Kale chips. The crunchy, healthy, and surprisingly addictive snack that has taken the health food world by storm. But not all kale chips are created equal. The secret to achieving that perfect crispy texture and delicious flavor lies in choosing the right type of kale. So, which variety reigns supreme when it comes to transforming leafy greens into irresistible chips? Let’s dive into the world of kale and uncover the best contenders for your next batch of homemade kale chips.
Understanding Kale Varieties for Chip Perfection
Kale, a member of the Brassica family, is a nutritional powerhouse packed with vitamins, minerals, and antioxidants. It comes in various shapes, sizes, textures, and flavors. While any type of kale can technically be made into chips, certain varieties consistently deliver superior results. Factors like leaf thickness, texture, and inherent bitterness play a significant role in the final outcome.
Curly Kale: The Classic Choice
Curly kale is perhaps the most recognizable type of kale. Its tightly ruffled leaves and vibrant green color make it a staple in many grocery stores. While it’s readily available and affordable, curly kale can be a bit more challenging to transform into perfectly crispy chips.
Curly kale’s texture is naturally tougher and more fibrous than other varieties. This means it requires a bit more effort to massage and prepare properly. If not massaged adequately, the leaves can remain slightly chewy even after baking, which is not the desired outcome for crispy chips. The deep crevices in the leaves can also trap moisture, hindering the crisping process.
However, with the right technique, curly kale can still produce delicious chips. Proper washing and thorough drying are essential. Massaging the leaves with olive oil helps to break down the fibers and tenderize them. Using a slightly longer baking time at a lower temperature can also help to ensure that the chips are crispy without burning.
Dinosaur Kale (Lacinato or Tuscan Kale): The Crispy Champion
Dinosaur kale, also known as Lacinato or Tuscan kale, is often considered the gold standard for making kale chips. Its dark green, almost blue-green, leaves have a unique wrinkled texture and a slightly milder, sweeter flavor than curly kale.
The relatively flat, elongated leaves of dinosaur kale offer several advantages when it comes to making chips. They are easier to wash and dry thoroughly, minimizing the risk of trapped moisture. The thinner texture of the leaves also allows them to crisp up more evenly and quickly in the oven.
Dinosaur kale also has a slightly lower moisture content compared to curly kale. This means it requires less baking time and is less prone to becoming soggy. The result is often a batch of incredibly crispy, flavorful kale chips with a delightful crunch.
Red Russian Kale: A Touch of Sweetness and Color
Red Russian kale is characterized by its flat, fringed leaves and distinctive reddish-purple stems. Its flavor is slightly sweet and peppery, making it a unique addition to kale chips.
While Red Russian kale can be used for making chips, it tends to be slightly more delicate than dinosaur kale. The leaves can be prone to burning if not monitored carefully during baking. The stems, while edible, can also be a bit tougher and may not crisp up as well as the leaves.
To make successful kale chips with Red Russian kale, it’s important to remove the tough stems and focus on the leaves. A shorter baking time at a lower temperature is recommended to prevent burning. The slightly sweet and peppery flavor of this variety can add a delightful twist to your kale chip creations.
Baby Kale: Convenience and Tenderness
Baby kale is essentially young kale leaves that are harvested before they fully mature. It’s typically sold in pre-washed bags and is prized for its tender texture and mild flavor.
Baby kale can be a convenient option for making kale chips, especially if you’re short on time. The leaves are already washed and chopped, saving you prep time. However, because the leaves are so tender and delicate, they can easily burn during baking.
When using baby kale, it’s crucial to monitor the chips closely and reduce the baking time accordingly. A very light coating of olive oil and a low oven temperature are recommended to prevent burning. Baby kale chips tend to be thinner and more fragile than chips made from mature kale leaves.
Key Factors for Perfect Kale Chips, Regardless of Variety
Regardless of the type of kale you choose, several key factors contribute to achieving perfect, crispy kale chips every time. Proper preparation, even distribution of oil, and optimal baking conditions are crucial for success.
Preparation is Paramount
Washing the kale thoroughly is the first step. Remove any dirt, grit, or debris from the leaves. After washing, it’s essential to dry the kale completely. Excess moisture is the enemy of crispy kale chips. Use a salad spinner or pat the leaves dry with paper towels. For curly kale, pay special attention to drying the crevices in the leaves.
Removing the tough stems is another important step. The stems can be bitter and don’t crisp up as well as the leaves. Simply run your fingers down the stem to strip off the leaves.
Once the kale is washed, dried, and stemmed, cut or tear the leaves into bite-sized pieces. Uniformly sized pieces will ensure even cooking.
The Oil Factor
Olive oil is a popular choice for making kale chips, but other oils like avocado oil or coconut oil can also be used. The key is to use enough oil to lightly coat the leaves without making them greasy.
Massaging the kale with the oil helps to distribute it evenly and break down the fibers, resulting in more tender and crispy chips. Don’t be afraid to get your hands dirty and really work the oil into the leaves.
Baking for Crispness
Preheat your oven to a low temperature, typically between 300°F and 325°F (150°C and 160°C). A lower temperature allows the kale to dry out and crisp up slowly without burning.
Spread the kale leaves in a single layer on a baking sheet lined with parchment paper. Overcrowding the baking sheet will prevent the kale from crisping properly.
Bake for 10 to 20 minutes, depending on the type of kale and the oven temperature. Keep a close eye on the chips and rotate the baking sheet halfway through to ensure even cooking. The chips are done when they are crispy and slightly browned around the edges.
Flavor Enhancements: Beyond Salt and Pepper
While salt and pepper are classic seasonings for kale chips, there are endless possibilities for adding flavor and creating unique variations. Experiment with different spices, herbs, and seasonings to find your favorite combinations.
Nutritional yeast adds a cheesy, savory flavor to kale chips, making them a popular vegan snack. Garlic powder, onion powder, paprika, and chili powder are all great options for adding depth and complexity.
Herbs like dried oregano, thyme, and rosemary can also be used to season kale chips. For a touch of sweetness, try adding a sprinkle of maple syrup or a drizzle of balsamic vinegar before baking.
You can even create spicy kale chips by adding a pinch of cayenne pepper or a dash of hot sauce. The possibilities are endless, so get creative and experiment with different flavor combinations.
Storing Your Crunchy Creations
Once your kale chips are baked and cooled, it’s important to store them properly to maintain their crispness. An airtight container is essential for preventing the chips from becoming soggy.
Store the kale chips in a cool, dry place away from direct sunlight. If you live in a humid climate, you may want to add a silica gel packet to the container to absorb excess moisture.
Kale chips are best enjoyed within a few days of baking. Over time, they tend to lose their crispness, even when stored properly.
Troubleshooting Common Kale Chip Problems
Despite your best efforts, sometimes kale chips don’t turn out as expected. Here are some common problems and how to fix them:
Soggy Chips: This is usually caused by excess moisture or overcrowding the baking sheet. Make sure to dry the kale thoroughly and spread the leaves in a single layer.
Burnt Chips: This can be caused by baking at too high a temperature or for too long. Lower the oven temperature and monitor the chips closely.
Chewy Chips: This is often due to not massaging the kale enough or not baking it long enough. Massage the kale thoroughly with oil and increase the baking time if needed.
Bland Chips: This can be easily fixed by adding more seasoning. Experiment with different spices, herbs, and seasonings to find your favorite flavor combinations.
Conclusion: The Quest for the Perfect Kale Chip Ends Here

Its flat leaves, tender texture, and mild flavor make it ideal for creating crispy, delicious kale chips. However, with proper preparation and technique, you can also make excellent chips with curly kale, Red Russian kale, or even baby kale. The key is to focus on thorough drying, even oil distribution, and optimal baking conditions. Don’t be afraid to experiment with different seasonings and flavor combinations to create your own signature kale chip recipe. So, grab a bunch of your favorite kale, preheat your oven, and get ready to enjoy a batch of healthy and addictive homemade kale chips!
What varieties of kale are best suited for making crispy kale chips?
Curly kale, also known as Scotch kale, is generally considered the best variety for making crispy kale chips. Its ruffled leaves have a larger surface area, which allows for more even coating with oil and seasonings. The inherent texture of curly kale also contributes to a satisfyingly crispy chip when baked or dehydrated.
While other kale varieties like Lacinato (dinosaur kale) and Red Russian kale can also be used, they may not achieve the same level of crispiness. Lacinato kale tends to be thinner and can become brittle, while Red Russian kale has a slightly more peppery flavor that might not be ideal for all palates. Experimenting with different varieties can be fun, but for a consistently crispy result, curly kale is the recommended choice.
How does the size of the kale pieces affect the crispiness of the final kale chips?
The size of the kale pieces significantly impacts the crispiness of your kale chips. Large pieces might not dry out completely in the oven or dehydrator, resulting in some areas remaining chewy or soggy. This is because the moisture in the thicker parts of the leaf takes longer to evaporate, preventing uniform crisping.
Aim for pieces that are roughly 1-2 inches in size after removing the tough stems. This allows for even distribution of heat and seasoning, ensuring that each chip is thoroughly dehydrated and crispy. Consistent sizing also contributes to a more uniform cooking time, preventing some chips from burning while others remain undercooked.
What is the ideal oven temperature for baking crispy kale chips?
The ideal oven temperature for baking crispy kale chips is typically between 300°F (150°C) and 350°F (175°C). Baking at a lower temperature allows the kale to dry out slowly and evenly, resulting in a crispier texture. A higher temperature might cause the kale to burn before it fully dehydrates, leading to uneven cooking and a bitter taste.
Keep a close eye on the kale chips as they bake, as oven temperatures can vary. Check for doneness around 10-15 minutes, and adjust the baking time accordingly. The chips are ready when they are crisp to the touch and slightly shrunken in size. Avoid overcrowding the baking sheet, as this can trap moisture and prevent proper crisping.
Does the type of oil used influence the crispiness and flavor of kale chips?
Yes, the type of oil you use significantly affects both the crispiness and the flavor of your kale chips. Oils with a high smoke point, such as avocado oil, coconut oil, or grapeseed oil, are excellent choices because they can withstand higher temperatures without breaking down or developing a burnt flavor. These oils also tend to create a more even crisp and prevent the kale from becoming soggy.
Olive oil, while a popular and healthy option, has a lower smoke point and can impart a stronger flavor. If using olive oil, be sure to monitor the kale chips closely to prevent burning. Ultimately, the best oil for your kale chips depends on your personal preference and the flavor profile you’re aiming for. Experimenting with different oils can lead to some delicious discoveries.
How important is it to thoroughly dry the kale before making kale chips?
Thoroughly drying the kale before making kale chips is absolutely crucial for achieving a crispy result. Excess moisture will steam the kale in the oven instead of allowing it to crisp up, resulting in soggy or limp chips. Water also prevents the oil and seasonings from adhering properly to the leaves, leading to uneven flavoring.
After washing the kale, use a salad spinner to remove as much water as possible. Then, spread the kale leaves out on a clean kitchen towel or paper towels and gently pat them dry. Make sure both sides of the leaves are dry to the touch before proceeding with the oil and seasoning. Patience in this step will pay off with perfectly crispy kale chips.
What are some common mistakes that prevent kale chips from becoming crispy?
One of the most common mistakes is overcrowding the baking sheet. This traps moisture and prevents the kale from drying out evenly, leading to soggy chips. Another error is using too much oil. While oil is necessary for crisping, excessive amounts can make the kale greasy and heavy, hindering the dehydration process.
Furthermore, using a too-high oven temperature can cause the kale to burn before it fully dries, resulting in a bitter taste and uneven texture. Finally, failing to remove the tough stems from the kale leaves can leave you with chewy, unpleasant pieces in your batch of chips. Avoiding these pitfalls will greatly improve your chances of achieving perfectly crispy kale chips every time.
Can kale chips be made in a dehydrator instead of an oven, and how does the process differ?
Yes, kale chips can absolutely be made in a dehydrator. In fact, many people find that a dehydrator produces even crispier kale chips than an oven because it operates at a lower, more consistent temperature. This gentle dehydration process allows the moisture to evaporate slowly and evenly, resulting in a perfectly crisp and delicate texture.
The process differs primarily in temperature and time. Instead of baking at 300-350°F, you’ll typically dehydrate kale chips at around 135°F (57°C) for 4-8 hours, or until they are completely dry and crispy. Arrange the kale leaves in a single layer on the dehydrator trays, ensuring that they are not overlapping. No preheating is required, and you don’t need to flip the leaves during the dehydration process. The dehydrator does all the work for you, resulting in a consistently crispy batch of kale chips.
