Ingredients You’ll Need
Though this recipe might look fancy on the plate, the ingredients are delightfully simple and accessible. Each plays a key role in building layers of texture and flavor—from the creamy sauce that soaks into the potatoes to the cheeses that create that irresistible crust.
- 3 lbs Yukon Gold or Russet potatoes: These varieties hold their shape beautifully while absorbing the cream, offering a perfect balance of creaminess and structure.
- 1 cup heavy cream: Adds luscious richness that makes each bite melt in your mouth.
- 1 1/2 cups whole milk: Lightens the sauce just enough while keeping it smooth and velvety.
- 2 tablespoons unsalted butter: Used to sauté garlic and thyme, infusing the sauce with gentle depth.
- 2 garlic cloves, minced: Brings fragrant warmth without overpowering the dish.
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme): Adds an herby note that perfectly complements the cheese and potatoes.
- 1/2 teaspoon salt: Enhances all the natural flavors in the gratin.
- 1/4 teaspoon black pepper: A subtle kick to balance the richness.
- 1 cup grated Gruyere cheese: This creamy, nutty cheese melts beautifully creating velvety pockets of flavor.
- 1 cup grated Parmesan cheese: Provides a salty, crispy topping that gives the gratin its signature crunch.
- 1/2 cup breadcrumbs (optional): For an extra golden, crispy crust that’s hard to resist.
- 1 tablespoon fresh parsley (optional): A fresh, bright garnish to finish the dish with a pop of color.
How to Make Crispy Parmesan and Gruyere Potato Gratin Recipe
Step 1: Preheat and Prepare the Dish
Start by preheating your oven to 375 degrees Fahrenheit (190 degrees Celsius). While that heats up, grease a 9 by 13-inch baking dish with butter or cooking spray to ensure your gratin won’t stick and will develop that gorgeous golden crust.
Step 2: Slice the Potatoes Thinly
Peeling and slicing the potatoes into uniform, thin slices—about one-eighth of an inch thick—is essential here. Using a sharp knife or a mandoline slicer makes this task much easier and ensures even cooking. Thin slices allow the creamy sauce to seep into every layer, creating perfect tenderness throughout.
Step 3: Make the Creamy Garlic and Thyme Sauce
In a saucepan set over medium heat, melt the butter and gently cook the minced garlic and thyme for about a minute until fragrant. Then pour in the heavy cream and whole milk, stirring to combine everything smoothly. Season thoughtfully with salt and black pepper. Bring this mixture just to a gentle simmer, letting the flavors meld together for a couple of minutes before turning off the heat.
Step 4: Layer the Potatoes in the Baking Dish
Now comes the satisfying layering process. Lay down the first layer of potato slices in the prepared dish, slightly overlapping them so that no space is left uncovered. Keep layering thin potato slices until you’ve used every last one, building a beautiful stack ready to absorb all the delicious sauce to come.
Step 5: Pour Sauce and Add Cheese Toppings
Carefully pour the creamy garlic and thyme sauce evenly over the layered potatoes, ensuring every slice gets coated. Generously sprinkle the grated Gruyere and Parmesan cheeses across the top. If you want that extra satisfying crunch, go ahead and scatter the optional breadcrumbs over the cheese—it will bake into an irresistible golden topping.
Step 6: Bake to Golden Perfection
Cover your gratin with aluminum foil to keep the moisture locked in, and bake for 45 minutes. Then remove the foil and continue baking for another 15 to 20 minutes. This final stage is where your Crispy Parmesan and Gruyere Potato Gratin Recipe really comes to life—the top should bubble and turn a mouthwatering golden brown while the potatoes beneath become tender enough to pierce easily with a fork.
Step 7: Rest and Garnish
Once baked, give your gratin a little breathing room by letting it rest for about 10 minutes. This pause helps the flavors settle and makes serving easier. For a fresh burst of color and brightness, sprinkle on some freshly chopped parsley before bringing it to the table.
How to Serve Crispy Parmesan and Gruyere Potato Gratin Recipe
Garnishes
Adding freshly chopped parsley is a simple way to brighten up the dish visually and add just a hint of herbal freshness that cuts through the richness. You could also experiment with a sprinkle of finely chopped chives or a dash of smoked paprika for a subtle twist.
Side Dishes
This gratin pairs beautifully with roasted meats like a juicy roast chicken or tender beef brisket, balancing the hearty proteins with its creamy texture. A crisp green salad or steamed seasonal vegetables also provide a refreshing contrast that keeps the meal well-rounded and satisfying.
Creative Ways to Present
For a cozy family meal, serve this gratin straight from the baking dish for that rustic, comforting vibe. Alternatively, you can portion it into elegant ramekins for individual servings—perfect for a dinner party where presentation matters as much as flavor. Either way, each portion promises a crispy, cheesy bite you won’t forget.
Make Ahead and Storage
Storing Leftovers
Leftover Crispy Parmesan and Gruyere Potato Gratin Recipe keeps well when cooled completely and stored in an airtight container in the refrigerator. It will stay fresh and delicious for up to 3 days, giving you plenty of opportunities to enjoy those cheesy, crispy layers all over again.
Freezing
If you want to prepare ahead, this gratin freezes wonderfully. Assemble it fully, then cover it tightly with aluminum foil before freezing. It’s best used within 1 to 2 months. When ready to eat, thaw it overnight in the refrigerator before reheating, so it retains that amazing texture and flavor.
Reheating
To reheat, place your portion in the oven at 350 degrees Fahrenheit (175 degrees Celsius) until warmed through. This method keeps the topping crispy and the inside creamy, avoiding the dreaded sogginess that a microwave can cause. A 20 to 30-minute reheat time usually does the trick.
FAQs
Can I use other types of potatoes for this gratin?
Yes! Yukon Gold and Russet potatoes are preferred because they hold texture well and absorb the creamy sauce nicely, but you could also try red potatoes for a slightly different texture. Just be sure to slice them thinly for even cooking.
Is it necessary to use both Parmesan and Gruyere cheeses?
Using both cheeses creates a wonderful flavor contrast—Gruyere offers a mellow, nutty creaminess, while Parmesan adds sharpness and contributes to that golden crispy crust. Together, they make this gratin truly special, though you could experiment with similar cheeses if needed.
Can I make this recipe dairy-free or vegan?
This recipe relies heavily on dairy for its creamy texture and rich flavor, so substitutions would change it significantly. You might try plant-based creams and vegan cheeses, but note the texture and taste will differ from the classic Crispy Parmesan and Gruyere Potato Gratin Recipe.
What if I don’t have fresh thyme?
Dried thyme is a great substitute—you’ll just need about half the amount since dried herbs are more concentrated. If you don’t have thyme at all, feel free to omit it or use a pinch of rosemary or sage for a different herbal note.
Can I add other ingredients like onions or bacon?
Absolutely! Thinly sliced onions or sautéed bacon make delicious additions, adding extra layers of flavor and texture. Just be mindful not to overwhelm the delicate balance of the original gratin—sometimes simplicity really is best with this recipe.

If you’re searching for a side dish that combines elegance with cozy comfort, this Crispy Parmesan and Gruyere Potato Gratin Recipe is an absolute must-try.

Ingredients
Potatoes
- 3 lbs Yukon Gold or Russet potatoes, peeled and thinly sliced
Creamy Sauce
- 1 cup heavy cream
- 1 1/2 cups whole milk
- 2 tablespoons unsalted butter
- 2 garlic cloves, minced
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Cheese Topping
- 1 cup grated Gruyere cheese
- 1 cup grated Parmesan cheese
- 1/2 cup breadcrumbs (optional, for extra crispy topping)
Garnish
- 1 tablespoon fresh parsley (optional, for garnish)
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking and ensure easy cleanup.
- Prepare the Potato Layers: Peel the potatoes and slice them thinly—about 1/8 inch thick—using a sharp knife or mandolin slicer for uniform layers. Set the slices aside.
- Make the Creamy Sauce: In a saucepan over medium heat, melt the butter. Add the minced garlic and thyme, cooking for about 1 minute until fragrant. Pour in the heavy cream and milk, stirring well to combine. Season with salt and black pepper, then bring the mixture to a gentle simmer. Let it cook for 2-3 minutes to meld the flavors before removing from heat.
- Layer the Potatoes: Begin by arranging a layer of potato slices evenly in the bottom of the prepared baking dish, slightly overlapping each slice. Continue layering until all the potatoes are used, forming even layers.
- Add the Cheese and Cream: Pour the creamy sauce evenly over the potato layers, making sure it seeps through the layers. Sprinkle the grated Gruyere and Parmesan cheese evenly over the top. If you prefer an extra crispy crust, sprinkle the breadcrumbs evenly over the cheese.
- Bake the Gratin: Cover the baking dish tightly with aluminum foil and bake for 45 minutes. Then remove the foil and bake for an additional 15-20 minutes, until the top is golden brown and crispy and the potatoes are tender when pierced with a fork.
- Serve: Allow the gratin to rest for about 10 minutes before serving. Garnish with freshly chopped parsley if desired, then slice and serve warm.
Notes
- Use a mandolin slicer for even potato slices to ensure uniform cooking.
- For a richer flavor, you can substitute half-and-half for the milk or add a bit of nutmeg to the cream sauce.
- The breadcrumbs are optional but add a nice crunchy texture to the top layer.
- Allowing the gratin to rest before serving helps it set and makes slicing easier.
- To make this dish gluten-free, omit the breadcrumbs or use gluten-free breadcrumbs.
