We need to clarify what quiche Lorraine is not, and that is American. While delicious, US-American quiches are deeper, denser, and cheesier than their French counterparts. They’re more like breakfast sandwich-inspired pies! Classic French quiches, however, are shallow tarts filled with soft custards of eggs and dairy products.
Neither is vegan by default! Quiche Lorraine in particular also includes bacon. But once I had an egg-free omelet base (from developing my kuku sabzi recipe), a well-tested seitan bacon recipe, and a reliable dairy-free butter and heavy whipping cream, I had to attempt this dish.

Note that I retained the traditional characteristics of quiche Lorraine. Source a tart pan with a removable bottom, and expect a jiggly filling even when done. Moreover, save my recommended dairy-free cheese for other applications; it has no place here!
Thank you, Julia Child, for popularizing quiche in the USA. Though I will never know your thoughts on veganism, I think you’d look forward to this dinner. Bon appétit!
Before proceeding, prepare 12-16 strips of Two-Day Seitan Bacon.

Prepare 12-16 strips Two-Day Seitan Bacon before proceeding. On baking day, keep “butter” and water chilled, but bring all other cold ingredients to room temperature. Make refrigerator space for Step 5.
Cube ½ cup (120 mL/113 g) cold “butter”. Add to food processor, then pulse repeatedly until mixture resembles uniformly damp sand.
Sandwich dough between 2, 14x14-in/36x36-cm pieces of parchment, then roll into a circle 4 in/10 cm wider than tart pan bottom. Lay paper-sandwiched dough flat in refrigerator 30 min to 1 hr.
Set crust on a baking sheet. Using a fork, dock bottom. Gently snug an oversized piece of foil on top, then evenly apply pie weights (or dried beans designated as pie weights). Bake on bottom rack 25-30 min.
Remove crust from oven and reduce temperature to 375°F/190°C. Lift foil and hot weights off crust, then pour in and level filling.
Dice and equally distribute 1 Tbsp (15 mL/14 g) “butter” on top of quiche, then bake on middle rack about 45 min, until filling has puffed, “butter” topping has been absorbed, and a knife inserted into the center pulls out clean.
Cool 15 min before slicing. Bon appétit!
This is just one of many things you can make with my seitan bacon! Others include, but are by no means limited to, vegan split pea and 15-bean soups.
