Absolutely, you can freeze avocados for smoothies. This is a great way to extend the shelf-life of ripe avocados and have them readily available for your smoothie preparations. Here's how to do it: Cut the avocado in half and remove the pit. Scoop out the flesh with a spoon. If you plan to freeze for an extended period, consider adding a little lemon or lime juice to prevent browning. Place the scooped avocado into a resealable bag or container. If using a bag, try to remove as much air as possible before sealing. Store it in the freezer. Frozen avocado should maintain good quality for about 4-6 months. When ready to use, you can directly add your frozen avocado to the blender for your smoothie. No need to thaw! It gives a lovely creamy texture to your smoothie.
