How to thicken beef stroganoff without flour or cornstarch?

Beef stroganoff is a delicious and hearty meal that is loved by many people all over the world. It is usually made with beef, sour cream, onions, and mushrooms, and is served over noodles or rice. One of the challenges of making beef stroganoff is to make the sauce thick enough to coat the beef and vegetables, but not too thick that it becomes pasty. Most recipes use flour or cornstarch as a thickener, but what if you are unable to use those ingredients? In this blog post, we will take a look at some alternative ways to thicken beef stroganoff without using flour or cornstarch.

Using Sour Cream

Sour cream is a great ingredient to use as a thickener in beef stroganoff. It is also a key ingredient in the dish itself, so it will not interfere with the flavor. To use sour cream as a thickener, you will need to add it to the dish at the end of cooking. To do this, remove the beef and mushrooms from the pan and set them aside. Turn the heat down to low and stir in the sour cream until it is fully incorporated. Be sure not to let the sauce boil, as this could cause the sour cream to curdle. Once the sour cream is mixed in, return the beef and mushrooms to the pan and heat through.

Using Yogurt

Yogurt is another dairy product that can be used to thicken beef stroganoff. It has a similar tangy flavor to sour cream, but is slightly less thick. To use yogurt as a thickener, you will need to strain any excess liquid from it first. To do this, line a fine mesh strainer with cheesecloth and place it over a bowl. Add the yogurt to the cheesecloth and let it strain for 1-2 hours in the fridge. After straining, add the thickened yogurt to the beef stroganoff at the end of cooking and stir until fully incorporated.

Using Mashed Potatoes

Mashed potatoes are a surprising but effective way to thicken beef stroganoff. They are starchy and creamy, making them a perfect addition to the dish. To use mashed potatoes as a thickener, simply add a scoop of freshly made mashed potatoes to the sauce and stir until fully mixed in. The potatoes will add a creaminess to the sauce and will help to thicken it as well.

Using Vegetables

Vegetables such as carrots, celery, and onions can also be used to thicken beef stroganoff. This method is beneficial as it adds flavor and nutrition to the dish. To use vegetables as a thickener, chop them finely and cook them with the beef and mushrooms. Once they are softened, use an immersion blender to puree them until they are smooth. This will add a natural thickness to the sauce without the need for flour or cornstarch.


Thickening beef stroganoff without flour or cornstarch may seem like a daunting task, but with the methods above, it can be done easily and deliciously. Whether you choose to use sour cream, yogurt, mashed potatoes, or vegetables, you can add thickness to your dish without sacrificing flavor. Experiment and find the method that works best for you and enjoy your comforting bowl of beef stroganoff without any worries.


What can I use as a thickener instead of flour?

When it comes to cooking and baking, flour is often used as a thickener to give sauces, soups, and other dishes a thicker and creamier consistency. However, if you’re looking for an alternative to flour, whether because of dietary restrictions or to mix up your cooking routine, there are plenty of other thickening agents you can use.

One such alternative is cornstarch. Cornstarch can be subbed in for wheat flour at a 1:2 ratio. Because it’s a durable thickener, you only need half the amount of cornstarch to create the same effect. Not only is it a great thickener, but it’s also a great option for those who are gluten-free. Adding cornstarch to a gluten-free recipe is a great way to add softness and texture to baked goods while keeping them grain-free.

Another great option is arrowroot powder. It’s similar to cornstarch in that it’s gluten-free and easy to work with. It’s often used as a thickening agent in gravies, sauces, and baked goods. Like cornstarch, you’ll need to dissolve arrowroot powder in liquid before adding it to your dish. You can substitute arrowroot powder for flour in a 1:1 ratio, though be sure not to heat it up too much, as it can turn your dish slimy.

If you’re looking for a healthier option, you could try using ground chia seeds as a thickening agent. Chia seeds are high in fiber and omega-3s and have a subtle nutty flavor. To use chia seeds as a thickener, simply grind them up in a food processor or with a mortar and pestle and then whisk them into your liquid. Chia seeds can be used in a 1:1 ratio, but be aware it can add texture to your food, which may be desirable in some dishes but not others.

Lastly, you can also use tapioca starch as a substitute for flour. It’s often used in pie fillings and fruit sauces. To use tapioca starch, mix it with cold water and then add the mixture to your dish. It works especially well in acidic dishes, as it doesn’t break down as easily as other thickeners. You can substitute tapioca starch for flour in a 1:1 ratio.

There are many alternatives to flour when it comes to thickening your dishes. Whether you’re looking for a gluten-free option, a healthier option, or just a way to mix up your cooking routine, cornstarch, arrowroot powder, ground chia seeds, and tapioca starch are all great options to experiment with.

What can I add to stroganoff to thicken it?

If you are looking to thicken up your beef stroganoff, there are several options available to you. One of the simplest and most effective methods is to add a flour mixture or roux to the sauce. This approach works particularly well when making the sauce from scratch, but it can also be used to thicken pre-made or packaged stroganoff.

To make a roux, you will need to combine equal parts of flour and fat (such as butter or oil) over medium heat. Once the mixture is smooth and bubbly, you can gradually add it to your stroganoff sauce, whisking constantly to prevent lumps from forming.

If you prefer a simpler approach, you can add a mixture of flour and water directly to your stroganoff. Stir together one tablespoon of flour and two tablespoons of cold water in a small bowl, then add the mixture to your sauce. Be sure to whisk the sauce thoroughly as you add the flour mixture, as this will help prevent clumps from forming.

Another option for thickening beef stroganoff is to use cornstarch. Simply mix one tablespoon of cornstarch with one tablespoon of cold water until it forms a smooth paste. Then, add the mixture to your stroganoff sauce and simmer until the sauce thickens to your desired consistency.

Finally, you can use sour cream to thicken your beef stroganoff. Simply add a dollop of sour cream to your sauce and whisk it in until it is fully incorporated. However, be careful not to overheat the sauce once the sour cream has been added, as this can cause it to curdle.

There are several easy and effective methods for thickening beef stroganoff, depending on your preferences and the ingredients you have on hand. By experimenting with different techniques, you can achieve the perfect balance of flavor and texture in your stroganoff dish.

What can I use instead of cornstarch in beef?

If you are planning on using cornstarch as a thickener for beef and don’t have it on hand or can’t use it due to dietary restrictions, there are a few alternative options you can consider.

One possible option is arrowroot powder. This is a starchy flour that is extracted from the root of the arrowroot plant and has been used in traditional cooking for hundreds of years. Arrowroot powder acts as a great substitute for cornstarch and can be used in equal amounts. Like cornstarch, it is also gluten-free, making it a great choice for those with celiac disease or gluten sensitivities.

Another option is tapioca starch, which is derived from the cassava root and also works well as a thickener. Tapioca starch is often used in baking and cooking as a substitute for cornstarch and can be used in similar ratios. It has a neutral taste and is also gluten-free.

You could also consider using potato starch, which is made from the starch of potatoes. Like arrowroot and tapioca starch, it is gluten-free and can be used in equal amounts as cornstarch. Potato starch works particularly well when used in soups, stews, and sauces as it can add a nice thickness and texture.

There are several alternatives to cornstarch that you can use as a thickener for beef. Whether you choose arrowroot, tapioca starch or potato starch, all options are gluten-free, easily available, and can be used in equal amounts as cornstarch. Remember to adjust to taste and consistency and to cook the mixture long enough to allow the flour to thicken.

Does sour cream help thicken sauce?

Sour cream is a versatile ingredient that can be used in a variety of dishes. When it comes to thickening sauces, sour cream can be a useful addition to achieve a thicker and creamier consistency. Sour cream contains lactic acid, which can help to break down proteins in your sauce, causing it to thicken and become more rich. In addition, sour cream is naturally high in fat, which also contributes to thickening any sauce or soup.

It’s important to note that the amount of sour cream you add to your sauce will greatly impact the final texture. Adding too much sour cream can lead to a sauce that’s too thick and unpleasantly tangy. On the other hand, adding too little sour cream may not achieve the desired thickening effect that you’re after. It’s best to start by adding a small amount of sour cream and gradually increasing until you achieve the desired consistency.

When using sour cream to thicken your sauce, it’s important to be cautious when heating it. Sour cream can break and curdle at high temperatures, which can ruin your sauce and make it appear unappetizing. To avoid this, make sure to remove the sauce from the heat before adding the sour cream. It’s also helpful to stir the sour cream thoroughly into the sauce to prevent clumping and ensure an even texture.

Sour cream can be a useful ingredient to help thicken sauce. However, it’s important to use it cautiously and be mindful of the amount you add to achieve the desired texture. Remember to remove the sauce from the heat before adding sour cream and stir it thoroughly to prevent curdling. With these tips in mind, you can easily enhance the texture and flavor of your favorite sauces with sour cream.
