How to Freeze Spinach

Leafy greens have some pretty amazing superpowers, nutritionally speaking, yet they don’t stay fresh for long. I’m going to show you two different methods for freezing spinach (or any other leafy green) to give your greens 10x the shelf life! Never let that beautiful bag of fresh spinach go to waste again.

Now I know we’ve all been there. You buy that big beautiful bag of greens, lovingly place it in your fridge and vow to eat it for daily lunches and smoothies. Two weeks later you’re digging through that fridge only to find a bag of gross, wilted mush that once resembled spinach. This was definitely me when I first started drinking green smoothies. I knew I needed a better way to store my leafy greens. These two quick methods do exactly that!

How to Freeze Spinach

Following these simple steps can literally make your spinach (and other leafy greens) last 10x longer. Pick the method you like best and go crazy!

Freezing Greens Method #1: Cubes

Try to use as many fresh leafy greens as possible, yet if they’re getting close to the expiration date then make these cubes.

1. Blend 2 cups of leafy greens (about two handfuls) in a blender with 1/2 cup liquid (preferably water, but a touch of lemon juice can help). It’s done when it reaches a juice-like consistency. The goal is no leafy chunks!
2. Pour contents into an ice cube tray, then freeze. Make sure the tray is level in the freezer.
3. Store the frozen cubes in a freezer-safe container. I use gallon silicone ziplock bags for zero freezer burn.

You can follow these same steps for kale, chard, romaine, cabbage, and even herbs. I don’t typically recommend adding ice to your smoothies because it dulls your blender blades, as well as causes the motor to work extra hard, yet this cube recipe is the exception to the rule.

Freezing Greens Method #2: Storage Bags

For this method, gather the following items: fresh spinach, dish towels, paper towels, freezer-safe bags or containers and a sharpie.

1. Prepare spinach by washing and drying. Pack the spinach into freezer-safe bags or containers. You can pack the spinach tightly. Label bag or container with date. If a precise amount (such as for a recipe) for the spinach is needed, make sure to add that to the label as well.
2. Place bags or containers in the freezer, allowing for air circulation for proper freezing. If using spinach within a few weeks or months, a standard freezer is sufficient. For longer freezing times, a deep freezer is recommended as it will keep the frozen food at a lower temperature, prolonging its quality. Note that for deep freezing or longer freezer storage times, it may be prudent to double bag the spinach in order to prevent freezer burn.

As the spinach leaves freeze, they will lose a lot of volume due to ice crystals breaking down the cell walls. (For this reason, frozen spinach is also easier to blend when making green smoothies from a freezer pack.) And done! No need to waste spinach any longer.

FAQs

Why Should I Freeze Spinach?

Unless you buy spinach by the cup-full every day for your green smoothie (or pick from your garden), you probably buy it in bunches. Or like me, in Costco-sized bags. It starts out crisp and fresh, yet after only a few days, starts to wilt and smell funky. I used to throw out half bags of spinach all the time because I couldn’t get through it fast enough.

I learned how to freeze fresh spinach because I was sick of wasting money and time on something that didn’t last. Concerned about the loss of nutrition from freezing spinach? Read on.

Fresh vs Frozen Spinach

I often get emails asking about how to use frozen fruit and veggies while still getting the most in the way of nutrients. The truth is, frozen produce is often less expensive than fresh. It’s also frozen at peak freshness, making it even fresher and more nutrient-dense than some of the fresh produce at the grocery store.

My best advice is to buy produce fresh in its season, then freeze it to retain almost all those precious nutrients. Even if you grow your own leafy greens, you can prolong the shelf life by learning how to freeze them properly.
