Kale chips, or kale leaves coated with olive oil and slow-baked until shatteringly crisp, are often called “kale crack” because they’re so addictive. It’s surprising but true — I have admittedly polished off an entire sheet pan by myself just standing at the stove (which is clearly why I cannot allow myself even one single potato chip). But, thankfully, kale is one of the healthiest vegetables on the planet so we can all indulge guilt-free. It has more nutritional value, higher levels of antioxidants and fewer calories than almost any other food around.

In this recipe, I’ve topped the earthy leaves with nutty Parmesan, salt and a squeeze of fresh lemon juice. It’s a delicious way to get your crispy-salty fix.

What’ll you’ll need to make kale chips with lemon and parmesan

How to make Them

Begin with a large bunch of curly kale. Remove the leaves from the thick stems and tear them into large pieces. If washing the leaves (I don’t bother unless they look gritty), be sure they are completely dry before proceeding with the recipe; moisture will cause the leaves to steam in the oven and they won’t get crispy.

Add a few tablespoons of olive oil.

Then use your hands to rub the oil evenly onto the leaves.

Arrange the leaves in a single layer on two baking sheets.

Then bake in a low oven until crispy but not browned, about 25 minutes. As you can see, the leaves shrink quite a bit.

While they’re still hot, sprinkle them with salt, freshly grated Parmesan and a squeeze of lemon juice.

Eat for your health and enjoy!

Reviews & Comments

  • Wow! Kale chips are a healthy alternative to classic chips, and Jenn’s recipe really blows kale chips out of the water! You do need to be careful of your cook time as the kale chips are very thin – too short and they will be soggy and too long and they will be burnt. We like to add cayenne pepper to ours for a little kick.

  • @onceuponachef Totally burned it. Oven setting was too high, I think. The blackened bits I tried to rescue by adding to our Alfredo with toasted pecans ands salmon. Why didn’t you put an oven temperature setting in your recipe?

    • Sorry to hear you burned these. The oven temperature is in the first paragraph under the Instructions heading. It is 300°F/150°C.

  • This is my second time making these chips and each time they have turn out perfect. They are light, crispy and flavorful. I shared this recipe with all my friends, and sent a recording so they can hear the crunch of the kale. This is by far my favorite snack.

  • I’ve made this twice now and it turned out perfect each time. It’s important to add the Parmesan right as you take them out of the oven because they cool down so fast. Thank you so much for sharing this recipe!!

  • Hello all. Made your kale chips many many times with our wonderful gas oven.
    Now in Fla and brand new appliances. Delicious back there. Horrible here.
    Is it gas or electric that makes the difference? Your thoughts?

    • Hi Tracy, sorry to hear the kale chips were disappointing! You mentioned they were horrible – – what made them so bad? Was it the texture? While it could potentially be your oven, I wonder if the level of humidity in Florida may have an impact. Here are some tips on cooking with gas versus electric ovens that you may find helpful.

  • These are so easy to make and SO delicious. My daughter and I love lemon so I add a bit more than suggested.

  • Kale chips are wonderful and I especially like this adaptation. My granddaughter and I have enjoyed massaging the kale then watching the leaves transform into chips.

  • Really loved these chips! The salt/lemon/parmesan combo really makes these tastes amazing! Definitely easy to eat a whole pan yourself in one sitting. The drying of the Kale can take longer than you want, so if you buy it without it being pre-washed, allow enough time and space to air dry or plan on drying it by hand with towels. Those curly leaves really do hold the water. The timing was spot on. Mine were nice and crisp in 25 and 27 minutes. Another delicious recipe Jenn! Thanks!

  • I bought kale at our local farm stand intending to make https://www.onceuponachef.com/2015/03/shaved-brussels-sprouts-salad-parmesan-walnuts-lemon-mustard-dressing.html but ended up using the brussels sprouts for something else. I’ve been meaning to make kale chips for a very long time. I made these tonight. They were easy to make unlike many kale recipes I’ve read. I didn’t know quite what to expect but my husband and I devoured the entire bowl in short order.

  • Totally going to jump on the Crispy Kale bandwagon. What a simple but amazing recipe. I’ve eaten more kale in the last few days than I have in my entire life. We introduced this as an snack for a dinner party and they lasted all of 5 seconds. Good thing we already had a third batch on the go (the first batch we might have accidentally eaten ourselves before any of our guests arrived). Many thanks!

  • My husband and son who–for the most part–avoid anything dark, green and/or leafy BEG me to make these. So, as any smart mom did, I taught them to make them WITH me! Now we can all make them together. But we ALL eat them together too–I have to double the batch every time!

  • We’ve just discovered kale and this recipe was an eye opener! Delicious! I used a lemon garlic seasoning for a bit more zest.

  • I was late to the kale bandwagon but now have a reserved seat. Among my favorites kale chips, and this versitle recipe is great. It is rewarding to find an intrguing recipe that not only is easy but tastes great plus is good for us. Home run.

  • Kale chips are delicious! I used the other type of kale and it worked well too.

  • This was the best, easiest, most addicting healthy snack I have ever made for my family. You cannot make enough!

  • Best recipe ever. I make this every chance I get. Perfect just as is. Wonderful, super tasty way to eat your greens!

  • Made these and loved how easy they were to make. I don’t even normally like green veggies, but these I enjoyed!

  • I also like to add pine nuts or sliced almonds to this.

  • These are so good. I love kale chips and these turned out great.

  • I love kale chips. I am a fan of the quicker, high degree roast. like 400 for 10ish minutes, I think it gives crispier kale chips.
