Boil boneless chicken breasts for about 20 minutes on low boil or until cooked thoroughly.
Allow chicken breast to cool for a few minutes.
Once chicken has cooled, shred it using a fork or a hand mixer. Yes, a hand mixer works great!
Place shredded chicken in the slow cooker. Then add all purpose seasoning and garlic pepper, to taste. Give it a good toss to make sure chicken is seasoned well.
Next, add butter, cream of chicken, and onions (or all vegetables) to the slow cooker.
Pour chicken broth over chicken, butter, cream of chicken, and vegetables to cover. You can taste your broth and adjust your seasoning, if needed.
Add lid to slow cooker and cook for 2 hours and 30 minutes on low.
30 minutes before serving, place pieces of biscuit dough in the slow cooker one by one. You can make your dough different sizes.
Cook dough 20-25 minutes minutes or until the dough is no longer raw in the center.
Turn slow cooker to warm setting.
Serve chicken and dumplings topped with fresh parsley and enjoy!
