Pesto Orzo Salad

There’s something almost magical about a bowl of pesto orzo salad on a warm afternoon. It’s the kind of dish that looks like you spent hours in the kitchen — bright green pesto clinging to tender pasta, pillowy chunks of fresh mozzarella, and bursts of sweet cherry tomatoes — but honestly? You’ll have it on the table in under 30 minutes. Whether you’re feeding a crowd at a backyard cookout or just want something satisfying for lunch, this one checks every box.

Why You Will Love This Pesto Orzo Salad:

• It’s genuinely quick. Between boiling the orzo and blitzing the pesto, you’re looking at maybe 25 minutes of actual effort. That’s weeknight-friendly territory, and still impressive enough for guests.
• You can make it your own. Think of this as a starting point, not a finish line. Swap proteins, toss in whatever vegetables are sitting in your crisper drawer, or dial up the lemon for more brightness. It bends to your preferences without breaking.
• The flavor combination is unbeatable. Herbaceous pesto, milky mozzarella, sweet tomatoes, and chewy orzo — it just works. Every bite has something going on, and it only gets better as it sits.
• It’s a garden lover’s dream. If you grow basil in the summer, this is one of the best ways to use a generous harvest. Pair that with a neighbor’s tomatoes (we all have that neighbor), and you’ve got a salad that tastes like summer in a bowl.

Recipe Ingredients:

• Orzo — A short, rice-shaped pasta that holds pesto beautifully. Look for it in the pasta aisle. In a pinch, small shells or ditalini work, but orzo is the classic choice here.
• Cherry or grape tomatoes — Halved or quartered, these bring a juicy pop to every forkful. Use whatever’s ripest at the market or in your garden.
• Baby spinach — Stirred into the warm, drained orzo, spinach wilts down almost instantly and adds a subtle earthiness without overwhelming the other flavors.
• Fresh mozzarella — Skip the pre-shredded bags. Fresh mozzarella — torn or chopped into rough chunks — has a creaminess that soaks up the pesto in the best way. Mozzarella pearls work too, though the irregular pieces cling to the dressing a little better.
• Fresh basil — The backbone of a good pesto. Dried won’t cut it here. Grab the freshest bunch you can find.
• Pine nuts — Toasted until golden, they add a subtle nuttiness to the pesto. Walnuts are a more budget-friendly substitute, and pepitas work well for anyone avoiding tree nuts.
• Extra virgin olive oil — Use something you’d actually enjoy dipping bread into. The quality makes a noticeable difference in a simple sauce like pesto.
• Fresh lemon juice — Brightens everything up. Bottled works, but fresh is always better, and a little zest goes a long way if you want extra pop.
• Garlic — A clove or two thrown right into the food processor does the trick. No need to mince by hand.
• Parmesan — Grated finely, it gives the pesto that savory, salty depth. Leave it out for a dairy-lighter version.
• Salt & pepper — Season generously and taste as you go.

Step-By-Step Instructions:

1. Get the orzo going. Bring a well-salted pot of water to a boil and cook the orzo to al dente — it’ll continue to soften slightly as it sits with the pesto, so don’t overcook it. While that’s happening, toast the pine nuts in a dry skillet over medium heat for 2–3 minutes, stirring constantly. They go from golden to burnt quickly, so don’t walk away. Spread them out to cool.

2. Make the pesto. Add the basil, garlic, and cooled pine nuts to a food processor and pulse until broken down into a rough paste. Scrape down the sides as needed. Add the lemon juice, salt, and pepper. With the processor running, slowly drizzle in the olive oil until the pesto comes together and is smooth but still has some body. Finish with the parmesan and pulse until fully incorporated.

3. Drain and wilt. Once the orzo is done, drain it and run a little cold water over it to stop the cooking. Add the baby spinach directly to the warm orzo — it’ll wilt from the residual heat. Transfer everything to a large mixing bowl.

4. Toss it all together. Add the halved tomatoes, chopped mozzarella, and about three-quarters of the pesto to the bowl. Toss until everything is evenly coated. If it looks dry, a splash more olive oil fixes that right away.

5. Chill before serving. Let the salad rest in the fridge until you’re ready to eat. Right before serving, drizzle on the reserved pesto and top with extra pine nuts and torn basil.

Tips Worth Knowing

• Keep the pesto loose. A thicker pesto is great for spreading on toast, but for this salad, you want it fluid enough to coat every piece of pasta. Add olive oil gradually until it pours easily.
• Toast those pine nuts. It takes two minutes and adds a depth of flavor that raw nuts just can’t deliver. Let them cool completely before adding to the pesto, or they’ll create steam and change the texture.
• Going nut-free? Pepitas (shelled pumpkin seeds) are an excellent swap — toast them the same way. Or skip the nuts entirely and reduce the olive oil by a tablespoon or so.
• Add lemon zest if you like a little zing. About a teaspoon stirred in before serving gives the whole dish a lift. It’s optional, but it’s a nice touch.
• This salad is actually better the next day. Make it ahead, hold back a little pesto, and stir it in fresh before you serve it. The flavors meld overnight in a way that’s hard to beat.

Ideas to Customize It

This salad is a great blank canvas. A few additions worth trying:

• Grilled chicken or shrimp for a heartier meal
• Diced red onion for a little sharpness
• Sliced cucumber or zucchini for crunch and freshness
• Chopped artichoke hearts
• Sun-dried tomatoes for a more intense, chewy bite
• Cannellini beans or chickpeas to keep it plant-based and filling
• A handful of arugula for peppery contrast
• Sliced olives for a briny kick
• More parmesan, always

How to Store It

Transfer leftovers to an airtight container and refrigerate for up to 3–4 days. Before serving from the fridge, let the salad sit at room temperature for 10–15 minutes — the olive oil in the pesto firms up when cold and needs a moment to loosen. A drizzle of fresh olive oil and a spoonful of reserved pesto before serving brings it right back to life.

Frequently Asked Questions

Can I use store-bought pesto instead of homemade?

Absolutely. A good quality jarred pesto will save you a few minutes and still produce a delicious result. That said, homemade pesto made with fresh basil has a brightness and flavor that’s tough to match from a jar — worth the extra step when you have the time.

Can I serve this warm instead of chilled?

Yes! While this salad is typically served cold or at room temperature, nothing is stopping you from enjoying it warm right after tossing. It’s a different experience, but still really good — especially in cooler months.

What can I use instead of orzo?

Small pasta shapes like ditalini, macaroni, or small shells all work well as substitutes. Just keep in mind that orzo’s slightly chewy texture holds up especially well in a dressed salad.

Is this recipe gluten-free?

Standard orzo contains gluten, but you can use a gluten-free orzo or a small rice-based pasta shape as a swap. Check that your other ingredients (like parmesan) are certified gluten-free if needed.

Can I make this vegan?

With a couple of swaps, yes. Use nutritional yeast in place of parmesan in the pesto, and swap the mozzarella for a plant-based alternative or skip it entirely and add more vegetables instead.

How far in advance can I make this?

Up to one day ahead is ideal. The salad actually improves overnight as the flavors meld. Just hold back a little pesto and add it right before serving to keep everything vibrant.

My salad looks dry after refrigerating — what happened?

The pasta absorbs the pesto and olive oil as it sits. This is completely normal. A drizzle of fresh olive oil and any leftover pesto stirred in just before serving will bring it back to the right consistency.
