Instructions

1. 1.

   Combine all dough ingredients in a bowl, cut through with a knife, then knead quickly into a smooth dough. Cover and chill for 30 minutes.

2. 2.

   Peel and dice the onions. Sauté in a pan over medium heat with oil until translucent.

3. 3.

   Whisk cream, crème fraîche, and eggs together; season with salt, pepper, and nutmeg. Fold in onions and cheese.

   Roll out the dough on a floured surface to a size slightly larger than the tart pan, then line the pan. Spread the egg‑cream mixture over the dough. Bake in a preheated oven at 225 °C (200 °C fan) for about 30 minutes; cover with foil if needed. Let cool briefly before slicing.
