Place 4-6 bone-in, skinless chicken thighs into the bottom of a greased slow cooker.
Add 2 large sweet potatoes, 2 15oz cans fire-roasted tomatoes, 14.75 oz can cream-style corn, 3 large carrots , 2 stalks celery, 1 small onion, 1½ tablespoon Worcestershire sauce, 1 tablespoon tomato paste, 1 tablespoon garlic, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon smoked paprika, and 3 cups chicken broth
Stir to combine, then cover and cook on low for 6-8 hours or high for 3-4 hours.
Stew is ready to serve when all potato pieces can be easily pierced with a fork and chicken reaches an internal temperature of 165℉
Add salt and pepper to taste, if needed
Optional: To thicken, make a potato starch slurry by stirring 1 tablespoon of potato starch with 2 tablespoon cold water. Pour slurry into hot slow cooker and stir to combine. You should see it start to thicken within 30 seconds or so. This can be doubled if you prefer it extra thick.
Bone-in chicken pieces can be served whole in the stew. They will natually start to fall apart as you stir/serve. No need to remove or shred them.
