Pro Tips
- Let the quiche cool for at least 10 minutes before serving to allow it to set and make slicing easier.
- Experiment with different fillings such as ham, mushrooms, spinach, or sun-dried tomatoes.
- For a richer flavor, use all heavy cream instead of milk in the egg mixture.
- Sprinkle an even layer of additional cheese on top during the last 10 minutes of baking for an extra cheesy and crispy topping.
FAQ
Absolutely! Using a muffin tin or mini tart pans, you can make individual-sized quiches for easy serving and portion control.
The center of the quiche should be set but slightly jiggly when gently shaken. You can also insert a knife in the center and if it comes out clean, the quiche is done. The crust should also be golden brown.
Yes, you can use frozen vegetables but make sure to thaw and drain them first to prevent excess moisture in your quiche. You would not want a watery quiche!
