Preheat your oven to 400°F / 200°C.
Using a 1-inch / 2. 5cm round cookie cutter, cut 24 disks from the thawed puff pastry sheets.
Arrange the disks on an ungreased baking sheet.
Place a second, matching baking sheet directly on top of the pastry disks. This clever trick keeps them from rising too high, creating the perfect flat base.
Bake for about 15 minutes, or until the disks are crisp and a beautiful golden brown.
Remove from the oven.
Gently press the center of each warm disk with the tip of a small knife or the back of a spoon to create a slight indentation for the toppings.
Spoon a small amount of marinara sauce into each indentation. Crumble a pinch of goat cheese over the sauce, and finish with a sprinkle of chopped fresh thyme.
To serve, pop the mini pizzas back into the warm oven for 1-2 minutes, just until the goat cheese softens and gets a slight shimmer.
Serve hot and enjoy!
