Make this rich, delicious stuffing a part of your next holiday feast!
Preheat oven to 350°F. Butter a 3-quart or 9- by 13-inch baking dish. Heat oil in a large skillet over medium heat. Add sausage and cook, breaking it up with a spoon, until no longer pink. Transfer to a bowl with a slotted spoon. Reserve skillet.
Add onion and celery to reserved skillet. Season with salt and pepper. Cook, stirring occasionally, until tender, 5 to 7 minutes. Add sage and cook until fragrant, about 1 minute. Transfer to bowl with sausage, and let cool 5 minutes. Add parsley, egg, and bread, and stir to combine. Add stock, stirring until it is almost absorbed. Transfer to prepared pan. Dot with butter. Bake until warmed through and the top is crusty and brown, 40 to 45 minutes.
