Salt Water Soak for Frying Potatoes: Worth the Extra Step?



Should you soak potatoes in salt water before frying? This is a question that has been asked by many home cooks and professional chefs alike. Some argue that soaking the potatoes in salt water helps remove excess starch, resulting in crispier fries. Others believe it's unnecessary and can even make the fries too salty.

Potatoes are a staple food item in many households around the world, enjoyed for their versatility and delicious taste. From mashed potatoes to baked potatoes, there are countless ways to enjoy this humble vegetable. However, when it comes to making french fries or potato chips at home, opinions on whether or not to soak them before frying can be divisive.

So what's the answer? Keep reading to find out as we explore the science behind soaking potatoes in salt water before frying and weigh up both sides of this debate.

Should You Soak Potatoes in Salt Water Before Frying?

Potatoes are a staple food that can be cooked and enjoyed in countless ways. One popular method is frying them up to create crispy, golden brown potato chips or French fries. But before you get started, you may have heard that soaking the potatoes in salt water can make a difference in the end result. In this article, we'll explore whether or not you should soak your potatoes before frying and what benefits it may have.

What Happens When You Soak Potatoes Before Frying?

Soaking potatoes involves submerging them in salt water for a period of time before cooking. The idea behind this technique is to remove excess starch from the potato's surface, which can prevent them from sticking together while frying and result in crispier end products.

During soaking, water enters into the potato cells through osmosis and removes some of their internal starch content as well. This process also helps to remove dirt and debris on their skin.

Benefits of Soaking Potatoes

One benefit of soaking potatoes is that it results in even browning during frying due to reduced moisture levels on its surface. Additionally, it removes extra starches that may cause clumping when fried with other pieces.

Another advantage is health-related: removing excess starch reduces acrylamide formation when heated at high temperatures during cooking; thus reducing risks associated with acrylamide consumption such as increased cancer risk (1).

Finally, soaked fries will cook evenly because they all take up similar amounts of oil; if one isn't cooked thoroughly enough then others won't be either – so using less oil than usual would help achieve an evenly fried batch since they all cook simultaneously without needing frequent flipping.

How Long Should You Soak Your Potatoes?

The recommended duration for soaking your potatoes varies according to personal preference but between 30 minutes to two hours after slicing works well across most recipes.

However, soaking time will depend on many factors such as the thickness of your slices. A good rule of thumb is to soak potatoes for at least 30 minutes and up to two hours if you're doing it overnight.

What About Salt?

Adding salt enhances the flavor and crisping properties further but also aids in breaking down starches – a win-win situation. To prepare your salt solution, mix one tablespoon of salt with four cups of cold water until dissolved completely before adding sliced potatoes into it.

Tips for Soaking Potatoes

Here are some tips that may come in handy while soaking:

  • Ensure uniformity in slicing so that every piece gets soaked evenly without any chunky areas.
  • Use a large bowl or container so that all potato slices can be submerged properly.
  • Rinse off excess starch under running water after removing them from the solution
  • Dry out thoroughly using paper towels or a clean cloth before frying
  • Finally: keep an eye on your timing during frying itself since this step is crucial to ensure perfectly cooked fries.


So, should you soak potatoes in saltwater before frying? Based on our research and discussion above; we can conclude that yes – soaking potatoes does have its advantages when it comes down to making crispy golden fries or chips!

By removing excess surface moisture through osmosis while also reducing acrylamide formation risks due to removal of excess starches, using less oil than usual helps achieve an even fry throughout bags/batches leading towards more uniformly cooked products which everyone loves!


Why should you soak potatoes in salt water before frying?

It is a well-known fact that freshly sliced potatoes tend to turn brown and lose their flavor if not cooked immediately. To prevent this from happening, chefs often recommend soaking the potato slices in salt water before frying them. Soaking the potato slices helps remove excess starch, which can cause sogginess and burning during cooking. The saltwater also draws out some of the moisture from the potatoes, which helps create a crispy exterior when fried.

Additionally, soaking potatoes in salt water adds flavor to them as it allows for better seasoning absorption during cooking. This simple step may seem insignificant but can make a big difference when it comes to achieving perfectly crisp fries or chips that are golden on the outside and tender on the inside.

One important thing to note is that you should not leave your potato slices soaked for too long as they might start breaking down and lose their sturdiness while being fried.

What kind of salt should I use when soaking my potatoes?

The type of salt used for soaking your sliced potatoes matters as much as how long you leave them in there. Chefs recommend using regular table or kosher sea salts rather than iodized salts due to their larger flakes size; iodized salts tend to dissolve quickly than other types hence might make your solution even more salty than intended.

To prepare your soak solution mix one tablespoon of either table or sea-kosher with half cup warm (not hot) water until dissolved then add 3 cups cold tap-water into which you will immerse rinsed & drained potato-slices covering them completely up-to an inch over top surface layer – this ensure consistent salinity throughout all pieces resulting evenly flavored crisps/fries/chips once cooked!

How long should I soak my sliced potatos before frying?

You do not need more than 30 minutes unless working with very thick-cut fries/chips.In general,it's best practice after cutting your potatoes into desired shape to submerge them in salt water for 20-30 minutes,rinsing them and thoroughly drying before cooking.This will help remove excess starch, enhance their flavor and crispiness.

Remember that soaking sliced potatoes longer than recommended can cause the potato slices to start breaking down and losing their sturdiness while being fried. It's also important to note that you should rinse the potato slices after soaking them in saltwater or they may become too salty once cooked.

Can I still soak my potatoes if I am short on time?

Yes! You can achieve some of the benefits of soaking even when short on time. Instead of a 30-minute soak, try submerging your sliced potatoes in cold water for at least 10 -15 minutes before patting dry with paper towels. This quicker method helps remove some starch from the surface layer, resulting in slightly crisper fries/chips once cooked.

If you have more time, combine cold water with ice cubes which help intensify crisping effect by ensuring optimal frying temperature is maintained as soon as chips/fries are added to hot oil

What type of oil should I use when frying my soaked potatos?

The type of oil used during frying plays an important role not only because it affects flavor but also due its smoke point.You need a high smoke point oil such as vegetable/corn/peanut or sunflower which won't burn off quickly under high heat exposure while having neutral taste profile not interfering with natural flavors present within your perfectly prepared crispy fried/baked/sautéed dish!

It's recommended using neutral oils like corn or vegetable oils rather than olive oil since they have higher smoke points hence better suited for deep-frying methods.It’s crucially paramount maintain constant optimal temperature throughout cooking process so ensure using quality thermometer checking frequently whilst adjusting flames accordingly avoid burning overcooking!
