This deep-dish quiche has a rich and creamy filling with a fluffy, almost custard-like, consistency.
It may be the creamiest textured quiche you ever ate. The flaky crust is easy to make with a food
processor and it adds a perfect contrast to the filling. Ham, sauteed mushrooms, and caramelized
onions are a nice flavor combination but you can substitute your favorite ingredients if you prefer.
Bake this quiche in a 10-inch deep-dish fluted tart pan with a removable bottom. This is not a
quick-and-easy recipe, so allow yourself plenty of time to prepare and bake the quiche; it is a
luscious dish and well worth the time and effort. Add a green salad or some fruit for a great lunch
or brunch menu.
