  • Total Time: 60 minutes
  • Yield: 6-8 servings 1x


Units Scale
  • 8 cups of cubed day-old bread (such as ciabatta or artisan sourdough bread), cut or torn into 3/4″ pieces
  • 1/2 cup butter or vegan alternative
  • 1 large white onion, diced
  • 3 cloves of garlic, minced
  • 4 celery stalks, diced
  • 2 carrots, petite diced
  • 1 cup of mushrooms, diced
  • 1 1/2 cup of vegetable broth or vegetable stock, more if needed
  • 1/4 cup fresh parsley, finely chopped
  • 2 tablespoons of chopped fresh sage
  • 1 tablespoon fresh thyme, chopped
  • 1 tablespoon fresh rosemary, chopped
  • Salt and pepper to taste


  1. Preheat your oven to 350°F (175°C) and lightly grease a large casserole dish.
  2. In a large skillet, heat the butter over medium heat. Add the onion, garlic, celery, and carrots to the melted butter and olive oil. Sauté until the vegetables are tender, about 5-7 minutes.
  3. Add the mushrooms to the skillet and cook for 3-4 minutes, until they have softened. Season with salt and freshly ground black pepper. 
  4. Combine the cubed bread, cooked vegetable mixture, parsley, sage, thyme, and rosemary in a large mixing bowl. Toss everything together until well mixed.
  5. Pour the vegetable broth over the bread mixture and gently stir to combine. The bread should absorb the liquid, but if it seems too dry, add a little more broth.
  6. Transfer the stuffing mixture to the greased casserole dish and spread it out evenly.
  7. Cover the dish with aluminum foil and bake in the oven for 30 minutes.
  8. After 30 minutes, remove the foil and bake for 10-15 minutes until the top is golden brown and crispy.
  9. Remove from the oven and let it cool slightly before serving. Enjoy!
