Step‑by‑Step Instructions for Mary Berry Potato Gratin

Step 1: Preheat the Oven
Start by preheating your oven to 180°C (160°C fan) or 350°F. This ensures that your Mary Berry Potato Gratin cooks evenly and creates that lovely golden crust. As the oven warms up, it’s the perfect time to gather all your ingredients and ready your baking dish for the layers ahead.

Step 2: Prepare the Potatoes
Peel your potatoes and slice them thinly, aiming for about 3mm thickness for optimal cooking. The even slices allow for uniform layering in the gratin, ensuring that each forkful offers that comforting texture. Once sliced, set them aside in a bowl of cold water to prevent browning while you prepare the leeks.

Step 3: Sauté the Leeks
In a sauté pan, heat a splash of butter or oil over medium heat. Add the sliced leeks and sauté them for about 5-7 minutes, or until they become soft and slightly translucent. This step enhances the leeks’ natural sweetness, infusing your gratin with depth. After cooking, remove the pan from heat and set aside.

Step 4: Mix the Cream Sauce
In a mixing bowl, combine the double cream, whole milk, crushed garlic, salt, pepper, and nutmeg. Whisk until well blended; you want a smooth, creamy sauce that will envelop the layers of potatoes and leeks. This mixture forms the heart of the Mary Berry Potato Gratin, providing that rich flavor we crave.

Step 5: Assemble the Gratin
Grease your chosen baking dish with a little butter or oil to prevent sticking. Start layering by placing a layer of sliced potatoes on the bottom, followed by a layer of sautéed leeks. Repeat this process until all your ingredients are used up, finishing with a top layer of potatoes for an appealing presentation.

Step 6: Pour the Cream Mixture
Carefully pour the creamy sauce over the layered potatoes and leeks, ensuring the mixture seeps down between the layers. This step is crucial for achieving that creamy consistency throughout your Mary Berry Potato Gratin. Be generous, as it will create a luxurious texture that melds beautifully during baking.

Step 7: Add the Cheese Topping
Generously sprinkle your selected cheese (Gruyère or Cheddar) on top of the assembled gratin. This will create a wonderfully bubbling and golden crust as it bakes. Make sure to cover the whole surface, so every slice has that delightful cheesy layer that everyone loves in a gratin.

Step 8: Bake the Gratin
Cover the baking dish with foil to prevent over-browning and place it in the preheated oven. Bake for 45 minutes to allow the potatoes to become tender and the flavors to meld beautifully. After this initial baking period, remove the foil and continue baking for an additional 15-20 minutes, or until the top is golden and bubbly.

Step 9: Cool Before Serving
Once baked, take the gratin out of the oven and let it sit for a few minutes. This cooling period allows the layers to set, making it easier to slice and serve. The result will be a perfectly creamy yet firm Mary Berry Potato Gratin ready to impress at your dinner table.
