Preheat oven to 400°F. Line a baking sheet with parchment paper.
In a bowl, mix pumpkin purée, ricotta, Parmesan, garlic, sage, salt, pepper, and cooked bacon pieces or cooked Pancetta (if using) until smooth.
Roll out pie crust and cut into 12, 3-4-inch circles with a biscuit cutter.
Place 1–2 tablespoons of filling in the center of 6 of the circles. Place a top circle of pie crust dough over the tops. Press edges with a fork to seal.
Brush tops with egg wash, then cut a small slit in each for venting.
Bake for 18–20 minutes, or until golden brown.
Garnish with extra sage and serve warm.
