Zesty Italian pasta salad is the kind of dish that quietly becomes the star of the table - and you can make it two ways. Use crisp-tender cauliflower for a low carb, keto-friendly salad, or bowtie pasta for the classic. Either way, it's packed with pepperoni, mozzarella, olives, and fresh basil in a bold, zesty Italian dressing.

Two ways to make it:
- With cauliflower: low carb and keto-friendly, about 4 grams of net carbs per serving.
- With bowtie pasta: the classic potluck version, about 22 grams of net carbs per serving.
Same dressing, same mix-ins. The recipe card shows you how to make both.
The backstory.
Italian pasta salad has always been a classic pasta dish that shows up everywhere - backyard cookouts, potlucks, and that one friend's house who always seems to host the best summer dinners. I wanted a version that kept those classic flavors but felt a little fresher and lighter. That's where this combo came in: juicy tomatoes, creamy mozzarella, olives, pepperoni, and plenty of zesty Italian dressing tossed together into one bold, satisfying bowl.

Customize it your way.
Zesty Italian dressing pasta salad is easy to customize depending on what you have on hand or what flavors you love most.
- Swap bowtie pasta for rotini, penne, or shells for a different texture.
- Add sliced red onion for a little extra bite and color.
- Toss in artichoke hearts for a Mediterranean-style twist.
- Add diced cucumber for extra crunch and freshness.
- Stir in a spoonful of mayo or Greek yogurt if you want to create a creamy Italian pasta salad variation.
Flexible dietary swaps.
One of the reasons I love pasta salad with zesty Italian dressing is how easy it is to adjust depending on dietary needs.
- Gluten-free: The cauliflower version is naturally gluten-free. If you use pasta, choose a gluten-free one.
- Classic pasta salad: Swap the cauliflower for 4 cups of cooked bowtie pasta and use the full cup of dressing.
- Vegetarian: Skip the pepperoni or replace it with marinated artichokes or roasted chickpeas.
- Dairy-free: Replace mozzarella with a dairy-free mozzarella alternative or simply leave the cheese out.
How to make Italian dressing pasta salad.
Putting together this salad is simple and comes together quickly once the ingredients are ready.
- Steam the cauliflower until crisp-tender (or cook the pasta according to package directions), then drain and rinse with cold water to cool it completely.
- In a large bowl, combine the cauliflower or pasta with tomatoes, mozzarella, olives, pepperoni, and diced bell pepper.
- Toss everything with zesty Italian dressing and chopped basil. Cover and refrigerate for at least two hours so the flavors blend.

How to serve it.
When zesty Italian pasta salad hits the table, it fits right in with just about any meal - from casual cookouts to simple weeknight dinners.
- Serve alongside grilled chicken, steak, pork, or baked fish for an easy dinner.
- Pair it with burgers or sandwiches at a cookout.
- Add it to a spread of Italian salads for parties and gatherings.
- Pack it for picnics or meal prep lunches.
- Garnish with extra chopped basil or freshly cracked black pepper before serving.
Kori's tips.
- Chill before serving. This classic pasta salad tastes best after at least two hours in the fridge so the flavors can mingle.
- Add more dressing if needed. Pasta can absorb dressing while chilling, so adding a little extra before serving keeps it fresh and flavorful.
- Fresh basil makes a difference. It adds a bright finish that really brings the salad to life.
FAQs
Store the salad in an airtight container in the refrigerator for up to 3 to 4 days. Give it a quick toss before serving and add a little extra dressing if needed.
Yes. This cold pasta salad with Italian dressing actually tastes even better after it chills for a few hours because the flavors have time to blend.
A bright, tangy Italian salad dressing recipe works best here. Homemade zesty Italian dressing gives the most flavor, but a good store-bought version works too.

This looks like a delicious make ahead lunch for the week. Will it last in the fridge if all put together and dressed?
Kori
I recently made it with dressing and all and ate on it for 2 days. I made the cauliflower version so it doesn't absorb excess liquid like the pasta version but I enjoyed it for my lunches! 🙂
