## Instructions:

### Part 1: Making the Crust

The crust is the foundation of any good quiche. This recipe uses a classic pâte brisée, a shortcrust pastry known for its buttery and flaky texture. You can make the crust by hand or using a food processor. A food processor makes the process faster, but making it by hand gives you more control over the dough’s texture.

**Method 1: Using a Food Processor**

1. **Combine dry ingredients:** In the food processor, combine the flour and salt. Pulse a few times to mix.
2. **Add butter:** Add the cold, cubed butter to the food processor. Pulse until the mixture resembles coarse crumbs. This usually takes about 10-15 short pulses. Be careful not to over-process, as this will develop the gluten in the flour and result in a tough crust.
3. **Add water:** With the food processor running on low, slowly add the ice water, one tablespoon at a time, until the dough just comes together. Don’t add all the water at once; you may not need it all. The dough should be moist but not sticky.
4. **Shape and chill:** Turn the dough out onto a lightly floured surface. Gently gather it into a disc. Wrap the disc tightly in plastic wrap and chill in the refrigerator for at least 30 minutes, or up to 2 hours. This allows the gluten to relax, resulting in a more tender crust.

**Method 2: Making the Crust by Hand**

1. **Combine dry ingredients:** In a large bowl, whisk together the flour and salt.
2. **Cut in the butter:** Add the cold, cubed butter to the bowl. Using a pastry blender or your fingertips, cut the butter into the flour until the mixture resembles coarse crumbs. The butter should be in small pieces, about the size of peas.
3. **Add water:** Gradually add the ice water, one tablespoon at a time, mixing with a fork until the dough just comes together. Be careful not to overwork the dough. It should be moist but not sticky.
4. **Shape and chill:** Turn the dough out onto a lightly floured surface. Gently gather it into a disc. Wrap the disc tightly in plastic wrap and chill in the refrigerator for at least 30 minutes, or up to 2 hours.

### Part 2: Preparing the Leek Filling

The leek filling is the heart of this quiche. Sautéing the leeks slowly brings out their natural sweetness and softens their texture, creating a melt-in-your-mouth sensation.

1. **Prepare the leeks:** Thoroughly wash the leeks to remove any dirt or sand. Slice them thinly, using only the white and light green parts. Leeks can trap a lot of dirt between their layers, so be sure to wash them well.
2. **Sauté the leeks:** Heat the olive oil in a large skillet over medium heat. Add the sliced leeks and minced garlic. Sauté until the leeks are soft and translucent, about 10-15 minutes. Stir frequently to prevent them from browning. If the leeks start to brown too quickly, reduce the heat to low.
3. **Cool slightly:** Remove the skillet from the heat and let the leeks cool slightly while you prepare the custard.

### Part 3: Blind Baking the Crust

Blind baking is a crucial step in making quiche. It involves baking the crust before adding the filling to prevent it from becoming soggy. This ensures a crisp and flaky crust that can hold the creamy filling without collapsing.

1. **Preheat oven:** Preheat your oven to 375°F (190°C).
2. **Roll out the dough:** On a lightly floured surface, roll out the chilled dough into a 12-inch circle. The dough should be large enough to fit into your 9-inch pie dish with some overhang.
3. **Transfer to pie dish:** Carefully transfer the dough to the pie dish. Gently press the dough into the bottom and sides of the dish. Trim any excess dough, leaving about a 1/2-inch overhang. Crimp the edges of the crust to create a decorative border.
4. **Dock the crust:** Use a fork to prick the bottom of the crust all over. This helps to prevent the crust from puffing up during baking.
5. **Line with parchment paper:** Line the crust with parchment paper, making sure the paper covers the entire surface of the dough and extends over the edges of the dish. This will make it easier to remove the pie weights or beans after baking.
6. **Add pie weights or beans:** Fill the parchment paper with pie weights or dried beans. This will weigh down the crust and prevent it from shrinking or puffing up during baking.
7. **Bake:** Bake the crust for 15 minutes. Remove the parchment paper and pie weights or beans. Return the crust to the oven and bake for another 5-10 minutes, or until the crust is lightly golden brown. Watch carefully to prevent the edges from burning. If the edges start to brown too quickly, cover them with aluminum foil.
8. **Cool slightly:** Remove the crust from the oven and let it cool slightly while you prepare the custard filling.

### Part 4: Making the Custard Filling

The custard filling is what makes the quiche so rich and decadent. The combination of cream, milk, and eggs creates a smooth and velvety texture that perfectly complements the sweetness of the leeks and the sharpness of the cheese.

1. **Whisk ingredients:** In a large bowl, whisk together the heavy cream, milk, eggs, salt, pepper, and nutmeg (if using). Whisk until the mixture is smooth and well combined. Be careful not to over-whisk, as this can incorporate too much air into the custard and cause it to puff up and then deflate during baking.
2. **Add cheese:** Stir in the grated Gruyere cheese (or a blend of Gruyere and Parmesan) until it is evenly distributed throughout the custard.

### Part 5: Assembling and Baking the Quiche

Now that you have all the components ready, it’s time to assemble the quiche and bake it to perfection.

1. **Arrange leeks in crust:** Spread the sautéed leeks evenly over the bottom of the blind-baked crust.
2. **Pour custard filling:** Gently pour the custard filling over the leeks. Make sure the filling is evenly distributed throughout the crust. If necessary, use a spoon to gently move the leeks around so that they are submerged in the custard.
3. **Bake:** Bake the quiche in the preheated oven for 30-40 minutes, or until the custard is set and lightly golden brown. The center of the quiche should be just slightly wobbly when you gently shake the pie dish. If the crust starts to brown too quickly, cover the edges with aluminum foil.
4. **Cool slightly:** Remove the quiche from the oven and let it cool slightly on a wire rack for at least 15 minutes before slicing and serving. This allows the custard to set completely and prevents it from collapsing when you cut into it.

## Serving Suggestions:

The leek and cheese quiche is delicious served warm or at room temperature. It can be enjoyed on its own or paired with a variety of sides.

* **Salad:** A simple green salad with a light vinaigrette is a perfect accompaniment to the rich quiche.
* **Soup:** A creamy tomato soup or a light vegetable soup complements the quiche beautifully.
* **Fruit:** A side of fresh fruit adds a refreshing touch to the meal.
* **Bread:** A crusty baguette or some warm rolls are perfect for soaking up any leftover custard.

## Tips and Variations:

* **Cheese:** Feel free to experiment with different types of cheese. Sharp cheddar, Swiss, or even goat cheese would be delicious in this quiche.
* **Vegetables:** Add other vegetables to the filling, such as mushrooms, spinach, or asparagus.
* **Meat:** For a heartier quiche, add cooked bacon, ham, or sausage to the filling.
* **Crustless Quiche:** For a gluten-free option, omit the crust and bake the filling in a greased pie dish.
* **Make Ahead:** The crust can be made ahead of time and stored in the refrigerator for up to 2 days or in the freezer for up to 1 month. The leek filling can also be made ahead of time and stored in the refrigerator for up to 2 days. Assemble the quiche just before baking.
* **Freezing:** Baked quiche can be frozen for up to 2 months. Wrap it tightly in plastic wrap and then in aluminum foil. Thaw in the refrigerator overnight before reheating.
