Prepare the Chicken: Generously season the chicken breasts on both sides with garlic powder, onion powder, Italian seasoning, salt, and pepper. Make sure the spices adhere well to the chicken for optimal flavor.
Layer Ingredients in the Crockpot: Begin by placing the diced Yukon gold potatoes at the bottom of your crockpot in an even layer. This will create a flavorful base for the chicken. Next, position the seasoned chicken breasts directly atop the potatoes.
Make the Sauce: In a medium mixing bowl, combine the chicken broth, heavy cream, and half of the grated Parmesan cheese. Whisk the mixture vigorously until it's smooth and well combined, ensuring no lumps remain.
Add the Sauce to the Crockpot: Gently pour the cream mixture over the seasoned chicken and potatoes in the crockpot. Take care to fully coat the chicken to infuse it with moisture and flavor during cooking.
Cook: Cover the crockpot with its lid and set the heat to low for 6-7 hours or to high for 3-4 hours. Cook until the chicken is beautifully tender and fully cooked through, reaching an internal temperature of 165°F (75°C).
Finish with Parmesan: During the last 30 minutes of cooking, sprinkle the remaining grated Parmesan cheese over the top of the chicken and potatoes. Cover the crockpot again and allow the cheese to melt, creating a rich, creamy topping.
Serve: Carefully remove the chicken and potatoes from the crockpot, using a slotted spoon to allow excess sauce to drain. Spoon some of the decadent creamy sauce from the bottom of the crockpot over the plated dish to enrich the flavors. Lastly, garnish with freshly chopped parsley for a pop of color and freshness.
Notes
