Orzo Pesto Salad Tips and Tricks

How to Perfectly Cook Orzo

Orzo is prepared just like pasta and should be cooked al dente for the best bite. For perfect orzo, bring about 3 cups of water to a rolling boil before adding one cup of your uncooked orzo.

Boil the orzo and water for 8-10 minutes uncovered, stirring occasionally so that the orzo does not stick to the bottom of the pot or to each other.

After 8 minutes, test a noodle to see if it’s ready. If not, give it another 2 minutes maximum. Once it’s perfectly al dente, strain the orzo.

It’s best to toss the orzo with the pesto immediately, before it has a chance to stick together. As soon as you’ve strained the orzo, add it to a large bowl and stir in the pesto.

Keep in mind the orzo noodles are small, so make sure the holes in your colander are small enough to contain the orzo. You may want to use a sieve.

How to Prep Grape Tomatoes

After rinsing your grape (or cherry) tomatoes, all you have to do is slice them in half lengthwise.

When it comes to slicing tomatoes, if your knife isn’t extremely sharp, then it’s probably best to use a serrated knife or a tomato knife to more easily pierce the skin.

Season Your Grape Tomatoes Before Roasting

Add the prepped grape tomatoes to a baking sheet and spread them out. For less cleanup, you can opt to line the baking tray with aluminum foil.

Then, drizzle the olive oil on top and sprinkle on the salt and pepper.

Toss to Evenly Coat

Use clean hands to toss the tomatoes in the oil, salt, and pepper. I find that this is the easiest way to ensure they are all evenly coated.

If you’re not a fan of getting your hands dirty, you can use tongs or two large forks to toss everything together instead. Then, spread the coated tomatoes out in a single layer, ensuring none are not stacked on top of one another.

Roast the tomatoes at 425°F for 10-15 minutes until the skin starts to wrinkle.

Mix All Your Ingredients Together

Once your tomatoes are ready, add the mozzarella pearls and roasted grape tomatoes to the pesto orzo and mix to combine.

The hope is that the cheese and tomatoes are evenly distributed so you can get all of the flavors and textures in each and every bite.

Serving Your Pesto Orzo Salad

One of my favorite things about this orzo pasta salad is that it’s super no-fuss and versatile in terms of serving temperature. It’s delicious freshly made and hot, at room temperature (making it perfect for on-the-go!), and it’s even delicious cold right out of the refrigerator.

It brings tons of bold flavor and can be served as a meal all on its own, but if you want to add a protein, here are some of my favorites:

How to Store Your Orzo Pesto Salad

Leftover Orzo Pesto Salad will last up to 5 days in an airtight container in the refrigerator or up to 3 months in the freezer.

You can eat leftovers cold right out of the fridge! If you do freeze leftovers, make sure to allow them to thaw overnight in the refrigerator before enjoying.

Green tip: Billions of tons of food is wasted annually. Combat food waste by reducing the amount of waste you produce in your own home by properly storing food and leaving little to no leftovers.

Pro Tips

  • Watch your tomatoes closely—burnt tomatoes can taste really bitter. If you do burn your tomatoes, consider tossing them in a little bit of honey or maple syrup to balance out that bitterness.
