken around the potatoes.
Tips & Tricks
Slice the potatoes as evenly as possible so they cook at the same rate. A mandoline slicer can make this quick and easy, but a sharp kitchen knife works well too.
Avoid cutting the potatoes too thick. Thin slices cook more evenly and help create the soft, layered texture expected from an easy scalloped potatoes recipe.
Warm the milk before adding it to the baking dish. Starting with warm rather than refrigerator-cold milk helps the dish heat more evenly.
Place your baking dish on a rimmed sheet pan before putting it into the oven. The creamy sauce can bubble vigorously as it cooks, and the sheet pan makes cleanup much easier.
If the surface begins browning before the potatoes are fully tender, loosely cover the dish with foil and continue baking until the center is cooked.
For an extra-rich variation, replace part of the whole milk with heavy cream. For a slightly lighter version, use 2% milk, keeping in mind that the finished sauce may be less rich.

Notes
For the creamiest texture, russet potatoes are an excellent choice because their natural starch helps give the sauce body as the dish cooks.
Yukon Gold potatoes can also be used for a slightly buttery flavor and firmer texture.
These oven baked potatoes are especially delicious alongside roasted chicken, grilled or roasted beef, baked fish, steamed vegetables, green beans, or a crisp garden salad.
For a richer variation, sprinkle halal-friendly shredded cheddar between the layers. The traditional version provided here does not require cheese.
Let the finished casserole rest briefly before serving rather than cutting into it immediately. The sauce will settle and cling more effectively to the potato layers.

FAQ
What are Scalloped Potatoes?
They are a classic baked potato side dish traditionally prepared by layering thin potato slices with a creamy milk-based sauce. The potatoes slowly become tender while baking, and the sauce thickens around the layers.
What are the best potatoes for homemade scalloped potatoes?
Russet potatoes work particularly well because their high starch content contributes to a creamy finished sauce. Yukon Gold potatoes are another good option if you prefer potatoes that hold their shape a little more firmly.
How thin should I slice the potatoes?
Aim for consistently thin slices, roughly 1/8 inch thick. Uniform slices are more important than achieving an absolutely exact measurement because they help all the potatoes become tender at approximately the same time.
Why are my scalloped potatoes still hard?
The potatoes may simply need additional baking time, particularly if they were cut thicker than recommended. Cover the dish loosely with foil if the surface is already browned, then continue baking until a knife or fork easily passes through the center slices.
Can I make creamy scalloped potatoes ahead of time?
Yes. You can bake the dish ahead, let it cool, cover it, and refrigerate it. Reheat it covered in the oven until the center is thoroughly heated, removing the foil near the end if you want to refresh the browned top.
Can I add cheese to this easy scalloped potatoes recipe?
Yes. Although cheese isn’t required for this version, shredded halal-friendly cheddar, mozzarella, or a combination of cheeses can be layered with the potatoes for a richer variation.
Storage
Allow leftovers to cool before transferring them to an airtight container or covering the baking dish tightly. Store in the refrigerator for up to 3–4 days.
For longer storage, divide cooled potatoes into freezer-safe portions and freeze for up to 2 months. Keep in mind that freezing and thawing can slightly change the texture of potatoes and dairy-based sauces.
Thaw frozen portions overnight in the refrigerator before reheating whenever possible.
For best results, reheat leftovers in a covered oven-safe dish at 350°F (175°C) until thoroughly hot. Individual portions can also be reheated in the microwave. Adding a small splash of milk before reheating can help restore some of the creamy consistency.
