Recipe Ingredients

Find the full printable recipe with specific measurements below.

  • Rotini pasta: This is my favorite pasta to use, as the dressing adheres it to so nicely and the tri-color is pretty.
  • Bell peppers: Red and green add a nice bit of spice to the salad.
  • Red onion: Italian dressing and red onions are a match made in heaven.
  • Cherry tomatoes: These add such a nice burst of sweetness to the salad.
  • Black olives: These are a great way to punch up the flavor.
  • Mozzarella: The small mozzarella balls are a perfect size for the pasta.
  • Italian dressing: I love to use this recipe, but store-bought works as well.
  • Fresh herbs: Parsley or basil are my picks to go with the rest of the ingredients.

Tips for the Perfect Pasta Salad

  • Salt the water. A trick when boiling the pasta is to salt the water first. It helps improve the flavor of the noodles, as well as helps the water boil slightly faster.
  • Cook al dente. The goal is to cook the noodles al dente, so that they’re tender to bite but will still remain sturdy enough to hold up in the salad. If you over cook the noodles, they can get mushy and fall apart easily when tossing.
  • Extras. There are plenty of delicious extras that you can add to this recipe. Mix in some pepperoni or chopped salami, sliced cucumbers, chickpeas or add a sprinkling of fresh parmesan cheese. You can even swap feta for mozzarella, or leave the cheese out entirely to make this a vegan dish.
  • Let marinate. Whenever I make this dish, I like to let it chill in the fridge for a few hours before serving. This gives the dressing some time to marinate together with the pasta and veggies, so that it’s extra flavorful and delicious. Plus you can’t beat a cold pasta salad in the summer!

Recipe FAQs

Can I double the recipe for East Pasta Salad with Italian Dressing?

Absolutely! Just be sure to use a big enough bowl when stirring everything together.

Do I have to use rotini pasta?

Traditionally this dish is made with rotini noodles. They have the perfect shape and ridges to really soak in the flavor from the Italian dressing. That doesn’t mean you can’t use other varieties of noodles though. Penne, fusilli or bow-tie pasta would all work great, too.

Make Ahead + Storing

You can definitely make this recipe the night beforehand if you prefer. The longer it marinates in the fridge, the more flavor it will have. I love to make it ahead of time and then when ready to serve, I’ll add fresh chopped parsley and a sprinkle of parmesan cheese. Delicious!

If you have leftovers, they will stay fresh in the fridge for about 5 days. They are perfect to enjoy throughout the week and make an amazing side dish for so many lunches or dinners.
