You make homemade turkey gravy with defatted turkey drippings, butter, onion, heavy cream and a few additional ingredients. This recipe takes about 30 minutes to prepare and makes 3 cups of gravy.
To make the turkey gravy, start by sautéing 1 stick of unsalted butter and 1 1/2 cups chopped yellow onions in a saucepan over medium-low heat for 12 to 15 minutes or until the onions start to soften. Take your time with this part because it is important that the onions cook until they start to brown.
Next, sprinkle 1/4 cup of flour into the pan, stirring the flour into the butter and onions, and then add in 1 teaspoon kosher salt and 1/2 teaspoon freshly ground black pepper. Cook this mixture for about 3 minutes before heating up the turkey drippings with 2 cups of chicken stock. Once this mixture heats up, add the chicken stock to the butter mixture followed by 1 tablespoon of Cognac. Let this cook uncovered for about five minutes until it begins to thicken. Pour in 1 tablespoon of white wine and 1 tablespoon of heavy cream if you desire, and the gravy is then ready to serve.
This recipe is easy to double or triple. If you don't have turkey fat, you can use 1 cup of chicken stock and 1 cup of beef stock instead.
