Can I make this quiche ahead of time?
Yes. Assemble the quiches, cover with plastic wrap, and refrigerate up to 24 hours before baking. Add 5–10 minutes to bake time if baking from cold.
How do I know when the quiche is done baking?
The egg filling should be set at the edges but still slightly jiggly in the very center (about 1 inch). It will continue to set as it cools. Overbaking makes the quiche rubbery.
Can I use fresh pie crusts instead of frozen?
Yes. Use two 9-inch fresh or thawed pie crusts. Blind-bake them for 5 minutes at 375°F to prevent a soggy bottom.
What can I substitute for cheddar cheese?
Gruyère, Swiss, or fontina work well. Avoid soft cheeses like brie. Use the same 2-cup quantity.
Can I freeze a baked quiche?
Yes. Cool completely, wrap tightly in plastic wrap and foil, and freeze up to 3 months. Thaw overnight in the fridge and reheat at 350°F for 20–25 minutes.
