Puff pastry, or pâte feuilletée, is a light and flaky pastry made from laminated dough. "Laminating" refers to the painstaking process of rolling and folding the dough over and over until hundreds of layers are formed. It is time consuming and difficult, which is why most people simply buy frozen puff pastry from the grocery store. Puff pastry can be used in both sweet and savory baked goods - like turnovers, palmiers, beef wellington, pinwheels, tarts, and more.

Ingredients

Scale

1 puff pastry sheet, defrosted
1 egg, whisked for egg wash

Cinnamon Apple Tart – Divide among two tarts

1/2 apple, sliced
1 tsp cinnamon
1 tbsp honey

Prosciutto & Brie Tart – Divide among two tarts

2 prosciutto slices
2 brie cheese slices
2 tsp honey
Black pepper

Cheddar, Shallot, & Thyme – Divide among two tarts

1/2 shallot, thinly sliced
1/4 cup shredded cheddar cheese
2 tsp honey
Fresh thyme

Instructions

Set the oven to 400 degrees.
Cut the thawed puff pastry sheet into 6 even rectangles. Cut the large sheet into 3 rectangles along the fold lines, then cut those in half.
Line a baking sheet with parchment paper. Then assemble the tarts, making sure to evenly space them.
Apple Cinnamon: First drizzle the honey (1/2 tbsp) on the parchment paper. Sprinkle cinnamon (1/2 tsp) on top. Next place the apple slices (4-6) on top of the honey and cinnamon, making sure to keep them compact enough for the puff pastry rectangle to fit on top. Add the puff pastry on top of the apples. Repeat this for another tart.
Prosciutto & Brie: Again drizzle honey (1 tsp) on the parchment paper. Layer one slice of prosciutto, then one slice of brie cheese on top. Add black pepper. Carefully place the puff pastry rectangle on top. Repeat this for another tart.
Cheddar, Shallot, & Thyme: Add a honey drizzle (1 tsp) to the parchment paper. Next place the sliced shallots on top of the honey and then the shredded cheddar cheese (2 tbsp). Sprinkle a little fresh thyme too. Then carefully place the pastry rectangle on top. Repeat this for another tart.
Once all of the upside-down puff pastry squares are assembled, gently press down on the edges of each one with a fork to seal and crimp them. Brush the top of each tart with a thin layer of egg wash.
Bake for 20-25 minutes. I have seen some people say much less time is required, so I recommend checking on yours at 10 minutes. The cooking time will depend on each oven.
Remove the puff pastry tarts from the oven and let cool for a few minutes before flipping over. Once cooled slightly, gently flip with a spatula.
Serve and enjoy!
