You can use a good-quality refrigerated shortcrust pastry for convenience or prepare your favorite homemade pastry dough if you prefer.
For the Savory Filling
| Ingredient | Amount |
| Unsalted butter | 1 tablespoon |
| Extra-virgin olive oil | 1 tablespoon |
| Large leeks, washed and thinly sliced | 2 |
| Cooked chicken breast, diced | 2 cups |
| Garlic, finely minced | 1 clove |
| Gruyère or sharp cheddar, grated | 1½ cups |
For the Egg Custard
| Ingredient | Amount |
| Large eggs | 4 |
| Heavy whipping cream | 1 cup |
| Whole milk | ½ cup |
| Kosher salt | ½ teaspoon |
| Freshly ground black pepper | ¼ teaspoon |
| Ground nutmeg | Pinch |
Step-by-Step Instructions
1. Preheat the Oven and Prepare the Crust
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch deep-dish tart pan or springform pan with butter.
Unroll the pastry dough and gently press it into the bottom and sides of the pan. Trim any excess pastry around the edges if necessary.
Prick the bottom lightly with a fork. Place the prepared crust in the refrigerator and chill for approximately 15 minutes.
2. Blind Bake the Pastry
Line the chilled pastry with parchment paper and fill it with ceramic pie weights or dried baking beans.
Bake for 15 minutes. Carefully remove the parchment paper and weights, then return the crust to the oven for another 5 minutes, or until the pastry looks lightly golden and partially cooked.
Remove from the oven and set aside while you prepare the filling.
3. Sauté the Leeks
While the crust is baking, heat the butter and olive oil in a large skillet over medium heat.
Add the sliced leeks and cook for approximately 6–8 minutes, stirring occasionally, until they become soft and tender.
Add the minced garlic and cook for another 30–60 seconds, just until fragrant.
Avoid browning the leeks too aggressively. Their delicate, slightly sweet flavor is one of the highlights of this quiche.
4. Add the Chicken
Add the diced cooked chicken to the skillet with the softened leeks.
Stir everything together and cook for approximately 2–3 minutes, just long enough to warm the chicken and allow the flavors to combine.
Remove the skillet from the heat.
5. Prepare the Custard
In a large mixing bowl, whisk together the eggs, heavy cream, whole milk, salt, black pepper, and a small pinch of nutmeg.
Whisk until the mixture is smooth and evenly combined.
Do not over-whip the eggs. A gentle whisking is enough to create a smooth custard without incorporating too much air.
6. Assemble the Quiche
Spread the chicken and leek mixture evenly over the partially baked pastry crust.
Sprinkle approximately half of the grated Gruyère or cheddar over the filling.
Slowly pour the egg custard over the chicken, leeks, and cheese.
Finish with the remaining grated cheese, spreading it evenly across the surface.
7. Bake
Carefully transfer the quiche to the preheated oven.
Bake at 375°F (190°C) for approximately 30–35 minutes, or until the center is set but still has a very slight jiggle and the top is beautifully golden brown.
If the pastry edges begin browning too quickly, loosely cover them with aluminum foil while the center finishes cooking.
8. Rest Before Slicing
Remove the quiche from the oven and place it on a cooling rack.
Allow it to rest for 10–15 minutes before slicing.
This resting time allows the custard to finish setting, making the quiche easier to cut into clean, attractive slices.
Best Tips for a Perfect Chicken and Leek Quiche
Make sure the leeks are thoroughly washed before cooking. Dirt can become trapped between the layers, so separate the slices and rinse them carefully under cool running water.
Avoid adding overly wet ingredients to the filling. Excess moisture can prevent the custard from setting properly and may create a soggy pastry crust.
Using cooked chicken makes this recipe particularly convenient. Leftover roasted or baked chicken works beautifully, provided it is cut into small, evenly sized pieces.
For the best texture, allow the quiche to rest after baking rather than cutting into it immediately. The custard becomes firmer as it cools slightly.
Best Ingredient Options
Gruyère provides a nutty, savory flavor and melts beautifully. Sharp cheddar is an excellent alternative when you want a stronger, more familiar cheesy taste.
For the chicken, cooked chicken breast provides a lean and firm texture, while cooked chicken thighs can create a richer and juicier filling.
You can also use half-and-half instead of the combination of heavy cream and milk for a slightly lighter custard while maintaining a creamy texture.
Recipe Variations
For a vegetable-rich version, add sautéed mushrooms, spinach, or finely diced bell peppers to the filling. Make sure vegetables are cooked and excess moisture is removed before adding them to the crust.
For a more herb-forward quiche, add fresh thyme, parsley, chives, or a small amount of rosemary to the chicken and leek mixture.
For extra cheesiness, combine two varieties such as Gruyère and cheddar. A small amount of Parmesan can also be sprinkled over the top before baking for an especially flavorful golden crust.
What to Serve With Chicken and Leek Quiche
Serve warm slices with a crisp green salad dressed with a light vinaigrette. The freshness and acidity of the salad balance the creamy richness of the quiche.
For brunch, pair it with fresh fruit, roasted potatoes, or a simple tomato and cucumber salad.
For dinner, steamed green vegetables such as broccoli, green beans, or asparagus make excellent accompaniments.
Make-Ahead Instructions
The quiche can be prepared several hours in advance and refrigerated before serving. If preparing ahead, allow it to cool completely before covering and refrigerating.
You can also prepare the leek and chicken filling ahead of time. Store it in an airtight container in the refrigerator and assemble the quiche when ready to bake.
For entertaining, baking the quiche earlier in the day can make serving much easier because it can be enjoyed warm or at room temperature.
Storage
Allow leftover quiche to cool completely before transferring it to an airtight container or covering it tightly with plastic wrap.
Store it in the refrigerator for up to 3–4 days.
Individual slices are convenient for quick lunches and can be reheated as needed.
Reheating
For the best texture, reheat individual slices in a 350°F (175°C) oven for approximately 10–15 minutes, or until heated through.
You can also use an air fryer at approximately 325°F (165°C) for several minutes.
Microwaving is possible for convenience, but the pastry crust will generally become softer.
Freezing
Chicken and leek quiche can be frozen, although the custard texture may change slightly after thawing.
For best results, allow the baked quiche to cool completely, then wrap individual slices tightly and place them in a freezer-safe container or bag.
Freeze for up to 2 months for the best quality.
Thaw overnight in the refrigerator before reheating in the oven until completely warmed through.
Common Mistakes to Avoid
One common mistake is failing to properly drain or cook watery vegetables. Excess moisture can make the custard watery and the pastry soggy.
Another mistake is overbaking the quiche. The center should be just set with a slight jiggle when it comes out of the oven. It will continue cooking gently from residual heat as it rests.
Cutting the quiche immediately after removing it from the oven can also cause the filling to spread. Give it at least 10 minutes to settle before slicing.
Finally, avoid using excessive salt if your cheese is already quite salty. Gruyère and sharp cheddar can contribute significant seasoning to the finished dish.

Frequently Asked Questions
Can I use leftover chicken?
Yes. Leftover roasted, baked, or grilled chicken is perfect for this recipe. Simply dice it into bite-sized pieces before adding it to the leek mixture.
Can I make this quiche without a pastry crust?
Yes. You can make a crustless chicken and leek quiche by greasing the baking dish well and pouring the filling directly into it. The cooking time may need to be adjusted slightly.

Yes. You can replace some or all of the heavy cream with whole milk for a lighter quiche. Keep in mind that the custard will be slightly less rich and creamy.
Why is my quiche watery?
Watery quiche is often caused by excess moisture from vegetables or undercooking. Make sure the leeks are cooked properly and allow the finished quiche to rest before slicing.
