Traditional gravy is not low carb. A single tablespoon of standard brown gravy contains about 3.4 grams of net carbs, which means a typical quarter-cup serving lands around 14 grams of net carbs. That’s a significant chunk of a daily carb budget for anyone on a keto or low-carb diet, and the culprit is almost always the flour used to thicken it.
Why Regular Gravy Is High in Carbs
The base of most gravies, whether brown gravy made from meat drippings or white country gravy made with milk, is a roux. A roux is equal parts flour and fat cooked together, and it’s the flour that drives the carb count up. All-purpose flour contains roughly 6 grams of net carbs per tablespoon, and most gravy recipes call for at least two tablespoons to thicken a batch. The liquid itself (stock, broth, or milk) adds a few more carbs on top of that.
White country gravy tends to be even higher in carbs than brown gravy. It starts with the same flour-based roux but uses whole milk as the liquid, adding the natural sugars (lactose) from dairy. A quarter-cup serving of sausage gravy can easily reach 8 to 10 grams of net carbs, sometimes more depending on the recipe.
Store-bought gravy packets and jarred gravies aren’t much better. Many contain added starches like cornstarch or modified food starch along with small amounts of sugar, keeping the carb count in the same range or higher than homemade versions.
How to Make Gravy Low Carb
The simplest fix is replacing the flour with a low-carb thickener. You have several good options, each with slightly different results.
- Xanthan gum is the most popular choice in keto cooking. It thickens powerfully in tiny amounts. Start with about 1/4 teaspoon per cup of liquid, whisking or blending it in slowly, then wait a minute before adding more. It clumps easily, so sprinkle it in rather than dumping it. The carb contribution is essentially zero at these quantities.
- Cream cheese whisked into hot drippings creates a rich, smooth gravy with a slightly tangy flavor. One ounce adds about 1 gram of carbs and gives the gravy body without any powdered thickener.
- Heavy cream reduction is the most hands-off method. Simmer pan drippings with heavy cream until it thickens naturally through evaporation. This takes longer (10 to 15 minutes of gentle bubbling) but produces a luxurious texture with minimal carbs.
- Egg yolks tempered into warm broth thicken gravy the way they thicken a custard. Whisk one yolk with a spoonful of warm broth first to prevent scrambling, then stir it into the pot. Each yolk adds less than 1 gram of carbs.
The base of your gravy matters too. Pure meat drippings, bone broth, and butter are all virtually zero-carb. If you start with those and skip the flour, a quarter-cup serving of homemade low-carb gravy can come in under 1 gram of net carbs.
Carb Counts for Common Gravy Types
To put things in perspective, here’s what a quarter-cup serving looks like across different styles:
- Flour-thickened brown gravy: approximately 13 to 14 grams of net carbs
- White country/sausage gravy: approximately 8 to 12 grams of net carbs
- Store-bought jarred gravy: approximately 5 to 8 grams of net carbs (varies by brand)
- Homemade keto gravy (xanthan gum or cream-based): under 1 gram of net carbs
Tips for Keto-Friendly Gravy
If you’re roasting meat, save every drop of the pan drippings. Those drippings are pure flavor with zero carbs, and they form the backbone of a great low-carb gravy without needing much else. Deglaze the roasting pan with a splash of broth, scrape up the browned bits, and you already have a thin sauce that just needs thickening.
When using xanthan gum, less is more. Too much creates a slimy, gummy texture that’s nothing like real gravy. Add it in small increments and give each addition 30 to 60 seconds to fully hydrate before judging the thickness. An immersion blender helps distribute it evenly and prevents clumps.
For the closest texture to traditional gravy, combine methods. A splash of heavy cream plus a pinch of xanthan gum gives you both the richness and the glossy consistency that makes gravy feel like gravy. Season generously with salt, pepper, and a touch of garlic, and most people at the table won’t notice the difference.
