How high do you put the oven on whenbaking keish?

When baking a quiche, preheat the oven to 375°F (190°C). This temperature allows the crust to become golden and crisp while ensuring the filling cooks through evenly. Bake the quiche for about 35 to 45 minutes, or until the filling is set and the top is lightly browned. Always check for doneness by inserting a knife into the center; it should come out clean.
