It’s Garlic Scape Season; Make Pesto Using Spinach or Kale

This is my fourth year making this pesto. What makes this year extra special is the garlic scapes came straight from my raised bed garden! I must thank my brother-in-law Mark who has been growing music garlic and generously sharing his massive haul the past three years.

Last fall, I planted his music bulbs to try my luck at growing garlic. It’s been so fun watching them sprout and grow and finally transforming them into my homemade pesto. I have to admit, the pesto came out even better this year. I’m sure I’m biased, but frankly, I don’t care!

When the scapes form a ring, it’s time to give them a haircut!

Even though I’ve been on scape duty to trim the curly tops when the garlic plants need to be trimmed, I’ve always shown up with a garden bag and kitchen shears when my BIL tells me it’s time. This year, I did my research and learned that you should pick scapes when their curlicues form a half to full circle. You need to trim them at this specific time so the garlic tops won’t get tough and woody. Most importantly, however, is trimming the them so the garlic plant’s energy reserves go toward increasing the bulb size.

If you have a CSA membership, you’re likely to get a nice bunch in your box in June to early July. Or you can stop by a local farmers’ market to score some. If you can’t easily find garlic scapes, simply follow the recipe notes on how to substitute fresh garlic cloves instead.

Enjoy All Year and Make It Your Own

I’ve been making traditional basil pesto (check out my recipe!) for decades and freeze a large batch in small containers to enjoy all year. This garlicy version expands my pesto collection as part of my summer recipe repertoire. When freezing, I prefer making a thick pesto because I will thin it out with EVOO once defrosted. Because I make a large batch, I give it away to family and friends. It also makes a nice addition to a hostess gift.

Spinach or Kale?

The past two years, I made it with spinach instead of kale. Spinach is just as good and slightly milder. Hearty kale works equally well and won’t impart a bitterness if you’re worried about that. Not only is kale considered one of healthiest and most nutritious plant foods in existence, it mellows out the flavor of the scapes and bulks up the recipe. Believe me, you won’t even taste the kale.

But if kale isn’t your thing, definitely use spinach. I found I needed to increase the volume of spinach. I’m not sure if it’s because the leaves are more delicate thus breaking down more OR if the milder green required more volume to help cut the cut some of scapes’ garlic flavor. Probably both!

When making this kind of pesto, be prepared that the scapes will steal the show. The pesto will taste fresh, green and grassy with garlic being the predominant flavor. Fresh lemon helps mellow out the garlic flavor while maintaining the bright green color of the pesto.

I tend to use my scape pesto as an add-in enhancer in marinades, red sauce, salad dressings or thinned out with EVOO and drizzled over roasted or cooked meats and veggies similar to a chimichurri sauce. It’s a perfect add-in my cherry tomato quick sauce and just omit the garlic.

Make the Recipe Your Own

As with any of my recipes, please feel free to make it your own based on your preferences. This recipe is very adaptable, so you can easily omit or change out the walnuts. Sunflower seeds, pignolis and almonds also work well. The same with the cheese, you can try nutritional yeast if not using dairy or simply omit. And if you like a milder, less garlicky flavor simply add in extra handful of spinach or kale.

Garlic Scape Pesto with Spinach or Kale and Walnuts

This pesto is easy, versatile and freezes exceptionally well. The pesto is a flavor enhancer, so add a dollop into soups, sauces, rice, salad dressings, blistered tomatoes, ratatouille, quiche and scrambled eggs. Whatever strikes your fancy!
Try it as a drizzle thinned over with EVOO over tomatoes with fresh mozzarella, grilled/roasted veggies or on cooked meats and seafood. Add some to fresh or canned crushed tomatoes to make a quick pasta sauce. It’s also perfect as a marinade for shrimp or chicken.

Ingredients

  • 1 1/2 cups garlic scapes (bulb removed) sliced into 3- to 4-inch pieces
  • 4 cups packed fresh baby spinach (or 4 large handfuls) OR 3 cups chopped kale (or 3 large handfuls)
  • 2/3 to 3/4 cup EVOO (if you like a thinner consistency, add more at the end)
  • 1/2 cup grated parmesan or Romano cheese (can swap with 1/4 cup nutritional yeast)
  • 1/2 cup walnuts (can also use sunflower seeds, pignolis or almonds)
  • Juice of a fresh lemon
  • 1 teaspoon freshly ground black pepper
  • 1 teaspoon sea salt
  • 1 teaspoon crushed pepper flakes (optional)

Instructions

Prep produce

  • Garlic scapes: Trim tough ends and remove bulb. Wash and dry in towel. Cut into 3- to 4-inch pieces.
  • Spinach: If using already-washed spinach from the grocery store you can skip this step. Otherwise, wash and trim ends (if needed) and dry using a salad spinner or towel.
  • Kale: Wash, remove tough ends and roughly chop. Dry using salad spinner or towel.

In food processor:

  • Add the garlic scapes to food processer. Pulse until roughly chopped.
  • Add in the spinach or kale and pulse until roughly chopped.
  • Add in the EVOO. Start with 2/3 cup.
  • Then add in the rest of the ingredients.
  • Pulse on chop until the mixture is finely chopped.

  • Add more EVOO if the mixture is too thick.
  • If freezing, you may choose to keep thick like a paste and thin out with EVOO after defrosting.
  • Spoon pesto into an airtight container. It will keep in the refrigerator for a week.
  • If you freeze, store in small individual containers. Or freeze in ice cube trays, and after frozen, keep into a Ziploc bag.

Notes

Pairs so well with spaghetti squash. YUM!
If you can’t find garlic scapes:
  • Use four large garlic gloves.
  • Increase greens:
    • If using spinach, increase to 5 cups.
    • If using kale, increase to 4 cups. 
  • Reduce EVOO to 1/2 cup to start. Add more as needed based on consistency. 
  • Taste and adjust flavors based on your preferences.

    Looks fabulous! I have a pine nut allergy and rarely eat pesto, so thank you for a version with walnuts!

  2. Love this concept. I am a beginner gardener and I like collecting new recipes for the fresh stuff that I grow.

  3. I am endlessly fascinated with what can be used for ingredients for a good pesto. I’ve made one with spinach before and it was divine. I’ll have to try the kale next time.

    Thank you for sharing this unique pesto recipe! I love the idea of using garlic scapes for a fresh twist. Can’t wait to try it with spinach and kale – sounds delicious and healthy!

  5. That is so cool!! I’ve never tried growing garlic. Is it possible to buy garlic scapes or is that a by product of growing garlic at home?

    1. You could find them at a farmers’ market. Or just sub out the scapes for regular garlic, as noted in the recipe, to make a spinach or kale pesto!

    1. You can also make this recipe to make a spinach or kale pesto using regular garlic (vs. scapes) by following the notes in the recipe! 🙂

    I love this idea of using spinach or kale to make pesto! It’s a great way to incorporate more greens into your diet and switch up the traditional basil pesto recipe.

    Absolutely love this! 🌱 There’s something so rewarding about using home-grown ingredients in your recipes, and it sounds like your garlic scapes have made this year’s pesto extra special. We have a garden too. We grow tomatoes, greens, and cucumbers. In addition we have fruit trees. The peaches are ripe and are so sweet! It’s nothing like fresh veggies and fruit!

    THIS. Is a great find. We all at my house have been on a kick using pesto as opposed to marinara for spaghetti. It is more flavorful and a lot less light IMO. Been finding lists of uses for it lately and stoked to give making my own a try.
