Ingredients You’ll Need
The magic of this dish comes from simple, high-quality ingredients that work together for maximum taste and texture. Each component brings a unique character to the dish:
- Yukon Gold potatoes: Their buttery texture and natural sweetness make them ideal for creamy gratins.
- Heavy cream: Adds richness and helps create that silky, luscious sauce.
- Kosher salt: Essential for seasoning and bringing out the natural flavors of the potatoes and cream.
- Freshly ground black pepper: Lends a gentle heat and sharpness that balances the creaminess.
- Freshly grated nutmeg: A generous pinch introduces a warm, aromatic depth to the dish.
- Cayenne pepper: Just a touch to awaken the palate without overpowering.
- Garlic cloves: Smashed and minced for a subtle, savory boost throughout the gratin.
- Gruyère cheese: Freshly shredded for that signature crisped, nutty crust on top.
- Fresh basil: To garnish and add a fresh, herbal brightness to finish.
How to Make Gruyère-Crisped Potatoes Au Gratin Recipe
Step 1: Prepare the Potatoes
Start by preheating your oven to 400°F and thoroughly washing your Yukon Gold potatoes. For perfectly even slices about 1/8 inch thick, use a food processor with a slicer blade, or if you prefer, a sharp knife or mandoline works beautifully. Consistency here ensures the potatoes cook evenly, soaking up all the flavors of the creamy base.
Step 2: Simmer the Cream and Potatoes
In a large pot, combine the sliced potatoes with heavy cream, kosher salt, freshly ground black pepper, grated nutmeg, cayenne pepper, and minced garlic. Gently bring this mixture to a boil over medium-high heat, stirring carefully to avoid breaking the delicate slices. This step infuses the potatoes with rich, spiced cream, creating the foundation of your gratin’s luscious texture.
Step 3: Assemble the Dish
Transfer the creamy potato mixture into a 2.5 or 3-quart baking dish, shaking it lightly to nestle the potatoes in place. Then, generously sprinkle the freshly shredded Gruyère cheese over the top. This layer is the secret to that coveted golden, crispy crust that makes this gratin irresistible.
Step 4: Bake Until Golden and Tender
Place your dish in the oven and bake at 400°F for approximately 40 minutes. You’re aiming for the potatoes to be fork-tender and the top to develop a deep, dark brown crust. Don’t worry if the sauce looks loose when you pull it out — it will thicken up as it cools, sealing in the richness and flavors perfectly.
Step 5: Rest and Garnish
Allow the gratin to rest for about 15 minutes before serving. This pause helps the sauce set just right. Finish with a sprinkle of fresh chopped basil to add a fresh touch that beautifully contrasts the rich, cheesy potatoes.
How to Serve Gruyère-Crisped Potatoes Au Gratin Recipe
Garnishes
A sprinkle of fresh basil leaves brightens up the dish with herbal notes and a pop of green color. For extra flair, consider a light dusting of finely grated Parmesan or a few crispy sage leaves to add texture and visual appeal.
Side Dishes
Because the Gruyère-Crisped Potatoes Au Gratin Recipe is so indulgently rich, pairing it with crisp, fresh salads or roasted vegetables balances the meal wonderfully. Think simple arugula with lemon vinaigrette, steamed green beans, or lightly sautéed spinach to keep the plate vibrant and harmonious.
Creative Ways to Present
Serve this gratin in individual ramekins for elegant single servings, or bake it in a cast iron skillet right at the table for a rustic presentation that invites sharing. You might also add layers of caramelized onions or sautéed mushrooms within the dish to personalize it with added earthiness and depth.
Make Ahead and Storage
Storing Leftovers
If you find yourself lucky enough to have leftovers, cool the potatoes completely, then cover and refrigerate for up to 3 days. The creamy sauce tends to thicken overnight, so the gratin keeps well and tastes even better the next day once reheated.
Freezing
This gratin freezes beautifully, making it perfect for prepping in advance. Cook the potatoes fully, cool, then cover tightly with foil and store in the freezer for up to 2 months. Thaw overnight in the fridge before reheating to preserve all the flavors and textures.
Reheating
To reheat, warm the gratin in a 350°F oven uncovered for about 20 minutes until heated through and the crust regains some crispiness. Microwaving is quicker but can make the topping lose its crisp texture, so oven reheating is always preferred to capture that signature Gruyère crunch.
FAQs
Can I use a different type of potato?
Yukon Gold potatoes are ideal for their creamy texture and buttery flavor, but you can substitute with other waxy potatoes like red potatoes or fingerlings. Avoid starchy potatoes like Russets, which may become too mushy.
What if I don’t have Gruyère cheese?
Gruyère’s nutty, melt-in-your-mouth quality is key to this recipe, but you can use Emmental or a good-quality Swiss cheese as a substitute. Just make sure it melts well to get the right texture and color on top.
Is there a way to make this recipe lighter?
Yes! You can swap heavy cream for half-and-half or whole milk with a touch of flour to maintain creaminess. The gratin won’t be quite as rich, but it will still be delicious and satisfying.
Can I add other flavors or ingredients?
Absolutely! Adding caramelized onions, sautéed mushrooms, or fresh herbs like thyme or rosemary can deepen the flavor. Just keep the balance so the creamy potato and cheese combo remains the star.
How do I know when the gratin is done?
The top should be a deep golden brown and crispy, and the potatoes should be fork-tender. The cream will thicken during baking and set upon cooling, so a bubbling but slightly loose sauce right out of the oven is perfect.
Final Thoughts
If you’re ready to impress family and friends with a dish that feels both luxurious and comforting, the Gruyère-Crisped Potatoes Au Gratin Recipe is your perfect go-to. It’s a beautiful combination of creamy textures, bold flavors, and that signature crispy cheesy top that brings a special touch to any meal.

Ingredients
Potatoes
- 2 pounds Yukon Gold potatoes
Cream Mixture
- 3 cups heavy cream
- 1 teaspoon kosher salt
- 1/8 teaspoon freshly ground black pepper
- Generous pinch freshly grated nutmeg
- 1/4 teaspoon cayenne pepper
- 2 cloves garlic, smashed and minced
Cheese and Garnish
- 3/4 cup Gruyère cheese, freshly shredded
- Fresh basil, to garnish
Instructions
- Prepare the oven and potatoes: Preheat your oven to 400°F. Wash and scrub the Yukon Gold potatoes thoroughly. Using a food processor fitted with a slicer blade, slice the potatoes 1/8 inch thick by feeding them through 1 or 2 at a time. If you don’t have a food processor, carefully slice using a sharp knife or mandoline.
- Cook the potatoes in cream mixture: In a large pot, combine the sliced potatoes, heavy cream, kosher salt, freshly ground black pepper, freshly grated nutmeg, cayenne pepper, and minced garlic. Set the pot over medium-high heat and cook gently, stirring occasionally to avoid breaking the potatoes, until the cream mixture comes to a boil.
- Transfer to baking dish and add cheese: Pour the creamy potato mixture into a 2.5 to 3 quart baking dish. Shake the dish gently to evenly distribute and settle the potatoes. Sprinkle the shredded Gruyère cheese evenly on top.
- Bake until golden and tender: Place the baking dish in the preheated oven and bake for about 40 minutes until the potatoes are fork-tender. The top should be deeply golden brown, and the cream should have thickened. The sauce will continue to thicken as it cools.
- Rest and garnish: Remove the dish from the oven and let the potatoes stand about 15 minutes to set. Just before serving, garnish with freshly chopped basil for a fragrant finish.
Notes
- Use Yukon Gold potatoes for their creamy texture and ability to hold their shape during cooking.
- Slicing potatoes uniformly ensures even cooking; a mandoline or food processor slicer blade is ideal.
- Be gentle when stirring the cream and potatoes to avoid breaking the slices.
- The sauce may appear loose right out of the oven but will thicken as it cools.
- For a sharper flavor, you can substitute part of the Gruyère with Parmesan cheese.
- Letting the dish rest before serving helps the au gratin set and improves slicing.
