Preheat oven to 375°F and grease a 9×13 baking dish.
In a big bowl, whisk 1 cup milk, ½ cup heavy cream, ½ cup sour cream, 1 can cream of chicken soup, and 1 cup chicken broth until smooth.
Stir in 1 tsp garlic powder, ½ tsp salt, ½ tsp black pepper, 2 cups frozen or fresh mixed veggies, half a cup of shredded cheddar cheese, and your cooked shredded chicken. Mix well.
Pour that creamy chicken mixture into the prepared dish and spread it out.
In another bowl, prepare the Cheddar Bay biscuit mix per package directions.
Drop spoonfuls of the biscuit dough evenly over the chicken filling.
Drizzle melted butter over the biscuits and sprinkle with parsley if you’re feeling fancy.
Bake 40–45 minutes, until the biscuits are golden and the filling is bubbly.
(If biscuits are browning too fast, cover with foil for the last 10 minutes)
Enjoy!
