Prepare Ingredients: Start by rinsing the baby potatoes under cool water and then slicing them in half. Pat your chicken breasts dry with paper towels, and season both sides generously with salt and black pepper for optimal flavor.
Layer the Crockpot: Arrange the halved baby potatoes evenly at the bottom of the crockpot to form a sturdy base. Next, place the seasoned chicken breasts on top of the potatoes in a single layer.
Make the Garlic Parmesan Sauce: In a mixing bowl, whisk together the heavy cream, grated Parmesan cheese, minced garlic, Italian seasoning, and onion powder until the mixture is smooth and all ingredients are thoroughly combined.
Combine and Cook: Carefully pour the garlic Parmesan sauce over the chicken and potatoes in the crockpot. Use a spatula to ensure everything is evenly coated in the sauce. Place the lid securely on the crockpot.
Cook: Set your crockpot to low heat and cook for 6-7 hours, or on high heat for 3-4 hours. The chicken should be fully cooked, and the potatoes should be tender when pierced with a fork.
Finish and Serve: Once cooking is complete, gently stir the mixture to meld the flavors together. To enhance the dish's freshness and color, sprinkle freshly chopped parsley on top right before serving.
Enjoy: Dish out the creamy chicken and potatoes while they are still warm. You can serve this delightful meal straight from the crockpot for a rustic feel or plate it elegantly to impress your guests.
