Preparing Potato and Leek Gratin
Potato and leek gratin is one of those comforting dishes that feels like a warm hug after a long day. This creamy, cheesy delight is a perfect side for any meal, and the best part is it's relatively easy to prepare! Here’s a detailed guide on how to make your own beautifully layered Potato and Leek Gratin.
Gather and prepare your ingredients
Before diving into the cooking process, it’s essential to gather all your ingredients to make the flow of cooking smooth and enjoyable. Here’s what you’ll need:
- 1 large leek, washed and thinly sliced
- 4 large potatoes, peeled and thinly sliced
- 2 cloves of garlic, minced
- 250ml double cream
- 75g grated extra mature cheddar cheese
- 1 teaspoon smoked paprika, thyme, and rosemary
- 0.5 teaspoon oregano, 1 teaspoon salt, and black pepper
Once you have everything ready, peel your potatoes and slice them as thin as possible—about 0.5cm thick. A mandolin works wonders here if you have one. The thinner the slices, the crispier your gratin will be!
Sauté the leeks and garlic
In a large pan, melt a knob of butter over medium heat. Add the sliced leeks and sauté them for about 3-4 minutes until they soften. The leeks will provide a fabulous base flavor—no one can resist that lovely oniony aroma wafting through the kitchen! After the leeks are softened, stir in the minced garlic and continue to sauté for another minute.
Create the creamy sauce
Next, you’ll introduce the creamy goodness! Pour in the double cream, followed by your herbs and spices. I recommend using homemade vegetable stock as a substitute for wine if you want to keep it alcohol-free. Allow the mixture to simmer for about 3-4 minutes until it thickens. Stir in about three-quarters of your grated cheese to make it irresistibly cheesy. Once everything is combined, remove the pan from the heat.
Layer the potatoes and sauce beautifully
This is where your gratin starts to take shape! In a greased baking dish, spoon a little of the creamy leek mixture at the bottom to prevent sticking. Now, layer your sliced potatoes upright around the dish. You can arrange them tightly for that spectacular visual effect while maximizing crispiness! Once you’ve placed all the potatoes, pour the rest of your creamy sauce over them, ensuring it seeps into the cracks.
Bake to perfection and achieve that golden top
Cover your baking dish with foil and pop it into a preheated oven at 190°C (375°F). Bake for 40 minutes, then remove the foil and sprinkle the remaining cheese on top. Bake it uncovered for an additional 20 minutes until it’s bubbling and golden. The end result? A gorgeous Potato and Leek Gratin that will have everyone asking for seconds!
Whether enjoyed on its own or as a side dish, this gratin is sure to impress. Plus, check out our guide on how to pair wines with cheesy dishes—it adds a fantastic twist to your dining experience! Enjoy!

Cooking tips and notes for Potato and Leek Gratin
Ensuring crispy potatoes
For the perfectly crispy potatoes in your Potato and Leek Gratin, slicing them thinly is crucial; aim for around 0.5 cm. Using a mandolin can help achieve uniformity, ensuring even cooking throughout. Stacking the potatoes upright allows for maximum exposure to heat, which enhances that delightful crunch. A sprinkle of extra cheese on top before baking not only adds flavor but encourages a beautifully golden crust.
Storing and reheating leftovers
If you’re fortunate enough to have leftovers, you can store them in an airtight container in the fridge for up to 3 days. To reheat, cover the dish with foil to prevent the top from burning, and bake at 180°C (350°F) for about 30 minutes or until warmed through. This method helps retain the creaminess, making each bite just as delicious as when freshly baked. For more tips on food storage and reheating, check out FoodSafety.gov.
