While technically you *can* freeze homemade guacamole, the flavor and texture of the guac will change after freezing. If you still want to proceed despite this warning, I recommend using any of the below mentioned method and freeze for no longer than 3 months. Method 1 : Place the mashed guacamole in freezer zip bag, squeeze out the air completely, close the zip bag, flatten it and freeze. Method 2 : Place the dip in freezer safe container or jar and smooth out the top, pour thin layer of olive oil, cover with lid and freeze. Note : If you plan to freeze guacamole, then I recommend please do not add chopped onion, tomato, jalapeño and cilantro prior to freezing. Just mix the mashed avocado with lime juice, salt, and a bit of minced garlic and freeze. Once you thaw the guac in the refrigerator overnight, add chopped onion, tomato, and cilantro, give it a nice stir and serve.
