Adjust oven rack to center position and preheat oven to 400°F. Butter two 12-well muffin tins. Divide stuffing evenly between wells (you may not need all 24 wells). Transfer to oven and bake until golden brown and crisp all over, about 45 minutes. Let cool for 10 minutes. Run a thin metal spatula around each stuffin and carefully remove from tin. Serve.
