- 1.25 kg (2.5 lb) starchy potatoes: Russet, Sebago, or Maris Piper work best for the perfect tender yet firm texture.
- 1 tsp salt: Brings out the natural flavors without overpowering.
- 1/4 tsp pepper: Adds a subtle, mild heat that complements the creaminess.

How to Make Potatoes Au Gratin (Dauphinoise) Recipe
Step 1: Prepare the Cream Mixture
Start by simply whisking together the melted butter, cream, and minced garlic in a jug. This mixture is the flavor-packed bathing sauce for your potatoes, so make sure the garlic is well incorporated to infuse every layer with that lovely aroma.
Step 2: Preheat Your Oven
Set your oven to 180°C (350°F), whether it’s fan or standard. Preheating ensures an even bake, allowing the potatoes to soften beautifully while the cheese melts just right.
Step 3: Slice the Potatoes Thinly
Peel your potatoes and slice them as thinly as possible—ideally about 3mm thick, or 1/8 inch. Using a mandoline slicer here is a game-changer to keep the slices uniform so they cook evenly. The starchy potatoes will soak up the cream and bake into luscious layers.
Step 4: Layer the Ingredients
Grab a nice baking dish and start your first layer by spreading one-third of the potato slices evenly. Drizzle one-third of your cream mixture over them, then sprinkle with some salt, pepper, and a few thyme leaves. Follow it up with about three-quarters of a cup of the grated gruyere cheese. Repeat this process two more times, but save the final sprinkle of cheese for the very end—this will create that much-celebrated golden crust.
Step 5: Bake Covered
Cover the dish tightly with a lid or foil to lock in the steam. Pop it in the oven for about 1 hour to 1 hour and 15 minutes, or longer if needed until the potatoes are tender when poked with a knife. This slow baking allows the cream to thicken and the potatoes to become meltingly soft.
Step 6: Finish with Cheese
Remove the cover and generously sprinkle the remaining cheese over the top. Return it to the oven for another 10 to 15 minutes until you see that gorgeous golden, bubbling crust. Once out of the oven, let it stand for 5 minutes before serving—this resting time helps everything set up and enhances the flavors.
How to Serve Potatoes Au Gratin (Dauphinoise) Recipe
Garnishes
Sprinkle a few fresh thyme leaves right before serving to add a pop of green and fresh herbal notes. For a little extra flair, a light dusting of freshly ground black pepper can complement the cheese’s richness beautifully.
Side Dishes
This dish pairs wonderfully with roasted meats like chicken, beef, or a juicy pork tenderloin. You can also serve it alongside a crisp green salad or sautéed green beans to balance out the creamy richness with some freshness and crunch.
Creative Ways to Present
If you’re feeling fancy, portion the Potatoes Au Gratin (Dauphinoise) Recipe into individual ramekins for an elegant presentation. You can also bake it in a cast-iron skillet for a rustic touch, letting the edges get extra crispy and irresistible.
Make Ahead and Storage
Storing Leftovers
Leftover potatoes au gratin store beautifully in an airtight container in the refrigerator for up to 3 days. The flavors actually meld further, making the next day’s meal just as delightful.
Freezing
You can freeze this dish, but be mindful that the potatoes’ texture might be a bit softer after thawing. Freeze in a well-sealed container for up to a month and thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers covered in the oven at 175°C (350°F) until warmed through to preserve that creamy texture and melt the cheese again. Microwaving works too but may lead to uneven heating and a less crispy topping.
FAQs
Can I use other types of cheese for this recipe?
Absolutely! While gruyere is classic for its nutty flavor and meltability, you can substitute with cheeses like cheddar, Colby, Havarti, or Tasty. Just make sure they melt well to keep that creamy texture.
Do I have to peel the potatoes?
Peeling is traditional for a smooth texture, but if you like a bit of rustic charm and extra nutrients, you can leave the skins on as long as they’re washed and scrubbed well.
Can I make this recipe vegan or dairy-free?
For a vegan version, try swapping the cream and butter for plant-based alternatives like coconut cream and vegan butter, and choose a dairy-free cheese that melts well. The texture and flavor will be slightly different but still delicious.
What is the difference between Potatoes Au Gratin and Dauphinoise?
They’re often used interchangeably, but traditionally, Dauphinoise uses cream and no cheese, while Potatoes au Gratin includes cheese. This recipe brilliantly blends both elements for maximum indulgence.
How thin should I slice the potatoes?
About 3mm or 1/8 inch thick is ideal. Thin slices ensure the potatoes cook evenly and soak up the cream mixture perfectly, resulting in a tender, melt-in-your-mouth texture.

Ingredients
Potatoes au Gratin Ingredients
- 1 1/2 cups full-fat cream
- 2 garlic cloves, minced
- 30g / 2 tbsp unsalted butter, melted
- 1.25 kg / 2.5 lb starchy potatoes (Russet, Sebago, or Maris Piper)
- 1 tsp salt
- 1/4 tsp pepper
- 2 1/2 cups Gruyere cheese, freshly grated (can substitute with Colby, Cheddar, Havarti, or Tasty cheese)
- 2 tsp fresh thyme leaves (optional but highly recommended)
Instructions
- Cream Mixture: In a jug, combine the melted butter, full-fat cream, and minced garlic. Mix well until fully combined to create a flavorful cream base for the potatoes.
- Preheat Oven: Set your oven to 180°C (350°F), suitable for both fan and conventional ovens, preparing it for baking the gratin evenly.
- Slice Potatoes: Peel the potatoes and slice them very thinly, about 1/8 inch (3 mm) thick. Using a slicer can help achieve uniform slices for even cooking.
- Layer One: In a baking dish, spread one-third of the potato slices evenly. Pour over one-third of the cream mixture. Sprinkle one-third of the salt, pepper, and thyme leaves evenly, followed by 3/4 cup of the grated Gruyere cheese.
- Layers Two and Three: Repeat the layering process two more times with the remaining potatoes, cream, salt, pepper, and thyme, but on the final top layer, omit the cheese for now.
- Cover and Bake: Cover the dish with a lid or foil and bake in the preheated oven for 1 hour and 15 minutes to 1 hour and 30 minutes. Test the potatoes in the center with a knife to ensure they are tender and cooked through.
- Add Cheese Topping and Finish Baking: Remove the foil, sprinkle the remaining cheese over the top layer, and bake uncovered for an additional 10 to 15 minutes until the cheese is golden brown and bubbly. Let the gratin stand for 5 minutes before serving to allow it to set.
