Onion tart with sumac, raisins and nuts

Adelicious onion tart in the fall is actually a classic, which I really super happy to prepare. With a glass of cold Federweisser and a view out the window – great! So the other day, when I was already squinting in the direction of autumn and thinking about onion tart, I had the idea to just rethink this classic and fuse it with Levantine flavors.

Onion tart with a difference!

Such an onion pie is a really super rich thing: A fluffy yeast dough and a filling of a whole lot of onions (and tears), egg, cheese, sour cream, etc… Actually crass that I had the idea for the variant with Sumac only came to me now. This cake is predestined for a fusion with the Levantine spice.

Since me onion tart always tastes best with a glass of sweet Federweisser, I thought that he then certainly also tolerates such a delicately sweet note. So then also raisins came with purely – are after all also grapes.

It becomes even richer with a good portion of roasted nuts. I have opted for aromatic walnuts and also for buttery pine nuts. At the very end then again cheese over it and off in the oven with the deliciousness! I found the smell when sautéing the onions with the sumac already wonderful, but what then came out of the oven in my nose, was just crazy good!

By the way, taboulé is actually quite fantastic with the onion tart, feel free to try it! Bon appetite!
