Cook the Pasta
Bring a large pot of generously salted water to a boil. Cook pasta until al dente according to package instructions, about 8–10 minutes.

Toss Thoroughly
Stir gently but thoroughly to evenly coat all ingredients in dressing and seasoning.
Chill for Flavor Development
Cover and refrigerate for at least 1 hour before serving to allow flavors to meld and deepen.
Adjust and Serve
Before serving, taste and adjust seasoning or add extra dressing if needed.

Why This Recipe Works
The ridges of rotini pasta trap the dressing, ensuring every bite is coated in bold Italian flavor. Cooling the pasta stops residual cooking and preserves texture, while the mix of briny olives, tangy peppers, and savory pepperoni creates layered contrast. Allowing the salad to chill gives the starches time to absorb the dressing, intensifying flavor throughout. At roughly 375 calories per serving, this pasta salad delivers satisfying richness while remaining light enough for a side dish.
Final Thoughts
Italian Pasta Salad is a timeless, versatile dish that brings color, texture, and big flavor to any table. Whether served as a main lunch option or a vibrant side, it’s a dependable favorite that improves with time. For a lighter version, reduce the dressing slightly or increase vegetable content while keeping the bold Italian character intact. However you customize it, this pasta salad is guaranteed to disappear fast.
