How can I freeze bananas for smoothies to ensure they stay fresh and ready to use whenever I need them?

To freeze bananas for smoothies, peel and slice them, then place the slices on a baking sheet lined with parchment paper. Freeze the slices for about 1-2 hours until they are firm, then transfer them to a resealable plastic bag or airtight container. This method prevents the slices from sticking together and allows you to easily grab the amount you need for your smoothie. Stored in the freezer, the bananas will stay fresh and ready to use whenever you need them.
