This crock pot chicken and dumplings recipe uses store-bought biscuits for dumplings that are moist and tender once stirred into the savory mixture of creamy mushrooms, chicken and veggies. Using 2 cans of cream of mushroom soup cuts down on prep time. To give the chicken stew body, we use a flour and butter paste known as a beurre manié—a classic thickening agent for soups, stews and sauces.
