Preparation Phase & Tools to Use

Before diving into the cooking process, it’s important to set up your kitchen for success. Start by gathering all your ingredients and tools. You’ll need a sharp knife or mandoline for slicing the potatoes, a large mixing bowl, a saucepan for heating the cream, and a baking dish to assemble the gratin. A whisk can be handy if you need to mix the heavy cream with garlic and seasonings efficiently. Don’t forget to have measuring cups and spoons ready for accurate ingredient measurements. Giving your workspace a tidyup and placing all your tools at arm’s reach will streamline the cooking process and keep you organized.

Ingredients

2 ½ pounds Yukon Gold potatoes
1 ½ cups Gruyère cheese, freshly grated
¾ cup Parmesan cheese, freshly grated
2 cups heavy cream
3 cloves garlic, smashed
2 tablespoons butter, for greasing and topping
1 teaspoon fresh thyme leaves
1 ½ teaspoons salt
½ teaspoon black pepper

Instructions

Step 1: Preheat and Prepare

Start by preheating your oven to 375°F (190°C). This ensures that your gratin bakes evenly and achieves that desired golden top. While it’s heating up, prepare your potatoes. Peel them and slice them into 1/8-inch rounds, using either a sharp knife or a mandoline for precise, even cuts. To prevent them from browning while you work, place the sliced potatoes in a bowl of cold water.

Step 2: Infuse the Cream

Next, it’s time to infuse the heavy cream with flavor. In a saucepan over medium heat, combine the heavy cream, smashed garlic cloves, salt, and pepper. Allow the cream to gently simmer for about 5 to 7 minutes; this will infuse it with the aromatic essence of garlic. Once done, remove the garlic cloves. Consider keeping the cream warm until you layer it in the gratin for an added depth of warmth.

Step 3: Layer the Ingredients

Now, grease your baking dish generously with butter to prevent sticking and add flavor. Begin the layering process by placing a layer of potato slices at the bottom of the dish. Sprinkle a handful of the grated Gruyère cheese over the potatoes, followed by a light dusting of Parmesan cheese, and then a few ladles of the warm, infused cream. Repeat this process until all ingredients are used, ensuring the final layer has a generous topping of cheese and a few dots of butter for that irresistible crispiness.

Step 4: Bake

Cover the dish with foil and place it in the preheated oven. Bake for 35 to 40 minutes, allowing the potatoes to absorb the flavors and soften. After this initial baking, carefully remove the foil to allow the top to brown beautifully. Bake uncovered for an additional 20 to 25 minutes, or until the top is golden brown and bubbling, showcasing that cheesy, crispy texture.

Step 5: Rest and Serve

Once out of the oven, let your potato gratin sit for 10 to 15 minutes before serving. This resting period allows the dish to set, making it easier to slice and serve. Just before serving, garnish the top with fresh thyme leaves for an aromatic finish.

Variations

Protein: Add cooked crumbled bacon or diced ham for a heartier dish packed with flavor.
Vegetables: Incorporate sautéed spinach or caramelized onions in between the layers for extra nutrition and taste.
Spices: For a twist, try adding a pinch of nutmeg to the cream mixture or infuse the cream with herbs like rosemary for a unique flavor profile.

Cooking Notes

For best results, always use fresh herbs and high-quality cheeses, as they greatly enhance the flavors.
If you prefer a slightly thicker gratin, consider adding an extra layer of cheese on the top before the final bake.

Serving Suggestions

Pair this gratin with a crisp salad for a complete meal.
It serves beautifully alongside roasted meats or as part of a vegetarian feast.

Tips

Make sure to slice the potatoes evenly for uniform cooking — a mandoline gives the best results.
Don’t skip the resting time after baking; it makes serving neater and enhances the flavor.
