Large Batch Basil Pesto
This post may contain affiliate links. Please read my disclosure policy.

I’ve been trying to get this post out for weeks and almost, in fact, didn’t publish it because I feared at this point in the summer it might be irrelevant, but a trip to the Schenectady Greenmarket this past Sunday quelled my worries. Basil—in large bunches—is still readily available and affordable. And perhaps your backyard basil bushes are flourishing, too? (Mine are dead.)
Three weeks in a row (several weeks ago now), an enormous bunch (or two!) of basil arrived in our CSA. Initially I used the basil as needed, but the bounty eventually caught up with me, so I made a very large batch of basil pesto, and for the first time ever, I froze it in individual blocks using my ice cube tray. This is probably something you all have been doing for years, and I absolutely should have been, too, but alas I have not. Note: Historically my freezer is the place where things go to die.
There is a recipe below for a straight-up, large-batch basil pesto with notes for making a small batch as well as for adapting the recipe to whatever herbs and nuts you have on hand. I hope it might be handy should you find yourself with an overload of herbs.
Hope your summer is going well, Friends. I feel a bit in the weeds in regard to the blog, but I suppose this is a good thing? I’ve been spending my days with the kids at the town pool or park or with my in-laws or parents, and for the first time, I’ve actually been really enjoying* it. Hope you all are so well.
*I did, however, just sign the kids up for a week of full-day soccer camp because this “fun mom” is running out of steam.
Reminder: Store basil out of the fridge in a tall glass with a little bit of water. Here’s a how-to-make-pesto play-by-play:
Remove tough stems; tender ones are OK:

Gather your ingredients. I have not been using nuts, but absolutely use nuts if you wish.
If you are making a large batch, you’ll likely have to process the pesto in batches.
Add herbs, cheese, garlic, nuts, etc. into food processor:
Purée until everything is combined. Taste, and adjust seasoning as desired with more salt, lemon, oil, etc:

I’ve been using the pesto on sandwiches. Love this one: roasted red peppers, fresh mozzarella, and greens on ciabatta:
Also great tossed with grilled vegetables:
Store pesto in fridge or freezer. Freeze pesto in ice cube trays; then transfer the frozen cubes to a ziplock bag and return to the freezer. Look: I found purpose for my canelé mold I have yet to use—score!
Large or Small Batch Basil Pesto
- Total Time: 20 minutes
- Yield: 4.75 cups 1x
Description
Pesto can be made with many a herb (parsley, chives, tarragon, cilantro) as well as many a vegetable (kale), cheese (pecorino), and/or nut (walnuts, almonds, hazelnuts). Because our CSA had gifted us three enormous bundles in two weeks, I made a straight-up basil pesto, omitting the nuts mostly because they’re so darn expensive. If you like the texture and flavor offered by nuts, you can definitely add them here. Quantities are listed in ingredient list.
Pesto freezes beautifully. Freezing in ice cube trays or something similar is handy, because it allows you to remove small portions as needed.
Re kosher salt: I note the brand I use, Diamond Crystal, because saltiness varies among brands. If you use Morton’s kosher salt, for example, you should cut the amount of salt back because Morton’s is saltier than Diamond Crystal.
To make a small batch of pesto, use these quantities:
- 4 cups (85 g) loosely packed basil
- 2 to 4 cloves garlic, peeled
- 1 to 2 tablespoons fresh lemon juice
- 1 teaspoon kosher salt (Diamond Crystal brand, see notes)
- 1/2 cup (57 g) grated Parmigiano Reggiano
- 1/4 cup toasted pine nuts, almonds, or walnuts (optional)
- 1/2 cup extra-virgin olive oil
Ingredients
- 16 cups (320 g) basil
- 1 head garlic, peeled
- 1/2 cup fresh lemon juice
- 3 to 3.5 teaspoons kosher salt (Diamond Crystal brand, see notes)
- 2 cups (215 g) grated Parmigiano Reggiano
- 1 cup toasted pine nuts, almonds, or walnuts (optional)
- 2 cups extra-virgin olive oil
Instructions
Combine basil, garlic, lemon, 3 teaspoons of the salt, and the cheese in a food processor. Pulse to combine—you may have to pulse in batches. Add the oil and purée to combine. Taste. Adjust with more salt, lemon or oil to taste. Store in fridge or transfer to ice cube trays and freeze; then transfer to a ziplock bag and store in freezer.

And if you’re making a REALLY large batch, line a 13×9” baking dish with plastic wrap, pour in the pesto, cover with more wrap and freeze. Then pop the block of frozen pesto on a large cutting board and cut into ice-cube-sized squares. Wrap each and keep in a zipper bag in the freezer. Best to pre-cut small pieces of plastic wrap, so you can wrap the cubes of pesto before they start melting.
Genius tip Maureen
I also freeze my pesto but in jars with the lid off till frozen. I do use nuts but not pine nuts anymore, usually walnuts. They are cheaper and I like the health benefits and taste of them. Please remember some of us readers are from the other side of the world so yes my basil is growing well when it isn’t over there.
We just made this with our fresh basil. Easy and wonderful.
So happy to hear this, Carol!
I have so much basil in my garden and would love to make a big batch of pesto. I find my pesto always goes brown though when I make in advance so am reluctant to make a large quantity. I have not used lemon juice before – is this the secret? Thank you!
Mine always goes brown after a few days in the fridge, too. But what’s great about making a big batch is that you can freeze it! I froze it in ice cube trays, then transferred the cubes to a plastic bag. Now, when I want a cube, I just grab one, let it that or toss it into a pan to let it melt. It’s so handy!
Blanch the basil leaves in boiling water for 20 seconds. Drain the leaves in a colander and then put them in ice water.
Squeeze the water out and make your pesto.
This method prevents the pesto from turning brown after freezing it.
Hi Alexandra,
Just a friendly note – parmesan isn’t vegetarian, so that tag should probs be removed. x
Thanks! Will make a note!
I believe vegetarian is usually no meat, and can include milk products, but vegan does not include any animal product at all. This recipe looks great, and I will make it this week!
Unless it is specifically labeled as vegetarian, most cheese, including Parmesan, is made with rennet, which is the lining of a calf’s or lamb’s stomach, and for that reason is not considered vegetarian.
Most Parmesan made in the US IS made with vegetarian rennet and is perfectly suitable to use.
Can you freeze this pesto with the cheese in it or should you leave it out? I keep reading that pesto doesn’t freeze well with cheese in it.
I freeze it with the cheese, and it has been fine for me!
I cut the small recipe in 1/4ths and made one just enough for 4 chicken thighs-was easy and delicious!!!
Amazing! Love this, Harriet 🎉🎉🎉🎉🎉
I love this recipe, but the salt is way too much.
Made this today – delish! Thank you!
Great to hear, Mackenzie!
We’ve been freezing basil oil cubes (just basil, olive oil and garlic) for years. I like the flexibility of adding my choice of nuts and cheese when I pull a cube or two out of the freezer. They seem to last longer in the freezer this way.
I’m excited to have your CSA newsletter. Thanks!
So interesting, Leslie! Love this idea. I’ll give it a try… I’ll have mounds of basil on hand to experiment with 🙂 🙂 🙂 Thanks for signing up for the farm share newsletter!
Just made this and it was amazing! Beats my previous pesto recipe by far!!!! I was fortunate to have pine nuts, so I used those. So delicious! Thanks for the great recipe!!!
Great to hear, Kris! Nothing better than basil pesto this time of year. Thanks so much for writing 🙂 🙂 🙂
Just made this tonight thanks to a thriving basil plant in the garden this year. Your recipes are always my go-tos! I go a little heavier on the lemon juice, a bit lighter on the salt but there’s room for that in this recipe – it’s to taste! Paired it with some roasted garden cherry tomatoes, mini mozzarella and pasta with a splash of pasta water and it was to die for. Jarred the rest up to freeze and give to coworkers. Thanks!
So nice to read all of this Nancy! What lucky coworkers you have 🙂 🙂 🙂
I love pesto. This large recipe is one of the best I have seen. I am looking forward to making it this afternoon.
Hope you love it Valerie!
Hi Ali. Before I start on my third large batch of pesto this afternoon (oh how my neighbors love me) I am reminded to mention that picking all that basil is time consuming and annoying. I use kitchen shears — snip, snip, snip and the job is done in a fraction of the time. Easier on my thumb, too.
Brilliant! Thanks Pat 🙂 🙂 🙂 I have a batch of ratatouille cooking away as I type. Tomorrow is my pesto day. Love this time of year 🙂
Don’t freeze in ice cube trays. Difficult to remove. Just put two tablespoons into snack bagels. Cut the olive oil. One cup is too much. Really be careful with salt. Otherwise, great!
Great recipe, thank you!
I use a lot of your recipes and the pesto is an perennial favorite. I just have a question about kosher salt. I buy Hannaford’s generic version. Would you equate that to the Diamond or Morton versions? Is the concentration based on the size of the flake? Funny thing is my son, who is also a chef, couldn’t answer this!
Hi! To be safe, I would equate it with Morton, and use half as much by volume as Diamond Crystal. This way, you can adjust with more salt if necessary. I honestly don’t know either about the concentration in relation to the size of the flake.
Great to hear you love this one 🙂
I have been making pesto for years. This recipe is the best I’ve ever tried! We love it and now it’s my go-to recipe. Freezes beautifully, too. Thank you!
Great to hear! Thanks for writing 🙂
Just made the large batch of this with the final big harvest of my basil. I did blanche the leaves for 20 seconds so it doesn’t lose its beautiful color. I did it in 4 batches due to the size of my food processor and also used walnuts. It turned out DELICIOUS! Thanks Ali!
Great to hear, Mert! And great tip on blanching the basil… I’ll try that!
I just wanted to say that I can’t see in this recipe etc where your note about Diamond Crystal Kosher Salt is. Why isn’t Morton ok ? I am making pesto in my new Cuisinart for the first time and trying hard to do everything right!
Oh sorry – I had not read any of the comments before I just wrote you, so I will use 1/2 as much or less salt! Thank you!!
I love your recipes and use many of them. Thank you for everything you do. I am so glad you have started making pesto! Your recipe ia exactly the same as mine which I have been making every summer for 50 years. The only difference is I never use lemon juice–I know some people use it so the pesto remains bright green. I blanch my basil for 5-10 seconds and plunge in cold water, drain and squeeze. Your pesto will stay bright green for days, on the counter, in the refrigerator or in the freezer. I don’t wash the leaves before blanching. The other change I have made since moving to Italy four years ago, that I learned while in Genova, the birthplace of Pesto, is: I now use 1/2 Pecorino Sardo (or Pecorino Romano) with 1/2 Parmigiana Reggiano, for the cheese. It is totally a game changer. I also freeze my pesto in silicon ice cube trays but I use 2″ square size – they come with lids and there are 6 squares to a tray- the size works better for me.
So nice to read all of this Sandra! Thanks so much for writing and sharing these notes. I am definitely going to try your method of blanching the basil leaves and then plunging them into cold water. I love the idea of preserving their bright green color and I know I would also love Pecorino because I love its saltiness.
This is my favourite pesto! Might be a silly question, but…I’m getting ready to make more and I’m out of Kosher salt. I have both fine and coarse sea salt. Would one be better than the other?
Great to hear 🙂 I think I would go with fine sea salt… just start with less in case it is saltier. You can always add more to taste.
That sounds great—thanks so much!
I’ve been using this recipe this year to make pesto. I especially like the fact that it has instructions for a large batch, as I plant quite a bit os basil.
I’ ve passed on pesto to my friends and family. They also like the results. Delicious!
I’m so happy to hear this, Barbara! I feel like large batch is the only batch for pesto 🙂 Same amount of work for so much more reward.
This is the only pesto recipe I use, even though I’ve never had enough basil to make the larger batch. I was curious how many cups it equals. I’ve started saving the recipes I regularly use in our family cookbook and wanted to make sure I had all the details right.
Thanks for the help!
Great to hear, Valeska 🙂 The basil itself is roughly 4 quarts loosely packed… see the photo in the post above. 4 quarts = 16 cups.
