Directions

1. Preheat oven to 350°F. Coat a shallow 2 1/2- to 3-quart baking dish (such as a 9x13-inch pan) with cooking spray.
2. Melt butter in a large frying pan over medium-high heat. Add celery and onion and cook, stirring often, until tender, about 5 minutes (reduce heat to medium if vegetables start to brown too quickly). Remove from heat.
3. Whisk eggs, 2 1/2 cups chicken broth, the sage, and 1/4 teaspoon each salt and pepper to blend in a large mixing bowl. Add onion mixture, apples, and stuffing mix and toss gently until well mixed. If using cubed stuffing mix, let stuffing stand about 5 minutes; then stir, let stand another 5 minutes to soften slightly, and toss again. For any style of stuffing mix, stir in up to ½ cup more chicken broth if you like a more moist stuffing. Transfer stuffing to the prepared baking dish.
4. Bake stuffing until lightly browned and crusty, about 40 minutes. Season with more salt and pepper to taste if you like.
