About This Gratin
This recipe elevates humble potatoes into a luxurious side dish. The key lies in the paper-thin slicing, which ensures every layer melts into the creamy sauce. A whisper of freshly grated nutmeg and white pepper adds warmth without overpowering the dairy. For the best texture, use starchy potatoes like Russets or Yukon Golds.

Step-by-Step
Step 1
Preheat the oven to 160°C (325°F). Peel the potatoes and slice them into very thin rounds—use a sharp knife, mandoline, or a vegetable peeler for wafer-thin slices. If you’d like to speed up the process, a quality food processor with a slicing disc is invaluable; check out our top picks for the best glass food processor for durability.
Step 2
Generously butter a large, deep baking dish. Season the dish lightly with salt. Arrange a layer of potato slices in an overlapping pattern. Season each layer with a pinch of salt and a sprinkle of white pepper. Continue layering until all potatoes are used. To keep your layers neat, a steady hand and a good oil sprayer can help coat the dish evenly; see our recommendation for the best oil sprayer for effortless greasing.
Step 3
In a small saucepan, melt the remaining butter over low heat. Whisk in the cream and freshly grated nutmeg. Slowly pour the cream mixture evenly over the layered potatoes. For a silky sauce, an immersion blender can ensure a perfect emulsion; learn more about the best non-toxic immersion blender for health-conscious cooking.
Step 4
Cover the dish tightly with aluminum foil. Bake for 40 minutes at 160°C. This gentle cooking allows the potatoes to absorb the cream without browning too quickly. For even heat distribution, a quality oven is essential; check out our review of the best 48-inch built-in refrigerator to complement your kitchen setup, though for baking, a convection oven is ideal.
Step 5
Remove the foil. Sprinkle the grated mozzarella evenly over the top. Return the gratin to the oven and continue baking until the cheese is melted and golden brown, about 15–20 minutes. Serve hot. For an extra crispy top, you can switch to the broiler for the last few minutes—a feature found in many best non-toxic air fryer models that double as convection ovens.
Tips for Perfect Gratin
- Even Slices: Use a mandoline for uniformity. For bulk prep, a food processor with a slicing disc (see our guide to best planetary mixer for other kitchen machines) can save time.
- Low and Slow: Do not rush the initial bake. Low heat ensures creamy potatoes without curdling the cream.
- Cheese Selection: Mozzarella gives a mild, elastic pull. For a sharper flavor, mix in Gruyère or Parmesan. If you’re storing leftovers, an undercounter ice maker machine can keep your kitchen organized.
- Nutmeg: Always grate fresh nutmeg for the best aroma. A microplane works wonders.
Variations
This gratin is wonderfully adaptable. Add a layer of sautéed mushrooms or leeks for earthiness. Swap the cream for a combination of milk and cream for a lighter version. For a dairy-free twist, use oat cream and plant-based cheese.

FAQ
Can I make this gratin ahead of time?
Yes. Assemble the gratin up to the point of baking (step 4). Cover and refrigerate for up to 24 hours. When ready to bake, add an extra 10 minutes to the covered baking time.
What potatoes work best?
Starchy potatoes like Russets or Yukon Golds give the creamiest texture. Waxy potatoes hold their shape more and may not become as tender.
Can I freeze leftover gratin?
Freezing is not recommended because the cream sauce may separate upon thawing. For best quality, store in the refrigerator for up to 3 days and reheat in the oven.
Why is my gratin watery?
This can happen if the potatoes were not dried after washing, or if the cream is too thin. Use full-fat cream (at least 30% fat) and pat the potato slices dry before layering.
How do I get a perfectly golden crust?
After adding the cheese, increase the oven temperature to 200°C (400°F) or use the broiler for the last 3–5 minutes. Watch closely to avoid burning. For kitchen tools that help achieve consistent browning, explore the best steam canner for preserving sides.
Can I use pre-shredded cheese?
Pre-shredded mozzarella often contains anti-caking agents that affect melting. For the best texture, grate your own mozzarella from a block.
What can I serve with this gratin?
It pairs beautifully with roasted chicken, grilled steak, or a simple green salad. For a complete meal, consider adding a protein and a glass of wine—perhaps a best George Howell coffee as a digestif.
