Herbed Oyster Stuffing

Preheat oven to 325 °F. Spread bread cubes in 2 shallow baking pans and bake in upper and lower thirds of oven, switching position of pans halfway through baking, until golden, 25 to 30 minutes total. Cool bread in pans on racks, then transfer to a large bowl. Meanwhile, cook bacon in a 12-inch heavy skillet over moderate heat, stirring occasionally, until crisp, about 10 minutes. Transfer to paper towels to drain, reserving fat in skillet. If bacon renders less than 1/4 cup fat, add enough oil to skillet to total 1/4 cup fat. Cook onions, celery, thyme, sage, garlic, salt, and pepper in fat in skillet over moderate heat, stirring occasionally, until vegetables are softened, 8 to 10 minutes. Transfer to bowl with bread cubes, then stir in bacon, parsley, butter, and oysters. Drizzle with stock, then season with salt and pepper and toss well. Transfer stuffing to a buttered 3- to 3 1/2-quart shallow baking dish. Bake, covered, in middle of oven 30 minutes, then uncover and bake until browned, about 30 minutes more.
