How to Keep Tofu Fresh for Months After Opening

Whether you're a vegetarian, vegan, or simply seeking more plant-based meals, tofu is an excellent and protein-rich choice. Tofu's highly absorbent nature allows it to soak up flavors from marinades, sauces, and spices. There are numerous ways to prepare tofu depending on its firmness—frying, grilling, baking, air frying, or even pressure cooking are all great options based on the texture and flavor you're aiming for. But before you dive into cooking, it's crucial to know how to properly store tofu to maintain its freshness. Here's how to ensure tofu stays fresh and tasty.

Storing Tofu in the Refrigerator

Surprisingly, unopened tofu in its original packaging only lasts 3 to 5 days, which is even shorter than when you open it and store it in the fridge. If your tofu is in airtight packaging, you can use it before the labeled expiration date. However, if your tofu is submerged in water, it's wise to create your own storage method to extend its shelf life. To do so, open the tofu package and transfer it into a food storage container with a lid. Cover the tofu completely with cold water and seal the container tightly. To keep the tofu fresh and hydrated, change the water daily. With this method, your tofu can last up to a week in the refrigerator.

How to Properly Store Leftover Tofu

As with most food, the sooner you consume your leftover tofu, the fresher it will taste. Cooked tofu can be stored for up to 5 days in an airtight container in the fridge. However, if you detect a sour smell, it’s a sign that the tofu has spoiled and should be discarded.

How to Freeze Tofu

You can freeze nearly all types of tofu, but firm and extra firm varieties are best because they hold their texture and flavor well after freezing. To properly freeze tofu, follow the steps outlined below:

1. To prepare tofu for freezing, gently blot it with a paper towel to remove any excess moisture. You can freeze a whole block of tofu or slice it into small cubes. 
2. Place the tofu on a baking sheet and freeze it overnight.
3. Once frozen, transfer the tofu to an airtight container or a freezer-safe bag. When stored in this manner, tofu can last up to 5 months. 

When you're ready to use your frozen tofu, let it thaw in the fridge overnight. If you're in a rush, run cold water over the tofu for a few minutes until fully thawed, then pat it dry before cooking to remove any remaining moisture.

Frozen tofu performs just as well as fresh tofu, especially when pan-fried to create dishes like Crispy Peanut Tofu With Sugar Snap Peas and Peppers. You can also grill frozen tofu for a lighter, flavorful dinner option.

How Long Can Tofu Be Stored?

Tofu kept in the fridge will last up to a week if you change the water daily. When stored in the freezer, tofu can remain good for up to 5 months.

Frequently Asked Questions

• How should you store tofu once opened?

  If you’ve opened a package of tofu and don’t plan on using it right away, simply place it in a container with fresh, cold water and cover it with a lid. Opened tofu can last up to 7 days in the refrigerator, but remember to change the water daily to maintain its freshness and moisture.

• Can tofu be stored without water?

  Tofu should always be kept in clean, fresh water unless it's unopened and sealed in its original packaging. The water helps prevent bacteria and keeps the tofu moist for longer periods.
