Clean out the inside of the chicken by removing any extra parts or packaging and discard.
Add the carrots, onion and celery to the bottom of the slow cooker. Add the chicken.
Pour over the melted butter and sprinkle over the thyme, sage, paprika, salt and pepper.
Cover and cook on low for 7-8 hours or HIGH for 5-6 hours.
Remove chicken to a platter and cover with foil. Now you'll want to remove some of the liquid from the slow cooker, leave only 1.5 cups of liquid along with the veggies. (you can use the extra liquid for gravy or another recipe). Add the box of stove-top stuffing to the veggies and 1.5 cups of liquid in the slow cooker. Replace the lid. Let sit for 10 minutes. Fluff with a fork when the time is up.
I add the chicken back to the slow cooker with the stuffing for a pretty presentation. If I was just serving this to my family, I would slice and serve the chicken on the platter and serve the stuffing from the slow cooker.
What should I serve with this?You can serve the alone with just the chicken and stuffing, it's so good as is! If you would like to serve it with other sides I suggest one or more of these:
