What You’ll Need
This classic French potato dish relies on simple, high-quality ingredients to shine. You’ll need creamy dairy, aromatic garlic, starchy potatoes, savory seasonings, and a generous amount of cheese to create its signature richness.
Ingredient Notes
- Cream – Full-fat cream is essential for achieving that luxurious, velvety texture. Don’t shy away from it!
- Potatoes – Starchy varieties like Russets, Sebago, or Maris Piper are ideal as they absorb the cream beautifully and become incredibly tender.
- Gruyere Cheese – Freshly grated Gruyere offers a wonderful nutty flavor, but feel free to use your favorite melting cheese like Colby, cheddar, or Havarti. Grating it yourself ensures the best meltability.
Add-ins and Substitutions
While this recipe is wonderfully classic as is, you can certainly customize it to your liking. For a touch of extra flavor, consider adding a pinch of nutmeg to the cream mixture. If you don’t have fresh thyme, a smaller amount of dried thyme can be used, though fresh truly brings out a brighter herbiness.
How to Make Creamy Potatoes Dauphinoise
Get ready to create a showstopping side dish that’s surprisingly simple to put together. Follow these steps for a taste of pure comfort.
- Prepare the Cream Mixture: In a jug, whisk together the melted butter, full-fat cream, and minced garlic. Stir until well combined. This creamy base will infuse the potatoes with incredible flavor as they bake.
- Preheat Your Oven: Set your oven to 180°C / 350°F. This moderate temperature is perfect for slowly cooking the potatoes through.
- Slice the Potatoes: Peel your potatoes and then slice them very thinly, about 1/8 inch or 3 mm thick. A mandoline slicer is helpful here for uniform slices, but a sharp knife and a steady hand work just as well.
- Begin Layering: Into your chosen baking dish, start by spreading one-third of your thinly sliced potatoes. Pour over one-third of the prepared cream mixture, then sprinkle with one-third of the salt, pepper, and fresh thyme leaves (if using). Top this layer with about 3/4 cup of your grated Gruyere cheese.
- Repeat the Layers: Continue layering in the same fashion, repeating the process of adding potatoes, cream mixture, salt, pepper, and thyme for two more times. Crucially, do not add any cheese to this final potato and cream layer.
- First Bake: Cover your baking dish securely with a lid or aluminum foil. Place it in the preheated oven and bake for 1 hour and 15 minutes. The potatoes should be wonderfully tender when you pierce them with a knife; this might take up to 1 hour and 30 minutes depending on your oven and potato thickness.
-
The Golden Finish: Once the potatoes are tender, carefully remove the cover from the dish. Sprinkle the remaining grated cheese evenly over the top. Return the dish to the oven, uncovered, and bake for an additional 10 to 15 minutes, or until the cheese is beautifully golden and bubbling.
Pro Tip: Letting the potatoes rest for at least 5 minutes after they come out of the oven allows the sauce to thicken slightly and the flavors to meld beautifully.
Recipe Tips
- Uniform Slices are Key: For even cooking, ensure all your potato slices are of a similar thickness. This allows them to absorb the cream and become tender at the same rate.
- Don’t Overcrowd: While it’s tempting to pack the dish full, leave a little room for the cream to bubble up.
- Test for Tenderness: A thin-bladed knife or a skewer is your best friend for checking if the potatoes are cooked through. They should slide in with very little resistance.
- Resting is Important: Don’t skip the brief resting period after baking. It makes a noticeable difference in the final consistency.
FAQs
- Can I use a different type of potato? While starchy potatoes are recommended, all-purpose potatoes can also work, though they might not become quite as creamy. Waxy potatoes are best avoided as they tend to hold their shape and can result in a less tender dish.
- What size baking dish should I use? A standard 9×13 inch baking dish is perfect for this amount of potatoes. If your dish is deeper, you might need to slightly adjust the baking time.
- Why is the cheese not added to the top layer initially? Adding the cheese in layers during the first bake ensures it melts into the potatoes, while saving some for the top allows for a perfectly golden and bubbly crust at the end.
Serving Suggestions
Creamy Potatoes Dauphinoise is a versatile side that pairs wonderfully with a variety of main courses. It’s an absolute star alongside roasted chicken, pan-seared steak, or even a simple grilled fish. For a vegetarian feast, serve it with a hearty green salad and some crusty bread to sop up any extra creamy goodness. It also makes a wonderfully satisfying addition to a holiday meal.
Make This Recipe in Advance
While best enjoyed fresh, you can prepare components of this dish ahead of time. The potatoes can be peeled and sliced up to 24 hours in advance and kept submerged in cold water in the refrigerator to prevent browning. You can also prepare the cream mixture a day ahead. Assemble the dish just before baking for the freshest results. Once baked, leftovers can be stored in an airtight container in the refrigerator for up to 2 days and gently reheated in a low oven or microwave.
