arugula pesto christmas tree

Arugula Pesto Christmas Tree

Pesto is greens ground up with garlic. Add some cheese, nuts and olive oil, and you have a sublime sauce that can go on pasta, top bruschetta, or serve as a dipping sauce for artichokes. This is a winter version of the summer classic pesto made with basil. This combination of the sharp bitterness of arugula, walnuts, and the saltiness of the Pecorino-Romano cheese is a winner. For the holidays, we're going to use the pesto as a filling between puff pastry, and then cut it into a whimsical Christmas tree!

  • Cut out the shape of a Christmas tree out of the dough. Start by cutting two straight lines about 1" from the bottom, remember to keep about 1"uncut between the two lines (this will be the tree trunk).
  • From the end of each cut at the center of your dough, cut downward to complete the bottom of the tree and the trunk.

Notes

TIPS & TRICKS
– This fun whimsical recipe is a great centerpiece for your holiday entertaining.
It can assemble the morning of your party and is best baked right before serving.
– I like to serve it on a cutting board them people can break off the branches and cut up the “trunk”.
– From the scrap pieces of puff pastry that are left after cutting out the “big” tree. Makes a cute little Charlie Brown style Christmas tree. 
– To make a sweet treat substitute the pesto for Nutella.
