In a large deep skillet or saucepan, melt the butter over medium-high heat. Lower to medium heat and sprinkle with 1/4 cup flour. Whisk together until butter has absorbed the flour. Cook for 1 minute.
Whisking constantly, add the turkey stock gradually until fully blended. Whisk in turkey stock-flour mixture in a steady stream. Add salt, pepper, poultry seasoning and browning sauce.

Reheating Turkey Gravy: Place into a saucepan on the stove over low heat. Skim the fat from turkey pan drippings. Add pan drippings 1 Tbsp at a time to thin gravy. Repeat until your desired thickness is reached. Serve warm garnished with additional pepper and thyme, if desired.
How Do You Make Turkey Gravy Using Pan Drippings? You can use this same recipe to make gravy from the turkey pan drippings in the same amount. To do so, skim the fat and strain the pan drippings after baking the turkey. Use additional chicken stock, if needed, to equal the 32 ounces needed then proceed with the recipe as written. Adjust the seasonings to your taste according to how your baked turkey was seasoned.
