Why Make Pesto Sauce With Walnuts

You can make pesto sauce with walnuts for a few really good reasons, and once you try it, you might never go back.
 
Here’s why walnuts deserve a spot in your pesto.
 

1. Walnuts Are Way Cheaper Than Pine Nuts

Pine nuts can cost an arm and a leg, especially if you’re buying them in small bags at the grocery store.
 
Walnuts, on the other hand, are affordable and easy to find pretty much anywhere.
 
When you make pesto sauce with walnuts, you get that same rich, creamy texture without the sticker shock.
 

2. They Bring a Wonderful Earthy Flavor

Walnuts have a slightly bitter, earthy flavor that pairs beautifully with fresh basil, garlic, and parmesan.
 
It’s a little different from pine nuts, but in a good way.
 
The walnuts add depth and a subtle toastiness that makes the pesto feel a bit more rustic and hearty.
 

3. Perfect for Allergies or Dietary Needs

If you’re allergic to pine nuts or just can’t find them, walnuts are a fantastic substitute.
 
You can also make pesto sauce with walnuts and leave out the cheese to keep it dairy-free, or use nutritional yeast for a vegan version.
 
It’s a flexible recipe that works for lots of different diets.
 

How to Make Pesto Sauce With Walnuts: Step by Step

Making pesto sauce with walnuts is quick and simple.
 
You’ll need a food processor or blender, and about 10 minutes of your time.
 
Here’s the basic method.
 

1. Gather Your Ingredients

To make pesto sauce with walnuts, you’ll need fresh basil leaves, toasted walnuts, garlic cloves, parmesan cheese, olive oil, salt, and a squeeze of lemon juice.
 
The lemon isn’t traditional in every recipe, but it helps keep the basil bright green and adds a little zing.
 
Use about 2 cups of packed basil, 1/2 cup of walnuts, 2 to 3 garlic cloves, 1/2 cup of grated parmesan, and 1/2 cup of olive oil to start.
 

2. Toast the Walnuts

Toasting the walnuts is a step you don’t want to skip when you make pesto sauce with walnuts.
 
Spread them on a baking sheet and pop them in a 350°F oven for about 5 to 7 minutes, or until they smell nutty and fragrant.
 
Let them cool completely before tossing them in the food processor.
 
This step deepens the flavor and removes some of the raw bitterness.
 

3. Blend the Basil, Walnuts, and Garlic

Pulse the basil, toasted walnuts, and garlic in your food processor until they’re finely chopped.
 
You want a coarse crumb texture, not a puree yet.
 
Scrape down the sides as needed so everything blends evenly.
 

4. Add the Cheese and Olive Oil

Next, add your parmesan cheese and pulse a few times.
 
Then, with the processor running, slowly drizzle in the olive oil until the pesto comes together into a loose, spoonable sauce.
 
If you want a thinner pesto sauce with walnuts, just add a little more olive oil or a splash of warm water.
 

5. Season and Taste

Finish by adding salt, a squeeze of fresh lemon juice, and maybe a pinch of black pepper.
 
Taste it and adjust as you go.
 
This is the fun part because you get to decide how garlicky, cheesy, or lemony you want your pesto sauce with walnuts to be.
 

Tips for the Best Walnut Pesto

Want to make pesto sauce with walnuts that tastes like it came from a fancy Italian restaurant?
 
Here are a few tips to keep in mind.
 

1. Use Fresh, High-Quality Basil

The basil is the star of the show, so use the freshest leaves you can find.
 
Avoid wilted or dark leaves because they’ll make your pesto sauce with walnuts taste bitter.
 
If you grow your own basil, even better.
 

2. Don’t Over-Blend

When you make pesto sauce with walnuts, stop blending as soon as everything comes together.
 
Over-processing can turn the basil dark and make the texture gummy.
 
A little texture is a good thing.
 

3. Adjust the Consistency

Some people like a thick pesto for spreading on sandwiches, while others prefer a looser sauce for tossing with pasta.
 
You can make pesto sauce with walnuts as thick or as thin as you like by playing with the olive oil amount.
 

4. Store It Right

Store your pesto sauce with walnuts in a jar with a tight lid.
 
Pour a thin layer of olive oil on top to keep it from browning, and it’ll last about a week in the fridge.
 
You can also freeze it in ice cube trays for easy portions later.
