1/2 cup reserved turkey pan drippings (optional, if using drippings)
1 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon dried poultry seasoning
Instructions
If using drippings, skim off any excess fat from the drippings and measure out 1/2 cup. Set aside.
In a large saucepan, melt the butter over medium heat.
Whisk in the flour to create a smooth paste, called a roux. Cook the roux for 2 to 3 minutes, stirring constantly, until it smells slightly nutty. Do not let it brown.
If using drippings, whisk the reserved 1/2 cup of warm drippings into the roux until fully incorporated.
Gradually whisk in the turkey stock, a little at a time, ensuring no lumps form before adding more liquid.
Bring the mixture to a simmer, stirring frequently. Reduce the heat to low and let it cook for 5 to 10 minutes, or until the gravy thickens enough to coat the back of a spoon.
Stir in the salt, pepper, and poultry seasoning. Taste and adjust seasoning as needed.
For a smoother gravy, strain it through a fine-mesh sieve before serving.
To make ahead: Cool the gravy completely, then store it in an airtight container in the refrigerator for up to 3 days or freeze for up to 1 month. Reheat gently on the stovetop, whisking in a splash of stock or water if it becomes too thick.
Notes
For extra flavor when using stock only, add 1 teaspoon of Worcestershire sauce or a splash of dry sherry while simmering.
If the gravy is too thin after simmering, create a slurry by mixing 1 teaspoon of cornstarch with 2 teaspoons of cold water. Whisk this into the simmering gravy until thickened.
If the gravy is too thick, whisk in warm stock or water until you reach your desired consistency.
