Cippollini Onion Tart

We got a bunch of cippoillini onions from our crop share this year and couldn't figure out what to do with them. I came across this recipe for a rustic tart and was thrilled. Not only did it use all of the cippollini onions but it was super delicious and very pretty. The onions melt in your mouth and the tart has an amazing savory flavor. I would definatly serve this at a dinner party. I think this would work nicely as single serving mini tarts as well.

5. Add the wine and reduce until syrupy, about 6-8 minutes.
6. Transfer the pan to the oven and roast for 10 minutes.
7. Remove the pan from the oven and place the refrigerated dough on top of the onions. Prick the surface to let air escape.
8. Return the pan to the oven and bake until crust is golden brown, about 35 minutes.
9. Remove the pan from the oven and let stand for 5 minutes.
10. Place a serving platter upside down on top of the pan and turn both upside down together. Lift off the pan, leaving the onion tart on the serving dish. Serve immediately!
