Juicy Pasta Salad with Mozzarella Balls

Growing up, pasta salad was always our go-to for summer picnics and backyard gatherings. These days, I still find myself reaching for this classic dish whenever friends drop by or when I need something easy to bring to a potluck. This version with fresh mozzarella balls has become my family’s favorite – it’s simple, satisfying, and always disappears first at parties.

I particularly love making this pasta salad because I can prep everything ahead of time. The flavors actually get better when they have time to mingle in the fridge overnight. Plus, it’s one of those forgiving recipes where you can toss in whatever vegetables you have on hand. My kids help by cutting the mozzarella balls in half (and sneaking a few while they work), making it a fun kitchen activity for everyone.

Whether you’re looking for an easy lunch option or need a reliable side dish for your next gathering, this pasta salad has got you covered. Best of all? No stove-watching required once the pasta’s cooked.

What Kind of Mozzarella Should I Use?

For pasta salad, those little mozzarella balls (also called ciliegine or bocconcini) are perfect since they’re already bite-sized and match well with cherry tomatoes. You’ll find them packed in water or brine at most grocery stores, usually near the specialty cheese section. If you can only find larger fresh mozzarella balls, just cut them into smaller, bite-sized pieces – they’ll taste just as good. Just make sure to use fresh mozzarella rather than the firm, aged type you’d use for pizza, as fresh mozzarella has the right texture and mild, creamy flavor that works best in cold pasta salads.

Options for Substitutions

This pasta salad is pretty flexible and you can switch things up based on what you have in your kitchen:

• Whole wheat pasta: Regular pasta works perfectly fine here – any short shape like rotini, fusilli, or bow ties will do. You can even try gluten-free pasta if you need to, just be sure not to overcook it.
• Balsamic vinegar: Red wine vinegar makes a good substitute, though the flavor will be less sweet. If using red wine vinegar, you might want to add an extra teaspoon of honey to balance the taste.
• Mozzarella balls: If you can’t find mozzarella balls, cut up a block of fresh mozzarella into bite-sized pieces. In a pinch, cubed regular mozzarella will work too, though the texture will be firmer.
• Fresh basil: While fresh basil gives the best flavor and I really recommend using it, you can use about 2 tablespoons of dried basil if needed. Or try fresh spinach with a bit of dried oregano for a different twist.
• Cherry tomatoes: Any small tomato variety works great – grape tomatoes, sun-dried tomatoes, or even regular tomatoes cut into chunks will do the job.
• Dijon mustard: Regular yellow mustard or whole grain mustard can work too. If you’re out of mustard completely, try adding a splash more vinegar and a pinch of garlic powder.

Watch Out for These Mistakes While Cooking

The biggest mistake when making pasta salad is overcooking the pasta – always cook it just until al dente, as it will continue to absorb dressing and soften as it sits in the refrigerator. A common error is adding the dressing to hot pasta, which causes the noodles to become mushy and absorb too much liquid – instead, rinse the pasta in cold water to stop the cooking process and allow it to cool completely before mixing with other ingredients. To keep your mozzarella balls from becoming rubbery, add them just before serving, and remember to pat them dry first to prevent excess liquid from diluting your dressing. For the freshest flavor, wait to add the basil until right before serving, as it can quickly turn dark and wilted when mixed with dressing too far in advance. Lastly, always taste and adjust your seasoning just before serving, as cold temperatures can dull flavors, requiring an extra pinch of salt or splash of vinegar to make the flavors pop.

What to Serve With Pasta Salad?

This fresh and filling pasta salad works great as a side dish, but you can easily turn it into a complete meal with a few simple additions. I love serving it alongside some grilled chicken or Italian-style sausages for a perfect summer dinner. For a lighter option, pair it with a simple green salad dressed with lemon vinaigrette – the bright citrus flavors complement the balsamic dressing in the pasta salad really well. If you’re bringing this to a BBQ or picnic, it goes great with burgers, pulled pork sandwiches, or grilled vegetables, and you can even serve it at room temperature which makes it super convenient.

Storage Instructions

Keep Fresh: This pasta salad is perfect for making ahead! Pop it in an airtight container in the fridge, where it’ll stay good for up to 5 days. The flavors actually get better as they mingle together, making it taste even yummier the next day.

Make Ahead Tips: If you’re planning to make this ahead for a party or gathering, I recommend adding the fresh basil just before serving to keep it looking fresh and green. You might also want to save a bit of the dressing to toss with the salad right before serving, as the pasta tends to soak up the dressing over time.

Serve Later: When you’re ready to serve your stored pasta salad, take it out of the fridge about 30 minutes before eating to let it come to room temperature – this helps bring out all the flavors. Give it a quick toss, and if it seems a bit dry, drizzle with a little extra olive oil to freshen it up.

Ingredients

For the vinaigrette:

• 1/2 cup extra virgin olive oil
• 1 tbsp dijon mustard (I prefer Maille Dijon Originale)
• 1 large garlic clove (minced)
• 1/2 tsp fine sea salt
• 1/4 cup balsamic vinegar
• 1/2 tsp ground black pepper (freshly ground for best flavor)
• 1 tbsp honey

For the pasta salad:

• 1 lb whole wheat pasta
• 1 pint cherry tomatoes (halved)
• 1/2 cup red onion (thinly sliced)
• 12 oz mozzarella balls (small, drained)
• 2 oz fresh basil (roughly chopped)

Step 1: Prepare the Vinaigrette

Start by preparing the vinaigrette.

In a mixing bowl, combine balsamic vinegar, honey, mustard, and minced garlic.

Season with a pinch of salt and a dash of pepper.

Add oil to the bowl, and using a fork or a whisk, stir the mixture vigorously for a few seconds until it emulsifies and comes together.

Place the vinaigrette in the refrigerator for at least 10 minutes to allow the flavors to meld together perfectly.

Step 2: Cook the Pasta and Prepare the Vegetables

While the vinaigrette is resting, cook your pasta according to the package directions.

Meanwhile, cut the tomatoes in half and thinly slice the basil and onion.

Once the pasta is cooked to your liking, drain well in a colander and run it under cold water to stop the cooking process and cool the pasta quickly.

Step 3: Assemble the Salad

In a large serving bowl, combine the cooled pasta with the chopped tomatoes, basil, and onion.

Pour the chilled vinaigrette dressing over the pasta and add mozzarella balls.

Using a wooden spoon, mix everything well until the pasta and veggies are fully coated with the delicious dressing.

Step 4: Chill and Serve

For the best flavor, refrigerate the prepared pasta salad for at least 20 minutes before serving.

However, if you’re in a hurry, you may serve it immediately.

Enjoy your refreshing and flavorful pasta salad!
