Creamy Scalloped Potatoes (Potato Gratin Style)

There’s something magical about a pan of scalloped potatoes coming out of the oven. The bubbling cream, the golden top, the soft and melt in your mouth layers… it’s everything comforting, cozy, warm, and nostalgic about food in one dish. This recipe is rich and creamy with perfectly tender potatoes and a golden cheesy crust. It’s a must have for holidays like Thanksgiving, Easter, and Christmas… but honestly^, I’ll make this any time I just want something comforting.

Thinly sliced potatoes are mixed with a rich cream sauce flavored with onion, garlic, herbs, butter, and seasoning. The sauce is poured over the potatoes to coat every slice, then everything is baked slowly in the oven until the inside becomes silky soft and the top turns beautifully caramelized. This is the definition of simple ingredients turning into something honestly irresistible.


Scalloped Potatoes vs Au Gratin

Some people get really technical with this distinction. Traditionally: Scalloped potatoes are baked in cream or milk, usually with onion and seasoning, but no cheese. Potatoes au gratin include cheese, either inside, on top, or both. Now… most modern scalloped potatoes recipes absolutely use cheese. So yes, technically you could call this a potato gratin or potatoes au gratin, but scalloped potatoes is the name most people know and use when they want this dish. That is why I use it here, while still giving it that cheesy gratin style richness.


The Best Potatoes to Use

For this dish, you want a potato that gets tender, creamy, and breaks down slightly as it cooks. Look for: Starchy potatoes like russet or king edward
Or
Yukon gold or yellow potatoes for a creamier texture and buttery flavor Waxy potatoes like red potatoes hold their shape too much and will not become as soft and velvety.


How to Make It Step by Step

(Full recipe in recipe card below)

Slice the potatoes thinly: Use a mandoline to slice the potatoes very thin so they cook evenly and become soft and silky.
Sauté onions and garlic: Cook sliced onions and garlic in a pan until they soften and start to get a little golden. This builds the base flavor of the sauce.
Pour in the cream: Slowly pour in the heavy cream or coconut milk and stir until smooth. Then add your herbs, salt, pepper, and seasoning.
Mix with the potatoes: Pour the finished sauce over the sliced potatoes and gently mix. Every slice should be coated so they bake evenly and stay moist.
Arrange and bake: Arrange the potatoes in a baking dish, add any remaining sauce over the top, cover with foil and bake. Remove the foil, add cheese, and bake until golden and bubbling.

Frequently Asked Questions

Can I use a knife instead of a mandoline

Yes, but the slices must be very thin and even. A mandoline just makes that easier and ensures the potatoes cook through properly.

How do I know when it is done

he potatoes should be completely tender and soft all the way through and the top should be golden and bubbling. You should be able to slide a knife through with zero resistance.

Can I add other ingredients like mushrooms or leeks

Absolutely. Mushrooms, leeks, or even vegan bacon bits work well. Just sauté them with the onion and garlic before adding the cream.

Can You Make It Ahead

Yes, absolutely, and here is a little secret. The leftovers might actually be even better.

You can:
Assemble everything fully
Bake covered
Let it cool
Refrigerate
Then reheat the next day Or you can bake it halfway, chill it, and finish baking right before serving. The potatoes absorb more flavor overnight and the texture becomes incredibly rich.

What to Serve With Scalloped Potatoes

Scalloped potatoes are a dream side dish. They pair beautifully with:
Holiday main dishes
