This Summer Pesto Pasta Salad transforms the season's freshest ingredients into a crowd-pleasing dish that's perfect for outdoor gatherings. The vibrant combination of garden basil, juicy tomatoes, and creamy mozzarella creates a pasta salad that celebrates summer's bounty in every bite.
I first made this pasta salad for a spontaneous backyard gathering last July when temperatures soared above 90 degrees. The cool refreshing flavors were such a hit that it's now requested at every summer potluck our family attends.
Ingredients
- Fusilli pasta: spiral shape captures more pesto in every bite
- Cherry tomatoes: their natural sweetness intensifies at room temperature
- Fresh mozzarella pearls: adds creaminess that balances the herby pesto
- Basil pesto: homemade delivers the brightest flavor but quality storebought works wonderfully too
- Olive oil: use extra virgin for the richest flavor
- Grated Parmesan: adds a salty nutty dimension
- Fresh basil leaves: brighten the finished dish with color and aroma
Step-by-Step Instructions
- Cook the Pasta:
- Boil pasta in heavily salted water until just al dente usually a minute less than package directions suggest. Immediately rinse under cold water to stop the cooking process completely. This prevents the pasta from becoming mushy while it sits in the dressing.
- Prepare the Vegetables:
- Slice cherry tomatoes in half to release their sweet juices which will mingle with the pesto creating an even more flavorful sauce. If using larger mozzarella balls quarter them to ensure each bite contains a perfect balance of ingredients.
- Mix the Dressing:
- Combine pesto with olive oil in a small bowl to thin it slightly which helps it coat every piece of pasta evenly. The olive oil creates a silkier texture that clings beautifully to the pasta curves.
- Assemble the Salad:
- Gently fold all ingredients together in a large bowl starting with pasta then adding tomatoes mozzarella and finally the pesto mixture. Use a spatula rather than a spoon to prevent breaking the delicate mozzarella pieces or crushing the tomatoes.

The aromatic basil in this dish always reminds me of my grandmother's garden where she grew enormous basil plants each summer. She taught me that handling basil gently and tearing rather than cutting preserves its essential oils and fragrance something I still practice when making this salad.
Perfect Pesto Selection
Homemade pesto delivers unmatched freshness but not everyone has time to make it from scratch. When shopping for storebought versions look for those with the brightest green color usually found in the refrigerated section rather than shelf stable varieties. The color indicates fresher basil and less processing. For an unexpected twist try sun dried tomato pesto or arugula pesto which both work beautifully in this recipe.
Make It Your Own
This pasta salad welcomes customization based on what you have available. Add protein like grilled chicken or cannellini beans for a heartier main dish. Vegetables like blanched asparagus roasted red peppers or baby spinach add extra nutrition and color. For a Mediterranean twist include kalamata olives artichoke hearts and feta cheese instead of mozzarella. The pasta salad will happily accommodate your creativity while maintaining its summery essence.

Serving Suggestions
This versatile dish pairs beautifully with grilled meats particularly simple chicken or steak that won't compete with its flavors. For a complete vegetarian meal serve alongside a chickpea salad or fresh fruit. While delicious cold it also works at room temperature making it ideal for buffet settings. To refresh leftovers from the refrigerator allow the salad to sit at room temperature for 15 minutes before serving and drizzle with a touch of extra olive oil to revive its silky texture.
Common Recipe Questions
- → Can I make this pasta salad ahead of time?
Absolutely! This pasta salad actually improves with time as the flavors meld together. You can make it up to 24 hours in advance and store it in the refrigerator. Just give it a quick toss before serving to redistribute the dressing.
- → What's the best pasta shape to use?
Short pasta shapes that have ridges or twists work best as they hold the pesto sauce well. Fusilli, rotini, penne, farfalle (bow ties), or orecchiette are excellent choices. Avoid long pasta like spaghetti which can be difficult to serve and eat in a cold salad format.
- → Is homemade or store-bought pesto better?
While homemade pesto offers the freshest flavor with customizable ingredients, high-quality store-bought pesto works perfectly fine and saves time. If using store-bought, look for refrigerated varieties rather than shelf-stable options for better flavor.
- → How long will this pasta salad keep in the refrigerator?
This pasta salad will keep well in an airtight container in the refrigerator for 3-4 days. The pasta may absorb some of the moisture over time, so you might want to add a drizzle of olive oil if serving leftovers.
- → Can I add other vegetables or ingredients?
Absolutely! This pasta salad is versatile and works well with many additions. Consider adding cucumber, bell peppers, artichoke hearts, olives, pine nuts, or even protein like grilled chicken or chickpeas to make it more substantial.
- → Should I rinse the pasta for this salad?
Yes, unlike hot pasta dishes where you typically shouldn't rinse pasta, for cold pasta salads it's recommended to rinse the cooked pasta under cold water. This stops the cooking process immediately and removes excess starch, preventing the pasta from sticking together.
