Crispy kale chips in air fryer
- Kale: you might substitute with Swiss chard, collard greens, or even beet greens if you don’t have kale.
- Olive oil: you could use avocado oil, coconut oil, or sunflower oil instead of olive oil.
- Paprika: smoked paprika, sweet paprika, or chili powder can be used for different flavor profiles.
- Garlic powder: onion powder or finely minced fresh garlic work if you prefer a more pungent flavor.
- Cayenne pepper: you might leave it out for mild taste, or use red pepper flakes instead.
- Kosher salt: sea salt or Himalayan pink salt make fine replacements.
Cooking tips
- Always dry your kale thoroughly after washing it; any moisture makes chips soggy.
- Remove the thick ribs (stems) before frying so that every leaf piece crisps evenly.
- Don’t overcrowd the air fryer basket; cook in batches to allow good air circulation.
- Shake or toss the basket halfway through cooking to ensure uniform browning.
- Pay attention to your air fryer’s temperature calibration: different brands run hotter or cooler, so you might need to adjust time ± 1-2 minutes.
Ingredients
- Kale leaves: 6 ounces (≈170 grams)
- Olive oil: 1½ tablespoons (≈22 ml)
- Kosher salt: ½ teaspoon (≈2.5 grams)
- Smoked paprika (or regular paprika): ½ teaspoon (≈1.5 grams)
- Garlic powder: ¼ teaspoon (≈1 gram)
- Ground black pepper: 1 pinch (≈ a small pinch, to taste)
- Cayenne pepper: 1 pinch (≈ a small pinch, or omit for mild flavor)
- 1. Preheats the air fryer to 360°F (≈180°C) following the manufacturer’s instructions before you start cooking.
- 2. Strips kale leaves off the thick ribs, then chops the leaves into bite-sized pieces. Places them in a large bowl.
- 3. Drizzles olive oil over the kale, sprinkles kosher salt, smoked paprika, garlic powder, ground black pepper, and cayenne pepper. Tosses everything until each piece is lightly coated.
- 4. Adds a single layer of the kale pieces into the air fryer basket, making sure not to crowd.
- 5. Cooks the kale for about 3 minutes, then pauses to shake the basket to redistribute leaves. After shaking, removes the pieces and spreads them out on a baking sheet or board to cool and crisp up.
- 6. Repeats cooking with remaining kale in batches until all are done, taking care each batch receives equal heat exposure.
- 7. Chef’s advice: Because air fryers vary so much, you’ll want to observe your first batch closely. When I made this for the first time with a new model, I found that reducing time by one minute prevented over-browning on the edges. Also, using smoked paprika adds a deeper, more roast-like flavor that pairs well with the natural earthiness of kale.

FAQ
How do I prevent kale chips from becoming soggy in the air fryer?
Kale chips often turn soggy if the leaves are not dried thoroughly after washing. From my own cooking experience, patting them completely dry with a clean kitchen towel or using a salad spinner is essential. Any residual water turns into steam in the air fryer, softening the leaves instead of crisping them. Cooking in small batches and avoiding overcrowding also helps the hot air circulate properly, giving consistent crunch in every batch.
Can I make these kale chips gluten-free and lactose-free?
Yes, kale chips are naturally gluten-free and lactose-free when prepared with simple seasonings and oil. This makes them an excellent snack for people with celiac disease, gluten sensitivity, or lactose intolerance. I have tested them for friends with dietary restrictions, and as long as you avoid spice blends containing wheat starch or powdered cheese with dairy, the recipe stays fully compliant with these diets. Always check the labels on spice mixes to confirm there are no hidden allergens.
How should I store leftover kale chips to keep them crispy?
After testing different storage methods, the best way to preserve kale chips is to let them cool fully and then place them in an airtight container at room temperature. If you store them while still warm, condensation will soften them. A small piece of paper towel inside the container absorbs excess moisture and helps maintain crunch for up to 2–3 days. Do not refrigerate them, as cold air adds unwanted humidity that quickly ruins the texture.
Can I freeze kale chips and reheat them later?
Freezing kale chips is not recommended because the ice crystals formed during freezing change their fragile structure, making them limp once thawed. If you need to prepare ahead, it is better to wash, dry, and cut the raw kale leaves in advance, then store them in the refrigerator for up to 3 days. That way, you can season and air fry them fresh, ensuring maximum crispiness without the loss of texture that freezing causes.
What are the most common mistakes to avoid when making kale chips in the air fryer?
From my trials in the kitchen, the most frequent mistakes are: not drying the kale properly, using too much oil, setting the air fryer temperature too high, and overcrowding the basket. Excess oil causes uneven cooking and sometimes a greasy taste, while high heat can burn the delicate leaf edges before the rest crisps up. By keeping the oil light, spacing leaves out, and monitoring time carefully, you avoid these pitfalls and achieve consistently crunchy chips.
How can I adjust the texture if my kale chips come out too bitter or too soft?
Bitterness usually comes from overcooking or using older kale leaves. Choosing fresh, tender kale and reducing cooking time by one minute can improve flavor significantly. If the chips are too soft, it generally means there was residual moisture or they weren’t cooled in a single layer after cooking. Letting them cool on a wire rack or flat baking sheet prevents trapped steam and locks in crunch. These adjustments are simple but make a major difference in taste and texture.
