Mushroom and Leek Quiche

Posted on March 20, 2013
Hi, Everybody! Happy First Day of Spring! I love sharing my favorite things with you all, and this Mushroom and Leek Quiche is definitely one of my favorite things to make! The crust is wonderfully soft, buttery and flaky, and the filling is deliciously creamy and satisfying, filled with mushrooms and leeks. The original recipe comes from The Williams-Sonoma Baking Book, which is one of my favorite cookbooks, but I have lightened the recipe up a little bit by using fat-free milk and just a little bit of half-and half instead of whole milk and heavy cream! Served with a great fresh salad, this makes for the perfect springtime lunch or dinner!

 MUSHROOM AND LEEK QUICHE
(Adapted from The Williams-Sonoma Baking Book)
*Makes one 9-inch round quiche*
 .
YOU WILL NEED
PASTRY
1 1/2 cups all-purpose flour
1/2 tsp salt
1/2 cup (4oz) unsalted butter, diced
1 large egg
2 – 3 tbs ice water
 .
FILLING
2 cups fat free milk
1/4 cup half-and-half
1 tbs Dijon mustard
1/2 tsp salt
1/4 tsp pepper
3 large eggs
2 large egg yolks
10oz mushrooms
2 – 3 leeks
1 shallot, finely diced
3 tbs olive oil
;
.. 
DIRECTIONS
,

1. First, make your quiche dough, by combining the flour and salt. Next, add chilled, diced butter and mix until the mixture resembles coarse meal. Then, add the egg and mix for a couple of seconds. With the mixer running, add the ice water (add as much as you need for a dough to form) and mix until you get a soft dough. Wrap the dough in plastic wrap and refrigerate for about an hour.

2. To make your filling, saute your shallot in 2 tbs of olive oil. Once it has softened, add the sliced mushrooms (I used Portabella and Button mushrooms) and cook until the mushrooms have softened and browned a little bit. Take them out and set them aside (place them on some paper towels to get as much grease and moisture out of them), and add the remaining tbs of olive oil to your pan, and cook your sliced leeks until they are tender. Add them to the mushrooms.

3. Take your dough out and roll it out to fit inside a 9-inch pie dish. Grease the dish, place the dough inside and prick the bottom of pastry with a fork several times, so it doesn’t rise while the quiche bakes. Cover the prepared baking dish with the crust inside with some plastic wrap and refrigerate it again until you are ready to bake the quiche.

4. In another bowl, whisk together the milk, half-and-half, salt, pepper, Dijon mustard, eggs and egg yolks. (The original recipe called for whole milk and heavy cream, but I lightened it up with fat-free milk and half-and-half). Preheat your oven to 375deg F and take your quiche crust out of the refrigerator. Evenly spread the mushrooms and leeks on the bottom, then slowly pour the milk and egg mixture over the top. Bake for about an hour, or until the crust is golden brown and the center of the quiche no longer jiggles. (I covered my quiche with foil after about 30 minutes of baking so the crust wouldn’t burn) Let cool for 10 minutes before serving. (*Note: If the quiche releases some liquid it’s totally fine, it’s just the moisture that the mushrooms release!)

Happy Baking, Everyone!
