7 easy ways to create a homemade potato starch substitute - quickly and with minimal effort!

Table of Contents

Potato starch is a versatile thickener and stabilizer used in many cooking applications. It can be used to thicken sauces, make gravies, add moisture to baked goods, and more. Unfortunately, potato starch isn’t always easy to find at the grocery store. If you’re looking for an alternative, you can easily make your own potato starch substitute at home with a few simple steps. In this article, we’ll show you how to do it using seven different methods so you can pick the one that works best for you. So let’s get started!

Boil and Strain Method

Boiling and straining potatoes is an easy way to make your own potato starch substitute at home! All you need to do is get the right type of potato, simmer it in water for the appropriate amount of time, and then strain out the liquid. Remember that different types of potatoes require different simmering times – some may only need 10 minutes while others could take up to 30 minutes. Be sure to choose one that works with the amount of time you have available. Once it’s done cooking, simply strain out the liquid and discard any solids left behind. This will give you a starch substitute that can be used in various recipes. Now let’s look at another method for making a potato starch substitute: grating and straining.

Grate and Strain Method

Grate a potato and strain the liquid through cheesecloth for an easy grated-and-strained potato starch substitute. The process is relatively simple, but requires some sifting technique to ensure that all of the starch is removed from the potatoes. Start by soaking potatoes in water for at least 10 minutes before grating them. This will help release more of their natural starches into the water. Once they are done soaking, use a fine mesh strainer or cheesecloth to extract as much of the liquid from the potatoes as possible. Be sure to squeeze out any excess liquid so that only pure potato starch remains in your mixture. Finally, allow it to sit overnight before using it as a replacement for store-bought potato starch. With this method you can create your own homemade potato starch substitute with ease and convenience – no need to worry about running out! Transitioning now into talking about ‘freeze and strain method’, this next method involves freezing grated potatoes and then thawing them slightly before straining them through cheesecloth or a fine mesh strainer again.

Freeze and Strain Method

If you’re looking for an alternative to making your own potato starch substitute, why not try the ‘freeze and strain’ method? This process involves freezing a piece of raw potato, then grinding it with a grinder or food processor until it is broken down into small, grainy pieces. The next step is to sieve the resulting mash through a fine-mesh strainer to separate out the starch from the solids. The end result should be a powdery flour-like product that can be used as a potato starch substitute. It’s important to note that this technique will yield less starch than other methods, such as boiling and mashing potatoes, but it does offer an easy way to make your own potato starch substitute at home with minimal effort. With this method, you don’t need any special equipment or ingredients; just some frozen potatoes and something to grind them up with. Plus, once you have strained out all of the liquid from the mash, you are left with a dry powder that can easily be stored in an airtight container for future use. Transitioning now into using a food processor as another way to make your own potato starch substitute at home…

Use a Food Processor

Making your own potato starch substitute doesn’t have to be a hassle – try using a food processor for quick and easy results! This cooking technique is simple, safe, and efficient. Start by washing the potatoes thoroughly with cold water to remove any dirt. Then, peel the potatoes and cut them into small cubes before placing them in a food processor. Pulse the potatoes on high speed until they become a fine paste-like consistency. Scrape down the sides of the mixing bowl occasionally to ensure all the pieces are adequately blended together. Once finished, transfer this mixture onto cheesecloth or muslin cloth for straining away any excess liquid. After allowing it to sit for several hours, you can start collecting the starch that settles at the bottom of your container; this is now ready to use as an alternative potato starch substitute! Food safety should always be taken into account when dealing with raw ingredients such as potatoes; make sure you take all necessary precautions when handling this product. With that said, this method offers an effective way of creating your own potato starch substitute without too much effort involved – perfect for busy cooks! Transitioning seamlessly into our next section we will discuss how microwaving can be used as another approach.

Microwave Method

For an even simpler solution, try using your microwave to whip up a potato starch substitute in no time! To get started, select the potatoes you want to use and wash them thoroughly. Cut the potatoes into small cubes as this will help reduce cooking time. Place the cubes into a bowl and fill with just enough water to cover them. Microwave for 3-4 minutes or until they are fork tender. Once done, drain off any excess liquid and mash the potatoes until smooth. Allow to cool before transferring to an airtight container for storage. The resulting puree can be used as a potato starch substitute in your recipes. Plus, it’s super quick and easy – perfect for when you need a last minute substitution! Moving on, another option is to dehydrate your potatoes…

Dehydrate Method

Don’t want to wait? Try dehydrating potatoes for a faster potato starch substitute right at home! Dehydrating potatoes is a quick and easy method of extracting potato starch. To do this, first start by peeling and grating the potatoes. Then, soak the grated potatoes in cold water for 10-15 minutes; this will reduce the amount of time needed for cooking later on and also helps with starch extraction. After soaking, pour off the excess water and spread the grated potato pieces on a tray or baking sheet lined with parchment paper. Bake them for 45 minutes at 250°F to evaporate all moisture from the potatoes; remove any pieces that have already become crispy before they burn. Once all moisture has been removed, grind up the dried potato pieces into a fine powder using either a food processor or blender. The result should be your own homemade potato starch substitute!


Making your own potato starch substitute at home is a great way to save money and have control over the ingredients you use. You can easily make a substitute with methods like boiling and straining, grating and straining, freezing and straining, using a food processor, microwaving or dehydrating potatoes. Whichever method you choose, it’s sure to be cheaper than buying store-bought substitutes. With these simple steps you’ll be able to create a healthier, more affordable version of your favorite recipes in no time! So why not give it a go? It may take some practice to perfect the process but the results are worth it!
