Parmesan Asparagus Puff Pastry Tarts

Puff pastry can really elevate any dish. It's light and flaky and bakes up golden brown. I've always loved its versatility. It's the star of multi-layer desserts like a French Napoleon. Or twist it with parmesan for simple and thoroughly delicious cheese straws. Recipe developer Lily Ghodrati recently posted a video on TikTok featuring honey, nectarines, and puff pastry. She baked the tarts with the puff pastry on top and flipped them over after baking, very much like what you would do with the classic French dessert tarte tatin. Her video went viral, garnering over 45 million views. It has since spurred many other creators to share savory and sweet puff pastry videos using the same method with the puff pastry on top. The benefit of baking with the puff pastry on top of the filling is that the puff pastry stays flaky and crisp without the filling making it soggy.

I decided to hop on the upside down puff pastry train as well with parmesan asparagus tarts. I started with a layer of parmesan cheese, topped with asparagus and prosciutto, and then slathered in compound butter before finishing with a strip of puff pastry. When baked upside down, the parmesan forms a crispy crust. And the compound butter infuses everything while allowing the puff pastry to remain crispy. I used Challenge Unsalted Butter to make the compound butter. Challenge Unsalted Butter is 100% real cream butter—nothing artificial or synthetic.

There are a few things to keep in mind when working with puff pastry:

  • You can make your own puff pastry, but the only time I've done that is in culinary school. If you buy puff pastry, look for all butter dough. It makes a big difference.
  • Make sure the puff pastry is thawed, but it still needs to be cold. It shouldn't be room temperature. You want the buttery layers to remain separate. Work quickly once it is thawed.
  • Make clean cuts so you don't crush the layers, which would prevent it from puffing.
