Tomato Mozzarella Pasta Salad

Off the record, I call this one “poor man’s Caprese salad” because it’s based on Caprese salad, but with all the budget swaps I’ve made, I don’t think I can get away with calling that anymore. 😅 Regardless of what you call it, this Tomato Mozzarella Pasta Salad with homemade Parmesan Balsamic Vinaigrette is super light and refreshing, and just about the only thing I want to eat in this super hot 95+ degree weather. 🥵 You feel me?

This Tomato Mozzarella Pasta Salad will be a hit at any potluck, but also holds up really well in the refrigerator (undressed), making it a great meal prep or refrigerator salad for the week. Plus, there’s plenty of room for customization, so read on for some ideas for making this salad your own.

Dressing Options

I went with a creamy Parmesan Balsamic Vinaigrette for this salad, but you can change up this dressing a few ways to make it match your dietary needs. First, you can totally skip the Parmesan if you want to keep the salad vegetarian. If you can’t have or don’t want mayo, this dressing is also super awesome when you leave the mayo out, but I do like how the mayo mellows the flavors and makes it slightly creamy. And lastly, you can make things super easy on yourself and use a store bought balsamic vinaigrette or even Italian dressing, if that’s what you have on hand.

About That Mozzarella…

Fresh mozzarella is the best for this salad, but it can also be quite pricey. I was lucky enough to find a large 16 oz. log of fresh mozzarella today for a really good price (I’ll be freezing the other half), so I used that. But if you can’t find a good deal on fresh mozzarella, whole milk mozzarella in either block or stick form will also work. And yes, by “stick form” I mean cheese sticks. I’ve totally diced up mozzarella sticks to use in this salad before! Not elegant, but it worked with my budget! 

Vegetable Options

Grape tomatoes are cute, but if you can’t find them for a good price, feel free to dice a regular tomato in their place (you’ll want about 1.5 cups diced tomatoes). This is a great place to take advantage of fresh local tomatoes that will really give the salad a big flavor punch. Red onions also work well with these flavors if you have some to use up, as do bell peppers or cucumbers.

Prep Time: 10 mins
Cook Time: 15 mins
Total Time: 25 mins
Servings: 6 about 1.5 cups each

Ingredients

  • 8 oz. bowtie pasta ($0.67)
  • salt for pasta water ($0.02)
  • 3 cups fresh spinach ($1.20)
  • 1 pint grape tomatoes ($2.50)
  • 8 oz. mozzarella* ($2.60)

Parmesan Balsamic Vinaigrette

  • 1/3 cup olive oil ($0.55)
  • 3 Tbsp balsamic vinegar ($0.41)
  • 2 Tbsp mayonnaise ($0.17)
  • 2 Tbsp grated Parmesan ($0.22)
  • 1/2 Tbsp Dijon mustard ($0.09)
  • 1 clove garlic, minced ($0.08)
  • 1/2 tsp dried basil ($0.05)
  • 1/4 tsp salt ($0.01)
  • freshly cracked pepper ($0.02)

Instructions

  • Fill a pot with water and add two large pinches of salt. Cover the pot and bring it to a boil over high heat. Once boiling, add the pasta and continue to boil until the pasta is tender. Drain the pasta in a colander, give it a brief rinse with cool water, and let it drain well while you prepare the rest of the salad.
  • While waiting for the pasta to cook, prepare the rest of the salad. Start with the Parmesan Balsamic Vinaigrette. Combine all the dressing ingredients in a jar or blender. Either blend until combined or shake your jar until the ingredients are well combined. Set the dressing aside until needed.
  • Roughly chop the spinach and slice the grape tomatoes in half. Dice the mozzarella into 1/2-inch cubes.
  • Add the spinach, tomatoes, and mozzarella to a large bowl. Once the pasta is well drained and mostly cool, add it to the bowl with the mozzarella and vegetables. Make sure the pasta is no longer hot, so it doesn't wilt the spinach or melt the cheese.
  • Toss the ingredients to combine. If serving the salad later, store it like this without dressing. If serving immediately, add half of the dressing and toss to coat. Add more dressing as desired.

Notes

*Fresh mozzarella is best, but block or stick mozzarella can be used in its place. Whole milk mozzarella (not part-skim), if possible.

Step by Step Photos

Cooked bowtie pasta draining in a colander.

Begin by cooking 8 oz. bowtie pasta. You can prepare everything else for the salad in the time it takes the pasta to cook. Fill a pot with water, add two large pinches of salt, place a lid on top, and bring to a boil over high heat. Once boiling, add the pasta and continue to boil until the pasta is tender. Drain the pasta in a colander, rinse briefly with cool water, then let it drain very well.

Next, make the Parmesan Balsamic Vinaigrette. Add all of the ingredients for the dressing to either a blender or jar (1/3 cup olive oil, 3 Tbsp balsamic vinegar, 2 Tbsp mayonnaise, 2 Tbsp grated Parmesan, 1/2 Tbsp Dijon mustard, 1 clove of garlic (minced), 1/2 tsp dried basil, 1/4 tsp salt, and some freshly cracked pepper). Blend the ingredients until emulsified, or shake your jar until the ingredients are combined. 

Roughly chopped spinach

Roughly chop about 3 cups of fresh spinach.

Halved grape tomatoes

Slice one pint of grape tomatoes in half. 

Diced fresh mozzarella

Dice 8 oz. fresh mozzarella into 1/2-inch cubes. I froze the other half of the cheese (the part still in the wrapper on the left) for later.

Combine mozzarella and vegetables in a bowl

Add the spinach, tomatoes, and mozzarella to a large bowl.

Toss salad to combine ingredients

Once the pasta is well drained and mostly cool, add it to the bowl. Make sure the pasta is not hot so you don’t wilt the spinach or melt the cheese. Toss the salad to combine the ingredients. 

Store undressed salad for later in a resealable container

If you’re planning to eat the salad later, store it at this point, without dressing, in a resealable container. The salad will stay good this way for 3-4 days.

Or, if you plan to serve it now, add about half of the dressing and toss the salad again to coat it in the dressing. Add more dressing as desired.
