1 loaf day-old rustic Italian bread (about 1 pound), trimmed of crust and cut into 3/4-inch cubes (about 8 cups)
1 pound fresh chestnuts
1 pound sweet Italian sausage
1 T. extra-virgin olive oil
2 medium onions, finely chopped
4 celery stalks, finely chopped
4 garlic cloves, finely chopped
1/2 cup dry white wine
1/2 cup homeade or low-sodium store-bought chicken stock
1 T. chopped fresh thyme
2 T. chopped fresh sage
2 T. chopped fresh flat-leaf parsley
2 tsp. coarse salt
Freshly ground pepper
2 large eggs, lightly beaten
Unsalted butter, for baking dish

Let bread cubes stand on a baking sheet at room temperature 3 hours to dry. Lay each chestnut flat on a work surface, and cut an X in the pointed tip of shell with a paring or chestnut knife. Bring a medium pot of water to a boil. Boil chestnuts 2 minutes; remove pot from heat. Remove chestnuts with a slotted spoon; peel away shells. Quarter nutmeat; transfer to a large bowl. Add bread. Preheat oven to 350 degrees. Split sausages; scrape meat into a large saute pan set over medium heat; crumble with a fork. Cook, stirring occasionally, until cooked through, about 7 minutes. Add oil; swirl pan. Add onions, celery, and garlic. Reduce heat to medium-low. Cook, stirring occasionally, until vegetables are soft, 15 to 17 minutes. Add to bread mixture. Add wine to pan. Scraping up any brown bits from bottom with a wooden spoon, cook over medium heat until wine is reduced by half. Add to bread mixture. Add stock to bread mixture; toss. Add thyme, sage, and parsley. Add the salt, and season with pepper. Stir in eggs. To bake stuffing: Place stuffing in a buttered 9-by-13-inch baking dish; cover with foil. Bake 30 minutes; remove foil. Bake until golden brown, about 25 minutes. To cook in turkey: Stuff as directed. Place remaining 5 cups stuffing in a buttered 8-inch square baking dish; bake as directed above.
