Ingredients

  • 3 cups Italian white bread cubed into 1-inch pieces
  • 3 tablespoons butter
  • 1 medium onion finely chopped
  • 1 cup celery finely chopped
  • 1 tablespoon fresh sage finely chopped
  • 1 tablespoon fresh parsley chopped
  • 1 teaspoon fresh thyme leaves optional, for extra depth
  • 3 cups mashed potatoes homemade or prepared instant, slightly thicker than usual
  • 2 tablespoons butter melted
  • ½ cup vegetarian chicken-style broth or vegetable broth
  • kosher salt and ground black pepper to taste

Instructions

  • Preheat the oven to 350°F. Line a baking sheet with parchment paper. Spray an 8x8-inch baking dish with non-stick cooking spray.
  • Spread bread cubes on a baking sheet in a single layer. Toast for 10 minutes, until dry and lightly golden. Set aside.
  • Set a large skillet over medium heat and add 3 tablespoons of butter. When the butter is melted, add the onion and celery. Cook for 3 minutes, stirring frequently, until softened.
  • Stir in sage, parsley, and thyme and cook 1 minute. Remove from heat.
  • In a large bowl, gently stir together the prepared mashed potatoes, toasted bread cubes, and sautéed vegetables. Add the 2 tablespoons of melted butter. Drizzle in broth a little at a time, stirring gently,  until mixture is moist but not soggy. Adjust seasoning to taste with salt and black pepper.
  • Transfer to the prepared baking dish. Bake at 350°F, uncovered, for 45–55 minutes, until the top is crisp and golden.
