While okonomiyaki is delicious, chances are you won’t eat it every week, and the sauce has limited uses.

That’s why many have asked, “How long does the sauce last?”

Let’s dig into the shelf-life that a little more because you have the storebought, unopened, or your homemade sauce.

How long does okonomiyaki sauce last

An unopened bottle of okonomiyaki sauce can last for up to four years in your pantry. Once it’s opened, store it in the refrigerator and used it within 6 months of opening. A homemade okonomiyaki sauce can be stored for up to two weeks after making.

Does okonomi sauce need to be refrigerated?

Okonomiyaki sauce is processed to be stable on the shelf even when opened and ingredients like the vinegar and salt in sauce help keep it up to 8 weeks in a dark pantry at room temperature, but keeping it in the refrigerator can extend that to 6 months.

You can store okonomiyaki sauce in the fridge door so you’ll still have plenty of space for the most perishable foods like milk and meat.

There are a lot of preservatives in the store-bought sauces, so they don’t need to be kept as cool, but make sure your fridge is set to 40 Fahrenheit or below.

How to store homemade okonomiyaki sauce

You should store homemade okonomiyaki sauce in an airtight container or mason jar so it keeps fresh the longest. You can store okonomiyaki sauce with fresh ingredients for two weeks after making, but making sauce just mixing other sauces can last up to 2 months.

I’ve seen a lot of sauces that combine just other sauces to prepare so those could last a lot longer in the fridge.

If you’re careful with how you use it (clean spoons to scoop it out only!), it should last for a month in the refrigerator.


There you have it, you can store okonomiyaki sauce just like any other condiment in your pantry.

It can live to be used another day, so you don’t have to finish it in a rush.
