Savory Onion Quiche

Makes six to eight servings.

Sour Cream Tart Pastry or Classic Tart Pastry
2 large onions, thinly sliced
¼ cup butter
1 tbsp. chopped fresh oregano
½ tsp. salt
Dash of cayenne pepper
1 cup (4oz.) shredded Swiss cheese
3 eggs
1 ½ cups light cream (or ¾ cup light cream and ¾ cup sour cream) 

On floured surface, roll pastry into a 14-inch circle. Transfer to deep dish pan. Turn edges of dough under, trimming if needed, shaping so that edge is flush with rim of pan. Prick bottom and sides with a fork. Bake at 375º for 15 minutes, following the directions for a baked pastry shell. Let cool about 20 minutes before filling. 

Sauté onions in butter until soft and folder. Add oregano, salt, and cayenne pepper. Spoon onions into prepared pastry, and sprinkle top with shredded cheese. Beat the eggs with the cream until thoroughly mixed. 

Pour egg mixture over surface of prepared quiche. Bake at 375º for 35 to 40 minutes until center is just set. Cool on a rack about 10 minutes before serving.

For Savory Onion-Tomato Quiche, omit oregano in seasoning onions. Toss Swiss cheese with 2 tbsp. flour. When assembling quiche, sprinkle with only half of the cheese, then arrange slices of a large, “meaty” tomato in a circular pattern on top. Sprinkle tomatoes with 1 tbsp. chopped fresh basil and the remaining cheese. Continue with recipe as directed.
