Preheat your oven to 350°F (175°C). Prepare a large baking dish (9x13 inches) by greasing it lightly with butter or cooking spray.

In a large skillet or frying pan, cook the ground sausage over medium heat until it's browned and cooked through. Use a spatula to break up the sausage into smaller pieces as it cooks. Once done, remove the sausage from the pan and set it aside in a large mixing bowl.

In the same skillet, melt the butter over medium heat. Add the diced onion and celery, and sauté until they become soft and translucent, usually about 5-7 minutes. Add the minced garlic and cook for an additional 1-2 minutes, being careful not to burn the garlic.

Place the stale bread cubes in the mixing bowl with the cooked sausage. Pour the sautéed onion, celery, and garlic over the bread and sausage mixture.

Sprinkle the dried sage, thyme, and rosemary over the mixture. Season generously with salt and pepper according to your taste preferences.

Slowly pour 2 cups of chicken or vegetable broth over the mixture, gently tossing and stirring everything together. Add more broth as needed to moisten the stuffing to your desired consistency. The bread should be moist but not overly soggy.

Transfer the stuffing mixture into the prepared baking dish, spreading it out evenly.

Cover the baking dish with foil and bake in the preheated oven for 30 minutes. After 30 minutes, remove the foil and bake for an additional 15-20 minutes or until the top is golden brown and slightly crispy.

Once done, remove the stuffing from the oven and let it cool for a few minutes. Garnish with chopped fresh parsley if desired before serving.
