Mary Berry Leek And Potato Gratin Recipe

Ingredients Needed

To prepare a delightful Mary Berry’s Leek and Potato Gratin, you’ll need a variety of ingredients that come together in a deliciously creamy and comforting dish. Each ingredient plays an important role in building the layers of flavor, texture, and richness that make this recipe so special. Here’s a breakdown of what you’ll need:

• Potatoes (about 900g or 2 pounds): The heart of the gratin, potatoes provide the necessary starch and structure. It’s essential to choose waxy potatoes like Charlotte or Yukon Gold, which hold their shape well during cooking and lend a creamy texture when baked.

• Leeks (2 medium-sized): Leeks offer a sweet, mild onion flavor that contrasts beautifully with the richness of the cream. Slice them thinly to ensure they cook evenly and blend smoothly into the gratin. You’ll need to wash them thoroughly to remove any dirt hidden between the layers.

• Butter (around 50g or 3.5 tablespoons): This gives the gratin a rich, indulgent base while also helping to sauté the leeks to softness before combining with the potatoes. Butter contributes both flavor and moisture, elevating the dish’s comforting qualities.

• Double Cream (300ml or about 1 ¼ cups): This is where the magic happens. Double cream creates a velvety richness that binds the potatoes and leeks together. It’s this creamy element that makes the gratin a luxurious side dish.

• Milk (150ml or ½ cup): The addition of milk thins the double cream slightly while ensuring the gratin isn’t too heavy. It helps balance the richness of the cream while still keeping the dish smooth and luscious.

• Garlic (2 cloves, minced): Garlic adds a savory depth to the gratin, bringing out the sweetness of the leeks and the earthiness of the potatoes. It’s a subtle but essential addition that enhances the overall flavor profile.

• Cheese (100g or 1 cup of grated cheese, like Gruyère or cheddar): Cheese gives the gratin its golden, bubbling top and adds another layer of richness and flavor. Gruyère melts beautifully, forming a perfect crust, while cheddar adds a sharp, savory note that complements the creamy components.

• Fresh Thyme (a few sprigs): Thyme is a classic herb in French-style dishes, offering a fresh, slightly earthy flavor that works well with both potatoes and leeks. It complements the other ingredients without overpowering them.

• Salt and Pepper: These staples season the dish and help bring out the natural flavors of the leeks and potatoes. Make sure to season generously but taste along the way to avoid overdoing it.

These ingredients come together to create a decadent, layered dish that’s sure to be a crowd-pleaser at any gathering. Now, let’s move on to the equipment needed to bring this dish to life.

Equipment Needed

To prepare Mary Berry’s Leek and Potato Gratin, you’ll need the following equipment to make the process as seamless as possible:

• Sharp Knife: For slicing the potatoes and leeks with precision. A sharp knife will ensure even slices, which is important for consistent cooking and texture in your gratin.

• Chopping Board: A sturdy surface to chop your vegetables safely and easily. It’s essential for keeping everything neat and avoiding any accidents.

• Saucepan: A medium-sized saucepan is essential for sautéing the leeks and garlic, as well as heating the milk and cream mixture. You want a pot with enough room to stir the ingredients without spilling over.

• Gratin Dish (approximately 2L capacity): This is where the gratin will bake. Ideally, you should use a shallow, oven-safe dish, such as a ceramic or glass gratin dish. The shallow sides allow for even cooking and help the gratin crisp up beautifully on top.

• Grater: You’ll need this to grate your cheese. While store-bought grated cheese can work in a pinch, grating it fresh ensures better texture and flavor. A box grater or a fine grater works best for this recipe.

• Peeler: To peel the potatoes, a simple vegetable peeler will do. This is an important step to ensure that you’re using clean, smooth potatoes for the gratin, without any tough or bitter skin.

• Wooden Spoon or Spatula: A wooden spoon or spatula is useful for stirring the sautéed leeks and garlic and for mixing the creamy sauce, ensuring everything is evenly combined.

• Oven Mitts: As the gratin will be baked in the oven at a high temperature, oven mitts are crucial to protect your hands from burns when removing the hot dish from the oven.

Having the right equipment ensures that you can make this dish with ease, letting you focus on the fun part: assembling and cooking the gratin.

How To Make Mary Berry’s Leek And Potato Gratin

Now that you have all your ingredients and equipment ready, it’s time to dive into the step-by-step process of making this luxurious leek and potato gratin. Follow these detailed instructions for a perfectly cooked dish:

1. Prepare the Ingredients:

   Start by peeling the potatoes and slicing them into thin, even rounds (about 3mm thick). This ensures that they cook uniformly and absorb the creamy sauce. Clean and trim the leeks, removing the tough green tops, and slice the remaining white and light green parts thinly.

2. Preheat the Oven:

   Preheat your oven to 180°C (350°F). Grease your gratin dish with a little butter to ensure the gratin doesn’t stick during baking.

3. Cook the Leeks:

   In a medium-sized saucepan, melt the butter over medium heat. Add the sliced leeks and cook them gently for about 5-7 minutes, until softened but not browned. Add the minced garlic in the last minute and cook until fragrant, ensuring the garlic doesn’t burn.

4. Prepare the Cream Sauce:

   In a separate saucepan, combine the milk and double cream, and heat gently over low heat. You don’t need to bring it to a boil, just warm it up enough to combine with the leeks later.

5. Assemble the Gratin:

   Layer the sliced potatoes at the bottom of the greased gratin dish, slightly overlapping them. Add a layer of the cooked leeks and garlic on top.

   Sprinkle with a little salt, pepper, and fresh thyme. Repeat the layers, making sure to season each layer as you go. Pour the warm cream and milk mixture over the top, ensuring it evenly coats the potatoes and leeks.

6. Top with Cheese:

   Finally, sprinkle the grated cheese evenly over the top of the gratin. The cheese will melt and form a delicious, golden crust as the dish bakes.

7. Bake:

   Place the gratin in the oven and bake for about 45 minutes to an hour, or until the potatoes are tender when pierced with a fork and the top is golden and bubbly. If the top is browning too quickly, you can cover it with foil for the first 30 minutes and then uncover it to allow the top to crisp up.

8. Serve and Enjoy:

   Once the gratin is done, remove it from the oven and let it sit for a few minutes before serving. This gives the layers a chance to set, making it easier to cut clean portions.

Expert Tips

1. Uniform Slicing: For the best texture, it’s important to slice the potatoes and leeks as evenly as possible. This ensures even cooking and prevents some pieces from being overcooked while others are undercooked.

2. Pre-cook the Leeks: While leeks can be added raw, sautéing them first enhances their sweetness and helps release moisture, ensuring they don’t end up too soggy in the gratin.

3. Choosing the Right Potatoes: For a gratin, you want potatoes that hold their shape during cooking but also absorb the creamy sauce. Waxy potatoes like Charlotte, Yukon Gold, or even new potatoes are ideal choices.

4. Layering the Ingredients: Don’t rush through layering the ingredients. Take the time to evenly distribute the leeks, potatoes, and seasoning to ensure that each bite has the perfect balance of flavor and texture.

5. Add Extra Flavor: For extra depth, you can add a pinch of nutmeg or a drizzle of white wine to the cream sauce. Nutmeg complements creamy dishes beautifully, while wine can introduce an extra layer of sophistication.

6. Resting Time: After baking, let the gratin rest for 5-10 minutes before serving. This allows the layers to firm up and makes serving much easier.

Mary Berry’s Leek and Potato Gratin is a comforting, rich dish that’s perfect for a cozy family meal or as a side for special occasions. With layers of tender potatoes, sweet leeks, and a creamy, cheesy sauce, this gratin offers an irresistible combination of textures and flavors.

Easy Recipe Variations For Mary Berry’s Leek And Potato Gratin

Mary Berry’s leek and potato gratin is a quintessential comfort food, rich and creamy with a delicate blend of flavors. However, the beauty of this dish lies in its versatility, allowing for easy adjustments and variations depending on your taste preferences or dietary needs. Here are a few creative and easy variations to give the classic gratin a fresh twist:

1. Cheese Variations:
   The traditional recipe often uses cheese like Gruyère or cheddar. For a different flavor profile, you could experiment with other types of cheese. A sharp blue cheese, like Roquefort or Gorgonzola, will add a distinct tangy richness to the gratin, while a mild mozzarella will keep the dish gooey and creamy. For a dairy-free version, consider using plant-based cheeses made from nuts or soy, which can melt beautifully and still provide that rich creaminess.

2. Herb and Spice Additions:
   Mary Berry’s recipe is simple, focusing on the natural flavors of the leeks and potatoes, but you can elevate it with the addition of fresh or dried herbs. Thyme and rosemary are classic choices that complement the dish beautifully. For a more Mediterranean twist, consider adding some fresh oregano and basil. If you like a touch of heat, a pinch of chili flakes or a small dash of smoked paprika can introduce a gentle warmth to balance the creaminess.

3. Add Protein:
   To turn this gratin into a more substantial meal, you could add protein. Smoked salmon or crispy bacon bits make excellent additions and pair wonderfully with the mild flavors of the leeks and potatoes. For a vegetarian protein, sautéed mushrooms or a handful of cooked lentils could bring some heartiness to the dish, while still keeping it satisfying and comforting.

4. Vegetarian/Plant-Based Alternatives:
   For those following a vegetarian or vegan diet, swapping the dairy for plant-based milk and cheese is an easy and delicious alternative. Coconut milk or cashew cream can add a luscious, creamy texture, while nutritional yeast can provide a cheesy flavor without any animal products. You can also swap the butter for a plant-based margarine or olive oil to keep the dish completely vegan.

5. Addition of Other Vegetables:
   Leeks and potatoes are the stars of this gratin, but you can incorporate other vegetables to add variety and extra nutrients. Sliced carrots or parsnips can bring in an earthy sweetness, while spinach or kale can add a nice burst of color and a slightly bitter contrast to the creamy sauce. A few peas or even sweetcorn can bring a pop of sweetness and texture, making the dish more vibrant and diverse.

Best Practices To Store Leftovers

Leek and potato gratin, like many casseroles, can make for an amazing leftover dish, and knowing how to store it properly ensures it stays fresh and delicious. Here are some best practices to follow:

1. Cooling and Storage:
   Before storing any leftovers, it’s important to let the gratin cool to room temperature. This helps prevent condensation from forming inside the container, which can make the dish soggy. Once cooled, transfer the gratin to an airtight container. If you’ve made a large batch, portioning the leftovers into smaller containers can make it easier to reheat individual servings.

2. Refrigeration:
   Leek and potato gratin can be stored in the refrigerator for up to 3 to 4 days. Ensure that the container is well-sealed to maintain freshness and prevent the gratin from absorbing any odors from other foods in the fridge.

3. Freezing:
   If you’re planning to keep leftovers for longer, leek and potato gratin freezes very well. To freeze, allow it to cool completely before wrapping it tightly in plastic wrap and then aluminum foil or placing it in a freezer-safe container. Frozen gratin can last for up to 2 months. When you’re ready to enjoy it, thaw the gratin in the refrigerator overnight before reheating.

4. Reheating:
   Reheating leek and potato gratin can be a bit tricky if you’re trying to keep the dish creamy and not dry it out. The best way to reheat it is in the oven. Preheat your oven to 180°C (350°F), cover the gratin with foil, and heat for 20-25 minutes. For a golden, crispy top, remove the foil during the last 5 minutes. If you’re reheating just a small portion, the microwave works too, but be sure to cover the dish with a damp paper towel to keep the moisture in.

5. Avoid Overheating:
   Overheating can cause the potatoes to become mushy and the creamy sauce to separate. It’s best to reheat at a moderate temperature to preserve the integrity of the dish.

What Goes Well With Leek And Potato Gratin

Leek and potato gratin is a rich and creamy dish that can be enjoyed on its own or paired with a variety of sides and mains. Here are some ideas for what to serve alongside your gratin to create a well-rounded meal:

1. Roast Meats:
   Leek and potato gratin is an excellent accompaniment to roasted meats, such as roast chicken, beef, or lamb. The richness of the gratin complements the savory flavors of the meat beautifully. For a classic pairing, serve it with roast chicken, where the slight tanginess of the gratin will cut through the richness of the roasted bird.

2. Green Vegetables:
   Since the gratin is a hearty and creamy dish, balancing it with something light and fresh is a great way to enhance the meal. Steamed or sautéed green vegetables like broccoli, spinach, green beans, or asparagus work wonderfully. The freshness and slight bitterness of the greens provide a contrast to the indulgence of the gratin, making for a more harmonious plate.

3. Salads:
   A crisp, refreshing salad can serve as a perfect contrast to the warm, creamy gratin. A simple green salad with a light vinaigrette can provide the necessary acidity to balance the richness of the gratin. Try arugula with a balsamic vinaigrette or a citrusy salad with mixed greens, radishes, and a zesty lemon dressing.

4. Grilled Fish:
   Lightly grilled fish like salmon or trout, with its delicate flavor and flaky texture, pairs beautifully with the creamy gratin. The subtlety of the fish won’t overpower the gratin, making for a well-balanced meal. You can add a touch of lemon to both the fish and the gratin to bring out the flavors even more.

5. Crusty Bread:
   For a more indulgent option, a warm, crusty loaf of bread can be the perfect vehicle for soaking up the creamy sauce of the gratin. A rustic sourdough or a French baguette can add texture and flavor, making it an ideal accompaniment for sopping up every last bit of the gratin.
