Ingredients

• 2 pounds Yukon Gold potatoes, thinly sliced
• 1½ cups shredded Gruyère cheese
• 1 cup heavy cream
• 2 tablespoons butter
• Salt and black pepper, to taste

How to Make Gruyère Potato Squares

1. Prepare the Potatoes

Preheat your oven to 375°F (190°C). Lightly butter a square or rectangular baking dish. Slice the potatoes very thinly and evenly so they cook at the same rate.

2. Build the Layers

Arrange a layer of potatoes in the bottom of the prepared baking dish. Season lightly with salt and pepper, then sprinkle with some Gruyère. Continue layering the potatoes and cheese until everything is used.

3. Add the Cream

Pour the heavy cream slowly over the potatoes, allowing it to work down between the layers. Dot the top with the remaining butter.

4. Bake

Cover the dish with foil and bake for about 45 minutes. Remove the foil and continue baking for another 20–25 minutes, or until the potatoes are completely tender and the top is deeply golden and bubbling.

5. Cool and Cut

Allow the potatoes to cool for 15–20 minutes before cutting. This resting time helps the layers firm up, making it easier to cut the casserole into neat squares.

Tips for the Best Potato Squares

• Slice the potatoes as evenly and thinly as possible.
• Yukon Gold potatoes provide a naturally buttery texture, but russet potatoes can also work.
• Don’t add too much salt because Gruyère already has plenty of savory flavor.
• Let the casserole rest before cutting so the squares hold together.
• For especially crisp edges, bake the casserole in a shallow dish.

Easy Variations

Add a pinch of garlic powder or fresh thyme for extra flavor. You can also replace some of the Gruyère with Parmesan for a sharper, more savory crust.

For an appetizer-style presentation, cut the cooled potatoes into small bite-sized squares and serve them with toothpicks.

What to Serve With Gruyère Potato Squares

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

They also make a wonderful addition to a holiday buffet or brunch spread.

How to Store Leftovers

Store leftover potato squares in an airtight container in the refrigerator for 3–4 days. Reheat them in a 375°F oven or air fryer until warmed through and crisp around the edges.

Frequently Asked Questions

Can I make these potato squares ahead of time?
Yes. Bake the casserole, let it cool, cover, and refrigerate. Reheat it in the oven before cutting and serving.

Can I use another cheese?
Yes. Swiss, Emmental, cheddar, or a Gruyère blend can be substituted, although Gruyère gives the dish its distinctive nutty flavor.

Why should I let the potatoes cool before cutting?
The short resting period allows the cheese and cream to set slightly, helping the layers stay together when sliced.
