Countless other food bloggers have asked “Why did it take me so long to make kale chips?” so I’ll spare you that and just say that now that I’ve finally made roasted kale chips myself, I see what the fuss is about. Not only are they full of nutritious goodness, but these Roasted Kale Chips with Sea Salt and Vinegar are delicious. If you don’t believe roasted crispy kale leaves can be that special, I challenge you to try them and see what you think.

When I finally decided I had to try making kale chips, I found there were endless variations on the recipe, with different cooking times and slightly different methods. I can be a perfectionist, so I texted 6 slightly different versions before I came up with the recipe I liked best, where the kale chips are roasted for a longer time at a fairly low temperature.

I wanted to make salt and vinegar chips, and I found I liked the kale best when the salt was added after roasting. I didn’t think my final kale chips were my most photogenic batch, and I don’t know if adding the vinegar made the kale chips turn more brown, but I didn’t care how photogenic they were because I loved the taste. Anyway, there is certainly no one perfect way to make kale chips, but this is how I did it.

How to Make Roasted Kale Chips with Sea Salt and Vinegar:

(Scroll down for complete recipe with nutritional information.)

  1. Start with a lovely bunch of curly kale. This was about six ounces, and since I was roasting it in my toaster oven (before the new stove arrived) that was just the right amount to fit on a small cookie sheet.
  2. Cut away the inner ribs and discard, and then tear the kale leaves into same-size pieces. (I made my pieces about the size of a small potato chip.)
  3. Here’s how many pieces I got from the 6 oz. bunch of kale in the top photo.
  4. I washed my kale in a salad spinner, and then spun it dry over and over, until the leaves were dry. If you don’t have a salad spinner, I’d use paper towels to dry the leaves.
  5. I used olive oil, Spanish sherry vinegar, and sea salt to flavor the chips, but I think any type of salt and vinegar that you like the flavor of would be fine.
  6. I wanted to “massage” the kale leaves with olive oil to be sure they were well-coated, so I put the chips into a Ziploc bag, added half the olive oil, squished it around, added the rest of the oil, and then massaged some more.
  7. Then I sprinkled in the vinegar, closed the bag, and shook it until the drops of vinegar were well-distributed on the kale pieces.
  8. In all the directions, probably the most important thing is to arrange the kale pieces in a single layer on the pan so they aren’t crowded when they cook. Here are my kale pieces when they started out in the 300F/150C oven.
  9. Here are the chips after they roasted for 10 minutes.
  10. This next photo is how they looked after 20 minutes.
  11. They’re a little more crispy after 30 minutes.
  12. I let them cook five minutes more for a total of 35 minutes roasting time. Sprinkle with sea salt and eat immediately!

I experimented with six version of Kale Chips, but these Roasted Kale Chips with Sea Salt and Vinegar were the ones I thought were really a treat!

Ingredients

  • one bunch of kale leaves, about 6 oz.
  • 1 T extra-virgin olive oil
  • 1 T vinegar (see notes)
  • sea salt to taste

Instructions

  1. Preheat oven to 300F/150C.
  2. Cut away inner ribs from each kale leaf and discard, then tear the kale leaves into same-size pieces. (I made my pieces about the size of a small potato chip.)
  3. Wash torn kale pieces and spin dry in a salad spinner or dry with paper towels until they're very dry.
  4. Put kale pieces into a large Ziploc bag (or use a bowl if you don't mind getting your hands oily.)
  5. Add half of the 1 T of olive oil, seal bag, and squeeze the bag so the oil gets distributed evenly on the kale pieces.
  6. Add the other half tablespoon of oil and squeeze the bag more, until all kale pieces are evenly coated with oil and slightly "massaged."
  7. Open the Ziploc bag and sprinkle the 1 T sherry vinegar over the kale leaves, then seal bag and shake to spread the vinegar out over all the leaves.
  8. Arrange kale leaves in a single layer on a baking sheet, then roast until they are mostly crisp, about 35 minutes.
  9. I checked every 10 minutes or so and turned some pieces over.
  10. I also found I didn't mind if there were a few softer parts on some of the kale leaves, I liked the combination of crisp and softer parts.
  11. When chips are done to your liking, sprinkle with a generous amount of sea salt and eat immediately.

Notes

I used Spanish sherry vinegar, but any vinegar you like the flavor of will work

  1. I think rice vinegar is much milder in flavor than the one I used.

  2. I love kale chips. This is my first try at a real "flavor". I tried it with garlic infused rice wine vinegar and you couldn't taste the vinegar 🙁 I'm not sure if that was because of my choice in vinegars.

  3. I've made kale chips before! I've never tried it with vinegar before. I have a bag of kale in the fridge that I'm tempted to try this right now!

    That's my simple kale chip recipe:
