Thaw puff pastry in refrigerator for 2-3 hours or overnight.

Position top oven rack in the middle position and pre-heat oven to 375°F.

Open thawed puff pastry and carefully unfold, being careful not to crack it. Place puff pastry on a lightly floured surface. Gently roll pastry with a floured rolling pin into a large rectangle. Cut in half with a sharp knife and carefully wrap one portion in plastic before returning to the refrigerator. (Use the remaining portion within a day for another recipe or to double this one).

Place the remaining rectangle on a large, rimmed baking sheet lined with parchment paper or a Silpat™ baking mat.

Dock (pierce) the pastry inside the cut you just made with a fork just like you would a pie crust. Add the Brie in a single layer on top of the interior portion. Top with pear slices, then sprinkle with thyme leaves, cinnamon, and nutmeg. Brush top with maple syrup to evenly coat.

Create an egg wash by whisking one tablespoon of water with one egg yolk. Brush mixture over the outside exposed portion of the puff pastry before placing in oven.

Bake for approximately 15-18 minutes, or until the pastry “picture frame” puffs up and turns golden brown. Remove from oven and cool slightly before slicing and serving. Enjoy!
