First, I combined the seasoning packet, hot water, and butter in a large bowl. Letting it sit a few minutes helps the crumbs absorb flavor and become perfectly moist before baking.
Next, I preheated my oven to 375°F (190°C) and placed the chicken breasts in the baking dish. I mixed the condensed soup with milk, then poured this creamy sauce over the chicken. This step ensures the meat stays juicy as it cooks.
Finally, I spooned portions of the prepared stuffing mix over and around the chicken, then baked the dish for about 35 minutes. When it was done, the chicken was tender and the stuffing had soaked up all the savory juices.
