Preheat the oven to 300 degrees Fahrenheit. Place 10 cups cubed sourdough bread onto a large baking sheet. Bake for 10 minutes, or until lightly toasted. Remove from the oven and set aside.
In a medium-sized skillet, cook and brown 1 pound ground sausage for 7-8 minutes over medium-high heat. Drain any excess oil and set aside.
Melt 12 tablespoons unsalted butter into a large pot over medium heat. Add 1 small diced onion, 1 ½ cups chopped celery, and 1 ½ cups diced carrots. Cook for about 10 minutes or until tender. Stir in 1 tablespoon minced garlic and cook for 1 minute.
Pour in 2 ½ cups chicken broth, ¼ cup fresh chopped parsley, 2 tablespoons fresh rosemary, 1 tablespoon fresh sage, 1 tablespoon fresh thyme, ½ teaspoon kosher salt, and ½ teaspoon fresh cracked black pepper. Stir and reduce the heat to a low simmer.
Stir the cooked sausage into the broth mixture. Add half of the toasted bread cubes and gently stir until all pieces are coated. Stir in the rest of the bread until it’s all coated and the liquid’s absorbed. Taste the stuffing and season with additional salt and pepper if needed.
Transfer the stuffing into a 13 X 9 X 2-inch baking dish. Bake for 25-30 minutes, or until the top is just golden brown. Serve warm and enjoy!
