Instructions

  • Preheat your oven to 350 degrees Fahrenheit.
  • Cut your defrosted puff pastry into 3 1/2 to 4 inch squares and press gently into 12 muffin cups. Place the muffin tins in the freezer for the dough to firm up while you're making the filling.
  • Heat a large skillet over medium high heat and add the butter.
  • When the butter is melted, add the diced onion, garlic, mushrooms, and thyme and saute until the vegetables are very soft. Add a splash of white wine and some salt and pepper too.
  • Turn off the heat and turn the mushroom mixture out onto a plate to cool.
  • Mix the softened cream cheese and the parmesan cheese in a bowl with a spoon and add the cooled mushroom mixture, stirring to combine.
  • Remove the muffin tins from the freezer and divide the cheese and mushroom mixture between the 12 puff pastry cups.
  • Top each one with a little bit more parmesan.
  • Mix the egg with a splash of water and brush it onto the parts of the puff pastry that are visible (hanging over the sides of the muffin cups).
  • Bake at 350 degrees Fahrenheit until the puff pastry is golden brown and the filling is bubbly (about 20 minutes).
  • For best results, serve immediately. 

Notes

To make ahead, assemble the appetizers up to one day ahead and store in the fridge until ready to make, covered in plastic wrap.
