Ingredients

• 2 pounds Yukon Gold potatoes
• 1½ cups shredded Gruyere cheese
• ½ cup heavy cream
• 3 tablespoons butter, melted

These are the 4 main ingredients in the recipe. Salt and pepper may be added to taste without changing the main ingredient count.

How to Make Gruyere Potato Squares

1. Prepare the Potatoes

Preheat your oven to 400°F (200°C).

Lightly grease an 8×8-inch or 9×9-inch baking dish.

Peel the potatoes if desired, then slice them very thinly and evenly. A mandoline makes this step especially easy.

2. Build the Layers

Arrange a layer of sliced potatoes across the bottom of the prepared baking dish.

Drizzle with a little melted butter and heavy cream, then sprinkle with some of the Gruyere cheese.

Continue layering the potatoes, butter, cream, and cheese until everything is used, finishing with a generous layer of Gruyere on top.

3. Bake Covered

Cover the baking dish tightly with aluminum foil.

Bake for about 35–40 minutes, or until the potatoes are becoming tender when pierced with a knife.

4. Bake Until Golden

Remove the foil and continue baking for another 20–25 minutes, until the potatoes are completely tender and the cheese is deeply golden and bubbling.

For extra-crispy edges, you can place the dish under the broiler for 1–2 minutes at the end. Watch closely so the cheese doesn’t burn.

5. Cool and Cut

Let the potato bake rest for 10–15 minutes before cutting.

For clean squares, allow it to cool slightly longer so the layers have time to set. Cut into squares and serve warm.

Tips for the Best Gruyere Potato Squares

Slice the potatoes as evenly as possible. Uniform slices cook at the same rate and create neater layers.

Yukon Gold potatoes work particularly well because they have a naturally creamy texture while still holding their shape.

Don’t skip the resting time. Cutting the potatoes immediately after removing them from the oven can cause the layers to fall apart.

For the crispiest top, make sure the final layer of cheese is evenly distributed across the surface.

Easy Variations

• Extra cheesy: Add a little Parmesan along with the Gruyere.
• Herby: Add fresh thyme or rosemary.
• Garlic: Rub the baking dish with a cut garlic clove before adding the potatoes.
• Crispier: Use a slightly larger baking dish for thinner layers and more browned edges.
• Mini appetizers: Cut the finished potatoes into small squares for parties.

What to Serve With Gruyere Potato Squares

These cheesy potato squares pair beautifully with roasted chicken, pork roast, steak, baked ham, grilled vegetables, or a simple green salad.

They’re also an excellent addition to holiday and Sunday dinner tables.

How to Store Leftovers

Store leftover potato squares in an airtight container in the refrigerator for up to 3–4 days.

For the crispiest texture, reheat them in a 400°F (200°C) oven or air fryer until hot and the edges have crisped again.

Avoid reheating them for too long in the microwave if you want to preserve their crispy texture.

Frequently Asked Questions

Can I use another type of potato?

Yes. Russet potatoes can be used, although Yukon Gold potatoes provide a creamier texture. Avoid potatoes that are unusually waxy because they may not soften as evenly.

Can I use another cheese?

Absolutely. Fontina, Swiss, cheddar, or a combination of cheeses can work well, although Gruyere gives the dish its distinctive nutty flavor.

Can I make these potato squares ahead of time?

Yes. Bake the potato dish, let it cool, cover, and refrigerate. Reheat it in the oven until hot and crisp before cutting and serving.

How do I get crispier edges?

Use thin, even potato slices and avoid overcrowding the dish. Finishing uncovered at a higher oven temperature or briefly under the broiler will also help brown the edges.
