There are not many components to this pesto orzo salad recipe, so the key is to use the freshest ingredients you can find. Your basil pesto and your tomatoes should sing of summer.


What is orzo?

Orzo literally means “barley” in Italian. It’s a small wheat pasta shaped like barley or rice. Orzo is often used in soup recipes but can be cooked the same way as Arborio in risotto or to make an orzo salad like this recipe.

About fresh mozzarella

Perlini mozzarella are the smallest size of mozzarella balls, about a centimeter in diameter. They are supposedly the size of pearls, though I can’t imagine a necklace made out of pearls that size!

If you’re unable to find perlini, use the smallest mozzarella you can find. Chop it if you have to. But please use fresh mozzarella in this pesto orzo pasta salad recipe and save the dried, shredded mozzarella for your pizza recipes.

Variations and substitutions

  • If you can’t find orzo, any small pasta shape will work in this pasta salad recipe.
  • Add spinach or other greens or finely chopped basil leaves to the pasta salad.
  • Chop some artichoke hearts or steamed green vegetables like broccoli or asparagus into the salad.
  • Add white beans for protein or add chopped roasted chicken breast to make this a chicken pesto salad.

Tips and tricks

Making the pesto orzo salad

Step 1: To make this orzo salad recipe, bring a large pot of water to a boil and then add your salt. Adding salt after the water is boiling helps prevent the salt from pitting your pots.

Step 2: When the water returns to a boil, cook the orzo to al dente, save a cup or so of pasta water, and drain the orzo. Return the orzo immediately to the warm pot and mix the orzo with pesto and some pasta water until it gets to your desired consistency.

Tip from the wisequacker: as a rule of thumb, combine your pasta and sauce in the pot and cook them a minute or two. With pesto, the pasta needs just to be warm. When your pasta takes up flavor from the sauce, it tastes better! Stay away from pasta recipes that stir pesto into cold pasta or show pasta sauce sitting pristinely on a pile of spaghetti.

Step 3: Let the pesto-coated orzo cool to room temperature before adding the other ingredients for the orzo salad. Serve immediately. Easy!

Recipe FAQs

Why do you toast the pine nuts?

Toasting the pine nuts that will be used to garnish this pesto orzo salad enhances their flavor and makes them crunchier. I always recommend toasting your nuts, whether it’s for baking like in this coffee and walnut loaf cake or for savory dishes like pesto or meatball recipes.

How do you toast pine nuts?

The easiest way to toast pine nuts is to put them in small pan in a hot oven for five to ten minutes. You can also heat them in a dry frying pan over low heat. Either way, be careful not to burn them. They should be lightly colored and smell toasty.

How far ahead can I make this pesto orzo salad?

The simplest way to make this ahead is to make the pesto in advance. Pesto can be frozen for months. Fully made, the pesto orzo salad is best served within the first day, but it can be stored in the refrigerator for several days.

What can I make with leftover pesto?

Pesto is of course fabulous as a pesto pasta, but you can also use leftover pesto as an alternative to pizza sauce, swirled into a potato soup, or as the base for a creamy pesto dressing.

When you drain the orzo, reserve a cup of pasta water. Then drain and mix the orzo with pesto while the orzo is still warm, using pasta water to thin the pesto as necessary. This way the orzo absorbs the sauce and your orzo salad tastes so much better!
Lightly toasting pine nuts brings out their flavor and makes a crunchier garnish for the pesto orzo salad.
