Remove the cooked turkey from the roasting pan.
Remove any large chunk of impurity from the pan if you want super creamy gravy at the end.
Place the roasting pan on the stovetop over medium-high heat. Add the unsalted butter to the pan, wait until the butter melts completely, and then add the minced shallot.
Stir the pan constantly to prevent it from burning and scorching. Cook the minced shallot for 2 minutes.
Deglaze the pan using turkey stock. Add ground black pepper then bring the mixture to a simmer. Then simmer it for 5 minutes.
Constantly stir the mixture with a spoon or spatula; don't forget to stir the corners of the pan too.
Then, thicken the liquid with heavy whipping cream.
Simmer the gravy until the mixture reduces by ⅓, approximately 5-7 minutes. Do not boil, or the gravy will separate or break.
The turkey gravy is done cooking when it has a consistency that will coat the back of a spoon.
Serve the gravy warm over or as a side to roasted turkey meat.
