Most pasta salads? Meh. They're cold, kind of tangy, and honestly…forgettable.
But this one? This one's different.

My Tri Color Rotini Pasta Salad is briny, cheesy, meaty, and bold-with Genoa salami, creamy mozzarella cubes, juicy tomatoes, and not one but two types of olives, all tossed in a homemade Italian dressing that clings to every curl of tri-color rotini. It's the side dish that disappears first at potlucks-and tastes even better the next day.

❤️ Why You'll Love This Pasta Salad
This isn't your typical soggy, veggie-loaded side dish. It's built for real flavor and texture:
🧀 Real mozzarella cubes - Not shreds or pearls. Blocks hold their shape and give every bite some creamy chew.
🥓 Savory Genoa salami - Salty, rich, and bold. Turns this into a dish with substance.
🫒 Double olive action - Black and green olives with pimentos = briny, layered flavor.
🌈 Tri-color rotini - Not just pretty-it grips onto all that tangy Italian dressing.
It's basically an antipasto platter in pasta salad form-and we're not mad about it.
👩🍳 Why I Make This One Again and Again
I've made some version of this pasta salad for years-tweaking it every time.
At first, I used bottled dressing and shredded cheese, but it always fell flat. The flavor didn't soak in, and the cheese got lost in the mix. After tons of trial runs, I landed on this version: diced mozzarella from a block (for the best texture), homemade Italian dressing (zippy and bold), and tri-color rotini (grabs all that dressing).
It's the one I bring to BBQs, the one I meal prep on Sundays-and the one people always ask me to bring again.
🛒 Ingredient Notes
(See the recipe card below for full amounts.)

Here's why a few of these ingredients matter:
- Genoa Salami - Adds savory richness. Use a deli cut and slice into small cubes.
- Mozzarella Block (Diced) - Holds its shape and delivers a better bite than shreds or pearls.
- Black + Green Olives - Briny, bold flavor combo you won't get from just one type.
- Tri-Color Rotini - The ridges trap all that tangy dressing, and the colors pop on the plate.
💡 Pro Tip: Always chill the salad before serving to let the flavors meld.
🍽️ How to Make Tri Color Rotini Pasta Salad
Here's a quick overview. (See the recipe card below for full step-by-step instructions.)
Cook the pasta - Boil until al dente in well-salted water.
💡 Pro Tip: Rinse with cold water to stop cooking.
Make the dressing - Whisk together olive oil, red wine vinegar, Dijon, garlic, parmesan, and seasonings.

Toss warm pasta with a bit of dressing - While still warm, mix in a few tablespoons of the dressing. It soaks in better this way!
Prep the add-ins - Halve the tomatoes, dice the mozzarella and salami, and slice the onions and bell pepper.

Combine - Toss everything in a big bowl.

Dress The Pasta Salad – Pour the rest of the dressing over the pasta salad.

Chill – Cover and chill at least 1 hour before serving.

💡 Pro Tips for the Best Pasta Salad
✔️ Salt your water - It's your first layer of flavor.
✔️ Rinse that pasta - Stops cooking + keeps it from getting mushy.
✔️ Toss warm pasta with dressing - Helps it soak up flavor early.
✔️ Let it rest - Chill for at least 1 hour before serving.
✔️ Add extra dressing if making ahead - Pasta tends to absorb it over time.
✔️ Use mozzarella block - For the best texture and flavor.
🔄 Variations & Swaps
Want to make it your own? Try these:
- 🥒 Add cucumbers for extra crunch.
- 🌶️ Toss in banana peppers or artichokes for tang.
- 🍕 Swap salami for pepperoni or prosciutto.
- 🌈 Use red, orange, or yellow bell peppers for more color.
- 🌿 Add fresh basil or a sprinkle of parmesan before serving.
🧊 Storage & Make Ahead
- Fridge: Store in an airtight container for up to 3 days.
- Make Ahead: Best when made the night before. Add a splash of dressing before serving if needed.

❓ FAQ
Yes, but homemade makes a huge difference-and only takes 5 minutes.
Sure! Penne, fusilli, or farfalle all work-just choose a shape with grooves because it helps the dressing stay on the pasta.
Both! It's hearty enough for lunch or dinner, especially with extra salami or cheese.
