Creamy Cold Italian Pasta Salad
Ingredients
For the Creamy Italian Dressing:
- 1 cup mayonnaise high-quality store-bought or homemade
- 2 teaspoons Dijon mustard
- 4 garlic cloves minced
- 1 teaspoon red pepper flakes
- 3 teaspoons Italian seasoning
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- 3 tablespoons freshly squeezed lemon juice about 1½ lemons
- 3 tablespoons white wine vinegar
For the Pasta Salad:
- 12 ounces rotini or fusilli pasta tri-color works great!
- 1 cup red bell pepper diced small
- ½ cup shallot finely diced
- ½ cup black olives sliced
- 1 cup uncured salami diced
- 1 cup mozzarella cheese diced into small cubes
- ¼ cup fresh parsley finely chopped
- ½ cup fresh basil leaves thinly sliced
- Optional: Extra kosher salt and black pepper for serving
Instructions
- Whip Up the Dressing: In a blender or using an immersion blender with a wide-mouth jar, combine the mayonnaise, Dijon mustard, minced garlic, red pepper flakes, Italian seasoning, kosher salt, black pepper, lemon juice, and white wine vinegar. Blend on medium-high speed for 30-45 seconds until the dressing is smooth, creamy, and pale in color. Set aside.
- Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente (usually 8-10 minutes). Drain the pasta and rinse thoroughly under cold running water to stop the cooking and cool it down. Shake off excess water.
- Assemble the Salad: Transfer the cooled pasta to a large mixing bowl. Add the bell pepper, shallot, olives, salami, mozzarella, parsley, and basil. Pour the prepared dressing over everything.
- Toss and Coat: Use a large spoon to toss the ingredients until the pasta is glossy and evenly coated in the dressing. Taste and add a pinch more salt if needed.
- Chill & Serve: Cover the bowl and refrigerate for at least 1-2 hours to allow the flavors to meld. Before serving, give it a good stir. If the pasta has absorbed too much sauce, refresh it with a tiny splash of olive oil or extra dressing.
Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
- Make-Ahead: This salad tastes even better the next day, making it perfect for meal prep!
- Variation: Swap the salami for chickpeas for a vegetarian version, or use gluten-free pasta if needed.

Ingredients
To achieve the perfect balance of creamy and zippy, you’ll need these specific ingredients. Here is what you need to gather to make this creamy Italian pasta salad recipe:
- 1 cup mayonnaise (Opt for high-quality store-bought or homemade if you’re feeling adventurous)
- 2 teaspoons Dijon mustard
- 4 garlic cloves, minced
- 1 teaspoon red pepper flakes (Adjust this if you prefer less heat)
- 3 teaspoons Italian seasoning
- 1 teaspoon kosher salt, plus more to taste
- ½ teaspoon freshly ground black pepper, plus extra for serving
- 3 tablespoons freshly squeezed lemon juice (about 1 1/2 lemons, scrubbed well)
- 3 tablespoons white wine vinegar
- 12 ounces rotini or fusilli pasta (I love using tri-color for that classic look)
- 1 cup red bell pepper, diced small

- ½ cup black olives, sliced
- 1 cup uncured salami, diced
- 1 cup mozzarella cheese, diced into small cubes

Instructions
Here are the steps to bringing this masterpiece together. Don’t worry, it is incredibly straightforward!
1. Whip Up the Dressing
First, let’s tackle the liquid gold. In a blender or using an immersion blender with a wide-mouth jar, add the mayonnaise, Dijon mustard, minced garlic, red pepper flakes, Italian seasoning, kosher salt, black pepper, freshly squeezed lemon juice, and white wine vinegar. Blend this on medium-high speed for about 30-45 seconds. You want to see the texture transform until the dressing is completely smooth, creamy, and all ingredients are fully incorporated. The result should be a pale, creamy color with visible flecks of herbs and spices throughout. It looks absolutely glossy and smells divine! Set this aside while you handle the pasta.
2. Cook and Cool the Pasta
Bring a large pot of salted water to a rolling boil and add your rotini or fusilli. Cook it according to the package directions until it is al dente, which usually takes about 8-10 minutes. I recommend checking it a minute early; you want the pasta to have a slight bite to it since it will continue to absorb the dressing as it sits. Once cooked, drain the pasta in a colander and rinse it thoroughly under cold running water. This step is crucial because it stops the cooking process immediately and cools the noodles completely, preventing them from melting your cheese cubes later. Shake off the excess water and transfer it to a large mixing bowl.
3. Assemble the Salad

Now for the fun part! To the bowl with your cooled pasta, add the diced red bell pepper, finely diced shallot, sliced black olives, diced salami, cubed mozzarella cheese, chopped fresh parsley, and thinly sliced basil leaves. Pour that zippy, prepared Creamy Cold Italian Pasta Salad dressing over all the ingredients. Using a large spoon or spatula, toss everything together thoroughly. Ensure that every piece of pasta and all the delicious add-ins are well-coated with the creamy dressing. The pasta should look glossy and evenly dressed. Go ahead and taste a noodle; add additional kosher salt if needed. However, remember that the salami and olives add a nice salty punch on their own.

4. Chill to Perfection
Cover the bowl tightly with plastic wrap or transfer your Italian pasta salad with mayo to an airtight container. Refrigerate for at least 1 to 2 hours before serving. This patience pays off because it allows the flavors to develop and meld together beautifully. Before serving, please give it a good stir and check the consistency. If the pasta has absorbed too much dressing, you can refresh it by adding an extra drizzle of dressing or a splash of olive oil. Serve it chilled, garnished with extra-fresh basil, a dash of black pepper, and perhaps a sprinkle of grated Parmesan cheese if you are feeling fancy.

Tips, Variations & Serving Suggestions
I’ve made this salad a dozen different ways, and while the classic version is my favorite, you have plenty of cold pasta salad ideas to play with. Here are some tips to help you make it your own:
- Make it Meatless: For a vegetarian version, substitute with marinated artichoke hearts or chickpeas for extra padding.
- Gluten-Free Option: You can absolutely make a gluten-free creamy Italian pasta salad by using your favorite chickpea or brown rice pasta. Just be sure to rinse it gently, as GF pasta can be a bit more fragile.
- Lighter Dressing: For a health-forward twist, try substituting half of the mayonnaise with Greek yogurt. It keeps the tang but lightens the load!
- Prep Ahead: This is one of those dishes that actually tastes better the next day. You can make this up to 2-3 days in advance, making it the ultimate meal-prep winner.
Storage & Leftovers
If you have leftovers (which is rare in my house!), They store wonderfully in the refrigerator for up to 3 days. Please keep in mind that this is a dairy-based dressing, so avoid leaving it out in the hot sun for too long during your picnic.
What to Serve With Creamy Cold Italian Pasta Salad
This dish is the ultimate sidekick for summer pasta salad ideas, but what should be the main event? Since the salad is rich and savory, I like to pair it with dishes that come straight from the grill.
- Grilled Chicken or Sausages: The cool, creamy pasta balances perfectly with the smoky char of grilled meats.
- Corn on the Cob: A classic summer duo! The sweet essence of the corn complements the tangy vinegar in the dressing.
- Caprese Skewers: If you are serving a full spread of Italian pasta salad with mozzarella, complement it with some appetizers that double down on the fresh tomato and basil theme.
These pairings turn a simple bowl of pasta into a full-blown feast that feels effortless.

Frequently Asked Questions
What are the five mistakes to avoid in pasta salad?
The biggest mistakes are overcooking the pasta (it becomes mushy), not rinsing the pasta (it becomes sticky), under-salting the water, and adding the dressing too soon. In contrast, the pasta is still hot (the oil separates) and is not allowed to chill long enough to marinate properly. Avoiding these ensures a texture that is silky, not gummy.
What to add to creamy Italian pasta salad?
My personal preference is the classic salami and mozzarella combo, but you can also add artichokes, sun-dried tomatoes, cucumbers for crunch, or even cubes of sharp provolone. Experimenting with creamy pasta salad, such as adding olives or roasted red peppers, adds a lovely depth of flavor.
What’s the secret to a flavorful pasta salad?
The secret is to over-season your dressing slightly. Cold food tends to mute flavors, so your dressing needs to be bold, zippy, and vibrant before it hits the pasta. Additionally, letting it rest in the fridge is non-negotiable for optimal flavor absorption.
Conclusion
This Creamy Cold Italian Pasta Salad is proof that you don’t need complicated techniques to create something totally delicious. It’s glossy, vibrant, and packs a punch of flavor in every bite. Whether you’re heading to a potluck or want a hassle-free dinner, this recipe has your back.
