How To Save Kale? A Comprehensive Guide to Preservation
To save kale, the most effective methods are freezing (after blanching to preserve quality), dehydrating for kale chips or powder, and pickling for a tangy, long-lasting treat. Choose the method that best suits your intended use of the kale.
Introduction: The Versatility of Kale and the Importance of Preservation
Kale, a nutritional powerhouse and culinary chameleon, has surged in popularity over the past decade. From smoothies and salads to chips and stir-fries, its versatility knows few bounds. However, its short shelf life can be frustrating. Wilted, slimy kale is a common kitchen tragedy. Knowing how to properly preserve kale allows you to enjoy its benefits year-round, reduce food waste, and unlock a world of culinary possibilities. This guide provides a comprehensive overview of the best methods for saving kale, ensuring you always have this leafy green at your fingertips.
The Nutritional Powerhouse: Why Save Kale?
Kale isn’t just a trendy vegetable; it’s packed with essential nutrients. Preserving kale ensures you retain access to these benefits even when it’s not in season or readily available fresh.
- Vitamins: Kale is exceptionally rich in vitamins A, C, and K.
- Minerals: It provides significant amounts of calcium, potassium, and magnesium.
- Antioxidants: Kale is loaded with antioxidants, which help protect your body from damage caused by free radicals.
- Fiber: Its high fiber content aids digestion and promotes feelings of fullness.
Consuming kale regularly can contribute to improved bone health, immune function, and overall well-being.
Freezing Kale: The Most Common and Versatile Method
Freezing is arguably the most practical way to save kale, allowing you to store large quantities for extended periods. The key to successful freezing is blanching. Blanching stops enzyme activity that can cause deterioration in flavor, color, and texture.
The Freezing Process:
- Wash: Thoroughly wash the kale leaves to remove any dirt or debris.
- Cut/Tear: Cut or tear the kale into bite-sized pieces. Remove any tough stems.
- Blanch: Submerge the kale in boiling water for 2-3 minutes. Immediately transfer to an ice bath to stop the cooking process.
- Drain and Dry: Drain the kale well and pat it dry with paper towels. Excess water can lead to ice crystals and freezer burn.
- Freeze: Spread the kale in a single layer on a baking sheet lined with parchment paper. Freeze for a few hours until solid.
- Store: Transfer the frozen kale to freezer bags or airtight containers. Label with the date.
Frozen kale is best used in cooked dishes like soups, stews, smoothies, and stir-fries.
Dehydrating Kale: Creating Crispy Kale Chips and Versatile Kale Powder
Dehydrating kale is a fantastic way to create crispy kale chips or to turn kale into a nutritious powder for smoothies and other recipes.
The Dehydrating Process:
- Wash and Dry: Wash the kale leaves and thoroughly dry them.
- Massage (Optional): Massaging the kale with a little olive oil and salt enhances flavor and crispness.
- Arrange: Arrange the kale leaves in a single layer on dehydrator trays.
- Dehydrate: Dehydrate at 135°F (57°C) for 4-6 hours, or until the kale is crispy.
- Cool and Store: Let the kale cool completely before storing in an airtight container.
To make kale powder, simply grind the dehydrated kale in a food processor or blender until it reaches a fine consistency. Store in an airtight container in a cool, dark place.
Pickling Kale: A Tangy and Unique Preservation Method
Pickling kale is less common than freezing or dehydrating, but it offers a unique way to preserve its flavor and add a tangy twist to your meals.
The Pickling Process:
- Prepare the Kale: Wash and chop the kale into desired sizes.
- Make the Brine: Combine vinegar (white, apple cider, or rice vinegar work well), water, sugar, salt, and spices (such as garlic, peppercorns, and red pepper flakes) in a saucepan. Bring to a boil.
- Pack the Kale: Pack the kale into sterilized jars, leaving some headspace.
- Pour the Brine: Pour the hot brine over the kale, ensuring the kale is fully submerged.
- Seal and Process (Optional): Seal the jars tightly. For longer shelf life, process the jars in a boiling water bath for 10 minutes. If not processing, refrigerate immediately.
Pickled kale is a great addition to sandwiches, salads, and charcuterie boards.
Common Mistakes to Avoid When Saving Kale
- Not Blanching Before Freezing: This leads to a loss of flavor, color, and texture.
- Not Drying Kale Thoroughly: Excess moisture results in ice crystals and freezer burn.
- Over-Dehydrating Kale: Kale chips can become brittle and bitter if dehydrated for too long.
- Using Too Much Salt: Salt can draw moisture out of kale, resulting in soggy chips.
- Not Sterilizing Jars Properly: This can lead to spoilage when pickling.
- Storing Kale in a Damp Environment: This can cause mold growth.

Frequently Asked Questions (FAQs)
Can you freeze kale without blanching?
While you can freeze kale without blanching, the quality will be significantly reduced. Unblanched kale is more likely to become bitter and have a less appealing texture after thawing. Blanching is highly recommended for optimal results.
How do you properly wash kale before saving it?
Submerge the kale leaves in a bowl of cold water. Gently agitate the leaves to remove dirt and debris. Rinse thoroughly under running water. For extra cleaning, consider adding a small amount of vinegar to the water.
Can you freeze curly kale vs. lacinato (dinosaur) kale differently?
The freezing process is the same for both curly kale and lacinato kale. However, lacinato kale tends to be less fibrous and may require slightly less blanching time. The key is to ensure both types are thoroughly washed, dried, and blanched appropriately.
What is the best type of vinegar for pickling kale?
White vinegar, apple cider vinegar, and rice vinegar are all excellent choices for pickling kale. White vinegar provides a clean, tangy flavor, while apple cider vinegar offers a slightly sweeter and more complex taste. Rice vinegar is milder and more delicate. Choose the vinegar that best suits your personal preference.
How can I prevent my kale chips from becoming soggy?
Ensure the kale is completely dry before dehydrating. Avoid using too much oil or salt. Spread the kale leaves in a single layer on the dehydrator trays, ensuring good airflow. Also, store your dehydrated kale chips in an air-tight container to prevent moisture absorption.
Is it safe to eat kale that has freezer burn?
While freezer burn doesn’t make food unsafe to eat, it can affect the taste and texture of the kale. Freezer-burned kale may be drier and less flavorful. It is generally safe to consume, but you may want to trim off the affected areas before using it.
Can I use frozen kale directly in smoothies?
Yes, frozen kale can be added directly to smoothies. It can even enhance the smoothie’s texture, making it thicker and colder. Just ensure that the frozen kale is broken into smaller pieces before adding it to the blender.
How long does dried kale powder last?
Dried kale powder can last for up to a year or even longer if stored properly in an airtight container in a cool, dark, and dry place. However, it’s best to use it within 6-12 months for optimal flavor and nutritional value.
What are some creative ways to use pickled kale?
Pickled kale is a versatile ingredient that can be used in a variety of dishes. Try adding it to sandwiches, salads, wraps, and charcuterie boards. It can also be used as a topping for pizzas or as a flavorful addition to stir-fries. The tangy flavor of pickled kale complements a wide range of foods.
Can I rehydrate dehydrated kale for cooking?
While you can technically rehydrate dehydrated kale, it is not recommended. Rehydrated kale will not regain its original texture and may become mushy. It’s best to use dehydrated kale as kale chips or to grind it into powder for adding to smoothies and other recipes.
Is organic kale better for preserving?
Whether organic kale is “better” for preserving is a matter of personal preference. Organic kale is grown without synthetic pesticides and fertilizers, which some people prefer. However, both organic and conventionally grown kale can be preserved using the methods outlined in this guide. Ensure whichever you choose is washed thoroughly.
How do I know if my pickled kale has gone bad?
Look for signs of spoilage such as a bulging lid, cloudy brine, or an off-putting odor. If the kale looks or smells unusual, it’s best to discard it. Proper sterilization of jars and adherence to pickling recipes are essential for preventing spoilage.
