Grilled Zucchini Caprese Salad hits all the summer notes: smoky, juicy, herby, and just cheesy enough to keep everyone at the table happy. It works perfectly for busy weeknights or casual cookouts, since you pull it together in about 25–30 minutes start to finish. I make some version of this at least twice a week in July, usually while pretending my tiny patio grill counts as an outdoor kitchen.

Why Grilled Zucchini Caprese Salad Is Worth It

You get all the classic Caprese flavors—tomato, basil, mozzarella, and balsamic—but the grilled zucchini adds char, sweetness, and a little drama. The warm zucchini softens the mozzarella just enough, so every bite tastes creamy, smoky, and bright from the vinegar and fresh herbs.

This salad works as a side dish, light main, or meal prep base with extra protein on top. It also rescues that mountain of garden zucchini that shows up every summer and stares at you from the counter.

“This Grilled Zucchini Caprese Salad tastes like a fancy restaurant side dish, but I threw it together in under 30 minutes and everyone asked for seconds. ★★★★★”

Ingredients You Need

Zucchini and veggies

3–4 medium zucchini, sliced lengthwise into ¼-inch planks
1 pint cherry or grape tomatoes, halved (use mixed colors if you want extra visual points)
1 small red onion, very thinly sliced (or use shallots for a milder bite)

Cheese and herbs

8 oz fresh mozzarella, sliced or torn into bite-size pieces (use ciliegine or pearls if you want zero slicing)
½ cup fresh basil leaves, torn
1–2 tbsp fresh oregano or parsley, chopped (optional but tasty)

Olive oil and seasoning

3–4 tbsp extra-virgin olive oil, divided (use your good-tasting bottle here)
1–1½ tsp kosher salt, plus more to taste
½ tsp freshly ground black pepper
½ tsp garlic powder (or 1 small fresh garlic clove, grated)
¼–½ tsp red pepper flakes (optional, for a little kick)

Balsamic situation

2–3 tbsp balsamic vinegar
1–2 tbsp balsamic glaze (store-bought works great and saves time)
½ tsp honey or maple syrup (optional, helps balance acidity if your vinegar tastes sharp)

Substitution notes

Swap zucchini with yellow squash or a mix of both if that’s what you have.
Use marinated mozzarella balls from the deli section if you want built-in flavor.
Choose lactose-free mozzarella for sensitive eaters.
Use a good gluten-free balsamic glaze if you avoid gluten; some cheaper brands add thickeners.

Equipment

Outdoor grill, grill pan, or cast-iron skillet
Tongs
Large mixing bowl
Small jar or bowl for the dressing
Cutting board and sharp knife

Quick Tips & substitutions

Pat zucchini dry before grilling so it chars instead of steaming.
Brush zucchini lightly with oil; heavy oil drips and flares up.
Salt zucchini right before grilling so it does not release too much water.
Use a grill basket if your tomatoes feel small and roll everywhere.
Swap mozzarella with burrata for extra creaminess, but add it at the end so it stays intact.
Use vegan mozzarella and skip the honey for a fully vegan version.
Replace basil with baby arugula if you run out of herbs; toss it in right before serving.
Use leftover grilled zucchini from another meal and build the salad cold to save time.

How to Make Grilled Zucchini Caprese Salad

Prep the zucchini and veggies

Slice the zucchini lengthwise into ¼-inch planks so they do not fall through the grill grates. Lay them on a tray, drizzle with 1–2 tablespoons of olive oil, and season with salt, pepper, and garlic powder. Toss gently so every piece gets a light coat.

Halve the cherry tomatoes and slice the red onion as thin as you can. Add tomatoes and onion to a large bowl and set them aside. Tear or slice the mozzarella and keep it chilled until you finish grilling.

Mix the balsamic dressing

In a small jar or bowl, combine balsamic vinegar, 2 tablespoons olive oil, a pinch of salt, pepper, red pepper flakes, and honey or maple syrup if you use it. Whisk or shake until the dressing looks glossy and thickened. Taste and adjust salt or sweetness so it hits that sweet-tangy balance you like.

Grill the zucchini

Heat your grill or grill pan over medium-high heat until it feels hot when you hold your hand a few inches above it. Lay the zucchini planks across the grates in a single layer. Grill each side for about 3–4 minutes, until you see nice grill marks and the zucchini feels tender but not mushy.

Move cooked zucchini to a cutting board and let it cool for a couple of minutes. Slice the planks into thick half-moons or strips so they mix easily into the salad. Work in batches if your grill space runs small.

Build the salad

Add the warm zucchini pieces to the bowl with tomatoes and onion. Pour about two-thirds of the balsamic dressing over the veggies and toss gently so you keep the zucchini intact. Add the mozzarella, torn basil, and any extra herbs, then toss again very lightly.

Drizzle balsamic glaze over the top and add the rest of the dressing if the salad looks dry. Taste and adjust salt, pepper, or red pepper flakes. Serve slightly warm or at room temperature for the best flavor.

Recipe Variations

Gluten-free
- Use a gluten-free balsamic glaze and double-check spice blends.
- Serve over gluten-free pasta or quinoa for a heartier bowl.
Vegan
- Swap mozzarella with a good vegan mozzarella or marinated tofu cubes.
- Add toasted pine nuts or walnuts for extra richness.
Low carb / keto-ish
- Skip any sweetener in the dressing and use only balsamic vinegar and oil.
- Add grilled chicken, shrimp, or salmon on top for more protein.
Extra add-ins
- Toss in grilled corn kernels for sweetness and crunch.
- Add olives or artichoke hearts for a briny hit.
- Sprinkle with toasted breadcrumbs or croutons right before serving for texture.

Ways to Serve Grilled Zucchini Caprese Salad

Serve as a side dish with grilled chicken, turkey burgers, or simple baked fish.
Spoon over toasted sourdough or ciabatta as a chunky bruschetta-style topping.
Pile on top of cooked farro, couscous, or orzo for a hearty grain bowl.
Pack it as a picnic salad and serve at room temperature.
Use leftovers as a topping for flatbread with a little extra mozzarella.

Storage Success

Store leftover Grilled Zucchini Caprese Salad in an airtight container in the fridge for up to 3 days. The zucchini and tomatoes release some juices, so the salad turns more marinated and saucy on day two. Stir it before serving and add a small splash of olive oil or balsamic if it tastes muted. I like to eat leftovers cold or at room temperature and sometimes tuck them into a warm pita with extra greens.
