Kale Pesto with Pecans and Roasted Red Peppers
While I think I’m a pretty healthy eater, I’m sometimes shocked to realize I’m eating things with an ingredient list a mile long. Something’s wrong if the list is that long — especially when you’re reading words you’ve never heard of!

It’s quite easy to move away from processed spreads and condiments by making your own. It’s lovely making your own foods with whole unprocessed ingredients — you know exactly what you’re eating. So let’s skip mayonnaise and jarred pasta sauces and throw a few healthy ingredients in our food processors to come up with our own tasty creations. It’s easy and fun — and can be an incredibly flavorful treat!

Pesto is a wonderful way to add rich flavors to foods. Traditional pesto is made with basil, but why not use kale? This pesto is like eating your vitamins — it is a nutritional stand-out!

In this recipe I love roasting some of the ingredients before adding them. It enhances their flavors, and will often eliminate the need to add sugar or too much sodium.

Kale Pesto with Pecans and Roasted Red Peppers

Kale Red Pepper Pesto
Prep Time: 
Total Time: 
Makes 1-1/4 cups.
  • ½ cup Pecans, roasted
  • 1 medium Red Bell Pepper, roasted
  • ⅓ cup Extra Virgin Olive Oil
  • 2 to 4 large Garlic Cloves, roasted (here's how to roast garlic)
  • 4 cups packed green Kale Leaves (about ½ bunch)
  • Sea Salt and freshly ground Black Pepper, to taste
  1. To roast the pecans: Preheat the oven to 375 degrees F and spread the nuts evenly on a baking sheet. When the oven is preheated, put the baking sheet in and roast until the nuts look a bit oily and are very aromatic, about 4 minutes. Set aside to cool.
  2. To roast the pepper: Place it directly on top of a high flame on the stove and let it cook for a few minutes. You'll hear it crackle as the skin begins to char. Use metal kitchen tongs to turn the pepper as each side chars. It should be mostly, but not completely black. Then place the pepper in a bowl and cover it tightly with plastic wrap and let steam for about 5 minutes. Remove the plastic and let the pepper become cool enough to handle. Gently peel the skin off the pepper. Break or cut the pepper into a few pieces and then use a paring knife on the inside to remove the white membranes and seeds. Set aside.
  3. Wash, dry, and remove any tough stems from the kale.
  4. In a food processor, make the pesto by blending the kale with the roasted pecans, roasted pepper, and roasted garlic. Once it's smooth, gradually pour in the olive oil and blend until it's fully incorporated. Season to taste with sea salt and freshly ground black pepper.

I really enjoy kale, and pesto is one of my favorites, so I think this is a winning combination. Thanks for sharing!


I am printing out this pesto recipe of yours pronto – what a gift! Thanks –


I cannot get it to print but it could be our printer – someone else try?


Hi Andrew, I was browsing around on Twitter and came across a link to your blog. I love pesto and have posted a few pesto recipes on my blog as well… but it never came across to me that I can use kale instead of herbs! I love kale and I buy them every single week, so this is a must try for me! Thanks for sharing!


You can also make awesome pesto with arugula or cilantro (I use walnuts, olive oil, garlic, lemon juice, and salt and pepper to taste).


To be plainly honest, how can you not love anything Valentina makes. Can’t you just see the heart she puts into her food and her blog? 🙂

Kale pesto: Never occurred to me. Thanks for sharing your recipe, sounds like a winner.


I am just starting to can. Can I can something like this? I understand I would have to use a pressure canner and not just a boiling water bath…will it work?


Skyler, there are no tested methods for canning anything with oil. Even with pressure canning, the anoxic conditions combined with oil and garlic make it extremely risky for botulism.

Hi, I have just discovered Kale. I have fallen in love with it. I would like to make a Pesto, but am allergic to night shades and am looking for a replacement for the Bell Pepper. Do you have any recommendations?
Thank you for sharing,
