Quiche is one of those magical kitchen “cheats” that feels fancy, but behaves like a weeknight casserole with better posture. You whisk, you pour, you bake, and suddenly you have dinner that also works for breakfast, lunchboxes, and that moment at 9:30 pm when someone wanders in asking, “Is there anything to eat?”
This is my classic quiche base with a couple of mom-proof upgrades: we blind bake the crust so it stays crisp, we keep the custard rich but not heavy, and we handle watery fillings (looking at you, mushrooms and spinach) so you get clean slices instead of a sad puddle.
One important note: This recipe is written for a 9-inch deep-dish crust, which actually has the capacity to hold a generous custard plus fillings without drama. If you are using a standard, shallow crust, use the smaller custard option listed in the ingredients so your quiche stays in the pan where it belongs.
