When life gives you basil, make this pesto pasta salad recipe!

It’s my favorite time of year: the time when our deck turns into a verdant garden. We have thriving pots of kale and tatsoi, twisting vines of summer squash, cherry tomatoes, a fig tree(!), and ALL the herbs. Our basil plants have been doing especially well lately, which is fine by me, because in mid-July, there’s nothing I’d rather eat.

I first made this pesto pasta salad late last week, when I was dreaming up ways to use the pile of basil I’d just picked. I was in the mood for something light, yet satisfying, fresh, and fun, and this pesto pasta salad completely hit the spot. Jack and I shared it for lunch, and neither of us could resist going back for seconds. …Ok, more like thirds. 🙂

Pesto pasta salad recipe ingredients

Pesto Pasta Salad Recipe Ingredients

To let the fresh basil flavor shine, I keep this pesto pasta salad recipe simple. It only calls for a handful of ingredients:

  • Pasta, of course! I recommend choosing a fun, curly pasta shape. We love cellentani, but fusilli would be good too.
  • Basil Pesto – To give the pasta salad a lightly creamy texture, I add an extra 1/4 cup olive oil to my regular basil pesto recipe.
  • Zucchini and summer squash – You’ll be adding them to the salad raw, so make sure to slice them really thinly. I recommend using a mandoline if you have one.
  • Lemon juice – It makes the salad nice and bright.
  • Toasted pine nuts – For crunch.
  • Fresh basil leaves – They’re a pretty, aromatic finishing touch for this pesto pasta salad.
  • And salt and pepper – To make all the flavors pop!

If you like, you can add a pinch of red pepper flakes for a hint of spice.

How to Make Pesto Pasta Salad

To make this pesto pasta salad, you’ll start by cooking the pasta in a large pot of salted boiling water.

  • Make sure to cook it a little past al dente so that it doesn’t harden as it cools.
  • And before you drain it, reserve 3/4 cup of the starchy, salty pasta cooking water. It’s a key ingredient in this recipe – it helps the pesto coat the noodles and veggies, creating a rich, lightly creamy pesto sauce for the salad.

After you drain the pasta, toss it with a little olive oil and spread it on a large baking sheet to cool. Allow the reserved pasta water to cool too.

When the pasta is cool, add it to a large bowl with the pesto, zucchini, squash, lemon juice, salt, and pepper. Last but not least, add the reserved pasta water and toss to combine.

Season to taste, and top with the pine nuts, basil, and a pinch of red pepper flakes, if you like. Enjoy!

Pesto Pasta Salad Serving Suggestions

I typically think of pasta salad recipes as side dishes, but this one is so fresh and satisfying that it could easily pass as lunch or a light summer dinner. Pair it with a simple green salad, a chopped salad, or grilled veggies. If you’re really flush with basil, it’d be delicious with a Caprese salad, too.

That being said, you shouldn’t hesitate to serve this recipe as a side dish at a potluck or picnic. It’s great with all the cookout classicsveggie burgers, corn on the cob, fruit salad, you know the drill. It’s guaranteed to be a hit!

I love this recipe as written, but if you want to get creative with it, feel free. Try tossing in mini fresh mozzarella balls, shaved pecorino, or sun-dried tomatoes. Roasted cherry tomatoes would be a delicious addition too. Let me know what variations you try!

*I like to slice these on a mandoline so that my slices are thin enough to enjoy raw in this pasta salad.

    I’ve made this several times now and my family and I love it… such a quick fix for a work-day meal!
    While I love this recipe as-is, I did mix it up a bit for dinner tonight and lightly sauteed the squash with some onions, garlic and chick-peas. We have company that doesn’t care for raw squash, so I made a compromise, then added the rest to make this a more filling meal that would stretch a bit for the extra person. In the past, I have also added grated carrot, peas, etc. Very flexible recipe!!!
