In general, a fully baked quiche will keep in the fridge for 3 to 4 days. Yes, that’s it. But don’t groan—that’s actually a perfect window for lazy weekday breakfasts or impromptu snacks.
Think of it like a savory custard pie. It’s not a rock; it’s a delicate, eggy cloud. Treat it with the same respect you’d give a good slice of cheesecake, not a leftover pizza.
