Layer the potatoes: Add the whole baby Yukons to the bottom of your crockpot.
Season and add the chicken: Season chicken breasts with salt, pepper, paprika, and Italian seasoning, then place them directly on top of the potatoes.
Mix the sauce: In a small bowl, whisk together melted butter, minced garlic, chicken broth, cream, and Parmesan until smooth and creamy.
Combine: Pour the sauce evenly over the chicken and potatoes.
Cook: Cover and cook on Low for 4–5 hours, or until the chicken is tender and the potatoes are fork-soft.
Serve: Gently stir to coat everything in the sauce, sprinkle with parsley, and serve with steamed green beans for a complete meal.
