Melt butter in a heavy-bottomed saucepan over medium heat for about 1 minute until it stops foaming. Watch it carefully—I once turned my back for 30 seconds and nearly burned mine. The moment it settles and smells nutty, you're ready for the next step.
Whisk the flour into the melted butter, stirring constantly for 2-3 minutes to cook out the raw flour taste. This roux should look like wet sand and smell slightly toasted, never burnt. You're building the thickening base here, so don't rush it or skip it.

Add the water, salt, black pepper, dried sage, dried thyme, onion powder, and garlic powder all at once. Stir well and bring the whole thing to a gentle simmer over medium heat. You're not looking for a rolling boil here because that breaks down the delicate balance you just created.
Let the turkey gravy crowd Thanksgiving easy recipe simmer for 8-10 minutes, stirring occasionally, so all those dried herbs release their flavor into the sauce. Taste it now and adjust seasoning if needed—this is your honest assessment moment before the final step. I usually add an extra 1/4 teaspoon of salt here because the stock itself varies in saltiness.
Mix 2 tablespoons of cornstarch with 3 tablespoons of cold water in a small bowl, stirring until completely smooth. Pour this slurry into the simmering gravy while whisking constantly for 1-2 minutes until it thickens to your preferred consistency. The cornstarch catches any remaining lumps and gives you the pourable-but-coats-the-spoon texture everyone expects.
Taste again and add fresh parsley just before serving, stirring it in gently. This final touch adds brightness and signals to everyone at the table that attention went into this sauce. Strain through a fine mesh if you're the type who prefers zero texture, though honestly, the herbs add character.
