Ingredients You'll Need
Making this Potatoes au Gratin (Dauphinoise) Recipe is straightforward, thanks to a handful of simple but essential ingredients. Each one plays a key role in building layers of flavor, creaminess, and that invitingly golden crust.
- Cream (full fat, 1 ½ cups): Adds the rich, luscious base that bathes every potato slice in velvety goodness.
- Garlic cloves, minced (2): Infuses a gentle savory aroma that perks up every bite without overpowering it.
- Unsalted butter, melted (30g / 2 tbsp): Boosts the creaminess and helps meld ingredients seamlessly.
- Starchy potatoes (Russet, Sebago, or Maris Piper, 1.25 kg / 2.5 lb): Their high starch content ensures the layers bind beautifully and create a fluffy, tender texture.
- Salt (1 tsp): Elevates all the flavors while seasoning each potato layer perfectly.
- Pepper (¼ tsp): Adds a mild heat and depth to balance the richness.
- Gruyere cheese, freshly grated (2 ½ cups): Known for its nutty and slightly sweet flavor, this cheese melts into a luscious topping and interior.
- Thyme leaves, fresh (2 tsp, optional but highly recommended): Offers a subtle herbal brightness that complements the cream and cheese elegantly.
How to Make Potatoes au Gratin (Dauphinoise) Recipe
Step 1: Prepare the Cream Mixture
Start by combining the melted butter, full-fat cream, and minced garlic in a jug. Mixing these creates a flavorful liquid that will soak into the potato slices, carrying the essence of garlic and cream into every layer.
Step 2: Preheat Your Oven
Set your oven to 180°C (350°F) for both fan and standard settings. A consistent medium heat allows the dish to cook slowly, giving the potatoes time to soften without drying out the creamy goodness.
Step 3: Slice the Potatoes
Peeling the potatoes is a must to achieve a smooth texture. Slice them into thin 3 mm (about ⅛ inch) rounds; using a slicer makes this process much easier and guarantees even cooking. These thin layers will bake beautifully, absorbing the cream and melting into a tender blanket of flavor.
Step 4: Layer the Potatoes and Cream Mixture
Begin the layering by spreading one-third of the potato slices evenly in your baking dish. Pour over one-third of the cream mixture, then sprinkle with a portion of salt, pepper, and the fresh thyme leaves. Finally, scatter about ¾ cups of grated gruyere cheese on top. This layering ensures the dish cooks uniformly and every mouthful bursts with flavor.
Step 5: Repeat for the Second and Third Layers
Repeat the process two more times, layering potatoes, cream, seasoning, and cheese. Be sure to hold back the cheese on the final layer—you will add it later to create that perfect golden crust.
Step 6: Cover and Bake
Cover your dish tightly with a lid or foil and bake for about 1 hour and 15 minutes. The goal is to let the potatoes cook until tender all the way through—testing with a knife in the center is the best way to check. Depending on your oven and potato thickness, it might take up to 1 hour and 30 minutes.
Step 7: Add the Final Cheese Layer and Bake Until Golden
Remove the foil and sprinkle the remaining cheese generously on top. Return the dish to the oven uncovered, allowing the cheese to melt, bubble, and brown—this will take about 10 to 15 minutes. Once the top is golden and irresistible, let the dish rest for 5 minutes before serving to set perfectly.
How to Serve Potatoes au Gratin (Dauphinoise) Recipe
Garnishes
A sprinkle of finely chopped fresh parsley or additional thyme leaves adds a lively pop of color and a hint of herbal freshness. You can also scatter a few thin chives for a subtle oniony bite that pairs beautifully with the richness.
Side Dishes
This Potatoes au Gratin (Dauphinoise) Recipe pairs wonderfully with roasted vegetables, grilled chicken, or a simple green salad dressed lightly in lemon vinaigrette to balance out the creamy indulgence. Lean proteins and crisp, acidic elements help to brighten the meal overall.
Creative Ways to Present
Try serving this dish in individual ramekins for an elegant touch at dinner parties. You can also add a layer of caramelized onions or a few dots of truffle oil after baking for a gourmet twist. Turning it into a gratin casserole parfait by layering with sautéed spinach or mushrooms makes an exciting variation.
Make Ahead and Storage
Storing Leftovers
Leftover Potatoes au Gratin (Dauphinoise) keep exceptionally well in the fridge for up to 3 days. Store them in an airtight container to maintain moisture and prevent the top from drying out.
Freezing
This dish freezes nicely, although the texture of the potatoes can change slightly. Freeze in portion-sized airtight containers or wrapped tightly with foil for up to 2 months. Thaw overnight in the refrigerator before reheating to ensure even warming.
Reheating
Reheat gently in a low oven (about 160°C/325°F) with foil covering to keep the moisture locked in. This method helps restore the creamy texture and avoids drying out the gratin. Microwave reheating is possible but tends to sacrifice some of the original texture and crispiness.
FAQs
Can I use a different type of cheese for this Potatoes au Gratin (Dauphinoise) Recipe?
Absolutely! While gruyere is classic for its nutty richness, you can substitute with cheddar, havarti, colby, or tasty cheeses, each lending a slightly different flavor and melting texture to the dish.
Do I need to peel the potatoes?
Peeling is recommended to achieve a smooth creamy texture and avoid the slight chewiness that skins can add. It also helps the potatoes absorb the cream mixture consistently for that signature silky finish.
Can I prepare this recipe ahead of time and bake it later?
Yes, you can assemble the entire dish, cover tightly, and refrigerate it for up to 24 hours before baking. Just add the final cheese topping before the last bake step to ensure the perfect golden crust.
What’s the best type of potato to use?
Starchy potatoes such as Russet, Sebago, or Maris Piper are ideal because they break down nicely during baking to create a creamy texture without being gummy.
Is there a way to add extra flavor to the cream mixture?
Try infusing the cream with fresh herbs like thyme (included in the recipe) or bay leaves before mixing it with butter and garlic. Simply warm the cream gently with herbs, let it steep, and strain before assembling for an added layer of depth.

Instructions
- Prepare Cream Mixture: In a jug, combine the melted butter, full-fat cream, and minced garlic. Mix thoroughly to blend all the flavors well.
- Preheat Oven: Set your oven to 180°C (350°F), suitable for both fan and conventional ovens to ensure even baking.
- Slice Potatoes: Peel the potatoes and slice them evenly to about ⅛ inch (3 mm) thickness using a knife or slicer for uniform cooking.
- Layer 1: Spread one-third of the potato slices evenly in a baking dish. Pour over one-third of the cream mixture. Sprinkle one-third of the salt, pepper, and thyme, then scatter ¾ cup of the grated cheese evenly over the top.
- Layers 2 & 3: Repeat the layering process twice more with the remaining potatoes, cream mixture, salt, pepper, and thyme. Do not add the cheese on top of the final layer yet.

Notes
- Use full-fat cream for the creamiest and richest flavor.
- Starchy potatoes like Russet, Sebago, or Maris Piper work best because they absorb flavors well and become tender.
- Freshly grate the cheese for better meltability and taste; choose Gruyere or a similar melting cheese.
- Covering during the initial bake ensures the potatoes cook evenly without drying out.
- If the potatoes are not tender after 1 hour 15 minutes, continue to bake up to 1 hour 30 minutes before adding the cheese topping.
