Place quiche on a piece of aluminum foil or a rimmed baking sheet, in case it overflows.
Check after 30 minutes. The crust should be golden brown. If the crust is getting too brown, loosely cover it with foil and reduce oven heat to 425°. Bake until only the center of the quiche is slightly wobbly. Let rest for at least 15 minutes before cutting. Serve with a side salad.
