Why You’ll Love It
It tastes amazing. Zucchini has a relatively neutral flavor, so it blends in seamlessly with the fresh basil, lemon juice, and garlic. It has a bright, refreshing taste that goes perfectly with your favorite pasta, pizza, sliced veggies, and more. It’s nutrient dense. Classic pesto is already a healthy sauce, made with nuts and fresh herbs, but you won’t need to use as much oil or cheese in this recipe, because the zucchini bulks it up, instead. It’s a great way to lighten things up, without missing out on any of the classic taste or texture. It’s allergy friendly. Pesto is naturally gluten-free, and adding cheese is also optional in this recipe, if you need a vegan or dairy-free sauce. It’s easy to customize. Since there’s no cooking required, you can taste this sauce as you make it, and easily make adjustments. If you don’t love garlic, use less! Or if you prefer a more tangy pesto, add extra lemon juice or a touch of lemon zest.
Ingredients You’ll Need
One large zucchini is more than you need for this recipe, but you can saute the rest of it, if you plan on serving this zucchini pesto over pasta. It’s delicious with sauteed cherry tomatoes, too! If you don’t keep walnuts on hand, you can also use pine nuts or almonds, or try sunflower seeds or pumpkin seeds if you need a nut-free option. Note: This recipe was originally posted as an oil-free vegan recipe, but I’ve also experimented with adding a touch of Parmesan cheese & extra virgin olive oil to the recipe over the past few years. Those optional additions are listed below in the printable recipe card, if you’d like to create a more authentic pesto flavor. Either way, it’s delicious!
How to Make Zucchini Pesto
- Measure the zucchini. Chop the zucchini into roughly 1/2-inch pieces, then measure out 1 heaping cup for this recipe, or about 5 ounces by weight. There’s no need to peel the zucchini for this recipe. Wondering what to do with leftover zucchini? You can freeze it for a zucchini smoothie later, or add it to stir-fry or zucchini oatmeal.
- Blend. Add the zucchini, walnuts, fresh basil leaves, lemon juice, garlic cloves, and salt to the bowl of your food processor or blender. (You’ll get the smoothest results with a blender.) Secure the lid and start blending. To help with blending, add in 3 to 4 tablespoons of water, and use a spatula to scrape down the sides of the machine, as needed. (If you’re cooking pasta to go with this sauce, reserve some of the cooking water to use here– it will thicken it up a bit more.) For an extra cheesy pesto flavor, add in a 1/4 cup of Parmesan cheese. You can also add up to 2 tablespoons of extra virgin olive oil, if you’d like the pesto to “stick” to pasta a little better.
- Enjoy! Once the pesto is blended, taste it and make any adjustments, as needed. You may want to add an extra 1/4 teaspoon of salt to help boost the flavor, or a pinch of red pepper flakes or black pepper, for a little extra spice. It’s easy to customize as you go! Serve the pesto right away over your favorite pasta or zucchini noodles, or spread it over pizza, sandwiches, and more. Leftover pesto can be stored in an airtight storage container in the fridge for up to 5 days. Or you can freeze it for up to 3 months. Pro tip: Store the pesto in an ice cube tray in the freezer, then pop the cubes out and store them in an airtight container. The ice-cube-size sauce is easier to portion and reheat later!
