Tomato Plum Mozzarella Herb Salad
This Tomato Plum Mozzarella Herb Salad is the recipe that made me fall in love with late summer all over again. Juicy heirloom tomatoes, sweet ripe plums, and pillowy fresh mozzarella come together in a way that feels almost too beautiful to eat.
I first threw this together for a Labor Day potluck when the farmers market was bursting with stone fruit and every color of tomato imaginable. Seriously, people kept pulling out their phones to photograph it before anyone touched it.

Instructions
Make the balsamic herb vinaigrette. In a small bowl or jar, whisk together the olive oil, balsamic vinegar, Dijon mustard, honey, garlic, Italian seasoning, salt, and pepper.
Whisk until the dressing is smooth and fully emulsified — it should look like glossy, mahogany-colored silk. Set aside while you assemble the salad.
Arrange the base. Lay the tomato slices and plum wedges across a large serving platter or into a wide salad bowl. Alternate colors and shapes as you go for a stunning mosaic effect.
Tuck the mozzarella pearls or torn pieces between the fruit. The white cheese against the deep red and gold of the tomatoes and plums is genuinely eye-catching.
Add the red onion. Scatter the thinly sliced red onion over the top. In my testing, I found that soaking the slices in cold water for 10 minutes first keeps the flavor bright without the raw sharpness overpowering the fruit.
Finish with fresh herbs. Tear the basil leaves directly over the platter and sprinkle the parsley and chives on top. The herbs should look loose and generous — like a late summer garden just leaned over and dropped them there.
Dress and serve. Drizzle the balsamic herb vinaigrette evenly over the salad. Top with toasted pine nuts if using and a few bold grinds of black pepper.
Serve immediately, or chill for 10 to 15 minutes for a more refreshing, marinated version where the juices mingle into something almost like a light dressing of their own.
Substitutions & Variations
For a vegan tomato plum salad, simply skip the mozzarella or swap it for creamy vegan ricotta dolloped between the fruit. Replace the honey in the dressing with maple syrup and you’re all set.
No plums? This late summer salad works beautifully with ripe nectarines, white peaches, or even halved figs when they’re in season. The key is ripe, fragrant fruit that’s sweet enough to contrast the tangy balsamic.
To make it a high-protein mozzarella herb salad, add torn prosciutto, grilled chicken strips, or try it alongside our hot honey shrimp avocado salad for a full summer feast.
After making this dozens of times, my family’s favorite variation is swapping pine nuts for candied walnuts in the fall when plums give way to pears. The sweetness adds a whole new dimension.
Expert Tips & Troubleshooting
Watery salad pooling on the platter? Salt draws moisture from tomatoes fast. Wait to dress the salad until right before serving, or pat the tomato slices gently with a paper towel after cutting.
Plums too tart? In my testing, I found that a very ripe plum — one that gives slightly when pressed — makes all the difference. Underripe fruit can throw off the sweet-savory balance the whole salad depends on.
Dressing separating? The Dijon mustard acts as an emulsifier, but if it splits, just whisk again or give the jar a hard shake before drizzling. According to Bon Appetit’s guide to making vinaigrette, mustard and a slow drizzle of oil are the two keys to a dressing that holds together.
Storage & Meal Prep
| Component | Storage Method | Duration |
|---|---|---|
| Assembled salad (undressed) | Covered platter or airtight container, refrigerator | Up to 1 day |
| Balsamic herb vinaigrette | Sealed jar, refrigerator | Up to 1 week |
| Sliced plums and tomatoes (separate) | Airtight container, refrigerator | Up to 2 days |
This salad is best assembled fresh, but you can prep the dressing and slice the fruit and tomatoes several hours ahead. Keep everything separate and bring together just before serving for the cleanest presentation.
Leftover dressed salad is still delicious the next day — the balsamic soaks into the plums and tomatoes like a light marinade. Serve it alongside crusty bread to soak up all those gorgeous juices.
Serving Suggestions
This tomato plum salad is a natural alongside grilled fish, lamb chops, or a rustic cheese board. It’s elegant enough for a dinner party but relaxed enough for a weeknight patio meal.
For a full spread, pair it with our hearty lemon basil white bean rice salad for satisfying contrast, or round out a summer salad bar with our crowd-pleasing pickled onion garden ranch salad.
Tomato Plum Mozzarella Herb Salad FAQs
Can I make this tomato plum mozzarella herb salad ahead of time?
Yes — prep the components up to a few hours ahead and store them separately. Assemble and dress right before serving so the tomatoes and mozzarella stay fresh and the herbs don’t wilt.
What plums work best in this salad?
Ripe red or black plums give the best sweet-tart balance and jewel-toned color. Look for ones that give slightly when pressed. Nectarines or peaches make excellent swaps if plums aren’t available.
How do I keep fresh mozzarella from getting watery?
Pat fresh mozzarella dry with a paper towel before adding it to the platter. This prevents excess liquid from pooling and diluting your balsamic herb vinaigrette.
Why is my balsamic vinaigrette separating?
Dressings separate naturally — just re-whisk or shake the jar before drizzling. The Dijon mustard in this recipe helps it hold together longer than most simple vinaigrettes.
Can I use dried herbs instead of fresh in this mozzarella herb salad?
Fresh herbs are strongly recommended here since they are part of what makes this salad vibrant and aromatic. In a pinch, use half the amount of dried herbs, but the flavor will be less lively.
