Prepare the Oven and Baking Dish: Begin by preheating your oven to 350°F (175°C). Take a 9x13-inch baking pan and lightly mist it with non-stick cooking spray.

Create the Soup Mixture: In a bowl, whisk together the condensed cream of chicken soup, milk, and shredded cheddar cheese until smooth. Set it aside for later.

Prepare the Crescents: Unroll the crescent roll dough, separating it into 8 individual triangles. At the broader end of each triangle, place a generous portion of the cooked chicken. Spoon a teaspoon of the soup mixture over the chicken on each triangle. Carefully roll the dough around the chicken, starting from the wide end and working your way to the tip.

Assemble in Baking Dish: Spread about 1/3 cup of the remaining soup mixture evenly across the bottom of the prepared baking dish. Position the filled and rolled crescents in the dish. Pour the rest of the soup mixture over the top, ensuring they're nicely coated.

Bake to Perfection: Place the baking dish in the preheated oven, allowing the rolls to bake for approximately 30 minutes, or until they become bubbly and golden brown on top.

Serve and Enjoy: Once done, remove from the oven and allow to cool slightly before serving. Enjoy the delicious blend of flavors wrapped inside these warm crescent rolls.
