Gravy, the luscious, savory sauce that elevates everything from Thanksgiving turkey to humble biscuits, is a kitchen staple. But achieving the perfect gravy consistency can sometimes feel like a culinary tightrope walk. Too thin, and it’s watery; too thick, and it’s gluey. The secret often lies in the thickening agent, and cornstarch is a readily available option. But can you really use cornstarch for gravy? The answer is a resounding yes, but there’s more to it than simply dumping a spoonful into your pan drippings. Let’s explore the nuances of using cornstarch for gravy, ensuring you achieve gravy nirvana every time.
Understanding the Role of a Thickening Agent
Before diving into the specifics of cornstarch, let’s understand why thickening agents are essential in gravy. Gravy, at its core, is a liquid – typically broth, stock, or pan drippings – flavored with rendered fat and seasonings. Without a thickening agent, this liquid would remain just that: liquid. The thickener is responsible for binding the liquid together, creating that characteristic velvety texture we all crave. Different thickening agents achieve this effect in slightly different ways, influencing the final flavor, appearance, and stability of the gravy.
Common Thickening Agents Compared
While cornstarch is a popular choice, it’s not the only option. Understanding the alternatives allows you to make informed decisions based on your preferences and available ingredients. Flour, arrowroot, tapioca starch, and even potato starch are viable alternatives, each with its own set of pros and cons.
Flour, for example, is a traditional choice, but it requires more cooking time to eliminate its raw flour taste. It also tends to produce a slightly opaque gravy. Arrowroot, on the other hand, creates a clear, glossy gravy but can be sensitive to high heat and acidity. Tapioca starch offers a similar clarity to arrowroot and is more stable, but it can sometimes create a slightly stringy texture. Potato starch is another option, known for its strong thickening power, but it can also become gummy if overcooked.
Why Choose Cornstarch for Gravy?
Cornstarch has several advantages that make it a compelling choice for thickening gravy.
-
Purity of Flavor: Cornstarch boasts a neutral flavor profile. This means it won’t impart any unwanted tastes to your gravy, allowing the other flavors to shine through. This is particularly important when you’re working with delicate stocks or pan drippings that you want to highlight.
-
Potent Thickening Power: Cornstarch has impressive thickening power compared to flour. A smaller amount of cornstarch is needed to achieve the same level of thickness, reducing the risk of a starchy or gummy texture.
-
Creates a Glossy Finish: Gravy thickened with cornstarch typically has a glossy, appealing sheen. This visual appeal can significantly enhance the overall dining experience.
-
Gluten-Free Option: For those with gluten sensitivities or allergies, cornstarch provides a naturally gluten-free alternative to flour-based gravies.
Mastering the Cornstarch Slurry: The Key to Success
The single most important aspect of using cornstarch for gravy is creating a cornstarch slurry. A slurry is simply a mixture of cornstarch and cold water (or other cold liquid) that is whisked together until smooth. This is crucial because adding dry cornstarch directly to hot liquid will almost certainly result in clumps.
Why a Slurry is Essential
Dry cornstarch has a tendency to clump together when exposed to heat. These clumps are difficult to dissolve and can leave your gravy with an unpleasant lumpy texture. By creating a slurry, you pre-disperse the cornstarch granules, ensuring they hydrate evenly when added to the hot liquid.
The Perfect Slurry Ratio
A good rule of thumb is to use a 1:1 ratio of cornstarch to cold water. For example, 1 tablespoon of cornstarch mixed with 1 tablespoon of cold water. Adjust the amount depending on the desired thickness of your gravy.
Making the Slurry: A Step-by-Step Guide
- In a small bowl, combine the cornstarch and cold water.
- Whisk vigorously until the mixture is completely smooth and lump-free. Ensure there’s no cornstarch settled at the bottom of the bowl.
- Set aside until ready to use.
Adding the Slurry to Your Gravy: Timing is Everything
The timing of adding the cornstarch slurry is crucial for achieving the desired consistency without overcooking or compromising the flavor.
When to Add the Slurry
Wait until your gravy is almost at its desired thickness before adding the slurry. This means that you should have already deglazed the pan (if applicable), added your broth or stock, and brought the mixture to a simmer.
How to Incorporate the Slurry
- Bring the gravy to a gentle simmer.
- Whisk the cornstarch slurry again to ensure it’s smooth. Cornstarch can settle at the bottom while sitting.
- Slowly drizzle the slurry into the simmering gravy, whisking constantly.
- Continue whisking until the gravy thickens to your desired consistency. This should only take a minute or two.
Preventing Lumps: The Importance of Constant Whisking
The key to preventing lumps when adding the slurry is constant whisking. This ensures that the cornstarch granules are evenly distributed and don’t clump together.
Troubleshooting Common Cornstarch Gravy Problems
Even with careful preparation, things can sometimes go awry. Here’s how to troubleshoot some common cornstarch gravy problems.
Lumpy Gravy: Salvaging the Situation
If your gravy becomes lumpy, don’t despair! There are a few ways to salvage it.
- Strain it: Pour the gravy through a fine-mesh sieve to remove the lumps. This is the quickest and easiest solution.
- Use an immersion blender: Carefully use an immersion blender to blend the gravy until smooth. Be cautious not to over-blend, as this can make the gravy gummy.
- Whisk Vigorously: Remove from the heat and whisk vigorously. Sometimes the lumps will simply dissolve back into the gravy with enough elbow grease.
Thin Gravy: Adding More Thickness
If your gravy isn’t thick enough after adding the initial slurry, you can easily add more. Simply mix another small batch of slurry and slowly whisk it into the simmering gravy until you reach the desired consistency.
Gummy Gravy: Avoiding Overcooking
Overcooking cornstarch gravy can result in a gummy or gluey texture. To avoid this, remove the gravy from the heat as soon as it reaches your desired thickness. Cornstarch continues to thicken as it cools, so it’s better to err on the side of slightly thinner than to overcook it.
Watery Gravy: Too Much Liquid
If you’ve added too much liquid to your gravy, you have a few options. You can either simmer the gravy uncovered to reduce the liquid, or you can add more cornstarch slurry to thicken it.
Tips for Achieving Gravy Perfection with Cornstarch
-
Use Cold Liquid for the Slurry: Always use cold water, stock, or broth to create the cornstarch slurry. Hot liquid will cause the cornstarch to clump.
-
Whisk Constantly: Constant whisking is essential throughout the process, from creating the slurry to incorporating it into the gravy.
-
Simmer Gently: Avoid boiling the gravy vigorously after adding the slurry. A gentle simmer is all that’s needed to activate the cornstarch.
-
Taste and Adjust Seasoning: Always taste your gravy and adjust the seasoning as needed. Salt, pepper, and other herbs and spices can enhance the flavor significantly.
-
Use High-Quality Ingredients: The quality of your ingredients will directly impact the flavor of your gravy. Use high-quality stock, broth, or pan drippings for the best results.
-
Don’t Overcook: Overcooking cornstarch gravy can result in a gummy texture. Remove it from the heat as soon as it reaches your desired consistency.

Can I use cornstarch to thicken gravy?
Yes, you absolutely can use cornstarch to thicken gravy. Cornstarch is a very effective and popular thickening agent, especially valued for its ability to create a clear, glossy gravy. It works by absorbing liquid and swelling when heated, forming a gel-like structure that thickens the gravy to your desired consistency.
However, remember to use it properly to avoid lumps. You should always mix cornstarch with a cold liquid (usually water or broth) to create a slurry before adding it to the hot gravy. This prevents the cornstarch granules from clumping together when they come into contact with the heat, ensuring a smooth and delicious result.
How much cornstarch should I use to thicken my gravy?
The amount of cornstarch needed depends on how thick you want your gravy and the amount of liquid you’re starting with. A general guideline is to use about 1 tablespoon of cornstarch for every cup of liquid in your gravy. This will typically result in a medium-thick gravy.
For a thinner gravy, start with half a tablespoon per cup, and for a thicker gravy, increase the amount to 1.5 or even 2 tablespoons per cup. Always add the cornstarch slurry gradually, stirring constantly, and allow the gravy to simmer for a minute or two after each addition to assess the thickness and avoid over-thickening.
What are the pros and cons of using cornstarch for gravy?
One of the biggest advantages of using cornstarch is that it creates a clear, glossy gravy, unlike flour which can make it opaque. It’s also a gluten-free option, making it suitable for people with gluten sensitivities or celiac disease. Furthermore, cornstarch thickens quickly and effectively, requiring only a short simmering time.
However, cornstarch can be less stable than flour when exposed to prolonged heat or acidic ingredients. Overcooking or adding acidic elements like lemon juice or vinegar in excess can cause the gravy to thin out again. Also, gravy thickened with cornstarch doesn’t reheat as well as gravy thickened with flour, sometimes becoming watery.
How do I make a cornstarch slurry for gravy?
Creating a cornstarch slurry is a crucial step in using cornstarch for gravy. To do this, simply combine cold water (or broth) and cornstarch in a small bowl. The goal is to create a smooth, lump-free mixture that can be easily incorporated into the gravy without clumping.
A good ratio is about 1 tablespoon of cornstarch to 2 tablespoons of cold liquid. Whisk the mixture thoroughly until the cornstarch is fully dissolved and no lumps remain. This slurry is then ready to be added to your simmering gravy, stirring constantly to ensure even thickening.
What happens if I add cornstarch directly to hot gravy?
Adding cornstarch directly to hot gravy is a recipe for disaster, literally. When dry cornstarch comes into contact with hot liquid, the granules immediately clump together, forming stubborn lumps that are very difficult to break down. These lumps will ruin the texture of your gravy, making it unpleasant to eat.
Even vigorous stirring won’t eliminate these lumps effectively. The best way to prevent this issue is to always mix the cornstarch with cold liquid first to create a slurry. This ensures that the cornstarch granules are evenly dispersed and can thicken the gravy smoothly without clumping.
Can I use other starches besides cornstarch for gravy?
Yes, you can definitely use other starches besides cornstarch to thicken gravy, although the results may vary slightly. Common alternatives include arrowroot powder, tapioca starch, and potato starch. Each starch has its own unique properties and thickening power.
Arrowroot is a good substitute for cornstarch as it also creates a clear, glossy gravy. Tapioca starch can be used, but it can sometimes make the gravy a bit stringy. Potato starch has a strong thickening power, so you might need to use slightly less than you would cornstarch. Experimenting with different starches can allow you to find the best option for your specific needs and preferences.
How do I fix gravy that is too thick after using cornstarch?
If your gravy has become too thick after adding cornstarch, don’t panic! The easiest way to fix it is to gradually add more liquid. Use the same liquid that you used to make the gravy, whether it’s water, broth, or pan drippings.
Add the liquid a tablespoon at a time, stirring constantly, until the gravy reaches your desired consistency. Allow the gravy to simmer gently for a minute or two after each addition to assess the thickness and ensure the additional liquid is fully incorporated.
