This summer pesto pasta salad brings the taste of sunlit gardens to your table with minimal effort. Bursting with fresh flavors and vibrant colors, it's my go-to dish when temperatures rise and cooking enthusiasm wanes. The combination of cool pasta, juicy tomatoes, and creamy mozzarella creates a refreshing meal that works equally well as a light dinner or potluck contribution.
I first created this pasta salad for my daughter's graduation party when temperatures hit 95 degrees. The guests devoured it so quickly I barely got a serving for myself. Now it's requested at every summer gathering we host.
Ingredients
- Short pasta like fusilli or rotini to capture maximum pesto in every bite
- Cherry tomatoes for bursts of juicy sweetness that balance the herby pesto
- Fresh mozzarella pearls adding creamy texture without overwhelming other flavors
- Basil pesto providing the aromatic herb base that brings everything together
- Olive oil to loosen the pesto and create a silky coating
- Parmesan cheese for that umami richness and depth
- Salt and pepper to elevate all flavors
- Fresh basil leaves adding bright color and fragrant finish
Step-by-Step Instructions
- Cook the Pasta
- Boil pasta in heavily salted water until just al dente about 9-10 minutes. The pasta should have a slight firmness when bitten. Immediately drain and rinse under cold water until completely cool. This stops the cooking process and prevents sticking. Let drain thoroughly as excess water will dilute your pesto.
- Toss the Salad
- Combine cooled pasta with halved cherry tomatoes and mozzarella in a large bowl. Use gentle folding motions to prevent breaking the mozzarella or crushing the tomatoes. The pasta should be completely cool before adding cheese to prevent melting.
- Add the Pesto
- Pour pesto and olive oil over pasta mixture. Add grated Parmesan if using. Fold everything together using wide gentle strokes until every piece of pasta is coated with the vibrant green sauce. The olive oil helps the pesto distribute evenly while keeping the pasta from sticking together.
- Season and Garnish
- Taste and adjust seasoning with salt and freshly ground black pepper. The pasta absorbs flavor as it sits so be slightly more generous than you might think necessary. Tear fresh basil leaves and scatter over the top just before serving for maximum visual appeal and aromatic impact.

This salad reminds me of summer evenings in my grandmother's garden in Italy. She always said the secret to perfect pesto pasta was adding a splash of the pasta cooking water to the pesto to help it cling to every curve of the pasta. Though this cold version skips that step, the memory of her hands tearing fresh basil stays with me every time I make it.
Storing Leftovers
This pasta salad maintains its quality exceptionally well in the refrigerator. Store in an airtight container for up to 4 days. The flavors actually develop and meld together beautifully overnight, making it taste even better the next day. If the pasta seems to have absorbed too much of the dressing, rejuvenate it with a small drizzle of olive oil and gentle toss before serving again.
Customize Your Salad
The beauty of this recipe lies in its adaptability. Add protein like grilled chicken or chickpeas for a heartier meal. Incorporate vegetables such as roasted red peppers, artichoke hearts, or steamed asparagus pieces to increase nutritional value. For a vegan version, substitute the mozzarella with firm tofu cubes marinated in lemon juice and herbs, and use nutritional yeast instead of Parmesan.
Serving Suggestions
While delicious on its own, this pasta salad pairs wonderfully with grilled meats or seafood for a complete meal. Serve it alongside bruschetta or focaccia bread for an Italian-inspired spread. For a lovely presentation at gatherings, serve in a large shallow bowl lined with fresh greens like arugula or spinach, allowing the vibrant colors to pop against the darker background.
Make Your Own Pesto
While store-bought works perfectly fine, homemade pesto elevates this dish to new heights. Blend 2 cups fresh basil leaves, 1/3 cup pine nuts, 2 garlic cloves, 1/2 cup olive oil, and 1/2 cup grated Parmesan until smooth but still slightly textured. Making pesto in larger batches during basil season and freezing portions ensures you always have fresh-tasting pesto available.

Frequently Asked Questions About Recipes
- → Can I make this pasta salad ahead of time?
Absolutely! This pasta salad actually improves as it sits, making it perfect for make-ahead preparation. You can prepare it up to 24 hours in advance and store it in the refrigerator. Just give it a quick toss before serving to redistribute the pesto sauce.
- → What's the best pasta shape to use for this salad?
Short pasta shapes that can hold the pesto sauce work best. Fusilli, rotini, penne, or bow ties (farfalle) are ideal choices as their nooks and crannies capture the sauce and small ingredients. Avoid long pasta like spaghetti or linguine which can be more difficult to serve and eat cold.
- → How long will this pasta salad keep in the refrigerator?
When stored in an airtight container in the refrigerator, this pasta salad will keep well for 3-4 days. The flavors actually continue to develop during this time, though the pasta may absorb some of the moisture from the pesto sauce.
- → Can I use store-bought pesto instead of homemade?
Yes, high-quality store-bought pesto works perfectly in this dish and is a great time-saver. If using store-bought, you might want to brighten it up with a squeeze of lemon juice and some extra fresh basil leaves to give it that homemade touch.
- → How can I make this pasta salad dairy-free or vegan?
To make this dairy-free or vegan, use a plant-based pesto (made without Parmesan) and substitute the mozzarella with a dairy-free alternative like cubed avocado, white beans, or vegan cheese. You can make your own vegan pesto by replacing the Parmesan with nutritional yeast for that savory flavor.
- → What can I add to this pasta salad for extra protein?
Great additions for extra protein include diced grilled chicken, canned tuna, chickpeas, white beans, or even salami cubes. For vegetarian options, consider adding toasted pine nuts or walnuts which complement the pesto flavors beautifully.
