Don’t ditch the brine! Pour some of that salty liquid into the bag with the olives before freezing. The brine acts like an anti-freeze for flavor, preventing the olives from turning into bland, flavorless ice cubes.
Can You Freeze Olives - The Food Scribe
Alternatively, you can freeze them in a single layer on a baking sheet first (that’s called “flash freezing”), then transfer them to a bag. This stops them from clumping into one giant olive iceberg. You’re welcome.
How Long Will They Last?
In the freezer, properly stored olives will stay good for up to 6 months. After that, they won’t go bad—but the flavor and texture will start to fade. They’ll become the sad, ghostly version of their former selves.
So, mark your calendar with a cryptic note like “Olive Judgement Day – Check Fridge.” That’s the kind of life advice that changes a person. (It changes me, anyway.)
