Check out the step by step story on how to make spinach walnut pesto.
Step 1: Add basil leaves (no stems), lemon juice, olive oil to the food processor and blend about 30 seconds to break down leaves.
Step 2: Add the walnuts, 1 tbsp. water, garlic powder (or fresh garlic) and salt. Blend well, about 30 seconds.
Step 3: Add spinach (in batches) and blend well, about 1-2 minutes total. Scrape down edges of food processor if needed.
Step 4: Add additional water to thin out pesto if needed.
Top tips:
You need a food processor to make this spinach walnut pesto. We add a ton of spinach to this pesto, so you are going to want to make sure you have a powerful food processor to break it down so it’s not noticeable in the final recipe!
To make this pesto, it will be necessary to blend the ingredients in batches to ensure that everything gets finely chopped and well incorporated. If you blend everything together at once it can be hard to get the right texture.
- First blend together the basil with the lemon juice and olive oil and spices/salt.
- Next, add the walnuts and blend well.
- At the very end, you will add the spinach leaves and water.
Note: Don’t be afraid to add a little water to the mix. This helps create the final texture you want! How much water you add will depend on if you want really thick pesto (for dipping or adding to pasta that is still a little watery), or thinner pesto for spreading on sandwiches, wraps, pouring over veggies.
Tips on buying basil for pesto:
Buying basil at the store can be tough. It’s important to take a minute and inspect the carton. Once basil starts to go bad in the container (you will notice some black leaves), it will quickly take over the entire container, leaving you with $3 worth of trash once you get home.
Don’t store your basil in the fridge. Basil is best left at room temperatures. It’s important when you are packing your grocery bag not to put the basil on top of anything frozen as this will start to ruin the basil leaves.
Basil is very temperamental. We keep our house at around 64-65 in the winter and in the 70’s in the summer. Basil almost never lasts more than 2 days in our house before it starts to go black and slimy. This is why I would encourage you to use the basil you buy from the store within 2 days of purchase just to be safe!
If you need basil to last longer, my grocery store almost always has living basil – which is basil that is in its own little planter. This is a great option if you need it to stay alive for a few days!
What to serve with pesto:
- Zucchini noodles or pasta
- Roasted veggies
- Air fryer brussel sprouts (for dipping or poured over top)
- On top of air fryer salmon
- On shredded chicken
- Stirred into minestrone soup
- Poured over 5 minute blistered tomatoes
- Poured over cannenili bean salad
- Oven poached eggs
Storage:
Fridge: Once the pesto is made, it lasts about a week in the fridge. However, you may notice that after day 4-5 that the color starts to become less vibrant.
Freezer: Freezing leftover pesto is a great way to preserve it for months.
I recommend that you freeze the pesto in silicone ice cubes to make it easy to portion out. However, you may notice that the texture is not exactly the same when defrosted. This is best if you are using the pesto to flavor soups or mixing into a dish.
Frozen pesto will last about 2 months in the freezer. To defrost, simply store in the fridge or allow to defrost at room temperature.
Substitutions:
- Spinach: you can also use arugula or kale in place of the spinach. However these greens are typically more bitter than spinach so you may need more lemon juice or salt to offset the bitterness of these greens.
- Lemon juice: If you don’t have lemon juice on hand, you can also try this with about 2-3 tablespoons of white wine vinegar. The flavor will not be exact but it will be close!
- Basil: basil is what really brings the vibrant, zesty flavor to the pesto. However you could take this in a different direction by using Italian parsley or omitting the basil completely.
- Walnuts: If you don’t have walnuts on hand, you can also use:
- Almonds,
- Cashews
- Hazelnuts
- Hemp hearts
- Pumpkin seeds or
- Sunflower seeds
- Garlic powder: I use garlic powder because I find that raw garlic can sometimes be a bit overwhelming to pesto, but some people love that kick from raw garlic. If you would rather use raw garlic, you will need about 2 cloves garlic, finely chopped.
- If you cannot have garlic, I would recommend that you use roasted garlic olive oil in place of the olive oil to give it some garlic flavor without the garlic.

I’ll have to try this recipe sometime. My favorite is with the traditional basil. Thanks for sharing at the Inspiration Spotlight party! Pinned, tweeted & scheduled on my FB page. Hope to see you again soon!
You really can’t go wrong with traditional basil!
I love pesto and I have tried several different ways of making it. My favorite way is with spinach, but I think it would taste pretty awesome with kale as well.
Oh I do love spinach because it lets the basil shine through!
Oh my gosh, I SO need to make some pesto- my basil plant is going NUTS right now!! And I love the idea of adding spinach to it!! Hurray for bringing awesome posts to Snickerdoodle Sunday- so glad you linked up this weekend!

I put pesto on pretty much everything! It’s so good. I love adding different greens but the basil is a necessity. I never thought to add hemp hearts though! They’re a new favorite around these parts.
Ok you know I am all over this! What a great healthy way to make pesto I can’t wait to try this. As you know, traditional pesto is so caloric! Excited about this!
Deborah, yes it really is! I’m glad you are excited. Spinach is always the answer lol!! Great pumpkin recipe yesterday by the way!
I love hemp and I think sneaking it into pesto is a brilliant idea! Looks delicious! Pinning this one to try soon!
Yum, I love pesto! I’ve done pesto with arugula, but never with spinach.. so I’ll need to give this a try!
Perfect vegan pesto!
Thanks so much Rebecca!
I love that you replaced the parmesan with hemp hearts. They really do have such a nutty flavor. Sometimes, I sub them out for the cheese I normally put on my salads.
Stacie, we think alike, I love it! Sometimes you just gotta have cheese though :)
I’m planning on making zucchini noodles for dinner and I was just thinking about how good it would be with pesto!
Oh this would be so yummy on zucchini noodles!! But I’m pretty fond of pesto :)
If I could swim in a tub of pesto, I would, I love it so much! Hm..I wonder if these would be good on your cracker recipe… ;) thanks, Sam! Looks so yummy.
Jess the mental image of this made me laugh out loud!! Love it :) I bet it would be so good on the crackers. :) Thanks for stopping by friend!
All the basil. I wish I had more access to fresh basil. I typically have to “borrow” some from neighbors in the summer. And I have spinach every day, so there you go. I have to make my own pestos so that i can adjust the oil content.
Also, I need to find the blade for my little food processor. It is totally wrecking my cooking dreams not being able to find it!
Suzy I didn’t mention how many times I have to buy a new basil plant lol. I usually keep 3-4 at a time and normally have slim pickings. But when I get lucky, it’s fantastic! Good luck finding your food processor blade! I can’t wait to see what you whip up once you do!
Oh basil has to be my favorite herb! I used to have a small tree at home and use the leaves for cooking. The aroma was delicious! Adding spinach and kale is such a great idea! I LOVE it on everything cheese-y ;)
