Caramelized Onion & Goat Cheese Puffs

1.
Line 2 baking sheets with parchment paper or silicone baking mats.
Preheat the oven to 400 degrees F. 2.
Remove 1 sheet of the frozen puff pastry and set it on the counter to thaw, about 30 minutes.
3.
Place a 10-inch skillet over medium-low heat, allowing pan time to warm.
4.
Add butter, onions, salt and pepper, stirring until butter melts.
5.
Continue to cook over medium-low heat, stirring periodically, until onions are deep golden brown and very tender, about 25 minutes total.
6.
Roll the (now) thawed puff pastry sheet out on a floured surface to 1/8-inch thickness.
7.
Cut circles of pastry with a 1 1/2-inch round biscuit or cookie cutter.
Re-roll scraps and continue cutting to get 36 rounds.
(If you dont own a 1 1/2-inch cutter, then the rim of a shot glass will do.)
8.
Place the pastry rounds about 1 inch apart onto the prepared baking sheets.
9.
Dock each round with a fork by piercing the centers 3 times.
10.
Bake for 8 to 10 minutes, or until pastry has puffed and edges begin to turn a little golden brown.
11.
Remove the puffs from the oven and cool on baking sheets for 2 minutes.
Then lightly depress the centers of the puffs with a finger to form a small cup to hold the toppings.
12.
Place a pinch of the goat cheese crumbles in the center of each puff (about 3/4 teaspoon).
13.
Top the cheese on each puff with a pinch of the caramelized onions.
14.
Serve immediately.
