Caramelized Onion Palmiers

A very happy holidays to all of you! I hope you get wherever you are going safely (even if that is just your own dining room). Travel safe and eat well!

If you’re looking for a fast (and even somewhat elegant) appetizer to take to a holiday party over the next week or so, just go ahead and move these Puff Pastry Palmiers to the top of the list.

They have three ingredients (okay 8 if you count a few pinches and dashes here and there). But, let’s just agree that it’s three main ingredients. They are excellent warm, but also very delicious at room temperature hours after baking.

And, I guess they somewhat resemble palm trees (palmiers) and that is a desired shape for baked appetizers, according to history. They are also sometimes referred to as elephant ears which sound less appetizing in my opinion.

So while you could call them trees or ears, the most realistic name is probably “The things that used to be there but are now gone.”

Puff Pastry Palmiers

Start by making Caramelized Onions

The key to good caramelized onions is patience. If you are doing one large onion, it’ll take about 30 minutes for them to cook down correctly. If you cook them too quickly, they will just burn.

Cut the onion into slices and add them to a pot with butter, brown sugar, vinegar, and a pinch of salt. Get these cooking over medium heat.

Stir these regularly as they cook down. They will cook down to about a quarter of their original volume and will smell really good.

If at any point you notice the onions getting too dark, reduce the heat and hit the pan with a splash of water to cool it down.

After about 25-30 minutes of cooking and stirring (occasionally not constantly), these were my finished onions.

Palmier Making

Assemble the Puff Pastry Palmiers

Could you make homemade dough for this? Absolutely, but using frozen puff pastry dough is really the way to go in my opinion. It makes them very easy to make almost on a whim rather than a huge cooking project.

Just thaw the dough according to the brand you are using and then roll out a sheet on a lightly floured surface.

Sprinkle the pastry with some crumbled blue cheese (a little goes a long way here).

Then pile on about half of your onions. These are really flavorful so you don’t need to go crazy with them.

One onion should be enough to make two sheets of puff pastry palmiers.

After that just roll up each end of the dough until they meet in the middle!

Then you can slice them up and transfer them to a baking sheet. I recommend brushing them with some egg wash to make sure they brown nicely. Sort of an optional step though.

Bake the puff pastry palmiers at 375 degrees F. for around 16 minutes until they are lightly browned around the edges.

Beautiful little guys.

Call them ears, call them trees, or call them palmiers. 

Just make them though and people will be calling for more!
