Is Gravy Gluten-Free?

From The New Day Notebook · Facts last checked October 21, 2026 · General information, not medical advice

Most gravy is not gluten-free. The key ingredient that determines if gravy contains gluten is the thickener, and traditional recipes usually use wheat flour to create a rich, smooth sauce.

However, finding or making a gluten-free gravy is straightforward. Many products use alternative thickeners, and safe preparation is a matter of choosing the right ingredients and avoiding cross-contact in the kitchen. The answer depends entirely on how the gravy was made and what is in the specific product.

Gravy and gluten at a glance

Why gravy usually contains gluten

The primary source of gluten in gravy is its thickening agent. A classic gravy starts with a roux, which is a paste made from fat and wheat flour. This base gives the gravy its characteristic texture and flavor. Because wheat is a primary source of gluten, any gravy made with a traditional roux will not be gluten-free.

Many prepared sauces and gravies, including mixes sold in packets and jars, also rely on wheat flour as a thickener. Reading the ingredients list is the only way to know for sure. A product explicitly labeled gluten-free has been verified to meet the FDA standard of containing less than 20 parts per million of gluten.

Where to check for gluten in gravy

Since gravy is so common, it is important to be mindful in several situations. You should always verify the ingredients in gravy served at restaurants or during holiday gatherings. A simple question about how the gravy was thickened can prevent accidental gluten exposure.

Be especially careful with shared food situations, like potlucks or buffets, where cross-contact is a risk. For example, a spoon used for a gluten-containing dish could be dipped into a gluten-free gravy. When eating out, it is also good practice to ask about shared fryers if you are ordering something like french fries that might be served with gravy.

Gluten-free gravy alternatives

Making delicious, thick gravy without gluten is simple. The key is to use a different starch for the thickener. Several alternatives work well:

• Cornstarch: Creates a glossy, smooth gravy. It is a very common and reliable thickener.
• Potato starch: Works similarly to cornstarch and is another popular choice for gluten-free sauces.
• Arrowroot: This starch also produces a clear, glossy finish and holds up well.

When making your own gravy, start with pan drippings for flavor and use a gluten-free broth. Instead of making a flour-based roux, you can mix your chosen starch with a small amount of cold liquid to make a slurry. Whisk the slurry into your simmering liquid until it reaches the desired thickness. This method completely avoids wheat and results in a gluten-free gravy.

When to loop in your doctor or dietitian

For people with celiac disease, a strict, lifelong gluten-free diet is the only treatment. If you are considering a gluten-free diet or have questions about hidden gluten in sauces and prepared foods, talk to your doctor or a registered dietitian. Do not begin a gluten-free diet before completing medical testing for celiac disease, as the tests require gluten to be present in your system to be accurate.

• If you think gluten is making you unwell, ask about celiac disease testing before cutting gluten out: testing needs gluten in the diet
• If you have celiac disease and still have symptoms on a gluten-free diet
• If you are unsure whether oats, wheat starch or a specific ingredient suits you
• For help planning a gluten-free diet that still meets your nutrition needs
