Gravy, the savory nectar that transforms a simple meal into a culinary masterpiece. Whether it’s drizzled over roasted turkey, mashed potatoes, or biscuits, a perfectly thickened gravy is the hallmark of a skilled cook. But achieving that ideal consistency can be tricky. Choosing the wrong thickener can lead to a lumpy, gluey, or thin disaster. Fear not, aspiring gravy gurus! This comprehensive guide will explore the best gravy thickeners, their strengths, weaknesses, and how to use them effectively, ensuring your gravy is always a triumph.
Understanding the Science of Thickening
Before diving into the specific thickeners, let’s understand the science behind the magic. Thickening occurs when starch granules absorb liquid and swell, creating a viscous consistency. This process, called gelatinization, is influenced by factors like temperature, the type of starch, and the presence of other ingredients like fat and acid.
The Importance of Proper Hydration and Dispersion
The key to smooth gravy lies in ensuring the thickening agent is properly hydrated and dispersed before it’s added to the hot liquid. Clumps form when starch granules stick together before they’ve had a chance to absorb liquid individually. This is why many thickeners are mixed with cold water to create a slurry or roux before being incorporated into the gravy.
The Contenders: Exploring Common Gravy Thickeners
Now, let’s explore the most popular gravy thickeners, examining their pros, cons, and optimal uses. We’ll delve into the world of flour, cornstarch, arrowroot, tapioca starch, potato starch, and even some unconventional options.
Flour: The Classic Choice
Flour is the traditional and arguably most widely used gravy thickener. Its appeal lies in its accessibility and its ability to contribute not only thickness but also flavor.
Using flour involves creating a roux, a mixture of flour and fat (usually butter or pan drippings) cooked together. The cooking process serves two purposes: it toasts the flour, enhancing its flavor and reducing its raw taste, and it coats the starch granules in fat, preventing them from clumping together when added to the hot liquid.
The Roux Method:
To make a roux, melt the fat in a saucepan over medium heat. Whisk in the flour and cook, stirring constantly, until the mixture reaches the desired color. The color of the roux will influence the flavor of the gravy. A white roux, cooked for only a few minutes, has a mild, nutty flavor and is used for white sauces and cream-based gravies. A blond roux, cooked for a few minutes longer, has a slightly richer flavor and is used for classic brown gravies. A brown roux, cooked until it turns a deep brown color, has a pronounced nutty, almost burnt flavor and is often used in Cajun and Creole cooking.
Once the roux has reached the desired color, slowly whisk in the hot liquid, such as broth or stock, a little at a time, until the gravy is smooth and thickened. Simmer for several minutes to cook out the flour taste and allow the gravy to reach its desired consistency.
Advantages of Using Flour:
- Readily available in most kitchens.
- Adds flavor to the gravy.
- Relatively inexpensive.
Disadvantages of Using Flour:
- Can be prone to lumps if not properly incorporated.
- Contains gluten, making it unsuitable for those with gluten sensitivities.
- Requires cooking to eliminate raw flour taste.
Cornstarch: A Gluten-Free Alternative
Cornstarch is a pure starch derived from corn. It’s a popular gluten-free thickener that produces a clear, glossy gravy. Unlike flour, cornstarch has no flavor of its own, so it won’t affect the taste of your gravy.
The Cornstarch Slurry Method:
To use cornstarch, create a slurry by mixing it with cold water until it forms a smooth paste. Then, slowly whisk the slurry into the simmering gravy. Be sure to whisk constantly to prevent lumps from forming. The gravy will thicken quickly, so remove it from the heat as soon as it reaches the desired consistency.
Advantages of Using Cornstarch:
- Gluten-free.
- Produces a clear, glossy gravy.
- Thickens quickly.
Disadvantages of Using Cornstarch:
- Can become thin if overcooked.
- Doesn’t add any flavor to the gravy.
- Can create a slightly slimy texture if used in excess.
Arrowroot Powder: A Delicate Touch
Arrowroot powder is another gluten-free starch derived from the arrowroot plant. It’s known for producing a clear, glossy gravy with a smooth texture. It is similar to cornstarch in its application, but it doesn’t become as slimy as cornstarch if overused.
The Arrowroot Slurry Method:
Similar to cornstarch, arrowroot is used by first creating a slurry with cold water. Whisk the slurry into the simmering gravy and cook until thickened. It’s important to note that arrowroot thickens at a lower temperature than cornstarch, so be careful not to overcook it.
Advantages of Using Arrowroot Powder:
- Gluten-free.
- Produces a clear, glossy gravy with a smooth texture.
- Thickens at a lower temperature than cornstarch.
- Less likely to become slimy than cornstarch if overused.
Disadvantages of Using Arrowroot Powder:
- Can become thin if overcooked.
- Doesn’t add any flavor to the gravy.
- Can be more expensive than cornstarch or flour.
Tapioca Starch: A Versatile Option
Tapioca starch, also known as tapioca flour, is derived from the cassava root. It’s a versatile gluten-free thickener that produces a slightly chewy texture.
The Tapioca Starch Slurry Method:
Like cornstarch and arrowroot, tapioca starch is best used in a slurry. Mix it with cold water and whisk it into the simmering gravy. It’s important to note that tapioca starch can be slightly gummy if used in excessive amounts.
Advantages of Using Tapioca Starch:
- Gluten-free.
- Versatile thickener.
- Adds a slightly chewy texture to the gravy.
Disadvantages of Using Tapioca Starch:
- Can become gummy if overused.
- Doesn’t add any flavor to the gravy.
Potato Starch: A Less Common Choice
Potato starch is another gluten-free starch derived from potatoes. It has a neutral flavor and produces a clear, glossy gravy. However, it can be prone to breaking down if overcooked, so it’s best used in gravies that don’t require long simmering times.
The Potato Starch Slurry Method:
Again, a slurry is the way to go with potato starch. Mix it with cold water and whisk it into the simmering gravy.
Advantages of Using Potato Starch:
- Gluten-free.
- Neutral flavor.
- Produces a clear, glossy gravy.
Disadvantages of Using Potato Starch:
- Can break down if overcooked.
- Doesn’t add any flavor to the gravy.
The Unconventional Thickeners
Beyond the starches and flour, some less common but effective thickeners can add unique textures and flavors to your gravy.
Reducing the Liquid: A Natural Approach
One of the simplest ways to thicken gravy is to reduce the liquid by simmering it over low heat. This allows the water to evaporate, concentrating the flavors and thickening the sauce naturally. This method works best with gravies that already have a good body and just need a little extra thickening.
Advantages of Reducing the Liquid:
- Enhances flavor.
- No additional ingredients required.
Disadvantages of Reducing the Liquid:
- Time-consuming.
- Can lead to a salty gravy if not monitored carefully.
Pureed Vegetables: A Healthy and Flavorful Option
Pureed vegetables, such as butternut squash, sweet potatoes, or carrots, can add both thickness and flavor to gravy. Simply cook the vegetables until tender, puree them until smooth, and whisk them into the gravy. This method works well with gravies that complement the flavor of the vegetables.
Advantages of Using Pureed Vegetables:
- Adds nutrients and fiber.
- Enhances flavor.
- Adds natural sweetness.
Disadvantages of Using Pureed Vegetables:
- Can alter the color of the gravy.
- May not be suitable for all types of gravy.
Cream or Dairy: For Richness and Body
Adding cream, half-and-half, or even whole milk can thicken gravy and add richness and body. Heat the dairy product gently and whisk it into the gravy at the end of cooking. Be careful not to boil the gravy after adding dairy, as it can curdle.
Advantages of Using Cream or Dairy:
- Adds richness and flavor.
- Creates a smooth, velvety texture.
Disadvantages of Using Cream or Dairy:
- Increases the fat content of the gravy.
- Not suitable for all types of gravy.
- Can curdle if overheated.
Choosing the Right Thickener: Key Considerations
The best gravy thickener for you will depend on several factors, including your dietary needs, desired flavor, and the type of gravy you’re making.
Gluten Sensitivity: If you’re gluten-free, avoid flour and opt for cornstarch, arrowroot powder, tapioca starch, or potato starch.
Flavor Profile: If you want a gravy with a pronounced flavor, use flour and create a roux with a deep brown color. If you prefer a neutral flavor, use cornstarch, arrowroot powder, tapioca starch, or potato starch.
Desired Texture: For a clear, glossy gravy, use cornstarch, arrowroot powder, or potato starch. For a slightly chewy texture, use tapioca starch. For a rich, creamy texture, add cream or dairy.
Type of Gravy: White gravies often benefit from a flour-based roux or the addition of cream. Brown gravies can be thickened with flour, cornstarch, or arrowroot powder. Vegetable gravies can be thickened with pureed vegetables.
Tips for Gravy Success
No matter which thickener you choose, keep these tips in mind for gravy perfection:
- Whisk constantly when adding the thickener to prevent lumps from forming.
- Add the thickener slowly, a little at a time, until the gravy reaches the desired consistency.
- Simmer the gravy for several minutes to cook out any raw starch flavor.
- Season the gravy to taste with salt, pepper, and other seasonings as desired.
- Strain the gravy through a fine-mesh sieve for an ultra-smooth texture.
- Don’t overcook gravies thickened with cornstarch, arrowroot powder, or potato starch, as they can become thin.
Troubleshooting Common Gravy Problems
Even with the best intentions, gravy can sometimes go wrong. Here are some common problems and how to fix them:
- Lumpy Gravy: Whisk vigorously or strain the gravy through a fine-mesh sieve.
- Thin Gravy: Add more thickener, a little at a time, until the gravy reaches the desired consistency.
- Thick Gravy: Add more liquid, such as broth or water, until the gravy reaches the desired consistency.
- Salty Gravy: Add a pinch of sugar or a splash of vinegar to balance the flavors. Alternatively, add a peeled potato to the gravy while it simmers. The potato will absorb some of the salt. Remove the potato before serving.
- Bland Gravy: Add more seasonings, such as salt, pepper, garlic powder, onion powder, or herbs.

So, experiment, have fun, and enjoy the delicious results! With a little practice, you’ll become a gravy-making maestro in no time.
What are the most common gravy thickeners and what are their pros and cons?
The most common gravy thickeners include flour, cornstarch, arrowroot, tapioca starch, and even potato starch. Flour is a classic choice, readily available, and imparts a slightly nutty flavor. However, it requires cooking for several minutes to eliminate the raw flour taste and can sometimes result in a slightly opaque gravy if not properly incorporated.
Cornstarch offers a glossy, clear gravy and thickens quickly, making it a good option for last-minute adjustments. Arrowroot and tapioca starch also create clear gravies and are gluten-free alternatives, though they can become slimy if overcooked or reheated. Potato starch is another gluten-free option providing a smooth, slightly matte finish, but also susceptible to sliminess if not handled carefully.
How does the type of fat used in gravy affect the choice of thickener?
The type of fat significantly impacts the choice of thickener, particularly when using a roux, which is a mixture of fat and flour. Butter adds richness and flavor, but can brown quickly at higher temperatures, potentially affecting the color of the gravy. Animal fats, like drippings from roasted meats, contribute deeper, savory flavors and often require less flour to achieve the desired consistency.
For vegetarian gravies, olive oil or vegetable oil can be used, but may impart a different flavor profile than butter or animal fats. When using oils, it’s crucial to monitor the temperature closely to prevent burning and ensure the flour is fully cooked. The choice of fat also impacts the final texture and mouthfeel of the gravy, influencing the overall dining experience.
What is a roux, and how do you make one properly for gravy?
A roux is a foundational element in gravy making, consisting of equal parts fat and flour, cooked together until the flour is no longer raw. The cooking time of the roux influences the final flavor and color of the gravy. A white roux, cooked for just a few minutes, adds thickening power without much color. A blonde roux, cooked slightly longer, contributes a subtle nutty flavor.
To make a roux properly, melt the fat over medium heat, then whisk in the flour until smooth. Continuously stir the mixture to prevent burning and ensure even cooking. The cooking time depends on the desired flavor and color, ranging from a few minutes for a white roux to much longer for a brown or dark brown roux, which are used in sauces other than gravy.
What are the best techniques for preventing lumps when thickening gravy?
Preventing lumps is crucial for smooth gravy. One technique is to whisk the thickener into a small amount of cold liquid (water, broth, or milk) before adding it to the hot gravy. This creates a slurry that disperses more evenly and prevents the thickener from clumping when it hits the heat. Another method involves gradually whisking the dry thickener directly into the hot liquid, ensuring constant agitation.
Using a fine-mesh sieve to sprinkle the thickener into the gravy can also help prevent lumps. If lumps do form, immediately remove the gravy from the heat and whisk vigorously until smooth, or use an immersion blender to break down any remaining clumps. Straining the gravy through a fine-mesh sieve is another effective way to remove lumps and create a perfectly smooth sauce.
How do gluten-free thickeners compare to flour in terms of taste, texture, and application?
Gluten-free thickeners like cornstarch, arrowroot, and tapioca starch offer excellent alternatives to flour, providing comparable thickening power without gluten. They generally create a clearer, glossier gravy compared to flour, which can result in a slightly opaque sauce. However, some gluten-free thickeners, particularly arrowroot and tapioca starch, can become slimy if overcooked or reheated.
In terms of application, gluten-free starches often require a smaller amount than flour to achieve the same level of thickness. They are best incorporated into a cold slurry before being added to the hot liquid. While flour imparts a subtle nutty flavor, gluten-free starches are typically flavorless, allowing the other ingredients in the gravy to shine. Experimentation is key to finding the best gluten-free thickener based on desired texture and flavor.
Can I use more than one type of thickener in my gravy? What are the benefits and risks?
Yes, combining different thickeners can create a more complex and desirable gravy texture. For example, using a combination of flour and cornstarch can provide both the body of a flour-based gravy and the glossy finish of cornstarch. Blending different thickeners can also compensate for the weaknesses of a single thickener, such as the sliminess of some gluten-free starches.
However, there are risks involved. It’s crucial to understand how each thickener behaves individually before combining them. Over-thickening is a potential issue, so it’s best to start with smaller amounts of each thickener and gradually add more as needed. Improper ratios can also lead to undesirable textures, so careful experimentation and precise measurements are essential for success.
How do I adjust the thickness of my gravy after it’s already made?
If your gravy is too thin after cooking, you can thicken it by adding a small amount of slurry made from cornstarch or arrowroot mixed with cold water. Gradually whisk the slurry into the simmering gravy until it reaches the desired consistency. Alternatively, you can simmer the gravy uncovered for a few minutes, allowing some of the liquid to evaporate and thicken the sauce naturally. Be careful not to over-reduce the gravy, as it can become too salty or concentrated in flavor.
If your gravy is too thick, gradually add warm broth or stock, whisking constantly until it thins to the desired consistency. Adding liquid little by little prevents the gravy from becoming too thin. You can also pass the gravy through a fine-mesh sieve to remove any excess lumps that may be contributing to the thickness. Taste and adjust seasonings as needed after adjusting the thickness.
