When it comes to cooking a delicious meal in a slow cooker, one of the most important aspects is the gravy. A rich, thick, and flavorful gravy can elevate the entire dish, while a thin and watery one can be a letdown. If you’re struggling to thicken your slow cooker gravy, don’t worry, you’re not alone. In this article, we’ll explore the different methods for thickening gravy in a slow cooker, including the use of roux, cornstarch, flour, and other ingredients.
Understanding the Science of Thickening Gravy
Before we dive into the different methods for thickening gravy, it’s essential to understand the science behind it. Gravy is a liquid mixture of meat juices, broth, and seasonings. When you cook meat in a slow cooker, the connective tissues break down, releasing collagen and gelatin into the liquid. These proteins help to thicken the gravy, but they can also make it too thin and watery if there’s too much liquid.
The key to thickening gravy is to reduce the amount of liquid and increase the concentration of solids. This can be achieved by cooking the gravy for a longer period, reducing the heat, or adding thickening agents. The type of thickening agent you use will depend on the type of gravy you’re making and the desired consistency.
Roux: The Classic Thickening Agent
Roux is a mixture of flour and fat that’s used to thicken sauces and gravies. It’s a classic technique that’s been used for centuries, and it’s still one of the most effective methods for thickening slow cooker gravy. To make a roux, you’ll need to mix equal parts of flour and fat (such as butter or oil) in a pan. Cook the mixture over medium heat, stirring constantly, until it reaches the desired color.
There are different types of roux, including white, blond, and brown. The type of roux you use will depend on the type of gravy you’re making. A white roux is used for light-colored gravies, while a brown roux is used for darker gravies.
To use a roux to thicken your slow cooker gravy, simply mix it into the liquid and cook for an additional 30 minutes to 1 hour. The roux will help to thicken the gravy and add flavor.
Using Cornstarch as a Thickening Agent
Cornstarch is another popular thickening agent that’s commonly used in slow cooker recipes. It’s a starchy powder that’s derived from corn, and it’s gluten-free. To use cornstarch as a thickening agent, mix it with a small amount of cold water or broth until it forms a smooth paste. Then, add the paste to the slow cooker and cook for an additional 30 minutes to 1 hour.
One of the advantages of using cornstarch is that it’s easy to mix and doesn’t require cooking. However, it can leave a starchy flavor in the gravy if it’s not cooked long enough.
Using Flour as a Thickening Agent
Flour is another common thickening agent that’s used in slow cooker recipes. It’s a starchy powder that’s derived from wheat, and it’s often used in combination with fat or broth to thicken gravies. To use flour as a thickening agent, mix it with a small amount of cold water or broth until it forms a smooth paste. Then, add the paste to the slow cooker and cook for an additional 30 minutes to 1 hour.
One of the advantages of using flour is that it’s easy to mix and doesn’t require cooking. However, it can leave a starchy flavor in the gravy if it’s not cooked long enough.
Other Thickening Agents
There are other thickening agents that you can use to thicken your slow cooker gravy, including:
-
- Tapioca starch: This is a starchy powder that’s derived from cassava root. It’s gluten-free and has a neutral flavor.
- Potato starch: This is a starchy powder that’s derived from potatoes. It’s gluten-free and has a neutral flavor.
These thickening agents can be used in place of cornstarch or flour, and they’re often used in combination with other ingredients to thicken gravies.

What are the common methods for thickening gravy in a slow cooker?
There are several methods for thickening gravy in a slow cooker, including using cornstarch, flour, or tapioca starch as a slurry, adding a roux, or using a gravy thickener mix. You can also try reducing the liquid in the slow cooker by cooking it on high for a few hours or by simmering it on the stovetop. Additionally, you can add a little bit of butter or cream to enrich the flavor and thicken the gravy.
When choosing a method, consider the type of dish you are making and the desired consistency of the gravy. For example, if you are making a hearty beef stew, a thicker gravy may be more suitable, while a lighter gravy may be better for a chicken or vegetable dish. It’s also important to note that some methods may affect the flavor of the gravy, so you may need to adjust the seasoning accordingly.
How do I make a slurry to thicken my slow cooker gravy?
To make a slurry, mix 1-2 tablespoons of cornstarch, flour, or tapioca starch with a small amount of cold water or broth until smooth. The key is to mix the slurry well to avoid lumps, so make sure to stir it thoroughly before adding it to the slow cooker. You can also mix the slurry with a little bit of fat, such as butter or oil, to help it dissolve more easily.
Once you’ve made the slurry, add it to the slow cooker and stir to combine. Cook the gravy on high for about 30 minutes to allow the slurry to thicken. You can also simmer the gravy on the stovetop for a few minutes to speed up the thickening process. Be careful not to over-thicken the gravy, as it can become too thick and sticky.
Can I use flour to thicken my slow cooker gravy?
Yes, you can use flour to thicken your slow cooker gravy, but it’s best to mix it with a little bit of fat, such as butter or oil, to help it dissolve more easily. This is called making a roux, and it can add a rich, nutty flavor to the gravy. To make a roux, melt the butter or heat the oil in a pan, then gradually add the flour, whisking constantly to avoid lumps.
Once you’ve made the roux, cook it for a few minutes to allow the flour to cook and the mixture to darken slightly. Then, gradually add the liquid from the slow cooker, whisking constantly to avoid lumps. Bring the mixture to a boil, then reduce the heat and simmer for a few minutes to thicken the gravy.
How do I prevent lumps from forming when thickening my slow cooker gravy?
To prevent lumps from forming when thickening your slow cooker gravy, make sure to mix the slurry or roux well before adding it to the slow cooker. You can also whisk the gravy constantly as you add the thickening agent to help it dissolve evenly. If you do notice lumps forming, you can try whisking the gravy vigorously or straining it through a fine-mesh sieve to remove the lumps.
Another way to prevent lumps is to cook the gravy on low for a longer period of time, allowing the thickening agent to dissolve slowly and evenly. You can also try adding the thickening agent towards the end of the cooking time, so it has less time to form lumps.
Can I thicken my slow cooker gravy with cream or butter?
Yes, you can thicken your slow cooker gravy with cream or butter, but this method is best used in combination with another thickening agent, such as a slurry or roux. Adding a little bit of cream or butter can enrich the flavor and texture of the gravy, but it may not be enough to thicken it on its own.
To thicken your gravy with cream or butter, simply stir it in towards the end of the cooking time. You can also try simmering the gravy on the stovetop for a few minutes to allow the cream or butter to melt and thicken the gravy. Be careful not to add too much cream or butter, as it can make the gravy too rich and overpowering.
How do I thicken a clear broth-based gravy in a slow cooker?
Thickening a clear broth-based gravy in a slow cooker can be a bit more challenging than thickening a richer, more robust gravy. One method is to use a slurry made with cornstarch or tapioca starch, as these starches are more effective at thickening clear liquids. You can also try reducing the liquid in the slow cooker by cooking it on high for a few hours or by simmering it on the stovetop.
Another method is to add a little bit of gelatin to the gravy, which can help to thicken it without affecting the flavor. Simply dissolve the gelatin in a little bit of hot water, then add it to the slow cooker and stir to combine. Cook the gravy on low for a few hours to allow the gelatin to thicken.
Can I thicken my slow cooker gravy ahead of time?
Yes, you can thicken your slow cooker gravy ahead of time, but it’s best to do so just before serving. If you thicken the gravy too far in advance, it may become too thick and sticky, or it may separate and lose its texture. To thicken the gravy ahead of time, simply prepare the slurry or roux, then refrigerate or freeze it until you’re ready to use it.
When you’re ready to serve, simply stir the thickening agent into the slow cooker and cook on high for a few minutes to allow it to thicken. You can also simmer the gravy on the stovetop for a few minutes to speed up the thickening process. Be careful not to over-thicken the gravy, as it can become too thick and sticky.
