Ingredients You’ll Need
These ingredients are deceptively simple but each one plays an essential role in making the Potato Gratin Recipe truly spectacular. From the creamy dairy that ensures silky smoothness to the aromatic spices that uplift every layer, every component counts.
- 2 pounds Yukon Gold or Russet potatoes: The backbone of the dish, thinly sliced for tender, melt-in-your-mouth texture.
- 2 cups heavy cream: Provides the rich, velvety base that makes each bite so decadent.
- 1 cup whole milk: Lightens the cream slightly to balance richness with softness.
- 2 cloves garlic, minced: Adds a warm, savory depth that beautifully complements the cheese.
- 1 teaspoon salt: Enhances all flavors, ensuring the potatoes don’t taste bland.
- ½ teaspoon black pepper: Offers a subtle hint of spice and complexity.
- ¼ teaspoon ground nutmeg: A classic touch for potato gratins, lifting the creamy mixture with a mild, nutty aroma.
- 1½ cups shredded Gruyère cheese: Melts perfectly, providing the dish’s signature nutty, slightly sweet flavor.
- ½ cup grated Parmesan cheese: Adds a sharp, salty finish and a beautifully browned crust.
- 1 tablespoon unsalted butter (for greasing): Prevents sticking and lends a subtle richness to the baking dish.
How to Make Potato Gratin Recipe
Step 1: Prepare and Preheat
Start by preheating your oven to 375°F (190°C). This ensures your gratin bakes evenly and the cheese melts into that irresistible golden crust. Grease a 9×13-inch baking dish with the unsalted butter to keep the potatoes from sticking and add a delicate buttery aroma as the dish cooks.
Step 2: Make the Cream Mixture
Combine the heavy cream, whole milk, minced garlic, salt, pepper, and ground nutmeg in a saucepan. Heat it gently over medium heat until warm—just shy of boiling—to meld the flavors without curdling. This fragrant cream mixture will soak into the potatoes, infusing every slice with silky richness and subtle spice.
Step 3: Layer the Potatoes
Arrange half of the thinly sliced potatoes in an even layer in your prepared dish, allowing them to overlap slightly so no gaps remain. This layering technique ensures every bite has that perfect balance of potato and creamy sauce.
Step 4: Add Cream and Cheese
Pour half of your warm cream mixture over the potato layer, letting it seep into all the nooks and crannies. Then sprinkle half of the Gruyère and Parmesan cheeses evenly on top, building up that irresistible cheese pull we all love.
Step 5: Repeat Layers
Now repeat the process with the remaining potatoes, cream mixture, and cheeses. The second layer adds even more lusciousness and flavor, promising a dish that’s rich and satisfying through and through.
Step 6: Bake Covered
Cover the dish tightly with foil and bake for 45 minutes. This initial covered baking gently cooks the potatoes, allowing them to soften while the flavors meld perfectly without over-browning.
Step 7: Uncover and Finish Baking
Remove the foil and continue to bake uncovered for an additional 25 to 30 minutes, or until the top develops a beautiful golden brown crust and the potatoes are tender through when pierced with a knife. This final uncovered baking step creates that signature crispy, cheesy topping everyone adores.
Step 8: Rest Before Serving
Once out of the oven, let the gratin sit for about 10 minutes. This resting time allows the creamy layers to set slightly, making it easier to serve and giving the flavors a chance to harmonize fully.
How to Serve Potato Gratin Recipe
Garnishes
To elevate the already rich Potato Gratin Recipe, consider sprinkling finely chopped fresh herbs like thyme or chives on top just before serving. A light dusting of freshly ground black pepper or a drizzle of truffle oil can add an extra flare that makes the dish feel special and ultra-decadent.
Side Dishes
This gratin pairs beautifully with roasted meats such as chicken, pork, or beef, balancing hearty proteins with its creamy texture. For a vegetarian meal, serve alongside sautéed greens like spinach or kale for a vibrant, healthy contrast. A crisp green salad with a tangy vinaigrette is also perfect to cut through the richness.
Creative Ways to Present
For holiday dinners or when entertaining guests, try serving this Potato Gratin Recipe in individual ramekins for an elegant touch. Alternatively, bake it in a cast iron skillet to get extra crispy edges, then bring the skillet straight to the table for a rustic, inviting feel.
Make Ahead and Storage
Storing Leftovers
Leftover Potato Gratin Recipe is a blessing the next day. Cool it completely, cover it tightly with plastic wrap or foil, and store in the refrigerator for up to 3 days. Reheat gently to maintain the creamy texture and avoid drying out the potatoes.
Freezing
You can freeze this dish if you want to prepare in advance. After baking and cooling, cover it securely with foil and plastic wrap to prevent freezer burn. Freeze for up to 2 months. To enjoy, thaw overnight in the fridge before reheating for best texture.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 20 minutes or until warmed through. Cover loosely with foil to keep moisture in, uncover near the end to refresh the crisp cheese top. Avoid microwaving as it can make the gratin watery and less appealing.
FAQs
Can I use different types of potatoes?
Yes! Yukon Gold and Russet potatoes are ideal for their balance of firmness and creaminess. Yukon Gold yields a buttery texture, while Russets absorb more cream. Avoid waxy potatoes like red or new potatoes as they don’t soften as well.
Is there a substitute for Gruyère cheese?
Absolutely! If you can’t find Gruyère, sharp white cheddar or Swiss cheese are excellent alternatives that melt well and maintain the nutty, rich flavor profile essential for a great gratin.
Can I make this dish dairy-free?
This traditional Potato Gratin Recipe relies heavily on cream and cheese, making dairy-free versions challenging. However, you can experiment with plant-based cream substitutes and vegan cheese, although the texture and taste will differ.
How thin should I slice the potatoes?
Slice potatoes about 1/8-inch thick for optimal tenderness and layering. Use a mandoline slicer for consistency, which ensures even cooking and a beautiful texture throughout the gratin.
Can I add other ingredients to this Potato Gratin Recipe?
Definitely! For extra flavor, try layering caramelized onions, sautéed mushrooms, or cooked bacon between the potato layers. Just be mindful of moisture content so the gratin remains creamy but not watery.

Instructions

- Bake Uncovered: Remove the foil and continue baking uncovered for an additional 25–30 minutes. Bake until the top is golden brown and the potatoes are tender when pierced with a knife.
- Rest Before Serving: Let the potato gratin rest for about 10 minutes after baking to allow it to set, making it easier to slice and serve.
