4tbsp.all-purpose flour, or gluten-free flour, see notes
1 tsp.powdered or granulated onion
1/2tsp.kosher salt
1/2tsp.white pepper or black pepper
2tsp.ground sage, (optional, *see note #2)
Instructions
In a high-sided skillet or saucepan, melt the butter on medium heat. Then, add the flour and use a whisk to fully coat the flour with butter and make a smooth paste. Allow this to cook while stirring for 1 minute or more to cook off the flour taste.
Add about 1/2 cup of the broth while whisking fairly rapidly to dissolve the flour into the liquid. Once all or most of the flour paste is incorporated, add the remainder of the broth. Continue to gently whisk the gravy and bring it to a boil then lower the heat to a simmer.
Add the spices and stir them into the gravy. Cook for an additional 3 to 4 minutes. Taste the gravy and adjust the seasonings as desired. Serve hot.
Notes
For gluten-free gravy, you may also use corn starch as a thickener. Heat 2 cups of broth in a saucepan, then mix 2.5 to 3 tablespoons of cornstarch with 3 or 4 tablespoons of cold water to make a slurry. Stir the slurry into the hot broth and allow the gravy to thicken. No butter is needed for this method except to add it for richness of flavor. Add desired seasonings.
Since I have made this gravy recipe numerous times, the addition of ground sage takes the gravy to more of a holiday flavor which is quite pleasing.
Store leftover gravy refrigerated in an airtight container for up to 2 days. You may freeze leftovers in an airtight container or freezer bag for up to 4 months. When cornstarch gravy is frozen it may lose some of its thickening power. If it seems too thin when reheated, just add a bit more cornstarch slurry.
Lots of different seasonings can be used for the gravy. When experimenting with seasonings start by adding small amounts and then tasting. It is easy to add more if desired.
