Method
Make the filling
- Melt the butter in a 10-inch skillet over medium-high heat.
- Add the mushrooms and cook for 6 to 8 minutes, stirring often, until browned and their liquid has evaporated.
- Stir in the shallot, garlic, thyme, salt, and pepper, and cook for 1 minute.
- Remove the skillet from the heat.
- Stir in the cream cheese and Gruyère until combined.
- Transfer the filling to a bowl.
- Let the filling cool for 10 minutes.
Assemble and bake
- Preheat the oven to 400°F.
- Lightly coat a 24-cup mini muffin pan with nonstick cooking spray.
- Roll the puff pastry into a 12x8-inch rectangle.
- Cut the pastry into 24 2-inch squares.
- Press one square into each muffin cup.
- Divide the filling among the pastry cups.
- Beat the egg with the water.
- Brush the egg mixture over the exposed pastry edges.
- Bake for 15 to 18 minutes, until the pastry is puffed and golden brown.
- Cool the bites in the pan for 5 minutes before serving.
Notes
For the neatest bites, let the filling cool fully before assembling. Refrigerate leftovers in an airtight container for up to 3 days; freezing is not recommended. Use gluten-free puff pastry for a gluten-free variation, if available.
