These bite-sized mini quiche Lorraine cups feature a flaky homemade pastry filled with creamy custard, smoky bacon, Gruyère cheese, and caramelized onions. Perfect for brunch gatherings, potlucks, or a comforting treat any time.
For extra flaky pastry, keep all ingredients cold and don’t overwork the dough. Pre-bake pastry shells for 4-5 minutes if you want crispier bottoms. Substitute bacon with mushrooms or spinach for a vegetarian version. Freeze unbaked pastry and filling separately for easy batch prep.
