**Panko breadcrumbs** bring a *light* and *crispy* texture loved in many dishes.

As with any food product, it’s essential to know how to properly store and handle them to ensure their quality and safety. 

One common question that arises is whether or not panko bread crumbs go bad. We’ll explore the shelf life of panko bread crumbs, how to tell if they’ve gone bad, and best practices for storing them.

How Long Do Panko Bread Crumbs Last?

Panko bread crumbs [1] have a relatively long shelf life and typically last several months if stored properly. 

Unopened packages of panko bread crumbs can last up to a year past the “best by” date on the packaging if stored in a cool, dry place away from direct sunlight. 

Once the package has been opened, transferring the remaining bread crumbs to an airtight container is essential to prevent moisture from getting in. 

Open panko bread crumbs can last up to six months when stored correctly in a cool, dry place. Plus, using your senses to determine if they’ve gone bad before using them in a recipe is always essential.

Can You Freeze Them?

Yes, panko bread crumbs can be frozen to extend their shelf life. To freeze them, transfer the bread crumbs to an airtight container or freezer bag and place them in the freezer. 

“Carbohydrates, and especially refined ones like sugar, make you produce lots of extra insulin. I’ve been keeping my intake low ever since I discovered this. I’ve cut out all starch such as potatoes, noodles, rice, bread, and pasta.”

– Cynthia Kenyon, American Molecular Biologist

Frozen panko bread crumbs can last up to a year, but they should be used for the best quality within six months. When ready, thaw the bread crumbs in the refrigerator overnight before using them in a recipe. 

It’s important to note that freezing may affect the texture and crispiness of the bread crumbs, so they may not be suitable for all recipes after freezing.

  5. Use your senses: Before using panko bread crumbs in a recipe, sniff them to ensure they don’t smell rancid or off. You can also check for any visible mold or discoloration. If you notice any of these signs, it’s best to discard the bread crumbs and use a fresh batch.


Is it OK to use expired panko bread crumbs?

Using expired panko bread crumbs is not recommended, as they may have lost their flavor and texture and could also pose potential food safety risks.

Consuming expired bread crumbs could result in digestive issues, such as upset stomach, vomiting, and diarrhea. But is it okay to use flour instead of bread crumbs?

What is panko made of?

Panko is a type of breadcrumb that originated in Japan. It is made from bread without crusts, processed into large flakes rather than the small crumbs typically found in Western-style breadcrumbs. 

Panko bread crumbs are made from a specific type of bread that is baked using an electric current, resulting in a lighter and airier texture than traditional breadcrumbs. 

In Conclusion

Panko bread crumbs can go bad over time, especially if not stored properly. Signs of spoilage include off smells, discoloration, and the presence of mold. 

To ensure the freshness and quality of your panko bread crumbs, store them in an airtight container in a cool, dry place away from direct sunlight. 

Panko bread crumbs should not be refrigerated and should be used before the expiration date for optimal flavor and texture. 

If you have any doubts about the safety of your panko bread crumbs, it’s best to discard them and use a fresh batch to avoid any potential food safety risks.
