Recipe Notes & Tips:
- Par bake the crust: A short pre bake helps prevent a soggy bottom and keeps the crust crisp once the egg whites bake.
- Prick the crust: Fork pricks help release steam so the crust bakes evenly and does not puff.
- Pack the filling lightly: Add spinach and tomatoes first, then cheese, so the veggies stay evenly distributed instead of floating.
- Do not over bake: Pull the quiche when the center is just set since it will finish firming up as it rests.
- Rest before slicing: Let it rest for 10 minutes so the slices hold their shape and the filling stays clean.
How to Store:
Refrigerator: Store egg white quiche in an airtight container for up to 4 days.
Reheat: Warm slices in a 325°F oven until heated through for the best texture. The microwave works too, but the crust will soften.
Freezer: Freeze individual slices for up to 2 months. Thaw overnight in the fridge, then reheat in the oven until hot.
Egg White Quiche FAQs:
Par baking the crust is recommended for egg white quiche because it helps prevent a soggy bottom. A short pre bake lets the crust set before the egg mixture is added.
To keep egg white quiche from getting watery, avoid adding wet vegetables and do not overload the filling. Using fresh spinach and baking until the center is set also helps the quiche hold its texture.
Egg white quiche is done when the center is set and no longer jiggly. If you insert a knife near the center, it should come out mostly clean and the edges should look lightly puffed.
