How Long Does Tofu Last?

If you’re a fan of tofu or have recently discovered its versatility and health benefits, you may find yourself wondering, “How long does tofu last?”

Whether you’ve bought a pack of tofu and need to plan your meals accordingly or you’ve prepared a tofu-based dish and are uncertain about its storage duration, understanding the shelf life of tofu is essential for maintaining its quality and ensuring food safety.

What is tofu?

Tofu, also referred to as bean curd, is a versatile and mild-tasting food derived from soybeans. It holds significant dietary importance in the culinary traditions of China, Japan, Korea, and Southeast Asia.

The production process involves soaking dried soybeans, crushing them, and boiling the mixture. Through this process, the mixture is divided into two components: solid pulp known as okara and soy milk. To separate the curds from the whey, soy milk is combined with salt coagulants like calcium and magnesium chlorides and sulfates.

Depending on the production method, tofu can be categorized into extra soft, soft (silken), firm, or extra firm varieties. It is inherently gluten-free and low in calories. Moreover, it does not contain cholesterol and serves as an excellent source of iron and calcium.

Tofu can be enhanced with flavors like ginger or onion, as well as seasoned with various spices. It lends itself well to a range of cooking techniques, including grilling, deep-frying, simmering, stir-frying, steaming, or enjoying it fresh. Toppings such as tapioca or sweet syrups can be added to enhance its taste and presentation.

How long does tofu last in the fridge?

Tofu, a versatile and nutritious food, has gained popularity due to the increasing adoption of vegan diets. However, it’s important to recognize that tofu, like any other food, has a limited shelf life and can eventually spoil. The duration for which tofu remains fresh depends on various factors, including storage methods, duration of storage, and whether it is unopened or opened.

When unopened and refrigerated, the use-by date indicated on the package should be followed to determine the shelf life of tofu. Once opened, refrigerated tofu typically remains good for approximately 3 to 5 days, provided it has been stored correctly. Cooked tofu generally has a slightly longer shelf life compared to raw tofu, usually extending by an additional 2 or 3 days.

It is crucial to be aware that if you are uncertain whether your tofu has gone bad, you can rely on your senses to assess its freshness. Spoiled tofu often darkens in color and may emit a sour or rotten smell. Trust your senses in such cases and refrain from consuming tofu exhibiting any of these signs.

How long does tofu last in the freezer?

When stored correctly, tofu can remain fresh in the freezer for a period of 4 to 6 months. Freezing tofu not only extends its shelf life but also transforms its texture, resulting in a denser and spongier consistency with numerous small pores that are ideal for absorbing and retaining flavors.

To freeze tofu at home, start by cutting whole blocks of tofu into your desired size and then carefully arrange them on a sheet tray, or place them in a freezer-safe container or bag. Once the tofu pieces have frozen completely, which typically takes around 4 to 6 hours, the process is complete!

If you initially froze the tofu on a baking sheet, it is advisable to transfer it to a sealed container for storage. By following these steps, frozen tofu can be preserved for up to one year in the freezer.

How long does tofu last on the shelf?

Most stores offer two primary types of tofu: shelf-stable and refrigerated. The shelf-stable variety has a longer shelf life, typically lasting around 2-3 months before it spoils. If you purchase tofu from the refrigerated section, it’s advisable to store it in the refrigerator.

Consuming expired tofu is not recommended. To determine if your tofu is still suitable for consumption, rely on your senses. Spoiled tofu often undergoes color darkening and may emit a sour or rotten odor. If you notice any of these signs, it’s best to refrain from eating it.

After opening, refrigerated tofu generally remains fresh for 3 to 5 days when stored appropriately. Cooked tofu has a slightly extended shelf life compared to raw tofu and can last an additional 2 or 3 days in the refrigerator.

How to store tofu properly

Storing tofu can be a bit challenging since it has a tendency to dry out quickly. However, with proper storage techniques, you can safely keep tofu in the refrigerator or freezer for future use.

When storing tofu in the fridge, it’s recommended to leave it in its original packaging until you’re ready to use it. As soon as you bring the tofu home from the store, promptly place it in the refrigerator while still in its original package.

To ensure optimal freshness, transfer the tofu to an airtight container and cover it with water, making sure the water level is just above the tofu. It is preferable to use filtered water to avoid any potential contaminants that could harm the tofu. Remember to change the water daily to maintain its quality.

In case you’ve already prepared the tofu for a dish, there is no need to add water. Flavored and cooked tofu can be stored in an airtight container in the fridge.

If you find yourself with excess unopened packages of tofu, you can store them in the freezer. Simply place the unopened package directly in the freezer. When you’re ready to use the tofu, defrost it before cooking, following your usual method. Keep in mind that defrosted tofu may have a slightly different taste and texture. It tends to become chewier and spongier.

Even if you’ve already opened a package of tofu, you can still freeze it for later use. Drain any excess moisture from the tofu, and then transfer it to a freezer bag or plastic bag. Place the bag in the freezer and defrost the tofu when needed. It’s important to plan ahead, as tofu takes time to defrost. For recipes requiring tofu, allocate at least two days for proper thawing.

How to tell if tofu has gone bad

Determining if tofu has spoiled can be done through various indicators. An initial notable sign of spoiled tofu is its strong and unpleasant smell. If it emits a sour or disagreeable odor, it is likely to have gone bad.

Another aspect to consider is its texture. Spoiled tofu typically appears darker in color and has a slimy consistency. When uncertain about the freshness of tofu, it is advisable to discard it rather than risk consuming it.

Tofu is classified as a high-risk food due to its potential to facilitate the growth of harmful microorganisms, such as bacteria. Consumption of contaminated tofu can potentially lead to illness. It is recommended to employ all your senses to assess the freshness of tofu.

Observe its appearance, feel its texture, and evaluate its smell. Spoiled tofu tends to exhibit a tan or even brownish hue, accompanied by the presence of mold or discoloration.

Additionally, it often feels slimy and emits a sour or rotten odor, whereas fresh tofu should be odorless. Should any of these signs of spoilage be detected, it is advisable to dispose of the tofu promptly.

Can you eat expired tofu?

The expiration date printed on tofu packaging should not be mistaken for the sell-by or manufacturing date. If your tofu has passed its expiration date or shows common signs of spoilage, it is essential to avoid consuming it. Expired tofu is no longer safe to eat and should be discarded.

Spoiled tofu can be identified by its sour smell and slimy texture. Eating spoiled tofu is not safe and can lead to symptoms such as nausea and vomiting. If you still choose to consume spoiled tofu, it is crucial to take the necessary precautions to prevent food poisoning.

Proper handling and storage of tofu are important to maintain its quality and safety. Unopened tofu can generally be consumed safely for approximately 2-3 months after the production date indicated on the packaging. Placing unopened tofu in the refrigerator can extend its shelf life by up to a week.

However, if you do not plan to use the tofu in the near future, the most suitable storage method is freezing. Unopened frozen tofu can be preserved in the freezer for several months or even years.

Once you open a package of tofu, any remaining uncooked tofu should be stored in the refrigerator at or below 40 degrees Fahrenheit for a maximum of four days. It is crucial to handle tofu with the same care as other potentially hazardous foods like meat, chicken, or fish. This involves washing your hands before handling tofu and avoiding cross-contamination with other foods.

Leftover tofu is a versatile ingredient that can be used in a variety of dishes.

One of the simplest ways to repurpose it is by stir-frying it with vegetables, seasoning, and sauce to create a quick and healthy meal.

Additionally, tofu can also be incorporated into desserts like cheesecakes, chocolate mousse, pudding, and ice cream, adding a creamy texture and protein boost.

For a plant-based alternative to eggs, tofu can be used in scrambles, frittatas, and quiches.

Another option is to blend it into a smoothie to thicken and enhance its nutritional value.

For a heartier option, extra-firm tofu can be grilled or cut into cubes and cooked on skewers.

With so many possibilities, leftover tofu is an ingredient that should not go to waste.


In conclusion, the shelf life of tofu can vary depending on various factors, such as the type of tofu, how it is stored, and whether it is opened or unopened.

Generally, unopened tofu can last for up to two weeks in the refrigerator, while opened tofu should be consumed within 3 to 5 days.

However, it is important to always check for signs of spoilage, such as a sour smell, slimy texture, or mold growth, before consuming tofu, even if it is within its recommended shelf life.

To extend the shelf life of tofu, it can be frozen for up to 6 months, although this can affect its texture and taste. Overall, it is best to use fresh tofu whenever possible and to store it properly to ensure its quality and safety.
