Bright basil, twirls of pasta, and soft mozzarella make Pesto pasta salad the dish that disappears first.
This version leans on a big, punchy homemade pesto and a whisper of mayonnaise for gloss and next-day magic.
Juicy tomatoes and peppery rocket keep every bite fresh, while al dente spirals grab and hold all that green.
Cook the pasta just past al dente, then rinse it cool and toss with pesto so it coats rather than clumps.
A little extra oil keeps it luscious without heaviness, and the bocconcini go in last to stay tender.
Serve it now or chill for picnics, potlucks, and easy lunches that still taste like summer.
What you’ll need for pesto pasta salad
- Choose spiral pasta such as fusilli, because ridges and curves trap pesto so every bite tastes seasoned and saucy.
- Make homemade basil pesto—bold, thick, and fragrant—with toasted pine nuts, garlic, parmesan, and extra-virgin olive oil so it clings.
- Add just 2 tablespoons of mayonnaise for light creaminess and next-day moisture.
- Halve cherry tomatoes for juicy sweetness and a fresh, bright counterpoint to the herbs.
- Use baby bocconcini for milky, tender pearls that soften and balance the basil.
- Add rocket, also called arugula, for a peppery lift that keeps the salad lively.
- Finish with kosher salt and black pepper so the flavors pop.
Olive oil and mayo keep the salad juicy
Pesto needs fat to travel, because fat carries basil’s aroma across the pasta.
A generous 7 tablespoons of olive oil in the pesto, plus a modest 2 tablespoons of mayonnaise, create a silky coating. It will not seize when the salad chills.
Rinse the pasta cold to stop cooking, then drain and air-dry so the sauce adheres rather than diluting.
The mayo does not make it creamy. It subtly emulsifies the oil, prevents next-day dryness, and gives a glossy, well-seasoned finish without heaviness.

Choose the right pasta shape for maximum cling
Short, textured shapes—fusilli, rotini, gemelli, or casarecce—offer grooves and twists that grip pesto.
Bowties work, but ridged spirals hold more sauce and travel better in lunch boxes.
Since chilling firms pasta, cooking it one extra minute gives a tender bite later.
Rinsing under cold water removes excess surface starch, which can turn gummy in a cold salad. It also stops carryover cooking instantly.
Let the pasta dry for a few minutes before tossing so the pesto coats instead of slipping off.
Smart swaps & little upgrades
Tiny tweaks protect brightness and balance.
Toast the nuts for deeper flavor, and pulse the pesto just enough—over-blending can darken basil and taste flat.
Season the tomatoes lightly so their juices mingle with the pesto instead of watering it down.
Pat bocconcini dry, add rocket at the end, and serve closer to room temperature for the fullest basil aroma.
Flavor boosters amplify pesto
Citrus and heat are the easiest ways to energize the bowl without crowding out the basil.
Add a touch of lemon zest, a squeeze of juice, or a pinch of red pepper flakes. These wake up the parmesan and keep the salad from tasting heavy.
If you want more substance, fold in grilled zucchini, roasted cherry tomatoes, or shredded rotisserie chicken after the pesto has fully coated the pasta.
These add-ons bring smoky sweetness and extra texture without stealing the spotlight.
Storing, serving, and reviving leftovers
Refrigerate in an airtight container for up to two days; basil will darken slightly, but the flavor stays bright if sealed well.
For best texture, pull it from the fridge 20–30 minutes before serving.
Toss with a drizzle of olive oil to loosen, then add fresh rocket or basil to restore that just-made look.
Avoid freezing, because fresh basil, tomato, and mozzarella do not thaw gracefully.
Room-temperature serving restores flavor and texture
Cold mutes pesto and tightens mozzarella.
Let leftovers shed their chill on the counter until the pasta feels supple and fragrant again.
A spoonful of olive oil and, if needed, a tiny dab of mayo bring back gloss without turning the salad heavy.
Hold delicate greens and any extra basil until just before eating so they stay perky. Then re-season with a pinch of salt to reawaken the tomatoes.
Frequently Asked Questions (FAQ)
Can I use store-bought pesto?
Yes—choose a refrigerated pesto for fresher basil flavor and better color. Use just shy of one cup and taste for salt; jarred versions vary, so you may need a squeeze of lemon or a drizzle of oil to balance.
What if I need a nut-free pesto?
Swap pine nuts for sunflower seeds, or omit them entirely and add 1–2 tablespoons of extra parmesan for body. The texture will be slightly looser, so pulse only briefly and toss while the pasta is well-drained.
Can I add protein without overpowering the salad?
Absolutely—shredded rotisserie chicken, grilled shrimp, or chickpeas are all gentle additions. Fold them in after coating the pasta with pesto so they pick up flavor without breaking the emulsion.
How do I make it gluten-free?
Use a short, sturdy gluten-free pasta such as corn-rice or brown-rice blends, because they hold up best. Cook just past al dente, rinse cold, and toss with a little oil before the pesto to prevent sticking and crumbling.
Pesto Pasta Salad
Ingredients
- 1 cup tightly packed baby arugula (rocket) leaves (approx. 40g)
- 2 tablespoons mayonnaise preferably S&W or Hellman’s
- 220 g 7 oz baby bocconcini, halved and drained
- 250 g heaped 1 cup cherry tomatoes, halved
- 350 g 12 oz spiral pasta such as fusilli (approx. 3½ cups)
- 1 tablespoon salt for boiling pasta
- Small basil leaves for garnish (optional)
- ½ teaspoon cooking or kosher salt
For the Pesto:
- ½ teaspoon cooking or kosher salt
- ½ cup finely grated parmesan cheese
- 2 tablespoons toasted pinenuts or substitute walnuts, cashews, almonds
- 2 cups tightly packed fresh basil leaves
- 7 tablespoons extra virgin olive oil or 50/50 blend with grapeseed oil
- ¼ teaspoon black pepper
- 1 small garlic clove minced
Instructions
- Bring 3 litres of water to a rolling boil and add the salt. Cook the pasta according to package instructions, plus one additional minute. Drain using a colander, rinse thoroughly under cold water, and shake off any excess moisture. Allow the pasta to fully cool and dry.
- To prepare the pesto, combine basil leaves, parmesan, toasted pinenuts, garlic, salt, pepper, and olive oil in a narrow container suitable for an immersion blender. Blend until mostly smooth—aim for a textured consistency with small green flecks rather than a completely uniform puree.
- Transfer the cooled pasta into a large mixing bowl. Spoon in the prepared pesto and add the mayonnaise. Toss thoroughly to coat all the pasta. Gently mix in the halved bocconcini and cherry tomatoes, stirring just enough to distribute evenly. Add the arugula and lightly fold through to incorporate.
- Transfer the salad to a serving dish and scatter with fresh basil leaves if using. Serve at room temperature for best flavor and texture.
