Follow our easy-step-by-step directions on how to freeze spinach for smoothies. Freezing spinach is the best way to keep this nutritious leafy vegetable on hand at all times without worrying it may go bad.
Add spinach and water to the blender. Blend on high until the leaves are pureed. You can add more water if needed.
Pour the pureed spinach into the ice cube tray and freeze for about 3 hours or overnight.
Whole leaves method
Place washed and dried whole spinach leaves into the freezer safe food bags. Seal it leaving a small opening. Insert the straw into the small opening and suck out as much air as possible, creating a vacuum seal.
Mark the bags with the date and freeze until ready to use.
Notes
I like to blend the spinach with water, in case I will be adding it to soups or other savory recipes.
You do not need to blanch spinach before freezing, but blanching can preserve bright color.
No need to thaw frozen spinach, simply add few cubes to the blender with the rest of smoothie ingredients.
