This hearty Italian pasta salad has been my go-to potluck contribution for years, always disappearing faster than any other dish on the table. The colorful mix of tri-color rotini, fresh vegetables, savory salami, and cheese creates a symphony of flavors that will make your taste buds dance.
I first created this recipe when I needed something quick for an impromptu neighborhood barbecue. It was such a hit that neighbors started requesting "Chelsea's famous pasta salad" at every gathering thereafter.
Ingredients
- Tri color rotini pasta: gives this salad visual appeal and catches all the delicious dressing in its spirals
- Cherry tomatoes: bring a burst of sweetness and juicy texture choose the ripest ones you can find
- Black olives: add a briny flavor that balances the acidity perfectly
- Green bell pepper: provides a satisfying crunch and fresh flavor
- Red onion: contributes a sharp pungent flavor that mellows as it marries with the dressing
- Salami: delivers rich savory protein choose a good quality one for best results
- Fresh basil: elevates the entire dish with its aromatic qualities
- Mozzarella cheese cubes: add creamy texture and mild flavor
- Italian seasoning: ties all the Mediterranean flavors together
- Italian dressing: coats everything in tangy goodness use your favorite brand or homemade
Step-by-Step Instructions
- Cook the Pasta:
- Boil the tri-color rotini according to package directions until al dente usually about 7 to 9 minutes. Be careful not to overcook as firm pasta holds up better in salads. Immediately drain and rinse under cold water to stop the cooking process and remove excess starch. Allow to cool completely before proceeding.
- Mix the Ingredients:
- In a large bowl combine your cooled pasta with all remaining ingredients the cherry tomatoes black olives bell pepper red onion salami basil mozzarella and seasonings. The key here is making sure everything is evenly distributed so every bite has a perfect balance of flavors.
- Add the Dressing:
- Pour the Italian dressing over all ingredients and gently fold everything together until thoroughly coated. Take your time with this step to ensure every piece of pasta gets dressed without breaking apart the more delicate ingredients.
- Chill and Marry Flavors:
- Cover your bowl and refrigerate for at least 2 hours but overnight is even better. This resting time allows all the wonderful flavors to meld together and the pasta to absorb some of the dressing. This is what transforms it from good to extraordinary.

The mozzarella cheese is my secret weapon in this recipe. I prefer to use the low moisture variety cut into small cubes rather than fresh mozzarella which can become too watery when sitting in the dressing. My family particularly loves finding these little cheese treasures mixed throughout the salad.
Make Ahead Magic
This pasta salad actually improves with time making it the perfect make ahead dish. I often prepare it the night before serving to allow the flavors to fully develop. Just give it a quick stir before serving and if needed add a small splash of additional dressing to refresh it. The pasta will continue absorbing the dressing as it sits resulting in more concentrated flavors.
Seasonal Adaptations
While this recipe is written with classic ingredients you can easily adapt it based on what's in season. In summer add fresh corn kernels or diced zucchini. During fall try adding roasted butternut squash cubes for sweetness. Winter variations work well with sun dried tomatoes instead of fresh. Spring brings opportunities to add blanched asparagus pieces or fresh peas. The versatility is endless making this a year round favorite.
Serving Suggestions
This pasta salad shines as a side dish alongside grilled chicken sausages or burgers at a summer cookout. It also makes a satisfying lunch on its own especially on hot days when you want something cool and refreshing. For a stunning presentation serve it in a large glass bowl to showcase all the colorful ingredients and garnish with additional fresh basil leaves just before setting it on the table.
