We took a classic quiche recipe, bumped up the onion factor with three different types, and used a sharp Western white cheddar cheese.
1 sheet refrigerated pie dough for a 9-in. pie shell*
1 tablespoon butter
3 medium leeks (white and light green parts), thinly sliced and rinsed well
2 bunches green onions, trimmed and thickly sliced
1/2 medium red onion, cut into thin half-moons
1 teaspoon kosher salt, divided
1 cup half-and-half
1 tablespoon flour
3 large eggs
2 cups shredded sharp white cheddar cheese*
How to Make It
Preheat oven to 425°. Unroll pie dough into a 9-in. pie pan. Crimp edge. Line dough with parchment paper, fill with pie weights or dried beans, and bake until light golden, about 15 minutes. Remove paper and weights.
Melt butter in a large frying pan over medium heat. Add leeks, green and red onions, and 1/2 tsp. salt. Sauté until very tender but not browned, about 20 minutes.
Whisk half-and-half gradually into flour in a medium bowl until smooth. Whisk in remaining 1/2 tsp. salt and eggs until blended. Stir in cheese and three-quarters of onion mixture and pour into pie shell. Sprinkle remaining onions over quiche.
Bake until a knife inserted in center comes out clean, 20 to 30 minutes; cover edges with foil if they begin to darken. Let sit 10 minutes, then cut into wedges.
*We especially like Pillsbury pie dough. Look for Beecher's Flagship cheddar cheese sold at specialty shops.
This was really really good but i believe this makes more then just one pie!! We doubled the recipe and also used deep dish frozen pie plate shells and still, we ended up having to use 4 shells to use all the onion mixture!! That is ALOT of onions! It was ok though (except for having to run out to the store for more shells) because it just was soo good and makes for great left overs :) YUMMY!
