After roasting your turkey, pour the pan drippings into a measuring cup or bowl. Skim off excess fat (save some for flavor if desired) and remove any large pieces of herbs, vegetables, or meat.
In a medium saucepan, melt butter and flour over medium heat. Whisk constantly for 2–3 minutes until the mixture turns golden, starts to bubble, and smells nutty.
Slowly whisk in 2 cups of chicken bone broth until smooth and lump-free.
Add in thyme leaves and simmer on low for 5 minutes, stirring occasionally.
Pour in the turkey drippings gradually, whisking constantly to incorporate.
Bring gravy to a gentle simmer for 8–10 minutes, stirring frequently until thickened.
Add salt and pepper to taste.
If the gravy is too thick, whisk in drippings if available (otherwise use more bone broth).
Keep warm until ready to serve over turkey, mashed potatoes, or stuffing.
