Instructions
Heat a large saute pan over high heat. Add the sausage and cook until golden brown. Remove with a slotted spoon to a paper-towel-lined plate.
Add butter to the rendered fat, then add onion, celery, and carrot and cook until soft. Add garlic and cook for 1 minute. Remove from heat and fold in sage. Transfer to a large bowl and cool slightly.
Preheat oven to 425°F.
Add the sausage, egg, and bread to the cooled vegetable mixture and mix to coat. Add enough chicken stock to moisten. Season with salt and pepper to taste.
Butter a large baking dish, transfer the mixture to it, and bake 25 to 30 minutes, until golden brown.
