Ingredients

• 1 1/2 cups heavy cream
• 2 tablespoons unsalted butter, softened

Optional: salt, black pepper, or a small pinch of nutmeg for extra flavor.

How to Make Gruyere Potato Squares

1. Prepare the baking dish

Preheat your oven to 375°F. Lightly butter an 8-inch square baking dish using some of the softened butter.

2. Slice the potatoes

Peel the potatoes and slice them very thinly, about 1/8 inch thick. Keeping the slices uniform helps them cook evenly and makes the finished layers easier to cut.

3. Build the layers

Arrange about one-third of the sliced potatoes in the baking dish. Sprinkle with one-third of the shredded Gruyere and drizzle with one-third of the heavy cream.

Repeat the potato, cheese, and cream layers two more times. Finish by dotting the surface with the remaining butter.

4. Bake covered

Cover the baking dish tightly with aluminum foil and bake for approximately 40 minutes, or until the potatoes are almost tender.

5. Finish uncovered

Remove the foil and return the dish to the oven. Bake for another 20 to 25 minutes, until the Gruyere is melted and bubbling, the top is golden brown, and a knife slides easily through the center.

6. Let the potatoes rest

Allow the baked potatoes to rest for 15 to 20 minutes before cutting. This important step gives the creamy layers time to settle, helping the squares hold their shape when served.

Tips for the Best Potato Squares

Slice the potatoes evenly: A mandoline slicer can make it easier to create thin, consistent slices. If using one, work carefully and use the safety guard.

Don’t skip the resting time: Cutting the potatoes immediately after baking can cause the layers to fall apart. Resting gives you cleaner, more attractive squares.

Use freshly shredded cheese: Freshly shredded Gruyere melts smoothly and gives the dish a rich, nutty flavor.

Season between layers: The recipe is intentionally simple, but a little salt and black pepper between the layers can enhance the potatoes. A tiny amount of nutmeg also pairs beautifully with the cream and Gruyere.

Watch the final bake: Once uncovered, the potatoes can brown quickly. Keep an eye on them during the final 5 to 10 minutes.

Easy Cheese Substitutions

If Gruyere isn’t available, you can substitute Swiss cheese, or use a combination of Swiss cheese and sharp white cheddar. The flavor will change slightly, but the potatoes will still have a creamy texture and golden cheesy topping.

Make-Ahead Instructions

These cheesy potato squares are convenient when you’re preparing a larger meal. Bake them earlier in the day, allow them to cool slightly, and refrigerate if necessary.

To serve, reheat uncovered in a low oven until heated through and the top is warm and lightly golden. Allow the dish to rest briefly before slicing.

Frequently Asked Questions

Can I use a different type of potato?

Yes. White potatoes work well, but Yukon Gold potatoes are also an excellent option because they have a naturally creamy texture.

Why do my potato squares fall apart?

The most common reason is cutting them too soon. Let the baked potatoes rest for 15 to 20 minutes so the cream and cheese layers can set.

Can I prepare these potatoes ahead of time?

Yes. They can be baked earlier in the day and gently reheated before serving.

Can I freeze Gruyere potato squares?

Freezing is possible, but the creamy texture may change slightly after thawing. For the best texture, prepare and refrigerate them instead.
