Frozen veggies that are ready to be added to meals are incredible time savers. Having components ready to go to add to dinners or smoothies helps make your day just a little bit easier. 

Of course, you can buy frozen spinach. But if your garden is producing more than you can eat, or you have a bag in the fridge you won’t be able to finish, freezing your own spinach helps reduce waste and saves money. It’s a great tool to have in your easy healthy meal prep arsenal.

Is frozen spinach as good as fresh spinach?

Maybe. It depends on how you want to use it. You cannot freeze spinach and expect to use it in a salad or for other recipes where it needs to be fresh and whole.

There is some loss of nutrients with blanching, but freezing spinach at the peak of freshness is still healthier than eating out of season spinach trucked in from 1,500 miles away.

do you blanch spinach before freezing?

Maybe. It depends on how you want to use it. 

If you plan to use the frozen spinach within a few weeks, there is no need to blanch it first.

But unblanched spinach left in the freezer too long will turn brown because of enzyme actions which will change the texture, flavor, and coloring.

how long do you blanch spinach for freezing?

The spinach just needs two minutes in boiling water for the blanching process.

freezing spinach for smoothies

If you’re planning on using your spinach for smoothies, you can blend it in a food processor or blender with a splash of water until it is a puree. I find it easiest to freeze in ice cube trays or silicone trays for smaller and easy to blend portions. I’ve even used these silicone egg molds that are for making Instant Pot Egg Bites.

How to Blanch Spinach
  1. Wash spinach, discarding old leaves and woody stems.

How to Freeze Spinach (Blanched)
  1. Squeeze excess water out of the spinach (I squeeze portions in my hand over the strainer).

  2. Transfer to freezer containers or a muffin pan lined with parchment paper liners.

  3. Freeze for 3 hours. If using the muffin pan method, transfer to freezer bags once spinach has frozen solid.

Freezing Spinach for Smoothies

There is no need to thaw the spinach before adding it to soups or sauces.

 

5 oz of spinach will wilt down to about 1 cup for freezing.
