Simple Classic Stuffing

Preheat oven to 250°. Grease a 13x9x2" baking dish with unsalted butter and set aside. Scatter 1 lb. good-quality day-old white bread, torn into 1" pieces (about 10 cups), in a single layer on a rimmed baking sheet. Bake, stirring occasionally, until dried out, about 1 hour. Let cool; transfer to a very large bowl.

Meanwhile, melt ¾ cup (1½ sticks) unsalted butter in a large skillet over medium-high heat; add 2½ cups chopped yellow onions and 1½ cups (¼" slices) celery to melted butter. Stir often until just beginning to brown, about 10 minutes. Add to bowl with dried bread cubes; stir in ½ cup chopped flat-leaf parsley, 2 Tbsp. chopped fresh sage, 1 Tbsp. chopped fresh rosemary, 1 Tbsp. chopped fresh thyme, 2 tsp. Diamond Crystal or 1 tsp. Morton kosher salt, and 1 tsp. freshly ground black pepper. Drizzle in 1¼ cups low-sodium chicken broth or vegetable broth and toss gently. Let cool.

Preheat oven to 350°F. Whisk 2 large eggs and remaining 1¼ cups low-sodium chicken broth or vegetable broth in a small bowl. Add to bread mixture; fold gently until thoroughly combined. Transfer to prepared baking dish, cover with foil, and bake until an instant-read thermometer inserted into the center of dressing registers 160°, 35–40 minutes.

Uncover dressing; continue to bake until set and top is golden brown and crisp, 35–45 minutes longer. Make Ahead: Dressing can be baked (before browning) 1 day ahead. Uncover and let cool, then cover and chill. Uncover and bake until top is browned and crisp, 45–60 minutes.
