🥔 Jamie Oliver Potato And Leek Gratin Ingredients

2 ½ cups (600 ml) whole milk
1 ½ pounds (680 g) Yukon Gold potatoes, raw and sliced
2 garlic cloves, smashed
1 tablespoon unsalted butter
1 large leek, trimmed, halved lengthwise, and sliced (about 2 cups/300 g)
1 teaspoon kosher salt, divided
2 ounces (60 g) Gruyère cheese, shredded (about 1/2 cup/60 g)
1 ounce (30 g) Parmesan cheese, grated (about 1/4 cup/30 g)
½ teaspoon freshly ground black pepper

🥘 How To Make Jamie Oliver Potato And Leek Gratin

Preheat the Oven: Preheat your oven to 375°F (190°C). This will ensure the oven is ready for baking the gratin later.
Prepare the Potatoes and Garlic: In a large saucepan, boil the whole milk, sliced potatoes, and smashed garlic cloves together. Then, reduce the heat and let it simmer for about 5 minutes until the potatoes are almost soft. After this, drain the potatoes and garlic using a sieve, making sure to reserve 1/2 cup (120 ml) of the milk mixture.
Cook the Leeks: In a 10-inch (25 cm) cast-iron skillet, melt the unsalted butter over medium heat. Next, add the sliced leeks and cook for about 8 minutes, stirring occasionally until they are soft. Then, remove the skillet from the heat and place the leek mixture in a bowl.
Layer the Potatoes and Leeks: In the bottom of the same skillet or a gratin dish, place half of the sliced potatoes. Then, top with half of the cooked leek mixture. After that, sprinkle 1/4 cup (30 g) of Gruyère cheese and 1/2 teaspoon of kosher salt.
Add the Remaining Layers: Next, repeat the layering process with the remaining potatoes and leek mixture. Then, sprinkle another 1/4 cup (30 g) of Gruyère cheese and the remaining 1/2 teaspoon of kosher salt. Finally, sprinkle the grated Parmesan cheese on top and drizzle the reserved 1/2 cup (120 ml) of milk mixture over the entire dish.
Bake the Gratin: Cover the pan with foil and bake in the preheated oven at 375°F (190°C) for 25 minutes. This will allow the flavors to meld together and the cheese to melt.
Broil for a Golden Finish: After baking, remove the foil from the pan. Then, switch the oven to the broiler setting. Broil the gratin for about 5 minutes until it becomes bubbly and golden brown on top.
Finish and Serve: Remove the gratin from the oven. Then, sprinkle freshly ground black pepper over the top. After that, let the pan cool slightly. Finally, divide the gratin into 10 wedges and serve it warm.

💭 Recipe Tips

Choose Yukon Gold Potatoes: Use Yukon Gold potatoes because they have a creamy texture and stay firm when cooked, making your gratin smooth and tasty.
Slice Potatoes Evenly: Cut the potatoes into even slices so they cook evenly. If you have a mandoline slicer, use it to make thin, even slices.
Simmer Slowly: When cooking the potatoes in milk, keep the heat low and stir sometimes to stop the milk from burning and the potatoes from sticking.
Cook Leeks Until Soft: Make sure the leeks are very soft before using them. This makes their flavor better and helps them mix well with the potatoes.
Broil with Care: Watch the gratin closely when broiling so it doesn’t burn. Broil until the top is just golden brown and bubbly for a perfect finish.
