If your summer zucchini is starting to pile up, this zucchini pesto is one of my favorite ways to put it to some seriously delicious use. Made with sautéed zucchini, spinach, basil, Parmesan, and almonds, it has all the classic pesto flavor you love with a veggie-loaded twist that’s perfect for pasta, pizza, sandwiches, and more.

The pesto I make when I am overrun with summer zucchini….

Every summer I reach a point where I look at the zucchini on my counter and think, “Okay…we’ve made the muffins. We’ve grilled it. We’ve roasted it. Now what?”. And exactly how this zucchini pesto came to be. A moment of desperation, mostly. I didn’t want to waste the garden bounty, but also….I was kinda over my typical zucchini recipes. You know how they say boredom is the space in which creativity and imagination happen? Yeah, so is zucchini burnout.

But this zucchini pesto made me work for her. Lots and lots of testing. I so wanted this to be a no-cook recipe (because summer), but it just didn’t shine. Believe me…I tried, but the raw zucchini made the pesto watery and gave it a fresh, almost grassy flavor that just wasn’t what I was after. I found a quick sauté completely changed everything. It cooks off some of the zucchini’s moisture, gives it a lightly caramelized flavor, and makes the pesto the perfect texture, a little flavor oomph rich, and so absolutely worth that one extra step.

Once the pesto is made, the possibilities are endless. It stores great in the fridge for about 5 days, so you can make it and then toss it with your favorite pasta, spread it on sandwiches, spoon it over grilled chicken or salmon, or use it as the sauce on homemade pizza. My Zucchini Turkey Meatballs are especially delicious with this pesto spooned over them but its also pretty magical in my  Pesto Pasta Salad. Also, if you REALLY want to make that summer zucchini last into the fall, this recipe freezes beautifully, so go ahead and double the batch.

Let’s make it together. Just you and me…

Tips and tricks from my kitchen to your’s

  • Don’t skip the cooking. Trust me, I tried it. We tested this pesto with raw zucchini (because who wants extra steps??) and found that it was quite watery and the raw veggie flavor didn’t quite work for what we were loving. The cooking process helps to cook off some of the zucchini’s water and give it a delightful flavor…so its worth the extra step to make something thats truly tasty.
  • Make it nut-free. I know some people need that I gave this a go with sunflower seeds and it worked great too! I also bet pumpkin seeds would be a great sub for the nuts too.
  • Use toasted nuts for a deeper, richer flavor. It just depends on how fancy you are feeling. You can toast nuts in a dry skillet over medium heat, (watching them carefully) until they are golden brown. This takes just a minute or two.

Zucchini Pesto (without Pine Nuts)

Yield: 6 servings
Prep Time: 10 minutes
Cook Time: 15 minutes
Total Time: 25 minutes
Cuisine: American, Italian
Course: Condiment, sauce
If your summer zucchini is starting to pile up, this zucchini pesto is one of my favorite ways to put it to delicious use. Made with a pound (!) of sautéed zucchini, spinach, basil, Parmesan, and almonds, it has all the classic pesto flavor you love with a veggie-loaded twist that's perfect for pasta, pizza, sandwiches, and more.

Ingredients
 

  • 2 Tablespoons extra virgin olive oil, divided
  • 1 pound zucchini , (about 2 medium), ends removed, cut in half lengthwise, then thinly sliced
  • 2-3 cloves garlic, minced
  • ¾ teaspoon kosher salt, divided
  • 1 cup packed baby spinach
  • ½ cup packed basil leaves
  • ½ cup sliced almonds
  • ½ cup grated Parmesan cheese
  • 1 Tablespoon fresh lemon juice

Instructions
 

  • Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the zucchini and cook, stirring occasionally, until softened and lightly golden brown, about 5 minutes.
  • Turn the heat down to medium, then stir in the garlic and ½ teaspoon kosher salt. Cook until the garlic is lightly toasted and the zucchini is well browned, another 2 to 3 minutes.
  • Transfer the cooked zucchini the bowl of a food processor fitted with the metal blade. Allow the zucchini to cool until just warm. (You could also do this part ahead of time and allow the zucchini to cool fully before making the pesto.).
  • Once the zucchini is cool, add the spinach, basil, nuts, parmesan, lemon juice, 1 tablespoon of olive oil, and remaining ¼ teaspoon salt.
  • Blend until creamy and mostly smooth, stopping to scrape down the sides of the bowl as needed.
  • Taste and add more salt and/or lemon juice as you’d like. Use the pesto right away or store in an airtight container in the refrigerator for 4 to 5 days.

Notes

How to use the pesto:
  • Toss with your favorite cooked pasta to use as a sauce. For pasta salad, whisk a little extra olive oil into the pesto then use as the dressing.
  • The pesto can be used as a spread in a sandwich or for the sauce on the base of a pizza.
  • You can also use the pesto as a dip for raw veggies and crackers.
 
Adaptations 
  • You can make this pesto nut-free by replacing the nuts with seeds such as pumpkin seeds or sunflower seeds
  • For a dairy-free pesto, leave out the parmesan cheese and add additional salt to taste. The pesto will still be delicious without the cheese.
  • Toast the nuts for a deeper flavor. You can toast nuts in a dry skillet over medium heat, (watching them carefully) until they are golden brown.
