Common Questions and Answers
Q: Why is my quiche watery?
A: This usually happens when vegetables aren’t properly pre-cooked to remove excess moisture. Make sure to sauté vegetables thoroughly and let them cool before adding to the quiche.
Q: Can I make this ahead of time?
A: Yes! You can prepare the entire quiche up to 24 hours in advance. Store unbaked in the refrigerator, covered tightly with plastic wrap.
Q: How do I know when the quiche is done?
A: The quiche is done when the edges are set but the center still has a slight jiggle. A knife inserted near the center should come out clean.
Q: Can I add meat to this recipe?
A: Absolutely! Pre-cooked bacon, ham, or chicken can be added. Just ensure the meat is well-drained to prevent excess grease.
Q: Why did my vegetables sink to the bottom?
A: This can happen if the vegetables are too heavy or wet. Try cutting them smaller and removing excess moisture before adding to the egg mixture.
Troubleshooting Guide

Uneven cooking | Oven hot spots | Rotate dish halfway through baking |
Cheese too browned | Too high temperature | Cover with foil if browning too quickly |
