Step 4: Add the Cheese and Bake - Sprinkle the mozzarella evenly over the cranberry layer, followed by the shredded cheddar. Try to spread the cheese from edge to edge rather than leaving a big mound in the center. Place the baking dish into the preheated oven and bake uncovered for about 35 to 40 minutes. Cooking time will depend on the thickness of your chicken, so use an
instant read thermometer rather than relying only on the clock. The chicken is ready when the thickest portion reaches an internal temperature of 165°F. By then the cheese should be melted and the cranberry mixture should be hot and glossy around the edges.
