These puff pastry tarts are so easy to make as an appetizer or main course. Topping pre-made puff pastry with mushrooms that have been sautéed in a delicious balsamic bath and then layered on melty cheese, these tarts are hard to beat!
2cupscremini mushroomssliced (they’re also called baby bella mushrooms!)
7ouncesgood-quality puff pastry doughcut into 2 rectangles
5ouncesgruyerejarlsberg or emmenthaler cheese, grated
3shallotscut into rings
1clovegarlicminced
3tablespoonsbutter
2tablespoonsbalsamic vinegar
2teaspoonssoy sauce
½teaspoondark brown sugar
4sprigs fresh thyme
Instructions
Preheat oven to 375 degrees.
Lay puff pastry dough rectangles on a greased baking sheet. Sprinkle both rectangles with a generous layer of cheese, leaving a crust-like border around the outside of the pastry with no cheese.
In a large skillet over medium heat, melt butter. Add mushrooms, shallot rings, garlic, dark brown sugar, soy, and balsamic. Stirring often, let mushroom mixture cook and soften for 8-10 minutes until mushrooms shrink to about half of their original size and the shallots soften and begin to caramelize. Turn the burner off and stir in thyme removed from 2-3 sprigs.
Use a slotted spoon to add mushroom mixture to the top of each pastry, leaving a border around the outside of each pastry uncovered.
After all mushroom mixture is used, sprinkle the top of each pastry with more cheese and a bit more thyme.
Crimp the edges of the pastries with fork (if you’d like to make these extra pretty!).
Bake for 21-26 minutes until pastries are golden brown. Let rest for 5 minutes before enjoying (with wine, of course!).
