Wash and chop the potatoes into bite-sized pieces. Toss them with olive oil, salt, pepper, garlic powder, and paprika until well-coated.
Place the seasoned potatoes evenly in the bottom of your slow cooker.
Season chicken breasts with salt, pepper, paprika, onion powder, and Italian seasoning.
Lay the seasoned chicken breasts on top of the layer of potatoes. Spread minced garlic evenly over each piece of chicken.
Pour enough Buffalo Wild Wings Garlic Parmesan Sauce over the chicken to coat it thoroughly. Cover and cook on low for 6–7 hours or high for 3–4 hours.
In the last 30 minutes, sprinkle shredded mozzarella cheese over the top. Cover to let it melt before serving.
