Ingredients You’ll Need
To create this unforgettable gratin, you only need a handful of simple, wholesome ingredients—all of which come together in harmony to build layers of flavor, texture, and even a touch of herbal brightness. Each ingredient plays a star role, ensuring every bite is perfectly balanced and irresistibly delicious.
- Yukon Gold potatoes: Their buttery texture and natural sweetness make them ideal for layering and absorbing flavors.
- Heavy cream: Provides the luscious, velvety richness that binds the dish together.
- Gruyere cheese: Adds a creamy, slightly sweet nuttiness and melts beautifully for that gooey factor.
- Parmesan cheese: Brings a sharp, savory punch and creates the crispy golden crust everyone loves.
- Garlic clove: Infuses the gratin with gentle aromatic warmth for depth of flavor.
- Fresh thyme leaves: Adds a subtle herbaceous note that lifts the richness without overpowering.
- Salt: Essential for enhancing every element’s natural flavor.
- Black pepper: Offers a mild kick and rounds out the seasoning.
- Unsalted butter: Dotting the top with butter helps achieve that irresistible crisp finish and indulgent mouthfeel.
How to Make Crispy Parmesan and Gruyere Potato Gratin Recipe
Step 1: Prepare your baking dish and preheat the oven
Start by preheating your oven to 375°F (190°C). Rub the inside of your baking dish with the cut side of a garlic clove to impart subtle garlicky aroma. Then, lightly butter the dish to ensure the gratin doesn’t stick and adds a touch of richness from the beginning.
Step 2: Slice the potatoes thinly and evenly
Using a mandoline or a sharp knife, slice the Yukon Gold potatoes into thin rounds, about 1/8-inch thick. Precision here matters because evenly sliced potatoes cook uniformly, resulting in that perfect tender-yet-structured texture that’s key to a great gratin.
Step 3: Layer potatoes with seasonings and cheese
Arrange half of your potato slices in the baking dish with each slice slightly overlapping the next. Season them evenly with half of the salt, pepper, thyme, and minced garlic for flavor to penetrate every bite. Then sprinkle half of the Gruyere and Parmesan cheeses over the potatoes, building rich layers.
Step 4: Repeat layering and add cream
Repeat the layering process with the remaining potatoes, seasonings, and cheeses. Once layered, pour the heavy cream evenly over everything. This creamy bath ensures the gratin bakes up moist and velvety inside.
Step 5: Add finishing touches and bake
Dot the top with small pats of unsalted butter and a generous sprinkle of extra Parmesan cheese to encourage a crispy, golden crust. Cover the dish with foil and bake for 30 minutes, allowing the potatoes to soften within the creamy layers.
Step 6: Uncover and brown to perfection
Remove the foil and bake uncovered for another 20 to 25 minutes. This is when the magic happens—the top bubbles, the cheeses brown and crisp, and the entire gratin develops that coveted crunchy, cheesy crust that makes this Crispy Parmesan and Gruyere Potato Gratin Recipe unforgettable.
Step 7: Let it rest before serving
Once baked, allow the gratin to rest for 10 to 15 minutes so the layers set nicely. This resting time ensures clean slices and a creamy texture that holds together beautifully when you serve.
How to Serve Crispy Parmesan and Gruyere Potato Gratin Recipe
Garnishes
To elevate your presentation, a light sprinkle of fresh thyme leaves or finely chopped chives adds a pop of color and a fresh herbal aroma. A drizzle of high-quality olive oil or a dusting of freshly cracked black pepper right before serving can also enhance the dish’s appeal.
Side Dishes
This gratin pairs wonderfully with a variety of mains—think roasted chicken, seared steak, or even a simple green salad for balance. Its rich, creamy nature complements lighter protein and fresh vegetables, making it a versatile side that shines in any meal setting.
Creative Ways to Present
Try serving individual portions of this Crispy Parmesan and Gruyere Potato Gratin Recipe in small ramekins for an elegant touch, perfect for dinner parties. Alternatively, present it family-style in the baking dish for a cozy, communal vibe. For holiday feasts, garnish with edible flowers or microgreens for a sophisticated flair.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover gratin tightly with plastic wrap or foil and store it in the refrigerator. It will remain fresh for up to 3 days, ready to bring its comforting charm back to your table.
Freezing
This potato gratin freezes well when wrapped properly. For best results, place the cooled dish in an airtight container or wrap tightly with heavy-duty foil and plastic wrap. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
To reheat, bake the gratin uncovered at 350°F (175°C) for 20 to 25 minutes or until warmed through and the top crisps up again. Avoid microwaving if you want to retain that signature crispiness that makes the Crispy Parmesan and Gruyere Potato Gratin Recipe so special.
FAQs
Can I use other types of potatoes for this gratin?
While Yukon Gold potatoes are preferred for their creamy texture and buttery flavor, you can substitute with Russet potatoes. Just keep in mind that Russets may be starchier and drier, so the texture may differ slightly.
Is there a substitute for heavy cream?
You can use half-and-half or a mixture of milk and butter as a lighter alternative, but heavy cream delivers the richest, creamiest results essential for this recipe’s signature feel.
Can I make this Crispy Parmesan and Gruyere Potato Gratin Recipe vegetarian?
Absolutely! This recipe is naturally vegetarian as it uses dairy products for richness. Just ensure your cheeses are suitable for a vegetarian diet, checking that no animal rennet was used.
How thin should I slice the potatoes?
Slicing them about 1/8-inch thick ensures that the potatoes cook evenly and tenderly while still holding structure. This thickness strikes the perfect balance between creamy and firm layers.
Can I prepare the gratin a day ahead?
Definitely! Assemble the gratin a day before, keep it covered in the refrigerator, and bake it fresh when you’re ready to serve. Just add a bit of extra baking time if starting from cold.

Dairy
- 1 1/2 cups heavy cream
- 1 cup shredded Gruyere cheese
- 1/2 cup freshly grated Parmesan cheese
- 2 tablespoons unsalted butter, cut into small pats
Instructions
- Prepare Baking Dish: Preheat your oven to 375°F (190°C). Rub the inside of a baking dish with the cut side of a garlic clove to infuse subtle garlic flavor, then lightly butter the dish to prevent sticking and add richness.
- Slice Potatoes: Using a mandoline slicer or a sharp knife, slice the Yukon Gold potatoes into 1/8-inch thick rounds for even layering and optimal texture.
- First Potato Layer: Arrange half of the potato slices in the baking dish, slightly overlapping each slice. Season this layer evenly with half of the salt, pepper, thyme, and minced garlic to distribute the flavors.
- Cheese Layer: Sprinkle half of the shredded Gruyere and grated Parmesan cheese over the seasoned potato layer to add creaminess and flavor.
- Second Potato Layer: Repeat the layering process by placing the remaining potato slices on top, seasoning again with the rest of the salt, pepper, thyme, and garlic for consistency in flavor.
- Second Cheese Layer: Add the remaining Gruyere and Parmesan cheese evenly over the second potato layer to ensure the gratin is rich and cheesy throughout.
- Add Cream: Pour the heavy cream evenly across the entire layered dish to soak into the potatoes, creating a creamy texture as it cooks.
- Add Butter and Parmesan Crust: Dot the top of the gratin with small pats of unsalted butter and sprinkle extra Parmesan cheese for that signature golden, crispy crust.
- Initial Bake: Cover the dish tightly with foil to retain moisture and bake in the preheated oven for 30 minutes, allowing the potatoes to start cooking through.
- Finish Baking: Remove the foil and continue baking for an additional 20 to 25 minutes until the top is golden brown and bubbly, indicating the gratin is cooked perfectly.
- Rest: Allow the gratin to rest for 10 to 15 minutes after baking. This resting time lets the layers set, making it easier to slice and serve without falling apart.
Notes
- Use Yukon Gold potatoes for their creamy texture and buttery flavor which hold up well in gratins.
- Thinly slice potatoes evenly to ensure uniform cooking.
- Resting the gratin after baking helps firm up the layers for neat serving.
- Feel free to substitute Gruyere with Emmental cheese if unavailable.
- For a lighter version, reduce heavy cream slightly or substitute part with milk but expect a less rich texture.
