Ingredients

  • 1 10-ounce bag pearl onions
  • 2 1/2 cups 1/2-inch-thick diagonal slices peeled carrots (about 3/4 pound)
  • 2 1/2 cups 1/2-inch-thick diagonal slices peeled parsnips (about 3/4 pound)
  • 2 cups 1/2-inch cubes peeled rutabagas (about 3/4 pound)
  • 2/3 cup olive oil, divided
  • 1 pound crimini (baby bella) mushrooms, stemmed, caps halved
  • 6 large garlic cloves, peeled
  • 2 teaspoons dried thyme
  • 2 teaspoons dried crushed rosemary
  • 1 1/2 teaspoons dried rubbed sage
  • 6 cups 1/2-inch cubes
  • 3 large eggs, beaten to blend
  • 3 tablespoons unsalted butter, melted
  • 1 1/2 cups low-salt chicken broth

Method

  • Position 1 rack in top third and 1 rack in bottom third of oven; preheat to 425°F. Cook onions in small saucepan of boiling water 2 minutes; drain. Cool slightly; trim and peel. Place onions, carrots, parsnips, and rutabagas in single layer on large rimmed baking sheet. Drizzle 1/3 cup oil over and sprinkle generously with salt and pepper; toss to coat. Place mushrooms and garlic on another rimmed baking sheet; drizzle with remaining 1/3 cup oil, sprinkle with salt and pepper, and toss to coat. Roast root vegetables until tender and brown around edges, stirring every 15 minutes, about 1 hour. Roast mushrooms and garlic until tender, stirring once, about 30 minutes. Place root vegetables and mushrooms in large bowl. Place garlic in small bowl; mash with fork until pureed. Add pureed garlic, thyme, rosemary, and sage to vegetables; toss to coat. Season to taste with salt and pepper. DO AHEAD:
  • Place cornbread cubes on large rimmed baking sheet. Let bread cubes stand at room temperature to dry slightly, about 1 hour.
  • Preheat oven to 375°F. Butter 13x9x2- inch oval baking dish. Add cornbread cubes to vegetables; toss to distribute evenly. Add eggs; toss to coat. Drizzle with melted butter; toss to coat. Add broth and stir to combine (mixture will be very moist). Transfer mixture to prepared dish.
  • Bake dressing uncovered until lightly browned and crisp around edges, about 45 minutes.
