Preheat your oven to 375 degrees fahrenheit. Spray a muffin tin with non-stick spray, set aside.
In a 2-quart sauce pan, heat butter over medium heat, until melted.
Whisk in flour, until well combined. Cook for 1-2 minutes.
Stir in seasonings.
Slowly whisk in the chicken broth, followed by the milk, cook over medium, stirring frequently, until it begins to thicken.
Add in cooked chicken and vegetables, stir to combine. Continue cooking until mixture is heated through.
Remove from the heat and roll your crescent dough out onto a large cutting board.
Press together the seams of the crescent rolls, then cut the dough evenly into 8 squares.
Take each square and press down into your prepared muffin tin.
Add spoonfuls of the pot pie mixture evenly to each cup. If you have extra mixture, you can freeze it for another batch of cups. To thaw later, heat in a saucepan on medium-low until heated through.
Bake for 16-18 minutes until crescent rolls are golden brown.
Cool for 5 minutes, then remove your crescent chicken pot pie cups from the muffin tins.
