How Long Can Tofu Sit Out At Room Temperature?

Whether you are vegan, vegetarian, or just looking to add more plant-based proteins to your diet, tofu is an undeniably popular food choice. Not only does it have tons of health benefits, but its mild flavor allows for endless culinary possibilities.

But as with regular proteins like chicken or beef, it’s important that the handling of tofu be done correctly and safely in order to prevent any illnesses.

In fact, one of the most important factors you need to think about when it comes to your tofu preparation is how long it can stay out at room temperature before it becomes unsafe to consume.

How Long Can Tofu Sit Out At Room Temperature?

Tofu should not be left out at room temperature for more than two hours, according to the USDA. If the room temperature is above 90°F (32°C), this time frame shortens to just one hour.

After this time, the risk of bacterial growth and the potential of food poisoning can significantly increases.

This is why it’s essential to keep track of the time your tofu spends outside of the refrigerator and ensure that it doesn’t exceed the recommended limit.

If you’re unsure whether your tofu has been sitting out for too long, it’s best to be on the side of caution and discard it to avoid any potential health risks.

How Long Can Cooked Tofu Sit Out At Room Temperature?

With many of us being busy these days, it’s not uncommon for people to accidentally leave cooked tofu sitting out on the counter or table. However, even for cooked tofu, similar principles apply, two hours no more!

If you do discover that your cooked tofu has been left out for more than the recommended time frame, it’s better to discard it rather than risking potential health issues.

To prevent such situations, you can set reminders or timers to help you remember to store your cooked tofu properly.

How Do You Keep Tofu Fresh Without A Refrigerator?

Keeping tofu fresh without a refrigerator can be challenging, but there are some methods you can try to prolong its shelf life and maintain its quality:

  • Cooler or icebox: If you don’t have access to a refrigerator, you can use a cooler or icebox with ice packs to keep the tofu cold. Place the tofu in an airtight container, submerged in water, and store it in the cooler.
  • Saltwater brine: Another method to preserve tofu is by using a saltwater brine solution, and place the tofu in an airtight container filled with the brine. The salt will help inhibit bacterial growth and extend the tofu’s shelf life.
  • Store away from sunlight: Storing unopened shelf-stable tofu in a cupboard away from direct sunlight can help it last longer, as long as it is packaged in aseptic containers. This type of packaging protects the tofu from contamination and allows it to be stored at room temperature until the expiration date mentioned on the package.

Can You Still Eat Tofu That’s Passed It’s Expiry Date?

So, what happens when you discover that the tofu has passed its expiry date? Is it still safe to eat, or should you discard it immediately? Well, first and foremost, it’s important to understand that expiry dates are not definitive indicators of food spoilage.

In many cases, they serve as guidelines to help you determine the product’s optimal freshness and quality. That being said, it’s crucial to rely on your senses and judgment when deciding whether or not to consume tofu past its expiry date.

Signs That Your Tofu Has Gone Bad

Before consuming tofu that has passed its expiry date, inspect it for any signs that it’s gone off. Some common indicators include:

  • Bad smell: If the tofu emits a sour, pungent, or unpleasant odor, it’s likely spoiled and should be discarded.
  • Signs of mold: Visible mold growth on the tofu’s surface is a clear sign of spoilage. Do not consume the tofu if you spot any mold.
  • Change in colour: A change in color, such as yellowing or dark spots, may indicate that the tofu is no longer fresh.

If you notice any of these signs, its a good idea to throw it away to avoid any potential health risks.

How To Make Tofu Last Longer?

So, there are a few ways to make tofu last longer, and below, we have laid out these methods for both unopened and opened tofu packages, ensuring you can make it last longer while still maintaining its freshness and quality.

Unopened Tofu


  • Place in the refrigerator: Store the unopened tofu package in the refrigerator at a temperature between 34-40°F (1-4°C).
  • Monitor the expiry date: Keep an eye on the expiry date mentioned on the package and consume the tofu before it expires.


  • Store in the freezer: Place the unopened tofu package in the freezer, ideally at a temperature of 0°F (-18°C) or lower.
  • Thaw before use: When you’re ready to use the tofu, remove it from the freezer and allow it to thaw in the refrigerator for several hours or overnight. Drain any excess liquid and prepare the tofu according to your recipe.

Opened Tofu


  • Drain the liquid: Remove any excess liquid from the opened tofu.
  • Place in an airtight container: Put the tofu in an airtight container.
  • Submerge in water: Cover the tofu completely with fresh, cold water.
  • Seal the container: Close the container with an airtight lid.
  • Store in the refrigerator: Place the airtight container with tofu in the refrigerator at a temperature between 34-40°F (1-4°C).
  • Change the water daily: To ensure the best quality, change the water in the container every day. This prevents bacterial growth and keeps the tofu fresh.


  • Drain the liquid: Remove any excess liquid from the opened tofu.
  • Wrap in plastic wrap or freezer-safe bags: Wrap the tofu tightly in plastic wrap or place it in a freezer-safe bag to protect it from freezer burn and contamination.
  • Label and date: Label the package with the date and type of tofu to help keep track of its storage time.
  • Store in the freezer: Place the wrapped tofu in the freezer, ideally at a temperature of 0°F (-18°C) or below.
  • Thaw before using: When you’re ready to use the tofu, transfer it to the refrigerator to thaw for several hours or overnight. Alternatively, you can use the microwave’s defrost function for quicker thawing.

By following these refrigeration and freezing techniques for both unopened and opened tofu, you can make your tofu last longer while maintaining its quality and freshness.


While expiry dates serve as useful guidelines, they are not absolute indicators of tofu’s safety or freshness. Always inspect the tofu for signs of spoilage and use your judgment before consuming it.

As mentioned, proper storage can help extend the shelf life of tofu. Just remember, if in doubt, it’s better to be safe than sorry!
