Preheat your oven to 375°F (190°C). This temperature ensures that the casserole bakes evenly, creating perfectly fluffy dumplings while keeping the chicken moist and tender.
Step 2: Prepare the Chicken
Pull the meat from the rotisserie chicken, discarding the skin. Spread the shredded chicken evenly in a 9×13-inch baking dish. This provides a flavorful base for the casserole and ensures that every bite has plenty of chicken.
Step 3: Add the Butter
Pour the melted butter evenly over the chicken. The butter helps to flavor the chicken and contributes to the richness of the sauce and dumplings as they bake.
Step 4: Season
Season the chicken with a little salt and pepper. Adjust the seasoning to your taste, but keep in mind that the cream of chicken soup and broth will add additional flavor.
Step 5: Mix the Flour and Milk
In a medium-sized bowl, whisk together the self-rising flour and milk until smooth. This mixture will help create the dumplings as it bakes. Pour this mixture slowly and evenly over the chicken, making sure not to stir. The flour will settle on top and form the dumplings as the casserole cooks.
Step 6: Prepare the Broth Mixture
In the same bowl, whisk together the chicken broth and the condensed cream of chicken soup. Slowly pour this mixture over the chicken and flour, again avoiding stirring. The liquids will combine and create a creamy sauce as the casserole bakes.
Step 7: Bake the Casserole
Bake the casserole uncovered in the preheated oven for 45 minutes, or until the top is golden brown and the dumplings have formed. The casserole should be bubbling around the edges, and the dumplings should be firm but fluffy.
