1-First Step: Preheat Oven and Prepare Ingredients Preheat your oven to 350°F (175°C). Gather all ingredients, shred or chop the cooked chicken, and have frozen vegetables ready. Melt 4 tablespoons of salted butter for greasing the dish.

2-Second Step: Grease Dish and Layer Filling Pour melted butter evenly into the bottom of a 9×13-inch baking dish to prevent sticking and add richness. Spread the shredded chicken in an even layer over the butter. Then, spread the frozen peas and carrots or mixed veggies evenly over the chicken without mixing.

3-Third Step: Make and Add Sauce In a separate bowl, whisk together the cream of chicken soup, chicken broth, garlic powder, onion powder, and black pepper until smooth and uniform. Pour this creamy mixture evenly over the chicken and vegetable layers without stirring.

4-Fourth Step: Prepare Biscuit Topping Clean the mixing bowl, then combine the biscuit mix (without seasoning packet), 2 cups of milk, and shredded cheddar cheese. Stir gently until fully combined to form a batter. Spread the biscuit batter carefully over the filling layers, covering them completely without mixing.

5-Fifth Step: Add Seasoned Butter Topping Mix the reserved biscuit mix seasoning packet with 2 tablespoons of melted butter. Brush this seasoned butter evenly over the biscuit topping to enhance flavor and promote a golden crust during baking.

6-Final Step: Bake and Rest Bake the cobbler uncovered for 50 to 60 minutes, until the biscuit topping is golden brown and the casserole is bubbling. Oven times may vary, so start checking around 50 minutes. Remove from oven and let the cobbler rest for at least 10 minutes to allow the filling to thicken and flavors to develop before serving.
