A Tuna Pesto Pasta Recipe with Arugula Spinach Pesto

A Tuna Pesto Pasta Recipe with Arugula Spinach Pesto

This tuna pesto pasta recipe with arugula spinach pesto was inspired by the linguine with tuna, lemon, and rocket (Linguine al Tonno, Limone, e Rughetta) that I first made with Diane Seed in Rome over a decade ago. It’s a quick and simple weeknight pasta that I have been making ever since.

It was only by chance that I ended up in Italy. I was supposed to go to Peru, but landslides closed Machu Picchu. And so a last minute change in plans sent me to Rome and Venice, two cities I didn’t expect to love half as much as I did. Throughout my blog, you’ll see lessons I learned in Rome during three days of one on one cooking in Diane Seed’s kitchen.

I typically use pine nuts in my pesto, like in this kale pesto. But I use walnuts in this arugula spinach pesto for a couple reasons. I think the walnuts better match the astringency in the greens. Also, the increasing demand for pine nuts has resulted in deforestation of the pine trees that these “nuts” come from and loss of important ecosystem. You can read more about that here and here.

FAQs about this tuna pesto pasta recipe

Where can I find the original recipe?

The linguine with tuna, lemon, and rocket that inspired this tuna pesto pasta recipe can be found in The Top One Hundred Pasta Sauces by Diane Seed.

Can I freeze the arugula spinach pesto?

Yes, pesto freezes perfectly in tupperware type containers. Or freeze it in ice cube trays to add small amounts to eggs or other dishes.

What else could I do with this pesto?

In addition to using pesto in egg dishes, I like pesto as a sandwich spread, as a base for pizza, or even in a babka.

I’m allergic to walnuts. Are there other nuts I could use?

Pine nuts are traditional in pesto. Or you could use almonds or pistachios or other nuts.

Could I use only arugula or only spinach in the pesto?

Yes. The original recipe calls for only arugula, so feel free to use that or only spinach. Using all arugula will give the pesto a more peppery flavor.

Is there a reason to use tuna packed in oil?

Tuna packed in oil is generally moister, more tender, and more flavorful than tuna packed in water, but you can certainly sub tuna packed in water if that is what you have.

What are the best pasta shapes to use in this recipe?

Because of the tuna, I like this best with short chunky shapes. And then I want a shape that will catch the pesto, like fusilli or cavatappi. Or this might be the perfect recipe for your cascatelli, if you can get your hands on any.
