The ever-popular lardon-laced quiche Lorraine is off limits for Jews who eschew pork. In an effort to adapt the regional specialty to fit their dietary limitations, the Jews of Alsace and Lorraine created this onion tart, which I find delicious. I learned how to make it from the great chef André Soltner, who, before he came to America, worked for a kosher caterer in his native Alsace. Trust me, you won’t miss the bacon.
Cooks' Note
You can substitute prepared puff pastry for the crust.
