These Goat Cheese Puffs are the perfect little puff pastry bites you never knew you needed in life! They're a savory, sweet, and simply irresistible appetizer that's perfect for parties and holiday gatherings.
Place the prosciutto slices on a dry paper towel. Lay another towel on top. Cook for 1 minute on high in the microwave. Remove the top paper towel and allow the prosciutto to cool (meat will be slightly flexible but will crisp upon cooling). When completely cool, crumble prosciutto and set aside.
In a small bowl, beat egg and water with a fork and set aside. Lightly flour a work surface. Roll out the thawed puff pastry sheet to a 12x12-inch square. Using a pizza cutter, cut into 16 (3x3-inch) squares and then brush the edges of the squares with the egg mixture.
Place about 2 teaspoons of the goat cheese mixture in the center of each square. Fold the pastry over the filling to form triangles. Press the edges to seal. Crimp the edges with a fork.
Arrange 8 of the pastry triangles in the air fryer, leaving as much space as possible in between them. Set air fryer to 400°F for 10 minutes or until pastry is golden brown. Repeat with remaining pastry triangles.
