It’s a perfect balance of savory garlic, fresh basil, salty Parmesan, and that distinct walnut warmth that lingers pleasantly on your palate.
2. Budget-Friendly and Accessible
If you’re on a budget, learning how to make basil pesto with walnuts is a practical move because walnuts are widely available and often cost less than pine nuts.
You can find walnuts in almost any grocery store, and they stay fresh for months when stored in an airtight container in the fridge or freezer.
This makes basil pesto with walnuts a fantastic option for home cooks who want restaurant-quality flavor without the premium price tag.
How to Make Basil Pesto With Walnuts: Step-by-Step
Now let’s get into the actual process of how to make basil pesto with walnuts, and trust me, it’s simpler than you might think.
You only need a handful of ingredients, a food processor or blender, and about ten minutes of your time to whip up a batch.
Here’s the core recipe for making basil pesto with walnuts that yields about one cup of sauce.
Ingredients You’ll Need
To make basil pesto with walnuts, gather the following fresh and pantry-stable items.
You’ll need 2 cups of fresh basil leaves, packed tightly, and make sure to remove any thick stems because they can make the pesto bitter.
You’ll also need 1/2 cup of walnuts, and toasting them lightly in a dry pan for a few minutes will really enhance their flavor.
Add 1/2 cup of grated Parmesan cheese, ideally Parmigiano-Reggiano, and 2 cloves of garlic, peeled and roughly chopped, for that sharp kick.
Finally, you’ll need 1/2 cup of extra-virgin olive oil, plus salt and freshly ground black pepper to taste, and a squeeze of lemon juice is optional but brightens things up.
1. Toast the Walnuts First
The first step in how to make basil pesto with walnuts is to toast the nuts, which is crucial for unlocking their full potential.
Place the walnuts in a dry skillet over medium heat and stir them frequently for about 3 to 5 minutes until they smell fragrant and turn slightly golden.
Be careful not to burn them because burnt walnuts will ruin your pesto with a nasty, acrid taste.
Once toasted, remove them from the pan immediately and let them cool completely before adding them to the food processor.
This little extra step makes a huge difference in the final depth of your basil pesto with walnuts.
2. Pulse the Basil and Walnuts
Add the toasted, cooled walnuts and fresh basil leaves to your food processor bowl, then pulse a few times to chop them roughly.
Scrape down the sides with a spatula to ensure everything gets incorporated evenly as you continue.
This initial pulse prevents the basil from turning into a watery paste and keeps the texture nice and rustic.
3. Add Garlic, Cheese, and Seasonings
Now add the chopped garlic, grated Parmesan, a pinch of salt, and a few cracks of black pepper to the processor.
Pulse again until the mixture is finely ground but still has a bit of texture, and you can see small flecks of basil and walnut throughout.
Taste it at this point and adjust the salt if needed, remembering that the cheese is already salty, so go easy.
4. Stream in the Olive Oil
With the processor running on low, slowly drizzle the extra-virgin olive oil through the feed tube in a steady stream.
Keep blending until you reach your desired consistency, whether you like it smooth and pourable or slightly chunky for spreading.
If the pesto seems too thick, add a tablespoon of water or more oil until it loosens up to your liking.
Once it’s ready, your basil pesto with walnuts is done, and you can scrape it into a jar or bowl.
5. Finish With Lemon and Taste
For that final flourish, stir in a teaspoon of fresh lemon juice to brighten the flavors and help preserve the vibrant green color of your pesto.
Give it one last taste and adjust with more salt, pepper, or cheese if you prefer a stronger flavor.
Your homemade basil pesto with walnuts is now ready to be slathered on bread, tossed with pasta, or dolloped over grilled chicken.
Tips for the Best Basil Pesto With Walnuts
Getting the technique right is part of how to make basil pesto with walnuts successfully, but a few pro tips can elevate your result even further.
These small details separate a good pesto from a truly unforgettable one, so pay attention to them.
1. Use Fresh, Dry Basil Leaves
Always wash your basil and dry it thoroughly before using it, because excess water will make your pesto watery and less flavorful.
Pat the leaves gently with a kitchen towel or use a salad spinner to remove as much moisture as possible.
Dry basil ensures your oil emulsifies properly, giving you a creamy, thick basil pesto with walnuts instead of a thin sauce.
2. Don’t Over-Process the Pesto
One common mistake when learning how to make basil pesto with walnuts is blending it into a completely smooth paste.
A little texture is desirable, so pulse and blend in short bursts rather than running the machine continuously for a long time.
Over-processing can also make the walnuts release too much oil and turn the pesto bitter, so stop while it still looks slightly granular.
3. Taste as You Go
Everyone’s palate is different, so tasting your basil pesto with walnuts as you build it is essential for perfecting the balance.
You might want more garlic, a touch more salt, or an extra handful of cheese, and only you can decide that.
Remember that cold ingredients taste less salty than they will at room temperature, so don’t oversalt when the pesto is just blended.
How to Store Your Basil Pesto With Walnuts
Once you know how to make basil pesto with walnuts, you’ll want to keep it fresh for as long as possible, and storage is key.
Proper storage also prevents oxidation, which is what turns your pesto brown and dulls its bright flavor.
1. Refrigerate With a Layer of Oil
Transfer your basil pesto with walnuts to a glass jar and smooth the surface with the back of a spoon.
Pour a thin layer of olive oil over the top to create a barrier that blocks air from reaching the pesto.
Seal the jar tightly and refrigerate it, where it will stay fresh for up to one week.
Every time you scoop some out, press plastic wrap directly onto the surface before sealing to maintain that protective layer.
2. Freeze for Longer Storage
Basil pesto with walnuts freezes beautifully, so you can make a big batch and save it for future meals.
Spoon the pesto into an ice cube tray, freeze it solid, and then pop the cubes into a freezer-safe bag or container.
Frozen pesto cubes can be stored for up to three months, and you can thaw them in the fridge overnight or toss them straight into hot pasta.
Just remember to omit the cheese if you plan to freeze for a long time, since Parmesan can become grainy when thawed, and add it fresh after defrosting.

To make basil pesto with walnuts, you simply toast the walnuts, pulse them with fresh basil, garlic, and Parmesan, then stream in olive oil until creamy.
