Ingredients You’ll Need
Each ingredient has an important job in creating the perfect creamy Potato Gratin Savoyard.
1. 2 1/2 pounds Yukon Gold potatoes, peeled
Yukon Gold potatoes are ideal for this recipe because they have a naturally buttery flavor and creamy texture. They become wonderfully tender during baking while holding their shape well enough to create beautiful layers. Slice them approximately 1/8 inch thick for even cooking.
2. 2 cups heavy cream
Heavy cream is the secret to the gratin’s luxurious texture. It works its way between the potato slices as the dish bakes, creating a rich, silky consistency. It also helps keep the potatoes moist and tender throughout the cooking process.
3. 2 cups shredded Gruyere cheese
Gruyere gives this traditional-inspired potato casserole its signature nutty, slightly sweet, savory flavor. It melts beautifully between the layers and creates a gorgeous golden topping. Freshly shredded cheese is especially good because it melts smoothly.
4. 1 1/2 teaspoons kosher salt
Salt brings out the natural sweetness of the potatoes and balances the richness of the cream and cheese. Distributing it between the layers ensures that every bite is properly seasoned.
How to Make Oven-Baked Potato Gratin Savoyard
This easy baked potato gratin recipe comes together with a few simple steps.
Step 1: Prepare the oven and baking dish
Preheat your oven to 375°F (190°C). Lightly butter or grease an oval or similar 2 1/2- to 3-quart baking dish.
Peel the Yukon Gold potatoes and slice them into thin, even rounds, approximately 1/8 inch thick. A mandoline makes this job easier, but a sharp knife works perfectly too.
Step 2: Start layering the potatoes
Arrange a thin, even layer of sliced potatoes across the bottom of your prepared baking dish.
Sprinkle lightly with some kosher salt and a small handful of shredded Gruyere cheese.
Continue layering the potatoes, salt, and cheese until all the ingredients have been used. Finish with a generous layer of Gruyere on top for that beautiful golden finish.
Step 3: Add the heavy cream
Slowly pour the heavy cream evenly over the layered potatoes.
Use the back of a spoon to gently press the potatoes down, helping the cream settle between the slices. This step helps create that wonderfully tender, creamy texture.
Step 4: Bake until tender and golden
Cover the baking dish loosely with aluminum foil and place it in the preheated oven.
Bake for 45 minutes.
Remove the foil and continue baking for another 25–35 minutes, or until the potatoes are completely tender and the top is deeply golden and bubbling around the edges.
To check for doneness, insert a thin knife into the center. It should slide through the potato layers easily.
Step 5: Rest before serving
Remove the gratin from the oven and allow it to rest for 10–15 minutes before serving.
This resting time allows the cream to thicken slightly and helps the layers settle, making it easier to spoon out beautiful portions.
Serve warm and enjoy every creamy, cheesy bite!
Pro Tips for the Best Potato Gratin Savoyard
Slice the potatoes evenly. Consistent 1/8-inch slices are essential for even cooking. Thick slices may remain firm while thinner ones become overly soft.
Choose the right potatoes. Yukon Gold potatoes provide an excellent balance of creamy texture and structure. Russet potatoes can also work, but they tend to create a softer, less defined layer.
Use freshly shredded Gruyere. Freshly grated cheese generally melts more evenly than many packaged pre-shredded varieties.
Don’t rush the baking process. The covered baking time helps the potatoes become tender, while uncovering the dish allows the cheese to brown and develop its delicious crust.
Let it rest before serving. Those extra 10–15 minutes make a noticeable difference in the consistency of the gratin.
Watch the top carefully. If the cheese becomes golden before the potatoes are tender, loosely cover the dish again and continue baking until the center is cooked through.
Easy Variations to Try
Although the original four-ingredient version is wonderfully satisfying, you can make a few small adjustments depending on your preferences.
– Add garlic: Rub a cut garlic clove around the inside of the buttered baking dish before adding the potatoes for a subtle aromatic flavor.
– Try another cheese: Swiss cheese or Comte can replace Gruyere while keeping a similar nutty flavor.
– Add black pepper: A little freshly ground black pepper between the layers adds gentle warmth.
– Use Russet potatoes: For a softer, more delicate texture, substitute Russets for Yukon Golds.
These additions are optional. The original four-ingredient combination is delicious just as written.
What to Serve with Potato Gratin Savoyard
This old-fashioned cheesy potato side dish is rich enough to feel special but versatile enough to accompany many main courses.
Here are some delicious serving ideas:
– Thanksgiving turkey: Serve alongside roasted turkey, traditional stuffing, cranberry sauce, and green beans.
– Holiday ham: The salty, savory flavor of baked ham pairs beautifully with the creamy Gruyere potatoes.
– Roast beef: A slice of tender roast beef makes this gratin an excellent Sunday dinner companion.
– Roasted chicken: Keep things simple with juicy oven-roasted chicken and steamed vegetables.
– Fresh green salad: A crisp salad with a tangy vinaigrette balances the richness of the cream and cheese.
– Steamed broccoli or green beans: Fresh vegetables add color and freshness to the plate.
For a complete holiday meal, pair it with roasted meat, seasonal vegetables, dinner rolls, and your favorite family dessert.
Make-Ahead and Storage Tips
Can you prepare potato gratin ahead of time?
Yes! You can assemble the layers several hours ahead, cover the baking dish, and refrigerate it before baking. Allow it to sit at room temperature for approximately 20–30 minutes before placing it in the oven. Make sure the center becomes fully tender during baking.
How do you store leftovers?
Allow leftover gratin to cool, then transfer it to an airtight container or cover the baking dish tightly. Refrigerate for up to 3–4 days.
How do you reheat potato gratin?
For the best results, reheat individual portions in the microwave or warm a larger portion in a 325°F oven, covered with foil, until heated through. Remove the foil near the end if you want to refresh the golden top.
Can you freeze potato gratin?
Freezing is possible, but cream-based potato dishes may change texture after thawing. For the creamiest results, enjoy this recipe freshly baked or refrigerated.
