1-First Step: Prep the Bread and Vegetables. Preheat your oven to 350°F (177°C). Cut the rustic bread loaf into 1-inch cubes and spread on a rimmed baking sheet. Bake, stirring occasionally, for about 20–25 minutes until the cubes are dry and crisp. Meanwhile, finely chop the mushrooms, dice onions and celery, slice green onions (if using), and mince garlic for even cooking.

2-Second Step: Sauté the Mushrooms and Vegetables. Heat olive oil or butter in a large skillet or pot over medium heat. Add the finely chopped mushrooms and cook 5–8 minutes, stirring frequently, until their liquid has evaporated and they begin to brown. Stir in the onions, celery, green onions, garlic, sage, thyme, and oregano, and cook for another 5 minutes until vegetables soften and fragrances bloom. Add the maple syrup, season with salt and pepper, and adjust to taste.

3-Third Step: Combine Ingredients and Add Broth. Remove the skillet from heat and transfer the mushroom-vegetable mixture to a large bowl. Add the toasted bread cubes and half of the chopped parsley, reserving the rest for garnish. Pour in 2 cups of broth and mix gently. If using eggs, whisk them with ¾ cup chicken broth and add along with Parmesan cheese. Toss everything carefully to evenly combine. Add up to ¼ cup additional broth if needed to achieve moist but not soggy consistency.

4-Fourth Step: Bake the Stuffing. Grease a baking dish (8×8 or 9×13 inches). Transfer the stuffing mixture into it, spreading evenly. Cover with foil and bake for 30 minutes at 350°F. Remove the foil and bake an additional 10–30 minutes, depending on how crisp you like the top. The stuffing should be golden brown and deliciously crunchy on top while soft and moist inside.

5-Final Step: Serve and Garnish. Take the stuffing out of the oven and let it cool slightly. Garnish with the remaining fresh parsley for a vibrant touch. Serve your mushroom stuffing warm alongside main dishes or as part of a holiday spread. It can be made vegan, gluten-free, or adjusted easily to your preferred tastes and dietary needs.
