I heat the oven to 375°F and lightly grease a 9-by-13-inch baking dish.

I stir together the chicken, soup, broth, milk, vegetables, thyme, salt, and pepper in the dish.

I cut the biscuit dough into small pieces and scatter them across the top.

I bake for 35 to 40 minutes, until the filling bubbles and the dumplings turn golden. I let it rest for 5 minutes before serving.
