Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or casserole dish with butter or nonstick spray to prevent sticking.

Step 2: Prepare the Chicken

1. Pat the chicken pieces dry with paper towels. This helps the skin crisp up during baking.
2. Season both sides of the chicken with salt, black pepper, garlic powder, and paprika. Ensure the seasoning is evenly distributed for maximum flavor.

Step 3: Make the Creamy Sauce

1. In a medium mixing bowl, combine the heavy cream, chicken broth, sour cream, Dijon mustard (if using), thyme, onion powder, smoked paprika, and flour. Whisk until smooth and well-combined.
2. Taste the sauce and adjust seasoning as needed. Add a pinch of salt or extra paprika for a deeper flavor.

Step 4: Assemble the Dish

1. Arrange the seasoned chicken pieces in the prepared baking dish, skin-side up. Make sure the chicken pieces are evenly spaced to ensure even cooking.
2. Pour the creamy sauce evenly over the chicken, ensuring each piece is well-coated. The sauce will keep the chicken moist as it bakes.

Step 5: Bake the Chicken

1. Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes.
2. Remove the foil and bake uncovered for an additional 20 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the skin is golden brown.

Step 6: Garnish and Serve

1. Once the chicken is done, remove it from the oven and let it rest for 5 minutes. This allows the juices to redistribute, ensuring tender meat.
2. Garnish with chopped fresh parsley and a sprinkle of smoked paprika for added color and flavor.
3. Serve warm with your choice of side dishes, spooning extra sauce over the chicken for a rich, creamy finish.
