Tips
Stack the two pie crusts before rolling to create a thicker, sturdier base that won't crack under the weight of the filling.
Pre-baking the crust for 6 minutes prevents a soggy bottom and ensures the crust stays crispy throughout.
Let the quiche rest 5 minutes before cutting to allow the custard to set properly for cleaner slices.
Good to Know
Refrigerate leftovers up to 3 days covered. Reheat individual slices in microwave 30-60 seconds or oven at 350°F for 10 minutes.
Assemble completely and refrigerate unbaked up to 24 hours. Add 5-10 minutes to baking time if baking from cold.
Cut into squares and serve warm or at room temperature. Pairs well with fresh fruit or a simple green salad.
Common Mistakes
Don't skip pre-baking the crust to avoid a soggy bottom
