Ingredients
1/4 cup extra-virgin olive oil
2 large onions, chopped (6 cups)
4 leeks, white and pale-green parts only, quartered, finely chopped, and rinsed well (5 cups)
1 bunch celery, finely chopped (4 cups)
4 garlic cloves, minced
8 ounces shiitake mushrooms, stems and caps sliced
1 pound sweet Italian sausages, casings removed (for Sausage Stuffing)
10 cups dried white Pullman bread or sandwich bread, crusts removed, bread cut into 1/2-inch cubes (from 2 loaves)
2 cups dried apricots, coarsely chopped
1/4 cup chopped fresh sage
2 tablespoons fresh thyme
2 cups homemade or store-bought low-sodium vegetable stock
8 ounces (2 sticks) unsalted butter, melted
Coarse salt and freshly ground pepper
Preparation
Heat 2 tablespoons oil in a large straight-sided skillet over medium heat. Add onions, leeks, celery, and garlic. Cook until onions are translucent and tender, about 20 minutes.
Add mushrooms, and cook until soft, about 5 minutes. Transfer mixture to a plate, and let stand until cool, about 5 minutes.
If making sausage stuffing: Return skillet to medium heat, and add remaining 2 tablespoons oil. Stir in sausage, and cook, breaking into small pieces, until browned, about 9 minutes. Remove from skillet using a slotted spoon, and transfer to paper-towel-lined plates. Let drain.
Combine onion-mushroom mixture, bread, apricots, sage, and thyme in a large bowl. Just before baking, pour stock and melted butter over top of mixture. Season with salt and pepper. Mix to combine.
To make sausage stuffing: Transfer 5 cups stuffing to another large bowl, and mix in sausage.
Let stuffings stand for 10 minutes, allowing bread to soak up liquid.
To cook mushroom stuffing: Preheat oven to 375 degrees. Place stuffing in a 9-by-13-inch baking dish, and bake until top is crisp and stuffing is heated through, 50 to 55 minutes. Let stand for 10 minutes before serving.
To cook sausage stuffing, follow directions for stuffing spice-rubbed roast turkey (recipe above), or preheat oven to 375, transfer stuffing to a 9-by-13-inch baking dish, and bake until top is crisp and stuffing is heated through, 45 to 50 minutes. Serve warm.
