Ingredients You'll Need
Don’t let the simplicity of this recipe fool you; each ingredient plays a starring role in building layers of flavor, creaminess, and that irresistible cheesy crust. You’ll find that the magic really comes from fresh, quality components working in harmony.
- 1 ½ cups full-fat cream: Adds luscious creaminess and helps the potatoes become tender while baking.

- 1.25 kg starchy potatoes: Russet, Sebago, or Maris Piper are ideal; their starchiness helps achieve that perfect creamy texture.
- 1 teaspoon salt: Essential for seasoning the layers and enhancing natural flavors.
- ¼ teaspoon pepper: Adds a gentle warmth without overpowering the cheese and cream.

How to Make Potatoes au Gratin (Dauphinoise) Recipe
Step 1: Prepare the Cream Mixture
Start by combining melted butter, full-fat cream, and minced garlic in a jug. Stir them together until well mixed. This creamy, garlicky blend is what will gently cook the potatoes while infusing them with deep flavor throughout the bake.
Step 2: Preheat Your Oven
Set your oven to 180°C (350°F). Whether you have a fan-assisted or a standard oven, this temperature creates the perfect environment to slowly bake the potatoes until they're irresistibly tender and the cheese topping turns golden.
Step 3: Slice the Potatoes Thinly
Peel your potatoes, then slice them about ⅛-inch (3 mm) thick. Using a slicer helps ensure even thickness, which means even cooking. Thin slices allow the cream mixture to seep between layers, making every mouthful melt-in-your-mouth delicious.
Step 4: Build the First Layer
Grease your chosen baking dish and layer one-third of the potatoes evenly on the bottom. Pour over one-third of the cream mixture, then sprinkle with one-third each of the salt, pepper, and thyme. To finish this layer, scatter about ¾ cup of your freshly grated gruyere cheese, setting the stage for melty, cheesy perfection.
Step 5: Repeat for Layers Two and Three
Repeat the layering process two more times: potatoes, cream mixture, seasoning, and cheese. For the topmost layer, don’t add cheese yet—that’s saved for the grand finale to create a gorgeous golden crust.
Step 6: Bake Covered Until Tender
Cover the dish tightly with a lid or foil and bake for about 1 hour 15 minutes to 1 hour 30 minutes. You’ll know it’s perfectly done when a knife slides easily through the potatoes without resistance. Slow baking lets the cream soak in, transforming the potatoes into a tender, velvety experience.
Step 7: Add Cheese Topping and Finish Baking
Remove the cover, sprinkle the final amount of cheese evenly on top, and return the dish to the oven. Bake for another 10 to 15 minutes until the cheese is golden, bubbling, and wonderfully crispy around the edges. Let it stand for 5 minutes before serving to set beautifully.
How to Serve Potatoes au Gratin (Dauphinoise) Recipe
Garnishes
To enhance the presentation and add a fresh contrast, sprinkle a few extra thyme leaves or chopped chives just before serving. A light dusting of cracked black pepper right on top can also elevate each bite with a subtle hint of spice.
Side Dishes
Potatoes au Gratin (Dauphinoise) Recipe pairs wonderfully with roasted meats like chicken, beef, or pork. It’s also fantastic alongside steamed green veggies such as asparagus or green beans, balancing out its rich creaminess with fresh, crisp textures.
Creative Ways to Present
For a stunning dinner party, consider making individual portions baked in small ramekins. This not only looks chic but also allows each guest to enjoy their own perfectly browned, cheesy gratin, fresh out of the oven. Another idea is to sprinkle toasted breadcrumbs mixed with herbs on top before the final bake for extra crunch.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, don’t despair! Potatoes au Gratin (Dauphinoise) Recipe keeps well in an airtight container in the refrigerator for up to 3 days. The flavors actually meld and deepen overnight, making next-day servings taste even better.
Freezing
This dish freezes well if you want to save some for later. Cool completely before transferring to a freezer-safe container. It’s best consumed within 1 month for optimal texture and flavor. When ready to eat, thaw overnight in the fridge before reheating.
Reheating
Reheat your leftovers gently in a 160°C (325°F) oven until warmed through to maintain the creamy texture and melt the cheese topping back to life. Avoid microwaving to prevent the potatoes from drying out or becoming rubbery.
FAQs
Can I use other types of cheese for Potatoes au Gratin (Dauphinoise) Recipe?
Absolutely! While gruyere is traditional, cheeses like cheddar, colby, havarti, or tasty can work beautifully. Just choose cheeses that melt well and have a flavor you enjoy.
Is it necessary to peel the potatoes?
Peeling ensures the texture is smooth and creamy without the extra bite of skins. However, if you prefer a rustic feel, leaving the skins on is fine as long as the potatoes are washed thoroughly.
Can I prepare this dish ahead of time before baking?
Yes, you can assemble the entire dish, cover it, and refrigerate for up to 24 hours before baking. This makes it a perfect make-ahead side for busy entertaining.
Why use starchy potatoes like Russet or Maris Piper?
Starchy potatoes break down slightly during baking, creating that silky texture essential to Potatoes au Gratin (Dauphinoise) Recipe. Waxy potatoes tend to stay firm, which is less ideal here.
How do I know when the potatoes are fully cooked?
The best way is to insert a thin knife into the middle of the dish; it should slide in easily and the potatoes should feel tender but not mushy. If there’s resistance, give it additional baking time.
Final Thoughts
This Potatoes au Gratin (Dauphinoise) Recipe is truly one of those dishes that comforts the soul and impresses guests all at once.

Description
Potatoes au Gratin (Dauphinoise) is a classic French dish featuring thinly sliced starchy potatoes baked in a rich garlic cream sauce with layers of melted Gruyere cheese and fresh thyme. This creamy, cheesy gratin is baked to golden perfection, making it a comforting side dish ideal for family dinners or special occasions.
Ingredients
Cream Mixture
- 1 ½ cups full-fat cream
- 2 garlic cloves, minced
- 30g / 2 tablespoon unsalted butter, melted
Potatoes
- 1.25 kg / 2.5 lb starchy potatoes (Russet, Sebago, or Maris Piper), peeled and sliced ⅛" (3 mm) thick
Seasonings & Cheese
- 1 tsp salt
- ¼ tsp pepper
- 2 ½ cups Gruyere cheese, freshly grated (alternatives: Colby, Cheddar, Havarti, or Tasty cheese)
- 2 tsp fresh thyme leaves (optional but highly recommended)
Instructions
- Cream Mixture: Place the melted butter, full-fat cream, and minced garlic in a jug and mix them together until well combined. This will be the rich base that flavors the potatoes.
- Preheat Oven: Set your oven to 180°C (350°F), suitable for both fan-forced and standard ovens, to ensure even baking.
- Slice Potatoes: Peel the potatoes thoroughly and slice them evenly into ⅛ inch (3 mm) thick slices, either by hand or using a slicer for uniformity.
- Layer 1: Spread one-third of the sliced potatoes evenly in a baking dish. Pour over one-third of the cream mixture, then scatter one-third of the salt, pepper, and optional thyme leaves. Top with ¾ cup of the grated Gruyere cheese to create a flavorful layer.
- Layers 2 & 3: Repeat the layering process two more times with the remaining potatoes, cream mixture, salt, pepper, and thyme. For the final, third layer, do not add cheese yet; the cheese topping will be added later for a golden crust.
- Cover & Bake: Cover the baking 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 for tenderness by inserting a knife into the center; it should go through easily indicating they are cooked.
- Top with Cheese & Final Bake: Remove the foil or lid, evenly sprinkle the remaining cheese over the top layer, and return the dish to the oven. Bake for an additional 10 to 15 minutes until the cheese is golden, bubbly, and slightly crisp on top.
- Rest & Serve: Allow the gratin to stand for 5 minutes before serving to let it set slightly for cleaner slices and enhance the flavors.
Notes
- Use full-fat cream for a rich and creamy texture essential to this dish.
- Starchy potatoes like Russet, Sebago, or Maris Piper are ideal because they hold their shape well when baked and absorb flavors.
- Gruyere cheese melts beautifully and adds a classic nutty flavor, but Colby, Cheddar, Havarti, or Tasty cheese can be used as alternatives.
- If fresh thyme is unavailable, dried thyme can be substituted though the flavor will be less vibrant.
- The baking time to cook the potatoes fully can vary slightly depending on oven and potato thickness, so test with a knife for doneness.
