creamy cheesy potatoes Potatoes au gratin

Today’s easy potato dish is a longtime family favorite we call Perfect Potatoes Au Gratin. It features thinly sliced potatoes layered in a rich, creamy cheesy sauce, perfectly seasoned, and topped with even more cheese and fresh chopped chives.

Scalloped potatoes vs au gratin

I never really thought much about the difference between scalloped potatoes and potatoes au gratin — until I started looking into it.

We’ve always made these creamy, cheesy potatoes and honestly weren’t sure which name they fell under. We just knew they were incredibly easy and absolutely delicious.

Now that we’ve learned the real difference: Traditional potatoes au gratin are topped with breadcrumbs or cheese and then browned, while scalloped potatoes have no topping at all — even though the top still gets nicely browned.

We skip the breadcrumbs, but like most cheese lovers, we generously add extra cheese on top and broil it until golden and bubbly. So by definition, our version is kind of a delicious cross between the two.

Call them whatever you like — they’re simply irresistible!

The best cheese for au gratin potatoes:

When it comes to the best cheese for au gratin potatoes, the choices are endless.

Personally, I like to keep it simple and use Monterey Jack. It’s inexpensive, melts beautifully, and shreds easily. Many of my Texas friends prefer Longhorn cheddar — a classic hard yellow cheese that works great too.

However, one of the most popular and truly best options is Gruyère. This hard Swiss cheese has a distinctive, nutty flavor that’s perfect for baking — rich without being overpowering.

No matter which cheese you choose, the most important tip is to grate your own. Pre-shredded packaged cheese just won’t give you the same creamy, gooey results. Trust me — it makes all the difference in these cheesy potatoes!

Potatoes au gratin potatoes recipe:

Ingredients

1 ½ cups heavy cream
1 ½ teaspoons salt
¼ teaspoon black pepper
4 large Russet or Yukon Gold Potatoes
4 Tablespoons butter, cut into 1/2 cubes+butter to grease the baking dish
1 ¼ cup shredded Monterrey Jack Cheese, (or Cheddar or Gruyere)
salt
fresh chives, sliced

🥣 Recipe Tips

Slice the potatoes uniformly — Aim for consistent ¼-inch thick slices using a sharp knife or mandoline. Even slices ensure the potatoes cook at the same rate, giving you tender results without some pieces being underdone or mushy.
Always grate your own cheese — Freshly grated Monterey Jack (or your choice of cheddar or Gruyère) melts much better and creates that creamy, gooey texture. Pre-shredded packaged cheese contains anti-caking agents that can make the sauce grainy, so skip it for the best results.
Let the dish rest before serving — After removing it from the oven, allow the potatoes to cool for about 10 minutes. This helps the creamy sauce thicken slightly and makes the layers hold together better when you scoop them out.

How to make perfect potatoes au gratin:

Preheat your oven to 350°F.
Start by peeling the potatoes, then use a sharp knife or mandoline to slice them about ¼ inch thick.
Butter a 7×11-inch baking dish and layer half of the potato slices in the bottom, overlapping them like fallen dominoes.
For extra flavor and richness, dot each layer with butter. (Real butter just makes everything better — it makes my soul happy, and as the Pioneer Woman says, “It makes my skirt fly up!” I smile every time I hear that.)

Sprinkle ½ cup of the Monterey Jack cheese over the first layer of potatoes.
In a medium mixing bowl, whisk together the cream, salt, and pepper until well blended. Pour half of the cream mixture evenly over the potatoes.
Repeat the layers: add the remaining potato slices, dot with more butter, sprinkle with another ½ cup of cheese, and pour the rest of the cream mixture over the top.
Cover the dish with foil and bake in the preheated 350°F oven for 30 minutes.

Remove the foil and bake for an additional 15–25 minutes, until the potatoes are tender and the top is starting to turn golden brown.
Sprinkle with the remaining ¼ cup of cheese and bake for another 5 minutes, just until the cheese is melted and bubbly.
Remove from the oven and let the dish cool for about 10 minutes. Sprinkle with fresh chopped chives right before serving.

These Perfect Potatoes Au Gratin come out incredibly creamy, cheesy, and full of flavor with that beautiful golden top. They’re the kind of comforting side dish that turns any meal into something special — perfect for busy weeknights or holiday gatherings.
