Prepare Ingredients: Pat chicken breasts dry. Wash and halve baby potatoes, ensuring a uniform size for even cooking.
Make Garlic Parmesan Seasoning: In a medium bowl, combine olive oil, minced garlic, dried Italian seasoning, salt, and black pepper. Stir well to form a fragrant paste.
Assemble in Slow Cooker: Lightly grease the slow cooker. Arrange the halved potatoes evenly on the bottom. Place chicken breasts over the potatoes.
Add Seasoning and Cheese: Evenly pour the garlic-oil seasoning mixture over the chicken and potatoes. Sprinkle the 1/2 cup grated Parmesan cheese over everything.
Slow Cook: Cover tightly and cook on the LOW setting for 6-8 hours, or on HIGH for 3-4 hours, until the chicken is tender and easily shredded, and the potatoes are fork-tender.
Finish and Serve: Once cooked, gently stir the dish and garnish with fresh chopped parsley. Serve hot.
