Preheat the oven to 425°. Grease a 4-quart baking dish. Spread the bread on a baking sheet and toast for about 10 minutes, until golden and crisp.
In a large nonstick skillet, heat 1 tablespoon of the olive oil. Add the sausage and cook over moderate heat, stirring occasionally, until browned, about 5 minutes. Add the leeks and garlic and cook until softened, about 5 minutes. Scrape the sausage mixture into a large bowl; wipe out the skillet.
In the skillet, heat 2 tablespoons of the oil. Add half of the mushrooms, season with salt and pepper and cook over moderately high heat, stirring occasionally, until deep golden, about 8 minutes. Transfer to the large bowl. Repeat with the remaining oil and mushrooms, seasoning with salt and pepper and transferring to the bowl. Add the bread, broth, eggs and the 1/2 cup of chopped parsley and mix well. Let stand for 5 minutes, allowing the bread to absorb the liquid.
Scrape the stuffing into the prepared dish and drizzle with the 3 tablespoons of melted butter. Cover and bake for 30 minutes. Uncover and bake for 30 minutes longer, until golden and cooked through. Serve the stuffing hot, garnished with parsley.
The cooked stuffing can be refrigerated overnight. Cover and reheat at 325° until warmed through.
