This vibrant Italian Pasta Salad has been my go-to dish for summer gatherings and potlucks for years. The colorful mix of crisp vegetables, tender pasta, and zesty dressing creates a refreshing meal that's as beautiful as it is delicious.
I first created this pasta salad for a neighborhood block party where it disappeared in minutes. Since then, it's become my most requested contribution to family gatherings, especially during warm weather months.
Ingredients
- Cooked pasta: The backbone of this salad. Choose shorter shapes like rotini or penne that capture the dressing in their ridges and crevices.
- Cherry tomatoes: These little bursts of sweetness add juicy freshness. Look for firm, deeply colored varieties for best flavor.
- Black olives: Their briny flavor adds a Mediterranean touch. I prefer kalamata olives for more complex flavor but regular black olives work beautifully too.
- Red bell pepper: Adds sweet crunch and vibrant color. Select peppers that feel firm and heavy for their size.
- Red onion: Provides a gentle bite that balances the other flavors. Soak in cold water for 10 minutes if you prefer to mellow the sharpness.
- Fresh basil: The aromatic herb that elevates this from good to extraordinary. Use only bright green leaves with no brown spots.
- Mozzarella cheese: Creamy pockets of mild cheese complement the tangy dressing. Fresh mozzarella balls offer the best texture and flavor.
- Italian dressing: The flavorful coating that brings everything together. Choose a high quality bottled version or make your own for even better results.
- Olive oil: Adds richness and helps the dressing cling to the ingredients. Extra virgin olive oil provides the best flavor profile.
- Dried oregano: A classic Italian herb that infuses the salad with authentic flavor. Crush between your fingers before adding to release more aroma.
- Garlic powder: Provides savory depth without overwhelming. Fresh minced garlic can be substituted if you prefer a more pronounced garlic flavor.
- Salt and pepper: The essential seasoning duo that enhances all the other flavors. Sea salt and freshly ground black pepper yield the best results.
Step-by-Step Instructions
- Cook the Pasta:
- Boil your pasta according to package directions until just al dente. Remember to salt your pasta water generously as this is your only opportunity to season the pasta itself. Once cooked, immediately drain and rinse under cold water to stop the cooking process and prevent sticking.
- Prepare the Vegetables:
- While the pasta cooks, prepare all your vegetables. Cut cherry tomatoes in half, allowing their juices to release into the salad. Slice olives uniformly for consistent flavor distribution. Dice the red bell pepper into small pieces approximately the same size as the halved tomatoes for visual appeal and balanced texture.
- Combine Base Ingredients:
- In a large mixing bowl, combine the cooled pasta with all the prepared vegetables. The pasta should be completely cool before adding the vegetables to prevent wilting or cooking the fresh components.
- Add Cheese and Herbs:
- Gently fold in the cubed mozzarella and freshly chopped basil. The cheese should be added in small cubes about half an inch in size for perfect bite sized pieces. The basil should be torn or chopped just before adding to preserve its aromatic oils.
- Create the Dressing:
- In a separate small bowl, whisk together the Italian dressing, olive oil, dried oregano, garlic powder, salt and pepper until thoroughly combined. This ensures even distribution of herbs and spices throughout the dressing.
- Dress the Salad:
- Pour the prepared dressing over the pasta mixture and toss gently but thoroughly using two large spoons or spatulas. Be careful not to stir too vigorously which could break down the delicate ingredients.
- Chill and Marinate:
- Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, though 2 hours is ideal. This resting period allows the flavors to blend and intensify while the pasta absorbs some of the dressing.
- Final Toss:
- Before serving, give the salad one final gentle toss to redistribute any dressing that may have settled at the bottom of the bowl. Taste and adjust seasonings if necessary.

The fresh basil is truly the star ingredient in this recipe. I grow it in my garden specifically for dishes like this pasta salad. One summer when my basil plant was particularly abundant, I made this salad three weekends in a row for different gatherings, and each time people asked for the recipe.
Make Ahead Magic
This pasta salad actually improves with time, making it perfect for advance preparation. You can prepare the entire salad up to 24 hours before serving, which allows the flavors to marry beautifully in the refrigerator. If making more than a day ahead, consider reserving some of the dressing to refresh the salad just before serving, as the pasta will continue to absorb liquid as it sits.
Perfect Pairings
Italian pasta salad works wonderfully alongside grilled meats, particularly chicken, steak or Italian sausages. The acidity in the dressing cuts through rich foods beautifully. For a complete summer spread, serve alongside bruschetta, grilled vegetables, and a light fruit dessert. A chilled rosé or Pinot Grigio complements the Mediterranean flavors perfectly.
Creative Variations
This recipe serves as an excellent base for countless variations. For a protein boost, add diced salami, pepperoni, or grilled chicken. Vegetable options are equally flexible consider artichoke hearts, roasted red peppers, or marinated mushrooms. Cheese lovers might enjoy experimenting with provolone, feta, or sharp parmesan in place of the mozzarella. The beauty of this salad lies in its adaptability to whatever ingredients you have on hand.
Recipe FAQs
- → How long does Italian pasta salad keep in the refrigerator?
Italian pasta salad keeps well in an airtight container in the refrigerator for 3-5 days. The flavors actually continue to develop and improve after the first day, making this a perfect make-ahead dish. Just give it a quick toss before serving to redistribute the dressing.
- → Can I make this pasta salad ahead of time?
Absolutely! This pasta salad is ideal for making ahead. In fact, allowing it to chill for several hours or overnight helps the flavors meld together beautifully. If preparing more than a day ahead, consider adding the fresh herbs just before serving to maintain their vibrant color and flavor.
- → What are the best pasta shapes to use in this salad?
Short pasta shapes with ridges or curves work best as they catch and hold the dressing effectively. Rotini, fusilli, farfalle (bow ties), penne, or orecchiette are excellent choices. Avoid long pasta like spaghetti or linguine as they don't mix as well with the other ingredients.
- → How can I make this pasta salad more filling?
To transform this into a heartier main dish, add protein such as grilled chicken, salami, pepperoni, tuna, or chickpeas. You could also incorporate additional cheeses like provolone or parmesan, or toss in some marinated artichoke hearts or roasted red peppers for extra flavor and substance.
- → Can I use store-bought Italian dressing?
Yes, store-bought Italian dressing works perfectly for convenience. Choose a high-quality option for the best flavor. If using bottled dressing, you may want to taste and adjust the seasonings as needed, perhaps adding a splash of fresh lemon juice or a drizzle of extra virgin olive oil to brighten the flavors.
- → Is this pasta salad served hot or cold?
This Italian pasta salad is traditionally served cold or at room temperature, making it perfect for warm weather, picnics, potlucks, and meal prep. The chilling time allows the flavors to develop and meld together beautifully.
