Gravy, the velvety sauce that elevates countless dishes, can be a culinary tightrope walk. Too thin, and it’s a watery disappointment; too thick, and it’s an unappetizing gloop. While flour, cornstarch, and roux are the traditional go-to thickeners, an unexpected hero might be lurking in your refrigerator: mashed potatoes. But can you really use mashed potatoes to thicken gravy, and more importantly, should you? Let’s delve into the possibilities, techniques, and potential pitfalls of this unconventional approach.
The Potato Potential: Why Mashed Potatoes Might Work
The secret lies in the starch. Potatoes, particularly starchy varieties like Russets, are packed with it. When cooked, this starch gelatinizes, absorbing water and swelling, which is the very principle behind the thickening action of many sauces and gravies. Mashed potatoes, being already cooked and mashed, offer a pre-gelatinized starch source, making them a potentially quick and convenient thickener.
Beyond the starch, mashed potatoes add a subtle creaminess and body to the gravy. They contribute a richness that can be particularly appealing, especially in savory gravies served with roasted meats or poultry.
Understanding Starch Gelatinization
The process of starch gelatinization is crucial. Raw starch granules are insoluble in cold water. However, when heated in the presence of water, they absorb the liquid, swell, and eventually burst, releasing amylose and amylopectin – the two main starch molecules. This process creates a viscous mixture, the basis of many thickened sauces. Mashed potatoes shortcut this process, offering readily available gelatinized starch.
Flavor Considerations
While starch is the primary contributor to thickening, the flavor of your mashed potatoes will inevitably influence the taste of your gravy. Plain, unseasoned mashed potatoes will offer the most neutral base. Heavily seasoned potatoes, especially those with garlic, herbs, or cheese, will impart their flavors to the gravy, potentially complementing or clashing with the existing flavors.
The Dos and Don’ts of Potato-Thickened Gravy
Using mashed potatoes to thicken gravy isn’t a foolproof method. Success hinges on understanding the nuances and adhering to certain best practices.
Choosing the Right Potatoes
The type of potato matters. Starchy potatoes like Russets and Idaho potatoes are ideal because they release more starch upon cooking and mashing. Waxy potatoes, such as red potatoes or Yukon Golds, contain less starch and more moisture, making them less effective as a thickener. They can still be used, but you might need a larger quantity.
Mashed Potato Preparation: Achieving the Right Consistency
The consistency of your mashed potatoes is crucial. They should be smooth and free of lumps. Lumpy mashed potatoes will translate to lumpy gravy, which is undesirable. Using a potato ricer or food mill can help ensure a smooth texture. Overmixing mashed potatoes can lead to a gluey texture, so avoid excessive stirring.
Incorporating Mashed Potatoes into Gravy: A Gradual Approach
Don’t dump a large amount of mashed potatoes into your gravy all at once. This can lead to clumping and uneven thickening. Start by adding a small amount of mashed potatoes (about a tablespoon or two) at a time, whisking continuously to incorporate it smoothly. Allow the gravy to simmer gently for a few minutes after each addition to assess the thickening effect.
Adjusting for Flavor and Seasoning
After thickening with mashed potatoes, taste your gravy and adjust the seasoning as needed. The potatoes may dilute the existing flavors, so you might need to add more salt, pepper, herbs, or other seasonings to achieve the desired taste.
Dealing with Lumps: Prevention and Solutions
Lumps are the enemy of smooth gravy. Preventing them is always easier than fixing them. Besides using smooth mashed potatoes and incorporating them gradually, consider straining the gravy through a fine-mesh sieve after thickening to remove any remaining lumps. If you still encounter lumps, an immersion blender can be used carefully to smooth out the gravy. However, be cautious not to over-blend, as this can make the gravy gummy.
Considering Other Ingredients
The other ingredients in your gravy will also influence the thickening process. Gravies made with rich stocks or pan drippings may require less mashed potatoes to achieve the desired consistency than those made with water or a weaker broth.
When Mashed Potatoes are the Perfect Gravy Thickeners
While mashed potatoes can be a convenient thickener, there are certain situations where they truly shine.
Rescue Mission: Fixing a Thin Gravy
If you’ve made a gravy that’s too thin and you’re short on time or other thickening agents, mashed potatoes can be a lifesaver. They offer a quick and easy solution for adding body and thickness to a lackluster gravy.
Boosting Creaminess and Flavor
For gravies where you want to add extra creaminess and a subtle potato flavor, mashed potatoes can be a welcome addition. This is particularly true for cream-based gravies or those served with dishes where the potato flavor complements the overall meal.
Using Leftover Mashed Potatoes
Rather than letting leftover mashed potatoes go to waste, use them to thicken your gravy. This is an excellent way to reduce food waste and create a delicious and resourceful meal.
Potential Downsides of Using Mashed Potatoes
Despite the potential benefits, there are some drawbacks to consider when using mashed potatoes as a gravy thickener.
Texture Alterations
While mashed potatoes can add creaminess, they can also alter the overall texture of the gravy. Depending on the amount used, the gravy might become slightly thicker or heavier than desired. This is less of an issue if the potatoes are perfectly smooth and incorporated gradually.
Flavor Changes
The flavor of the mashed potatoes can significantly impact the final taste of the gravy. If the potatoes are heavily seasoned or have strong flavors, they can overpower the other ingredients in the gravy. This is especially true if the gravy has delicate or subtle flavors.
Potential for Gummyness
Overmixing or overcooking mashed potatoes can result in a gluey or gummy texture. If you add too much of this type of mashed potatoes to the gravy, it can also become gummy. Avoiding overmixing and adding the potatoes gradually can help prevent this issue.
Color Changes
Adding mashed potatoes to gravy can slightly lighten the color. This might be a concern if you’re aiming for a rich, dark-colored gravy. You can compensate for this by adding a small amount of gravy browning or by using a darker stock.
Comparing Mashed Potatoes to Other Thickeners
Mashed potatoes are just one of many options for thickening gravy. Let’s compare them to some other common thickeners:
Flour
Flour is a classic gravy thickener. It can be used to create a roux (a mixture of flour and fat) or as a slurry (a mixture of flour and cold water). Flour adds a smooth texture but can sometimes leave a starchy taste if not cooked properly.
Cornstarch
Cornstarch is a pure starch that provides a glossy, translucent finish to gravy. It’s a potent thickener but can become thin again if overcooked. Cornstarch is best used as a slurry.
Arrowroot Powder
Arrowroot powder is another starch-based thickener that produces a clear, glossy sauce. It’s less likely to turn gummy than cornstarch and is a good option for those with corn allergies. Like cornstarch, it should be used as a slurry.
Roux
Roux, a cooked mixture of flour and fat (usually butter), is a fundamental element in many sauces and gravies. The cooking process mellows the flour’s starchy taste and adds richness. Roux can be white, blond, or brown, depending on the cooking time, with darker roux providing deeper flavors.
| Thickener | Pros | Cons |
|---|---|---|
| Mashed Potatoes | Convenient, adds creaminess, uses leftovers | Can alter flavor, potential for gummyness, may lighten color |
| Flour | Readily available, versatile, creates a smooth texture | Can have a starchy taste if not cooked properly |
| Cornstarch | Potent thickener, produces a glossy finish | Can become thin if overcooked |
| Arrowroot Powder | Clear, glossy sauce, less likely to turn gummy | Can be more expensive than other options |
| Roux | Adds depth of flavor, versatile | Requires more preparation time, can be tricky to get the consistency right |

FAQ: What kind of mashed potatoes works best for thickening gravy?
The best mashed potatoes for thickening gravy are those that are relatively plain and made with starchy potatoes like Russets or Yukon Golds. These varieties release a significant amount of starch when cooked and mashed, providing superior thickening power compared to waxy potatoes like red potatoes. Avoid overly seasoned or flavored mashed potatoes, as their additional ingredients might clash with the flavor profile of your gravy.
Also, ensure the mashed potatoes are smooth and free of lumps for best results. Lumps in the mashed potatoes could create a grainy texture in your gravy, which is undesirable. If your mashed potatoes are a bit lumpy, consider using an immersion blender or passing them through a fine-mesh sieve before adding them to the gravy.
FAQ: How much mashed potato should I add to my gravy?
The amount of mashed potatoes needed to thicken your gravy depends on how thin the gravy is and how thick you want it to be. It’s always best to start with a small amount and gradually increase it until you achieve the desired consistency. A good starting point is about one tablespoon of mashed potatoes per cup of gravy.
Stir the mashed potatoes in thoroughly and allow the gravy to simmer for a few minutes. This will give the starch in the potatoes time to activate and thicken the gravy. If it’s still too thin, add another tablespoon of mashed potatoes, stir, and simmer again. Repeat this process until the gravy reaches your preferred thickness.
FAQ: Will adding mashed potatoes change the flavor of my gravy?
While adding mashed potatoes will subtly alter the flavor of your gravy, the change is usually minimal and often enhances the overall taste, especially if the potatoes are well-seasoned. Plain mashed potatoes can add a slight earthy note and a creamy texture that complements many gravies.
However, if your mashed potatoes are heavily seasoned with garlic, cheese, or other strong flavors, they could significantly impact the gravy’s flavor profile. In such cases, it’s essential to taste the gravy frequently as you add the potatoes and adjust the seasoning as needed to maintain a balanced flavor.
FAQ: Can I use instant mashed potatoes to thicken gravy?
Yes, you can use instant mashed potatoes to thicken gravy, but the results might not be as smooth or flavorful as using homemade mashed potatoes. Instant potatoes are essentially dehydrated potato flakes, and they rehydrate and thicken liquids quickly. They are convenient but can sometimes impart a slightly artificial taste.
To use instant mashed potatoes, start with a very small amount, about half a teaspoon per cup of gravy. Sprinkle the flakes into the gravy while stirring constantly to prevent clumping. Allow the gravy to simmer for a minute or two for the flakes to fully hydrate. Taste and add more flakes if necessary, being careful not to over-thicken.
FAQ: What are the advantages of using mashed potatoes over flour or cornstarch?
Using mashed potatoes as a thickening agent offers several advantages. Firstly, it’s a natural and often readily available option, especially after a holiday meal. Secondly, it can add a subtle depth of flavor and creamy texture to your gravy that you might not achieve with other thickeners.
