While the Thanksgiving turkey is being carved, you'll find me, whisk in hand, making pan gravy at the stove right from the roasting pan. I never use premade gravy because I think it tastes awful compared to a fresh pan gravy. Besides, pan gravy is a pretty fast & easy process. Flour, cornstarch or arrowroot flour are traditionally added to pan drippings to thicken your gravy, but these have 6 to 7 grams of carbs per tablespoon. A keto-friendly alternative is to use guar gum. Make sure you have your guar gum on hand before your holiday in order to make a low-carb pan gravy.
Guar gum is made from the Guar bean which grows in India. It has been extensively tested for safety in animals. Studies have shown that it's consumption is associated with lowered body weight and blood glucose, all of which is ideal on a ketogenic diet! (1) Guar gum is a soluble fiber so the nutritional label lists 9 grams of carbohydrate per tablespoon, but it is all fiber, so those carbohydrates are essentially unused by the body, making it a natural carb-free thickening agent for gravy.
You'll use about 1 tsp. or more of guar gum per cup of gravy, depending on how thick you like it.
My best tips for gravy are to not worry about it having little bits of turkey in it or straining it to make perfectly smooth. No one cares, they only want to eat it when it's hot. Also, I prefer to serve my gravy in a warmed covered bowl set on a plate with a ladle. This way, your gravy stays warm by the time you get to your second helping.
