Preheat oven to 400°F. Spray (1) 9×9-inch square baking dish with cooking spray. Set aside.
Melt butter in a large skillet. Saute vegetables until crisp-tender, about 5 minutes – they should be tender but still have a bit of a bite to them.
⅓ cup salted butter, 4 cups assorted diced vegetables
Sprinkle in the flour, salt, garlic powder and onion powder. Stir to coat all of the vegetables; cook 1 minute, stirring constantly. Gradually add the chicken broth and half-and-half; cook over medium heat, stirring constantly, until thick. Stir in the chicken. Taste for seasoning, adding additional salt or black pepper as desired. Pour the filling into the prepared baking dish.
½ cup flour, ½ teaspoon fine sea salt, ½ teaspoon garlic powder, ½ teaspoon onion powder, 1 ½ cups chicken broth, 1 ½ cups half-and-half, 1 ½ cups shredded rotisserie chicken
In a medium bowl, stir together the Bisquick and milk. Evenly dollop the topping over the top of the filling by the spoonful.
2 cups Bisquick baking mix, ⅔ cup whole milk
Bake for 35-40 minutes, or until the biscuit topping is golden and the filling is bubbly. Let rest for 5-10 minutes. Just before serving, brush the top of the Bisquick chicken pot pie with melted butter.
2 tablespoons salted butter
Notes
Good vegetables for pot pie include potatoes (regular or sweet), carrots, peas, corn, broccoli, onions, butternut squash, green beans, etc.
If using a combination of fresh and frozen vegetables, saute fresh vegetables according to the recipe. Thaw frozen vegetables and add at the end with the chicken. This will keep them from getting mushy.
Half-and-half is a mixture of milk and cream. If you don't have access to half-and-half, you can use 3/4 cup milk and 3/4 cup cream. You can also use all whole milk—the filling just won't be quite as creamy.
