Ingredients for Gratin Dauphinois (Creamy Potato and Cheese Casserole)

1 1/2 cup heavy cream
1/2 teaspoon kosher salt
1/2 teaspoon black pepper
2 cloves garlic, peeled and smashed
3 sprigs fresh thyme, plus more for serving
2 tablespoons unsalted butter
3 cloves shallots, diced
2 pounds red potatoes, sliced into 1/8 inch slices
4 ounces Gruyère cheese, grated

Preparing the Cream Mixture

Infusing the Cream

To start, combine the heavy cream with kosher salt, black pepper, smashed garlic, and fresh thyme in a saucepan. Place it over medium heat and allow it to simmer gently. Once it starts bubbling just a bit, remove it from the heat and let it cool slightly. This step is key, as it allows the cream to absorb all the wonderful flavors from the garlic and thyme—trust me, it makes a world of difference in your Gratin Dauphinois!

Cooking the Potatoes

Sautéing Shallots

Heat up a large oven-safe skillet over medium heat. Add the unsalted butter, letting it melt and foam up. Toss in the diced shallots and sauté them until they’re tender and fragrant, which should take about 3 to 4 minutes. This fragrant base adds another layer of flavor to your creamy potato and cheese casserole.

Layering the Potatoes

Now, it’s time to layer! Start arranging the sliced red potatoes in the skillet, overlapping them slightly. This ensures even cooking and an aesthetically pleasing presentation. Take your time here; those layers are what make Gratin Dauphinois shine. Once you’re done, it’s a feast for the eyes already!

Combining and Baking

Adding Cream Mixture

After layering, remove the garlic and thyme sprigs from the cream mixture. Pour this luscious cream evenly over the potatoes, making sure every slice gets its fair share of that creamy goodness. Next, cover the skillet with foil—this keeps the moisture in, creating perfectly tender potatoes as they bake.

Baking for Tenderness

Place your skillet in a preheated oven set at 325°F. Allow it to bake for about 75 to 85 minutes, or until the potatoes are fork-tender. The anticipation builds! Your kitchen will fill with a delightful aroma, hinting at the deliciousness awaiting you.

Finishing Touch

Broiling for Crispiness

Once the baking time is up, remove the foil and sprinkle the grated Gruyère cheese generously over the top. Now, it’s your moment to shine! Place the skillet under the broiler for a few minutes until the cheese turns a beautiful golden brown. Keep a close eye on it, as broiling can go from perfect to burned in mere seconds. This last touch creates that crispy topping everyone loves!

Serving Suggestions

Gratin Dauphinois is incredibly versatile! You can serve it alongside roasted meats for a hearty meal or pair it with a fresh salad for a lighter option. It also works beautifully as a side dish at holiday gatherings, complementing festive fare with ease. Consider adding a sprinkle of extra thyme for garnish; it makes for a lovely presentation.

Tips for Success

When choosing potatoes, go for red or Yukon gold. They hold their shape nicely and add creaminess to the dish.
Ensure your potato slices are uniform for even cooking—aim for about 1/8 inch thick.
For the best creamy texture, avoid rushing through the layering and allow the cream to soak into the potatoes.

Variations

Feel free to make this dish your own! Consider adding a combination of cheeses for a new flavor profile. Cheddar or fontina can introduce a fun twist. You might also include vegetables like spinach or mushrooms for added nutrition and taste. A pinch of nutmeg can also elevate the flavor, turning this classic into something uniquely yours.

Storage Tips

If you have leftovers—though they are rare—store any Gratin Dauphinois in an airtight container in the fridge. Reheat in the oven for the best results. Simply cover it with foil to prevent drying out, and reheat until everything is warmed through.

Pairing Ideas

To complement your Gratin Dauphinois, consider pairing it with a full-bodied white wine, like Chardonnay, which balances the richness of the dish. Green salads or roasted vegetables make fantastic sides, adding freshness that brightens up the meal.
