Onion tarte: very thin and deliciously hearty

Whether fresh for dinner or as a meal prep …

… onion cake always tastes delicious! Granted, it takes a bit longer than my classic meal prep recipes. But it’s worth it! The pieces can be frozen well – if something is left over!

Cut into small pieces and spread with pumpkin, the onion cake becomes a tasty little appetizer. Basil leaves and some Greek yoghurt give a fresh note and you will see: the appetizers are gone in no time!

Onion tarte belongs to autumn like new wine! And it’s easy to freeze – so it’s perfect for Meal Prep.



For the dough:

  • 300 g spelt flour 1050
  • 100 g of butter lard
  • 120 ml of water
  • 1/4 teaspoon salt

For covering:


  • 1.5 kg (vegetable) onions
  • 1 tablespoon of butter lard
  • freshly ground pepper
  • 3 eggs
  • 125 g crème fraîche
  • 125 g of cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground caraway


Preheat the oven to 180 °.



  • Boil the clarified butter with the water in a small saucepan.
  • Mix flour and salt
  • Knead briefly with the butter-lard-water mixture and allow to cool

For the filling:


  • Peel onions, halve and cut into thin rings
  • Simmer in 1 tablespoon of clarified butter until golden, stirring again and again.
  • Season with a little salt and pepper.
  • Mix the eggs, crème fraîche, cream and the spices so that a homogeneous mass is produced
  • Roll out the dough on a sheet of baking paper.
  • Prick several times with a fork, so that the dough does not blow
  • Distribute the onions on top
  • Pour the egg mass evenly over the onions.
  • Bake 35 minutes on the bottom rail in the oven.


The main work of this recipe is the preparation of the onions. It makes sense to take  the big, slightly milder onions. This makes peeling easier and everything goes a little faster. The recipe is for a baking sheet. The ready-made onion cake can be easily stored in the refrigerator for one day, or frozen. For this, cut any size pieces and freeze them on a tray. Once frozen, they can be easily stacked in a box.
