Italian Vegetarian Pasta Salad

The farmers market on Saturday mornings has become something of a ritual, and last weekend a basket of impossibly red cherry tomatoes practically jumped into my hands.

I brought a massive bowl of this to a friends rooftop potluck last summer and watched three people ask for the recipe before the sun even set.

Ingredients

• Short pasta (400 g): Fusilli is my go to because those little spirals catch the dressing in every fold, but penne and farfalle work beautifully too.
• Cherry tomatoes (1 cup, halved): Use the ripest ones you can find because they are the backbone of sweetness in this salad.
• Cucumber (1 small, diced): English cucumbers with fewer seeds give the best crunch without watering everything down.
• Red and yellow bell peppers (1 each, diced): The color combination is not just pretty, the slight flavor difference between them adds real depth.
• Red onion (1/2 small, finely sliced): Soak the slices in cold water for five minutes if you find raw onion too aggressive.
• Kalamata olives (1/2 cup, pitted and halved): Do not skip these because that salty brine pulls every other flavor together.
• Sun-dried tomatoes (1/4 cup, sliced): They deliver an intense umami hit that fresh tomatoes alone cannot achieve.
• Fresh basil leaves (1/3 cup, torn): Tear them by hand rather than cutting with a knife to keep the edges from blackening.
• Mozzarella balls (150 g, halved): Bocconcini sized pearls are ideal since they distribute creaminess evenly through every bite.
• Grated Parmesan (1/3 cup, optional): A shower of this right before serving adds a savory finish that people always notice.
• Extra virgin olive oil (1/3 cup): This is the dressing base so use the best bottle you have, you will absolutely taste the difference.
• Red wine vinegar (2 tbsp): It provides the right sharpness without overpowering the vegetables.
• Garlic (1 clove, minced): One clove is enough because raw garlic can quickly take over a cold dish.
• Dijon mustard (1 tsp): This acts as the emulsifier that keeps your dressing from separating.
• Dried oregano (1/2 tsp): A classic Italian note that grounds the whole salad in familiar territory.
• Salt and pepper: Season gradually and taste as you go because the olives and cheese already contribute salt.

Instructions

Boil the pasta to perfection:

Cook your short pasta in well salted boiling water until just al dente, then drain immediately and rinse under cold running water until completely cool to the touch.

Build the vegetable base:

In your largest mixing bowl, toss together the halved cherry tomatoes, diced cucumber, both colors of bell pepper, sliced red onion, halved olives, sun-dried tomatoes, and torn basil leaves.

Unite pasta and vegetables:

Add the cooled pasta to the bowl of vegetables and give everything a gentle toss so the ingredients start getting acquainted.

Whisk the dressing:

In a small bowl, combine the olive oil, red wine vinegar, minced garlic, Dijon mustard, dried oregano, a pinch of salt, and a generous crack of black pepper, then whisk vigorously until the mixture looks creamy and unified.

Dress the salad:

Pour the dressing over the pasta and vegetables, then toss with confidence making sure every spiral and crevice gets coated.

Add the cheese:

Gently fold in the halved bocconcini and Parmesan if using, taking care not to mash the soft mozzarella as you mix.

Rest and adjust:

Taste a forkful, adjust salt and pepper as needed, then refrigerate for at least fifteen minutes so the flavors settle into something greater than their parts.

Serve with flair:

Bring the salad out cold or let it sit at room temperature for ten minutes, then scatter a few extra basil leaves on top before presenting it to the table.

Save

There is something quietly wonderful about a dish that does not require an oven, a timer, or any real precision, just good ingredients and a little patience while the flavors marry in the fridge.

Making It Your Own

This recipe is endlessly flexible once you understand the formula: sturdy pasta, colorful vegetables with contrasting textures, something briny, something creamy, and a bold vinaigrette to tie it all together.

What to Serve Alongside

A chilled glass of Pinot Grigio turns this salad into a proper summer meal, though sparkling water with a fat wedge of lemon is equally refreshing for a weekday lunch.

Storing and Transporting

This salad travels exceptionally well which makes it a reliable choice for picnics and potlucks, though a few practical habits will keep it at its best.

• Store leftovers in an airtight container in the fridge for up to three days, knowing the pasta will absorb more dressing each day.
• Add a splash of olive oil and a squeeze of lemon before serving leftovers to wake everything back up.
• Always toss again right before serving since the ingredients settle during chilling.

Save

Keep this recipe close because once people taste it, they will ask for it again and again, and you will be grateful it is this easy.

Recipe FAQs

→ Can I make this pasta salad ahead of time?

Absolutely. In fact, making it a few hours ahead allows the flavors to meld together beautifully. Just cover and refrigerate, then give it a gentle toss before serving. Add the fresh basil leaves right before serving so they stay vibrant.

→ What type of pasta works best for this salad?

Short pasta shapes like fusilli, penne, farfalle, or rotini are ideal because they hold the dressing well and mix evenly with the vegetables. Their ridges and curves catch every bit of the vinaigrette, ensuring great flavor in every bite.

→ How long does this pasta salad keep in the refrigerator?

Stored in an airtight container, this pasta salad stays fresh for up to 3 to 4 days in the refrigerator. The flavors actually deepen overnight, making leftovers even more delicious. Give it a quick stir before serving.

→ Can I substitute the mozzarella with a dairy-free alternative?

Yes, you can swap the bocconcini and Parmesan for plant-based mozzarella-style cheese or simply omit them entirely. Adding marinated tofu cubes or white beans is another great way to maintain protein content without dairy.

→ What can I add to make this pasta salad more filling?

Consider tossing in chickpeas, grilled vegetables like zucchini and eggplant, roasted artichoke hearts, or even sliced avocado. A handful of toasted pine nuts or sunflower seeds also adds satisfying crunch and substance.

→ Should I serve this pasta salad cold or at room temperature?

Either works well. Chilling it for at least 15 minutes before serving lets the flavors develop fully, but bringing it to room temperature for about 20 minutes before eating softens the dressing and enhances the taste of the vegetables and cheese.
