A quiche is a French dish that typically consists of eggs, cream, and cheese baked in a pastry crust. There are many different variations of quiche, but the most important thing to remember is that the eggs should be cooked thoroughly.
The ideal temperature for cooking a quiche is between 350°F and 375°F. If the quiche is cooked at too low of a temperature, the eggs will not be cooked through and the center will be runny. If the quiche is cooked at too high of a temperature, the eggs will become overcooked and dry.
To ensure that your quiche is cooked perfectly, use an instant-read thermometer to check the internal temperature of the egg custard before removing it from the oven. The custard should register at least 160°F on the thermometer.
