Learn the easiest way to freeze fresh spinach to prevent food waste—and use later in smoothies, baked goods, and easy meals!


How to Freeze Spinach

We always keep a stash of frozen spinach on hand to use in everything from smoothies to muffins and soups. It’s awesome since you never have to worry about it going bad, there’s always some ready and waiting for you, and the nutrients are locked in at the moment of freezing.

Oh: And it’s so crazy easy without any involved steps or processing!

You can do this with regular or baby spinach. I prefer to use prewashed baby spinach from the store simply because it’s easiest.

Ingredients Needed to Freeze Spinach

To freeze spinach, all you’ll need is:

  • Fully washed and dried spinach (you can also feel free to use less).
  • A zip top freezer bag (I recommend the gallon size, but you could also use multiple quart size bags).

How to Freeze Spinach Step-by-Step

The freezing spinach process is a simple one, and it’s a great way to keep spinach for way longer than it lasts in the fridge. Follow these steps to freeze spinach (and find the detailed recipe below):

  1. Add spinach to the freezer bag, making sure it’s completely dry to avoid ice crystals.
  2. Press bag to release as much air as possible, and seal.
  3. Freeze overnight, and you’re done!

TIP: You can crush up the frozen leaves to make it easy to measure out to use in recipes if you like.

Recipes that Use Frozen Spinach

Here are some of my go-to kid-friendly recipes for using frozen spinach. For all of them, add the frozen spinach directly to the recipe without thawing it first.

TIP: You can also add frozen spinach to soups like Minestrone, pretty much any pasta recipe, or any smoothie recipe you like.

Best Tips for Freezing Spinach

  • Spinach can stay frozen for up to a year.
  • Do smaller amounts of spinach if desired.
  • You can do this with regular or baby spinach. I prefer to use prewashed baby spinach from the store simply because it’s easiest.
  • Make sure that the leaves are fully dried to prevent ice crystals in the bag. (It’s honestly okay if there are some though!)
  • Use gallon or quart size freezer bags according to your preference.

    Thank you for this simple suggestion! We froze the large package of costco spinach, and it has saved us from so much food waste. We don’t love plain spinach in a salad, but like to add it to smoothies, spinach muffins, eggs etc. Having it frozen works great!

    1. I think frozen fresh spinach is easier to use and tastes better in smoothies vs store bought frozen spinach, which has often been cooked and has a stronger flavor. Plus, it’s a nice way to make sure it doesn’t go bad if you don’t use it all fresh!
