Add the chicken to the bowl of your slow cooker, then top with the seasonings. Spread the vegetables evenly out overtop of the meat.
3 large boneless, skinless chicken breasts, 1/2 tsp black pepper, 3/4 tsp garlic powder, 1/2 tsp onion powder, 1/2 tsp dried parsley, 1/2 tsp dried thyme, 1/2 tsp dried oregano, 1 cup diced carrots, 1 cup thinly sliced celery, 1 small yellow onion
In a large mixing bowl add 4 cups of broth, cream of chicken soup, and the cream. Stir the mixture together until evenly combined then pour it evenly out over the meat and vegetables in the slow cooker.
6 cups chicken broth, 2 10.5 oz cans condensed cream of chicken soup, 1/2 cup heavy cream
Cover and cook on LOW for 4-6 hours. Low is best because High can have the chicken and cream mixture burn and stick to the bottom of the slow cooker.
An hour before the soup's done, transfer the chicken to a cutting board, shred, then return it to the slow cooker.
Whisk together the cornstarch and water in a small bowl until evenly combined. Whisk the slurry into the slow cooker and stir to combine then continue cooking.
2 tbsp cornstarch
30 minutes before the soup's done add the frozen pierogi to the pot, cover, and cook on HIGH for 15 minutes. Stir well, then continue cooking another 15 minutes.
2 12.84 oz boxes frozen cheese pierogi
Add the remaining two cups of broth, if needed, to thin the soup.
Serve warm and enjoy!
