How to Make It
Preheat oven to 350°.
Arrange bread in a single layer on a large jelly-roll pan. Bake at 350° for 15 minutes or until crisp and toasted. Remove pan from oven; cool bread cubes.
Increase oven temperature to 375°.
Heat a large skillet over medium-high heat. Add oil to pan; swirl to coat. Add onion, celery, and bell pepper; sauté 5 minutes. Add sausage; cook 5 minutes or until sausage is done, stirring to crumble. Stir in chestnuts. Remove pan from heat; cool slightly.
Combine stock, 1/4 cup parsley, thyme, pepper, salt, and eggs in a large bowl, stirring with a whisk. Add bread to stock mixture; toss to combine. Let stand 5 minutes or until bread absorbs most of liquid, stirring occasionally. Stir in sausage mixture. Spoon dressing into a 2-quart glass or ceramic baking dish coated with cooking spray. Bake at 375° for 35 minutes or until top is lightly browned. Remove pan from oven; sprinkle with remaining 1 tablespoon parsley.
