Potatoes are one of the most versatile vegetables, used in countless dishes worldwide. However, they contain a significant amount of starch, which can affect their texture and nutritional value. Excess starch in potatoes can make them sticky when cooking or frying and can lead to uneven cooking. For certain recipes, especially crispy fries or fluffy mashed potatoes, it’s essential to reduce the starch content to achieve the best results.

Removing starch from potatoes is also beneficial for those aiming to lower their carbohydrate intake, as starch is a primary source of carbs in potatoes. Fortunately, there are simple and effective methods to reduce starch content without compromising their taste or quality. This article explores six tried-and-tested tips to remove starch from potatoes to enhance their texture, flavour, and nutritional value.
Soaking
Soaking is one of the easiest and most effective ways to remove starch from potatoes. Once peeled and cut, place the potatoes in a large bowl of cold water and let them soak for at least 30 minutes. For better results, you can soak them for a few hours or even overnight in the refrigerator.
The water absorbs the surface starch, which is visible as a cloudy layer in the bowl. After soaking, discard the water and rinse the potatoes before using them. This method works well for dishes like French fries, where reducing starch is essential for achieving a crispy texture.

Blanching
Blanching is another effective technique for removing starch, especially if you’re preparing potatoes for dishes that require boiling or frying. Start by peeling and cutting the potatoes into your desired size. Bring a pot of water to a boil, then add the potatoes and let them cook for 2-3 minutes.
After blanching, remove the potatoes and immediately transfer them to a bowl of ice-cold water. This stops the cooking process and helps release excess starch. You’ll notice the water becoming cloudy as the starch is released. Drain the potatoes and pat them dry before proceeding with your recipe.
Rinsing Thoroughly
Rinsing is a straightforward method that involves washing the potatoes under running water. After peeling and cutting the potatoes, place them in a colander and rinse them thoroughly. Rub the pieces gently with your hands to ensure the surface starch is washed away.
You can also rinse the potatoes multiple times for better results. Each time you rinse, the water should become less cloudy, indicating that the starch is being removed. This method is quick and effective for everyday cooking and doesn’t require additional preparation time.

Cooking Techniques
Certain cooking techniques can also help reduce the starch content in potatoes. Boiling is a common method that not only cooks potatoes but also removes some starch. To maximise starch removal, use a large pot of water and avoid overcrowding the potatoes.
As the potatoes boil, the starch dissolves into the water, which can be drained after cooking. You can enhance the process by changing the water halfway through boiling. This method is ideal for mashed potatoes or potato salads, where a lower starch content results in a smoother texture.
Fermentation
Fermentation is a less common but highly effective method to reduce starch in potatoes. To ferment potatoes, place peeled and cut pieces in a bowl of water and leave them at room temperature for 24-48 hours. During this time, natural fermentation processes break down starches in the potatoes.
You’ll notice a slight sour smell as the fermentation progresses. After the process is complete, rinse the potatoes thoroughly under running water to remove any residual sourness. This technique not only reduces starch but also improves the digestibility of the potatoes, making them a healthier option for some individuals.

Add Acidic Ingredients
Adding acidic ingredients like vinegar or lemon juice to the water while soaking or cooking potatoes can help break down starches more effectively. The acid reacts with the starch, causing it to release more easily.
To use this method, add a tablespoon of vinegar or lemon juice to a bowl of water and soak the potatoes for 30 minutes to an hour. Alternatively, when cooking the potatoes, you can add the acidic ingredient to the boiling water. This technique is particularly useful for recipes that require firmer potato textures, such as potato salads or roasted potatoes.
