Preheat the oven to 375 degrees F (190 degrees C). Line a baking sheet with parchment paper.

Combine cream cheese, salmon, chives, garlic, salt, and pepper in a bowl; mix well. Divide equally into pastry shells and place on the prepared baking sheet.

Bake in the preheated oven until bubbling, 25 to 30 minutes. Remove and cool to room temperature before serving.
