We saw this recipe on a new (to us), beautifully photographed food blog, O Pistachio. The tart is baked just like a tarte Tatin, with the pastry fitted on top of the caramelized onions. Then you invert the whole thing onto a plate to serve.
The pastry is a store-bought puff pastry, which makes the process easier, and Philomena, the author of O Pistachio, assures us that it isn't onion overload, since they are cooked down and sweetened.

We think this dish is so versatile. It could be an appetizer, sliced into thin pieces, a side dish to a pork tenderloin, or a main course, served with a big green salad. It might even taste good at room temperature, making it ideal for a summer picnic.
