Best Ever Crock Pot Chicken and Dumplings

Step 1: Layer the Base: Layer the diced onion on the bottom of your crock pot. Place the chicken thighs on top of the onion in a single layer.
Step 2: Prepare the Sauce: In a mixing bowl, combine the cream of chicken soup, cream of celery soup, poultry seasoning, 2 tablespoons of chopped parsley, and black pepper. Stir all of the ingredients well, then pour the mixture over the chicken thighs in the crock pot. Pour the 2 cups of chicken broth over the top.
Step 3: Cook: Set the crock pot to high for 5 hours and close the lid. Do not open the lid until there is just 1 hour of cook time left.
Step 4: Add Vegetables & Shred Chicken: With 1 hour remaining, open the lid and pour in the defrosted mixed vegetables. Mix them into the crock pot well, using your spoon to shred the chicken thighs as you stir.
Step 5: Add Dumplings: Open the can of refrigerated biscuits, flatten each one, and cut each biscuit into 4 long slices. Layer the biscuit slices on top of the chicken mixture in the crock pot.
Step 6: Finish & Serve: Let the biscuits cook for the remaining 1 hour. Once the time is up, stir the mixture well to incorporate the dumplings into the casserole. Serve topped with freshly chopped parsley.
