First Step: Preheat oven and prepare baking dish Set your oven to 350-375°F (175-190°C). Grease a 9×13-inch baking dish to prevent sticking and to help with even baking.

Second Step: Melt butter and layer base Pour 4 tablespoons of melted salted butter evenly across the bottom of the baking dish. Do not stir, as this forms a flavorful base for the cobbler.

Third Step: Add chicken and vegetable layers Evenly layer the shredded or chopped rotisserie chicken over the melted butter. Then, sprinkle the frozen peas and carrots or your choice of mixed vegetables uniformly on top of the chicken.

Fourth Step: Make and pour sauce In a separate bowl, whisk together the cream of chicken soup, chicken broth, garlic powder, onion powder, and black pepper until smooth. Pour this mixture evenly over the chicken and vegetables without stirring, so each layer remains distinct.

Fifth Step: Prepare the biscuit topping In a clean bowl, combine the biscuit mix (reserve the seasoning packet), milk, and shredded cheddar cheese if using. Stir gently until just blended; avoid overmixing to maintain biscuit fluffiness.

Sixth Step: Assemble and bake Spread the biscuit mixture evenly over the sauce layer in the baking dish. Bake uncovered for 50-65 minutes until you see bubbling filling and the biscuit topping becomes golden brown and fully cooked.

Final Step: Finish with butter topping and rest Remove the cobbler from the oven. Mix 2 tablespoons melted butter with the reserved seasoning packet and brush this mixture evenly over the biscuit crust. Optionally, sprinkle chopped parsley for added flavor and color. Let the cobbler rest for 10-15 minutes before serving to thicken the filling and meld flavors.
