Ingredients
  

For the filling
  • 1 tablespoon olive oil for cooking
  • 1/2 medium onion diced onion
  • 8 ounces baby bella mushrooms chopped
  • 2 cloves garlic minced
  • Freshly cracked salt and black pepper to taste
For the pastry
  • 1 sheet frozen puff pastry thawed
  • 2 ounces Gruyère cheese shredded
  • 1 tablespoon Grated Parmesan cheese
  • 1/4 teaspoon dried thyme

Method
 

Preparation
  1. Preheat the oven to 375 degrees F (190 degrees C). Spray cups of two 12-cup mini muffin pans with nonstick cooking spray.
  2. Heat olive oil in a skillet over medium heat. Add the diced onion and cook until the edges begin to brown, about 3 minutes.
  3. Add the chopped mushrooms and minced garlic to the skillet. Cook until the mushrooms are soft, about 3 to 4 minutes. Season with salt and pepper.
  4. Transfer the cooked vegetables to a paper towel-lined plate using a slotted spoon to remove excess oil.
  5. Roll out the puff pastry sheet into a horizontal rectangle on a lightly floured cutting board.
  6. Use a pizza slicer to cut the pastry into 4 rows horizontally and 6 rows vertically, creating 24 squares (approximately 2 1/2 inches each).
  7. Press each dough square into a mini muffin cup, making sure to prick the bottom with a fork.
Assembly
  1. Divide the mushroom mixture among the pastry cups.
  2. Top each with shredded Gruyère and Parmesan cheese, then sprinkle with dried thyme.
Baking
  1. Bake in the preheated oven for 14 to 16 minutes, or until the pastry is puffed up and golden brown.
  2. Let them cool in the pans on a wire rack for 3 minutes before transferring the bites to a serving dish.

Notes

Serve these delicious puff pastry bites warm, straight from the oven. You can garnish with fresh herbs for a touch of color and flavor. To store any leftovers, place the cooled puff pastry bites in an airtight container. Keep them in the refrigerator for up to 3 days. If you want to reheat them, pop them back in the oven for a few minutes until warm. Thaw the puff pastry thoroughly before rolling out for easier handling. Feel free to experiment with different cheese varieties if Gruyère isn’t available.
