Why You Should Make Basil Pesto With Walnuts

The short answer is that you can make basil pesto with walnuts and it’s a fantastic choice for so many reasons beyond just convenience.
 
Walnuts bring a buttery, slightly bitter note that pairs beautifully with the peppery fresh basil and sharp garlic, and they don’t overpower the herbs like some other nuts might.
 
Plus, walnuts are packed with omega-3 fatty acids, which means your pesto gets a little nutritional boost without sacrificing any of that creamy texture you love.
 
When you make basil pesto with walnuts, you’re also getting a more budget-friendly sauce because walnuts cost a fraction of what pine nuts do these days.
 
And since walnuts are available year-round, you can whip up this pesto any time you have a bunch of fresh basil on hand, no need to hunt down specialty ingredients.
 

1. Walnuts Give Pesto a Richer Flavor

When you make basil pesto with walnuts, the first thing you’ll notice is how the flavor deepens compared to traditional pine nut pesto.
 
Walnuts have a natural earthiness that mellows out the sharpness of raw garlic, so the final sauce tastes more rounded and savory.
 
Toasting the walnuts for just a few minutes before blending intensifies this nutty taste even more, making your pesto smell absolutely irresistible.
 
The walnuts also help balance the brightness of the basil, so you get a sauce that’s both fresh and comforting at the same time.
 

2. It’s a More Affordable Alternative

Pine nuts can be shockingly expensive, so learning how to make basil pesto with walnuts is a smart money-saving hack for home cooks.
 
A bag of walnuts gives you way more quantity for the same price as a tiny jar of pine nuts, and you can store the leftovers in the freezer for months.
 
This means you can feel good about making a big batch of pesto without worrying about breaking the bank.
 
And because walnuts are so common, you probably already have them in your pantry, which makes this recipe perfect for last-minute meal prep.
 

3. Walnuts Blend Into a Creamy, Smooth Texture

When you make basil pesto with walnuts, you get a wonderfully creamy consistency that coats pasta and spreads like a dream on crusty bread.
 
Walnuts have a higher oil content than some other nuts, which helps emulsify the pesto and creates that silky mouthfeel we all crave.
 
You don’t need to over-process it either, just a quick pulse in the food processor and you’ll have a chunky or smooth sauce depending on your preference.
 
The natural oils from the walnuts also mean you might need a little less olive oil, so your pesto stays lighter but still luscious.
 

Step-by-Step: How to Make Basil Pesto With Walnuts

Now that you’re sold on the idea, let’s get into the actual process of making basil pesto with walnuts from scratch.
 
You’ll need a handful of simple ingredients, fresh basil leaves, walnuts, garlic, Parmesan cheese, olive oil, and a pinch of salt and lemon juice.
 
The beauty of this recipe is that it comes together in about ten minutes, and you don’t need any fancy equipment beyond a food processor or blender.
 
Here’s how to make basil pesto with walnuts step by step, and I promise it’s foolproof even if you’re a total beginner in the kitchen.
 

1. Prep Your Basil and Walnuts

First, wash and thoroughly dry your fresh basil leaves because any excess water will make your pesto watery and dull in color.
 
Gently pull the leaves off the stems and discard the thick stems as they’re bitter and fibrous.
 
Next, toast your walnuts in a dry skillet over medium heat for about three to five minutes until they smell fragrant and turn light golden brown.
 
Keep a close eye on them because walnuts burn quickly, and burnt nuts will ruin the whole batch of pesto.
 
Let the walnuts cool completely before you add them to the food processor.
 

2. Combine Everything in the Food Processor

Add your cooled walnuts, fresh basil leaves, peeled garlic cloves, and grated Parmesan cheese into the bowl of your food processor.
 
Pulse the mixture a few times to chop everything down into a coarse paste before you add any liquid.
 
This step helps ensure that no big chunks of garlic or walnut remain, giving you a more uniform pesto.
 
Then, with the motor running, slowly drizzle in your extra virgin olive oil until the pesto reaches your desired consistency.
 
You can add a squeeze of fresh lemon juice and a pinch of salt at this point to brighten up all the flavors.
 

3. Adjust the Texture and Seasoning

If you’re asking how to make basil pesto with walnuts that’s not too thick, just add a tablespoon of warm water or more olive oil and pulse again.
 
Taste the pesto and adjust the salt, garlic, or lemon to your liking, and remember that Parmesan is salty so go easy on the salt at first.
 
For a vegan version, simply skip the Parmesan and add a little nutritional yeast for that cheesy, umami flavor instead.
 
You can also swap some of the basil for baby spinach if you want a milder taste, but keep that basil forward so it still tastes like classic pesto.
 

4. Store or Use Immediately

Your basil pesto with walnuts is ready to use right away, toss it with hot pasta, spread it on sandwiches, or spoon it over grilled chicken.
 
For storage, transfer the pesto to a glass jar and cover the top with a thin layer of olive oil to prevent browning.
 
It will keep in the fridge for about a week, or you can freeze it in ice cube trays for up to three months.
 
Just thaw the cubes in the fridge overnight and you’ll have fresh-tasting pesto whenever you need it.
 

Tips for the Best Basil Pesto With Walnuts

To really nail how to make basil pesto with walnuts, there are a few extra tricks that separate good pesto from great pesto.
 
First, always toast your walnuts gently, it’s a tiny step that makes a huge difference in flavor.
 
Second, use the best quality extra virgin olive oil you can find because it’s the backbone of the sauce and you’ll taste it.
 
Third, don’t over-blend the pesto, you want a little texture left to it rather than a completely pureed paste.
 
Finally, add your Parmesan at the end and pulse just until combined, over-processing can make the cheese turn gritty.
