This chicken casserole from Pint-sized Treasures is smothered in butter, Swiss cheese, chicken broth (oooh, I'm drooling!), mushrooms, and topped with a buttery cracker blend. It's complete perfection, and this recipe is better than my Grandma's chicken casserole! Add this delicious recipe to your meal planner. If you only bake one chicken casserole in your life, may it be this one!
