First Step: Prep Ingredients Dice the onion and thaw frozen vegetables if using. Open and prepare soup cans, measure out broth, seasoning, and butter. Arrange refrigerated biscuits and have your slow cooker ready.

Second Step: Layer Ingredients in Slow Cooker Place diced onion and butter at the bottom of a 6-quart slow cooker. Lay the boneless, skinless chicken breasts on top. This layering allows flavors to infuse into the chicken as it cooks.

Third Step: Mix and Add Soups and Seasoning In a small bowl, whisk together condensed cream of celery soup, cream of chicken soup, chopped fresh parsley, poultry seasoning, garlic powder if using, and black pepper. Spread this mixture evenly over the chicken breasts in the slow cooker, creating a creamy flavor base.

Fourth Step: Pour Broth and Set to Cook Pour 2 cups of reduced sodium chicken broth over the mixture, ensuring the chicken is mostly submerged. Cover and cook on high for 4 to 5 hours or on low for 6 to 8 hours until the chicken is tender and can be shredded easily.

Fifth Step: Shred Chicken and Add Vegetables About one hour before serving (after approximately 4 hours on high or near end of low cook time), remove the chicken breasts from the slow cooker. Shred the chicken with two forks and return it to the slow cooker. Stir in the thawed frozen vegetables or peas and carrots to add nutrients and texture.

Sixth Step: Prepare and Add Dumplings Roll refrigerated buttermilk biscuits thin and flat using a rolling pin, then cut into strips or quarter regular-sized biscuits. Place these biscuit pieces evenly over the chicken and vegetable mixture in the slow cooker.

Seventh Step: Final Cooking of Dumplings Quickly replace the slow cooker lid and cook on high for an additional 60 minutes or until the dumplings are cooked through and tender but still slightly doughy. Avoid lifting the lid while cooking to maintain the consistent temperature needed for fluffy dumplings.

Final Step: Serve and Enjoy Give everything a gentle stir to slightly break up the dumplings, mixing all ingredients well. Serve warm, garnished with extra parsley if desired. This rich slow cooker chicken and dumplings dish is a comforting, nourishing meal perfect for family dinners.
