Leafy greens have some pretty amazing superpowers, nutritionally speaking, but they don’t stay fresh for long. I’m going to show you how to freeze spinach (or any other leafy green), and 10x it’s shelf life! Never let that beautiful bag of fresh spinach go to waste again.
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 containers/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.
Simply tossing a bag in the freezer doesn’t help either! The leaves in the middle don’t freeze right, plus freezer burn is always an issue. So I learned how to freeze fresh spinach, because I was sick of wasting money + time on something that didn’t last.

Fresh vs frozen spinach
I often get emails asking about how to use frozen fruit and veggies while still getting the most nutrients. The truth is, frozen produce is often less expensive than fresh. It’s also frozen at peak freshness, making it even fresher + 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.
This spinach freezing hack may not be for everyone, but if you’re planning on blending your greens then I’ve got two words for you: spinach cubes.

How to freeze spinach:
Following these simple steps can literally make your spinach (and other leafy greens) last 10x longer. Try to use as many fresh leafy greens as possible, but if they’re getting close to the expiration date then make these cubes:
- 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!
- Pour contents into an ice cube tray, then freeze. Make sure the tray is level in the freezer.
- Store the frozen cubes in a freezer-safe container. I use gallon silicone ziplock bags for zero freezer burn.
And that’s how to freeze spinach! 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 these cube recipes are the exception to the rule.
