Ingredient Notes and Substitutions
This balsamic pasta salad is made with simple ingredients that come together beautifully. You can easily swap out some ingredients based on your preferences or what you have on hand.
For the Balsamic Vinaigrette
- Dijon mustard – Adding Dijon mustard to your dressing will help it mix better and give it a delicious taste. This will make it more flavorful and easier to eat.
- Seasoning – I used garlic and Italian seasoning. You could use different seasonings like oregano or basil depending on your preference. Feel free to make it your own!
- Balsamic vinegar – gives the salad a great sweetness and acidity.
- Olive oil – this recipe recommends using good, extra virgin olive oil. Olive oil helps bring the vinaigrette together. Don’t substitute this.
For the Pasta Salad
- Pasta – In this recipe, I am using fusilli. But you can also use other short shapes if you want like penne or other pasta noodles.
- Vegetables – I am using a mix of my favorite vegetables (peas, corn, tomatoes, bell pepper, cucumber, and black olives). But you can use other vegetables if you want. You can also use small broccoli florets, sliced snap peas, sliced celery, grape tomatoes, and diced carrots.

- Cheesy addition: Sprinkle in feta, mozzarella pearls, or parmesan for a cheesy twist.

Vegetable Rotini Pasta Recipe FAQs
The main difference between rotini and fusilli is the shape. Rotini is a spiral-shaped pasta, while fusilli is a corkscrew-shaped. They both have lots of surface area for the dressing to cling to, making them perfect for pasta salad with zesty Italian dressing.
No, they are not the same. But they are similar. Balsamic vinaigrette is made with balsamic vinegar, olive oil, and other seasonings like garlic and Italian seasoning. Italian dressing is usually made with white vinegar, oil, herbs, and spices.
I would not recommend adding the dressing ahead of time. The pasta will absorb the dressing, and it might get soggy.
If you want to prep it as a make-ahead balsamic salad, cook the pasta and chop the vegetables. Then prepare the dressing. Store everything separately in the fridge until you are ready. Then, just before serving, mix everything and add the Italian balsamic dressing.
If you want to keep it from sticking together, rinse it with cold water after cooking. This will stop the cooking process and help remove any excess starch from the pasta. Adding a little oil to the water can help to keep it from sticking.
This is a great side dish for any type of grilled meat. It is also good on its own as a light lunch or dinner.
If you have leftovers, store it in an airtight container in the fridge for up to three days.
