How to Make Potatoes au Gratin

Making Potatoes au Gratin (Dauphinoise) is easier than you think. Follow these steps to create a perfectly layered, creamy dish that will wow your guests.

Step 1: Prepare the Cream Mixture

In a jug or small bowl, combine the melted butter, cream, and minced garlic. Mix well to combine. This will be the flavorful liquid that infuses the potatoes with richness.

Step 2: Preheat the Oven

Preheat your oven to 180°C (350°F). This temperature ensures even cooking and a perfectly golden top.

Step 3: Slice the Potatoes

Peel the potatoes and slice them thinly, about 1/8 inch (3 mm) thick. Use a mandoline slicer for consistent results. Thin slices ensure the potatoes cook evenly and absorb the creamy mixture.

Step 4: Layer the Potatoes

• Layer 1: Spread 1/3 of the potato slices evenly in a baking dish. Pour over 1/3 of the cream mixture, then sprinkle 1/3 of the salt, pepper, and thyme leaves (if using). Add 3/4 cup of grated Gruyère cheese.
• Layers 2 & 3: Repeat the process for the second and third layers, reserving the remaining cheese for later.

Step 5: Bake the Potatoes

Cover the baking dish with foil or a lid and bake for 1 hour 15 minutes to 1 hour 30 minutes. Check for doneness by inserting a knife into the center—the potatoes should be soft and tender.

Step 6: Add the Final Layer of Cheese

Remove the foil, sprinkle the remaining cheese over the top, and bake uncovered for another 10–15 minutes until the cheese is golden and bubbly.

Step 7: Let It Rest

Allow the dish to rest for 5 minutes before serving. This helps the layers set and makes it easier to scoop.

Pro Tips for the Best Potatoes au Gratin

1. Choose the Right Potatoes: Use starchy varieties like Russet, Sebago, or Maris Piper. They absorb the creamy mixture beautifully, resulting in tender, flavorful layers.
2. Grate Your Own Cheese: Pre-grated cheese often contains anti-caking agents that prevent it from melting smoothly. Grate your Gruyère fresh for the best results.
3. Don’t Rush the Baking Time: The slow cooking process ensures the potatoes become soft and absorb all the flavors.
4. Customize the Herbs: If you don’t have thyme, rosemary or parsley work just as well.
5. Use Full-Fat Cream: Low-fat substitutes may result in a less creamy dish.
