Don't mess with pine nuts because they are hella expensive and sometimes cause terrifying "pine nut mouth"? Well, my dearest mommy, this walnut pesto might just have a wee bit more swagger than classic basil pesto anyway. In about 5 minutes, toasted walnuts, herbs, lemon, and olive oil whirl together into a sauce that tastes like an Italian grandmother whispered ancient flavor secrets into your food processor.
Recipe tips tailored to what matters most to you:
Zero wheat in this walnut pesto, confirmed right on the recipe card, so it's already gluten-free as is.
This walnut pesto is already a 6-minute job start to finish, so there's really no step left here to fast-track.
Grab the cheaper bag of walnut pieces instead of whole walnuts, they toast and blend just as well.
Swap in a bit more basil and parsley for some of the walnuts to lighten up the pesto without losing that herby punch.
Dried oregano works fine if fresh isn't in your spice rack, just skip that swap for the basil and parsley since dried versions turn into flavorless confetti.
Lightly toasting the walnuts brings out their natural oils and aroma. This step really does deepen the flavor noticeably.
Grab the fresh basil leaves and discard the thicker stems so the sauce stays smooth and herby instead of tasting like you blended a tiny swamp.
Use a microplane to grab just the thin outer yellow peel so you get the fragrant oils and none of the bitter white pith.
Oodles more tips, step-by-step recipe photos, info on weird ingredients, and FAQs are all still here. I just tucked 'em out of the way so you can start cooking sooner.
Listen, walnut pesto is not some weird modern internet experiment invented by a blogger running on 2 hours of sleep and leftover Yerba Maté (a.k.a. me), and it's not an AI fever dream that ChatGPT burped up either.
Italians have been making pesto with walnuts for ages, mostly because pine nuts can cost a small fortune, and also because walnuts bring a wonderfully rich, buttery, slightly sweet thing to the party that works ridiculously well with basil, herbs, olive oil, and lemon.
Now once you've got a bowl of this pesto sitting on your counter, it's impossible to not think about things you want to slather this green stuff on. Toss it into my vegan pesto pasta, drizzle it over vegan carbonara, or drag a piece of vegan garlic bread through it and watch a full loaf disappear and nobody knows how that happened.
Cool, cool, I genuinely love that for you. Now let's make the darn pesto already.
Oh yes! Very very yummy. Thank you Chef Adam

🌱 Walnut Pesto Ingredients
Walnuts
Whole walnuts or walnut pieces both work great in this recipe, just toast them for a couple of minutes so the flavor goes from "hi" to "Hello! ma honey, Hello! ma baby, Hello! ma ragtime gal."
Basil Leaves
Grab the fresh basil leaves and discard the thicker stems so the sauce stays smooth and herby instead of tasting like you blended a tiny swamp.
Lemon Zest
Use a microplane to grab just the thin outer yellow peel so you get the fragrant oils and none of the bitter white pith.
Extra Virgin Olive Oil
Grab a legit first cold-pressed extra-virgin olive oil because this is one of those recipes where kick-@$$ olive oil makes a noticeable difference. If the oil is boring, the homemade pesto will be kinda boring too, and you didn't show up on my blog longing for boring.
*See the recipe card at the bottom of the page for exact quantities, nutritional info, and detailed cooking directions.
🤯 Variations
Spinach Pesto
Something even greener and fresher? Spinach pesto blends basil and spinach for a tasty sauce that's a bit cheaper to make and is great for you too.
Pistachio Pesto
Pistachio pesto has a tiny bit of heat from arugula and crushed red pepper flakes. It's one of my personal fave ways to do the whole pesto thingy.
Sun-Dried Tomato Pesto
Sun-dried tomato pesto packs concentrated tomato goodness into a thick, spreadable sauce with a hint of red wine vinegar and garlic. It's pretty great, really.

📖How to make walnut pesto
Pasta sits up a little straighter when there's a bangin' homemade sauce involved. Follow the step-by-step instructions below and you'll have walnut pesto on the table… assuming you don't chug half of it straight from the blender. But if you're in a hurry, the printable recipe card is waiting further down the page.
Step One
Walnutty Professor:
Place the walnuts in a dry skillet over medium heat. Stir and flip them frequently for 2-3 minutes until they become fragrant and lightly browned. Transfer them to a plate and allow them to cool completely.
Step Two
More Herb Than a Cypress Hill Concert:
Add the cooled walnuts to a food processor along with the basil, parsley, oregano, garlic, lemon zest, lemon juice, black pepper, and salt. Pulse several times until the mixture is finely chopped and begins forming a coarse paste, scraping down the sides of the bowl as needed so it processes evenly.
If your heart whispers "add vegan parmesan cheese," you should probably listen to it and add a few grated tablespoons.
Step Three
The Oil Tenenbaums:
With the machine running, slowly pour in the olive oil in a steady stream so the mixture emulsifies and becomes smooth.
Step Four
Don't Abolish This Kind of Ice:
Add the crushed ice and process again until all the ice breaks down and the sauce loosens to a spoonable consistency. Taste and adjust the seasoning if needed.
🤷♀️ Recipe FAQs
Lightly toasting the walnuts brings out their natural oils and aroma. This step really does deepen the flavor noticeably and helps the fresh pesto taste fuller and more balanced.
Yes. Yes, yes, yes!
A blender works great, or you can channel your inner old-school Italian chef self and pound the walnuts and fresh garlic in a mortar and pestle before mixing in the herbs and olive oil.
Use fresh herbs whenever possible because pesto lives and dies by that bright green flavor. Dried oregano is fine if needed, but dried basil and parsley are basically decorative green confetti and will make a truly sad pesto.
🧊 Refrigerating
Transfer the leftover walnut pesto sauce to a sealed glass container and refrigerate it for up to 5 days. A thin layer of olive oil on the surface helps reduce air exposure and keeps the color bright.
❄️ Freezing
Walnut pesto freezes well for longer storage. Spoon it into a small airtight container, then store the frozen portions for up to 3 months.
