Add onions, celery and carrots to your slow cooker. Sprinkle with ¼ cup of flour and poultry seasoning and stir until coated.
Stir in wine and one cup of the broth and stir until everything is mixed up.
Add the chicken and remaining broth, give it all a stir, cover and cook on low setting for 6 hours.
After six hours, remove chicken from cooker and shred into bite sized pieces with two forks. Return chicken to cooker and stir.
Make dumplings by mixing dry ingredients together in medium mixing bowl. Stir in milk and butter until combined. Drop 1/4 cup amounts of dumpling dough around the edges of the slow cooker (you should have about 8 dumplings) and cover. Continue cooking on low for another hour.
Serve in soup plates and enjoy!
Notes
Chicken: We like chicken breasts for this recipe, but you can swap in boneless chicken thighs if you prefer. Or use a combo!
Poultry Seasoning: Look for this spice mixture in (yep!) the spice aisle of your supermarket.
Chicken Broth: As always, we recommend the kind in the box for the freshest flavor, but whatever kind you have on hand will work.
