Kale chips from the grocery store cost $5-7 for a small bag that disappears in minutes. Making them at home costs a fraction of that price while delivering fresher, crunchier results without preservatives or excessive sodium. The dehydrator method produces the best texture—light, crispy chips that shatter pleasantly between your teeth rather than the unevenly cooked, sometimes burnt results from oven baking.
The secret to exceptional kale chips is low, slow dehydration that removes moisture completely without cooking the leaves. High temperatures destroy nutrients and create bitter flavors, while gentle drying at 125°F preserves the bright green color and sweet, slightly nutty taste of fresh kale. After testing multiple varieties and seasoning combinations, this method produces consistently crispy chips that store well for up to two weeks.
Choosing the Right Kale
Any kale variety works for chips, but textures vary significantly. Curly kale (the most common grocery store variety) creates the crunchiest chips due to its ruffled edges that become lacy and crisp when dried. Lacinato kale (also called dinosaur or Tuscan kale) produces flatter, more delicate chips with a slightly chewier texture. Red Russian kale offers a sweeter flavor but can become brittle.
Select bunches with firm, deeply colored leaves avoiding any yellowing or wilting. Smaller leaves dry more evenly than large, mature leaves which can develop tough central ribs. If your kale has been sitting in the refrigerator for several days, refresh it in ice water for 10 minutes before processing to rehydrate slightly.
Avoid using baby kale or pre-cut bagged kale for chips. These are too small and thin, reducing to paper-thin scraps rather than substantial chips. Whole bunches of mature kale provide the structure needed for satisfying crunch.
For the sweetest flavor, use kale harvested after the first frost. Cold temperatures trigger the plant to convert starches to sugars as a natural antifreeze. Fall and winter kale chips taste noticeably sweeter than summer batches.
Preparation Secrets for Crispiness
Surface moisture is the enemy of crispy kale chips. Any water left on the leaves creates steam during initial drying, resulting in soggy spots that never fully crisp.
Step 1: Remove Stems
Strip leaves from the tough central stems. The stems don’t dry well and create hard, woody bits in your chips. Hold the stem in one hand and strip leaves upward with the other, or use a knife to cut along both sides of the stem.
Step 2: Wash Thoroughly
Kale grows close to the ground and often harbors grit in its curls. Wash in a large bowl of cool water, agitating gently to dislodge debris. Lift leaves out of the water (don’t pour water off, which redeposits grit) and repeat with fresh water if necessary.
Step 3: Dry Completely
This is the most critical step. Use a salad spinner to remove bulk water, then lay leaves on clean kitchen towels in a single layer. Pat with additional towels to absorb remaining moisture. Allow to air dry for 15-20 minutes while you prepare seasonings. Leaves should feel completely dry to the touch before oiling.
Step 4: Size Matters
Tear leaves into pieces slightly larger than your desired chip size—they shrink significantly during drying. Aim for 3-4 inch pieces. Too small, and they become crumbs; too large, and they dry unevenly with chewy centers.
Basic Salt & Oil Recipe
This foundational recipe lets the kale flavor shine through. Master this before experimenting with complex seasonings.
Crispy Kale Chips
Ingredients
- 1 large bunch curly kale (about 8 cups prepared)
- 1 tablespoon extra virgin olive oil or avocado oil
- ¾ teaspoon fine sea salt
- Optional: 2 tablespoons nutritional yeast for cheesy flavor
Instructions
- Remove stems and tear kale into 3-4 inch pieces
- Wash thoroughly and dry completely—this is crucial for crispiness
- Place dried kale in a large bowl
- Drizzle with oil and sprinkle with salt
- Massage oil into every leaf for 1-2 minutes until evenly coated
- Arrange in single layer on dehydrator trays without overlapping
- Dry at 125°F for 4-6 hours until completely crisp
- Cool for 10 minutes before storing
The massage step is essential. Rubbing oil into the leaves breaks down the waxy cuticle slightly, allowing better oil penetration and ensuring every cranny gets coated. Chips with dry spots taste bitter and don’t crisp properly.
Arrange leaves in a single layer with space between them—overlapping creates steam pockets that prevent drying. It’s okay if edges touch slightly, but don’t pile leaves on top of each other. Depending on your dehydrator size, you may need to work in batches.
Creative Seasoning Ideas
Once you master the basic recipe, experiment with these flavor combinations. Apply seasonings along with the oil before drying.
Nacho Cheese: Add 3 tablespoons nutritional yeast, ½ teaspoon garlic powder, and ¼ teaspoon turmeric for color. This is the classic “cheesy” kale chip flavor without dairy.
Ranch: Combine 1 tablespoon nutritional yeast, ½ teaspoon garlic powder, ½ teaspoon onion powder, ¼ teaspoon dried dill, and ¼ teaspoon dried parsley. The herbal notes complement kale’s natural flavor.
Spicy Sriracha: Mix 1 teaspoon sriracha powder (or 1 tablespoon liquid sriracha—reduce oil slightly), ½ teaspoon garlic powder, and ¼ teaspoon cayenne. For liquid hot sauce, extend drying time by 1 hour.
Salt & Vinegar: Use 1 tablespoon apple cider vinegar plus 1 teaspoon salt. The vinegar tang mimics the classic potato chip flavor.
Everything Bagel: Sprinkle with everything bagel seasoning blend before drying. The sesame, poppy, and garlic create savory crunch.
When using liquid seasonings like hot sauce, soy sauce, or liquid aminos, reduce the oil by half to prevent soggy chips. The liquid needs to evaporate completely for crispiness, which adds 1-2 hours to drying time. Powdered seasonings work best for consistent results.
Keeping Them Crispy
Nothing’s sadder than crispy kale chips turning soggy overnight. Proper storage maintains crunch for up to two weeks.
Cool Completely: Warm chips placed in containers create condensation. Let chips cool to room temperature on the dehydrator trays for at least 10 minutes before handling.
Container Choice: Store in airtight glass jars or containers with tight-fitting lids. Plastic bags allow air exchange that leads to softening. Mason jars work perfectly and let you see when supplies run low.
The Paper Towel Trick: Place a paper towel in the bottom of the storage container to absorb any residual moisture. Replace the towel after 3-4 days if storing long-term.
Room Temperature Only: Never refrigerate kale chips—the moisture in refrigerated air makes them soggy. Store in a cool, dark pantry away from heat sources.
Check for Moisture: If you notice chips losing crunch after a few days, they weren’t fully dried. Return them to the dehydrator for 30-60 minutes at 125°F to re-crisp.
| Storage Method | Duration | Result |
|---|---|---|
| Airtight jar + room temp | 1-2 weeks | Crispy |
| Plastic bag | 2-3 days | Soggy |
| Refrigerator | 1 day | Soggy |
| Freezer | 1 month | Soft when thawed |
Conclusion
Making kale chips in a dehydrator transforms a $7 snack into a affordable, healthy treat you can enjoy by the bowlful. The key is thorough drying—completely moisture-free leaves become crispy chips that satisfy crunchy cravings without the guilt of fried snacks.
Experiment with seasonings to find your favorites, but always start with completely dry kale and don’t rush the dehydration process. At 125°F, most batches finish in 4-6 hours, though high humidity can extend this to 8 hours. The wait is worth it for chips that stay crispy for weeks rather than hours.
