Make sure you have enough turkey drippings + stock to equal about 4 cups. If you don’t have enough turkey drippings, add chicken broth to total 4 cups.

Add butter to a large skillet over medium high heat. Once melted, whisk in a bit of flour, then slowly add in the drippings/stock alternately with the flour, whisking to avoid lumps.

Bring the gravy to a simmer and allow it to thicken for a minute or two, stirring occasionally. Add more stock if necessary to thin. Taste and adjust salt and pepper as needed, and add herbs if desired.
