- 50 g of butter

Instructions to Make Jamie Oliver Leek and Potato Gratin
Follow these steps to make this recipe:
Step 1: Preheat the oven and prepare the baking dish
First, preheat your oven to 180°C/160°C fan/gas 4. Then, grease a 25 x 30 cm baking dish with some butter or cooking spray. Set it aside for later.
Step 2: Cook the potatoes and leeks
Next, bring a large pot of salted water to a boil. Add the sliced potatoes and cook them for about 15 minutes, or until they are tender but not falling apart. Drain them and set them aside. In the same pot, add some more water and bring it to a boil. Add the sliced leeks and cook them for about 10 minutes, or until they are soft and bright green. Drain them and set them aside as well.
Step 3: Make the cheese sauce
Now, it’s time to make the cheese sauce. In a medium saucepan over low-medium heat, melt the butter. Add the garlic and cook for a few minutes, stirring occasionally, until fragrant. Then, add the flour and whisk well to form a smooth paste. Gradually add the milk, whisking constantly, until you have a smooth and creamy sauce. Bring it to a boil, then lower the heat and simmer for about 10 minutes, stirring occasionally, until thickened. Season with salt, pepper, and nutmeg, if using. Then, stir in half of the grated cheese and mix well.
Step 4: Assemble the gratin
Finally, it’s time to assemble the gratin. In the prepared baking dish, layer half of the potatoes, overlapping them slightly. Sprinkle some salt and pepper over them. Then, spread half of the leeks over the potatoes. Pour half of the cheese sauce over the leeks, spreading it evenly. Repeat with the remaining potatoes, leeks, and cheese sauce. Sprinkle the rest of the grated cheese on top.
Step 5: Bake and serve
Bake the gratin in the preheated oven for about 25 minutes, or until golden and bubbly. Let it rest for 10 minutes before serving. Garnish with some chopped parsley, if desired. Enjoy your leek and potato gratin by Jamie Oliver with some salad, bread, or meat of your choice.

How do I clean the leeks and slice the potatoes for this recipe?
To clean the leeks, slice them down to the root, then rotate them and slice them again, to make 4 even sections. Rinse them under cold water to remove any dirt or grit. To slice the potatoes, use a mandoline or a food processor to cut them into thin and even slices, about 0.5 cm thick. Rinse them in cold water to remove some of the starch, which can make the gratin too gluey.
Can I add other vegetables to this gratin recipe?
Absolutely! While the classic leek and potato pairing is delightful, you can add other vegetables such as sliced mushrooms, spinach, or diced bell peppers for extra flavor and nutrition.
