Onion Pie – Tips & Tricks

  • As a side dish, a green salad brings freshness to the plate.
  • With the Alsatian onion cake, also known as “Tarte aux oignons”, the filling is placed on a shortcrust pastry. The popular quiche Lorraine is similar to this onion pie. Only fewer onions and cheese are used for the filling.
  • Little time? Then use a hearty quark and oil dough instead of yeast dough as the basis for the onion cake – it doesn’t have to go. You can take over the topping.
  • For a vegetarian onion tart, you can simply leave out the bacon cubes or replace them with finely chopped smoked tofu.
