No more stinky surprises and I always had leafy green vegetables ready to go. Freezing kale is one of those simple, no-brainer kitchen hacks that saves money, saves time, and makes healthy eating feel way more doable.

Step-by-Step Guide

Whether you’re grabbing a bag of kale from the grocery store, shopping at the farmer’s market, or harvesting your own, freezing kale is one of the easiest ways to cut down on prep time and always have greens ready for smoothies, soups, and quick meals. Here’s how to do it step by step:

Two press-lock plastic bags labeled for kale

Take freezer-safe plastic bags and label each one with the quantity using a marker.

Thick kale stems separated from the leafy greens

Wash kale thoroughly and de-stem the kale leaves from the thick stems.

Chop the leaves into medium-sized pieces or leave them whole, depending on how you plan to use them later.

Kale Freezing Tips

Choose fresh, vibrant leaves: Older or yellowing kale leaves don’t freeze as well and can have a stronger, more bitter flavor.
Wash thoroughly: Dirt loves to hide in curly kale, so give it a good rinse before freezing.
Prevent freezer burn: Make sure the spinach is completely dry and moisture free before freezing, remove as much air as possible from the bag, and store it flat in the freezer for an airtight seal.
Flash freeze first: Spread kale on a baking sheet for a few hours before bagging to prevent sticking.
Blanching: Blanching kale before freezing can help preserve color, texture, and nutrients, especially if you plan to use it in cooked dishes.

Does Freezing Kale Lose Its Nutrients?

Freezing kale preserves most of its nutrients, especially if you prep it properly. A tiny amount of water-soluble vitamins, like vitamin C, may decrease slightly, but overall, frozen kale is still packed with fiber, vitamins, and antioxidants.

How to Use Frozen Kale

Once you’ve got your kale stashed in the freezer, meal prep becomes faster and way less stressful. Here’s how I use frozen kale:

In smoothies: Toss frozen kale straight into the blender to make my kale smoothie and kale banana smoothie.
With squash: Stir chopped frozen kale into roasted butternut squash dishes for extra greens. It’s perfect in my Mediterranean spaghetti squash for a quick, flavorful boost.
In gnocchi: Add frozen kale to warm gnocchi dishes for a pop of color and nutrition. I love tossing it into my Tuscan gnocchi for an easy, hearty weeknight meal.
In soup: Add frozen kale to hearty soups like my vegetable barley soup, where its slightly bitter flavor pairs well with savory seasonings.

Common Questions

What is the best way to preserve kale?

The best way to preserve kale depends on how you plan to use it. For short-term storage, keep unwashed leaves dry and cold in the fridge. For longer storage, the freezer is the best place to keep your kale. freezing kale works well, with blanching as an optional step to help preserve color and texture if you plan to cook it later.

Does frozen kale taste different than fresh kale?

Frozen kale can taste slightly different than fresh kale, mainly because freezing softens the leaves. Once thawed or cooked, the texture is less crisp and more tender, which makes it better suited for smoothies, soups, stews, and sautéed dishes rather than salads.

Can I freeze kale in bulk or should I freeze in portions?

It’s best to freeze kale in portions. Spread chopped leaves on a baking sheet to freeze individually before transferring to bags. This prevents clumping and makes it easy to grab just the amount you need.

How long does kale last in a freezer?

Properly frozen kale lasts up to 6 months. For the best taste and nutrient retention, try to use it within this timeframe, keeping it stored in airtight, freezer-safe bags.
