Using a sieve or a strainer of some sort, strain the turkey drippings. You will want to remove the majority of the solids while retaining the liquid.
Melt butter in a saucepan over medium heat.
Add in flour and whisk until slightly browned. Add in thyme, rosemary, and parsley. Whisk until incorporated.
Whisk turkey drippings into the gravy in batches. Whisk for 2-3 minutes.
Once gravy comes to a boil, reduce heat and continue to whisk until gravy has thickened to your desired consistency. Season with kosher salt and course black pepper to taste.
