Ingredients You’ll Need for Cucumber Caprese Salad

Below I’ve broken the ingredients into what you really need, little extras that make it feel special, and smart swaps if your pantry changes. Everything here is naturally gluten-free.

Essentials

2 tablespoons olive oil — a good, cold-pressed extra-virgin olive oil gives the dressing a smooth, fruity base.
1 tablespoon balsamic vinegar — the touch that balances the oil with a gentle sweetness and tang.
1 tablespoon dried oregano — adds that warm, herb-y lift; dried is fine and easy to keep on hand.
1 tablespoon dried basil — brings the classic Caprese flavor without requiring fresh herbs every time.
Dash of salt — I use kosher or sea salt to taste.
Dash of freshly ground black pepper — or to your preference.
1 large cucumber — peeled and with the skin gently scraped with a fork before slicing thin and dicing. The scraping softens the texture and adds a pretty, rustic look.
1½ cups cherry tomatoes — washed and quartered; their natural sweetness keeps the salad lively.
8 oz fresh mozzarella — sliced into bite-sized pieces or use pearl (bocconcini) mozzarella if you prefer.
½ large red onion — thinly sliced and diced. If onion isn’t your thing, you can omit it.

All of these ingredients are naturally gluten-free and easy to source.

Optional Add-ons

These extras are optional but cozy and comforting — still gluten-free and family-friendly:

Fresh basil leaves — if you have fresh basil, chiffonade a few leaves for a brighter herbal note.
A squeeze of fresh lemon juice — adds lift and brightness in place of or alongside balsamic.
A sprinkle of flaky sea salt on top before serving — for a restaurant-like finish.
Toasted pine nuts — for a soft crunch (ensure nuts are processed in a gluten-free facility if you’re sensitive).
A few olives (like Castelvetrano or Kalamata) — chopped, for savory depth.
A drizzle of honey — just a tiny amount can mellow the balsamic if your tomatoes are a little tart.

Substitutions and Shortcuts

Life in the kitchen rarely follows the plan — here are calm, useful swaps that keep the recipe easy:

Mozzarella: If you don’t have fresh mozzarella, use small bocconcini or even a soft goat cheese for a tangier note. All are gluten-free.
Balsamic vinegar: Use red wine vinegar plus a pinch of honey if you prefer a lighter tang — both are gluten-free. (No alcohol in the final dish; the vinegar is a small pantry staple.)
Dried herbs: Swap equal amounts of Italian seasoning if that’s what’s on hand.
Fresh herbs: If you have fresh oregano or basil, use 1 tablespoon fresh of each instead of dried, or simply scatter a handful of basil leaves over the finished salad.
No red onion: Use a mild sweet onion or a few thin slices of scallion for a gentler bite.
Quick prep: Use pre-washed cherry tomatoes and pearl mozzarella if you want to assemble faster — I do this on busy weeknights.

All swaps here keep the salad fully gluten-free and approachable.

How to Make Cucumber Caprese Salad Step-by-Step

I like to think of this salad as a gentle recipe: each step is small and kind to the cook. Below I’ll walk you through clear, beginner-friendly steps so you can feel relaxed and confident.

Gather everything first.
- I always lay out my cucumber, tomatoes, mozzarella, onion, and the small bowl for the dressing. Having everything ready makes the process feel calm and keeps timing simple.
Make the dressing.
- In a small bowl, whisk together 2 tablespoons olive oil, 1 tablespoon balsamic vinegar, 1 tablespoon dried oregano, 1 tablespoon dried basil, and a dash of salt and pepper. Taste and adjust lightly — a little more balsamic for tang, or another pinch of salt if it feels gentle. Set this aside while you prepare the vegetables so the flavors can mingle.
Prepare the cucumber.
- Wash and peel your cucumber. I like to gently scrape the peeled cucumber skin with the back of a fork up and down a few times — this softens the outer texture and gives the cucumber a pretty, slightly ruffled look when sliced. Slice thin, then dice into bite-sized pieces. Add the cucumber to a medium-sized mixing bowl.
Add the cherry tomatoes.
- Quarter about 1½ cups of cherry tomatoes and add them to the bowl with the cucumbers. If your tomatoes are especially juicy, don’t worry — a little juice in the bowl helps dress everything.
Prep the onion (optional).
- Thinly slice and dice ½ of a large red onion. If you find raw onion too strong, rinse the sliced pieces briefly under cold water and pat dry — this softens the bite. Add the diced onion to the bowl with the vegetables. If you prefer no onion, simply skip this step.
Add the mozzarella.
- Slice 8 ounces of fresh mozzarella into bite-sized pieces, or add pearl mozzarella whole. Add the cheese to the bowl on top of the vegetables.
Dress the salad.
- Pour the prepared dressing evenly over the vegetables and mozzarella. Use a large spoon to gently toss everything together — be tender so the mozzarella keeps its shape and the tomatoes don’t get squashed.
Let it sit.
- Allow the salad to rest for about 10 minutes at room temperature. This short rest lets the flavors relax into each other — the herbs bloom, the balsamic softens, and the cucumber and tomato absorb just enough dressing to feel cohesive.
Final touch and serve.
- Taste the salad and add a gentle pinch more salt or a crack of black pepper if needed. If you’re using fresh basil or a sprinkle of flaky sea salt, add it right before serving to keep those textures bright.

A note on timing: this salad is forgiving. If it sits a little longer (up to 30 minutes), it will simply deepen in flavor. If you need to serve at a later time, keep it chilled and add a quick toss before serving.

Common Mistakes to Avoid

Mistakes are part of the way we learn in a warm kitchen — they’re welcome even when we’d rather not make them. Below are three common things I’ve seen and how to gently avoid them so your Cucumber Caprese Salad shines.

Mistake 1: Overly watery or dry textures

A common worry with cucumber salads is the texture — either watery and soggy or too dry and bland. To avoid this, choose firm cucumbers and slice them thin and even. Quartered cherry tomatoes add sweetness without releasing too much water, and the short 10-minute rest time lets flavors develop without becoming soggy. If your tomatoes are especially juicy, drain a little of the excess tomato liquid off before tossing.

Mistake 2: Over-mixing or under-seasoning

Tossing too vigorously can bruise the tomatoes and flatten the mozzarella. Be gentle with your spoon and use a folding motion rather than stirring aggressively. Also, it’s easy to underestimate seasoning in light salads. Taste after you toss and add a small extra pinch of salt or a touch more balsamic if it needs a little lift. Seasoning is about balance, not perfection.

Mistake 3: Changing ingredients without considering texture

Swapping ingredients is part of everyone’s kitchen life, but remember to think about texture continuity. For example, substituting a crumbly cheese will change how the salad feels; using a watery tomato can make it too loose. If you swap in goat cheese or a firmer heirloom tomato, adjust the dressing slightly (a bit more oil for creamier cheeses, a squeeze of lemon for firmer tomatoes) to keep the final result cozy and balanced.

Serving Suggestions for Cucumber Caprese Salad

This salad is a gentle companion to many meals — light, homey, and easy to pair. I love serving it as part of relaxed everyday dinners where everyone can graze and feel satisfied without fuss.

Weeknight family dinner side

Serve this Cucumber Caprese Salad alongside grilled chicken or a pan-seared fish fillet for a quick, balanced meal. The freshness pairs beautifully with simply seasoned proteins and a scoop of warm, gluten-free grain like quinoa or rice.

Picnic or potluck friendly

Because it holds up well at room temperature for a short while, this salad travels nicely in a covered bowl. Bring it to picnics or casual get-togethers with a loaf of gluten-free bread or crackers on the side for people who want a little crunch.

Light lunch or vegetarian main

Turn this into a light main by adding a scoop of cooked chickpeas or a handful of toasted pine nuts for protein and texture. Serve with lemon wedges and a small side of mixed greens for a satisfying, meat-free lunch.

Conclusion

I truly believe gluten-free cooking can be cozy, dependable, and delicious — not something to feel nervous about. This Cucumber Caprese Salad is one of those recipes I return to when I want a little comfort that’s also fresh and simple. It’s flexible, forgiving, and perfect for everyday life: a bowl that welcomes small changes without judgment, and always tastes like care.

FAQs About Cucumber Caprese Salad

Can I make the Cucumber Caprese Salad ahead of time?

Yes — you can assemble the salad up to a few hours ahead and keep it chilled. I recommend waiting to add any delicate fresh herbs or flaky salt until right before serving. If the tomatoes release extra juice, give the salad a gentle toss before you bring it out.

What gluten-free mozzarella or cheese options work in this Cucumber Caprese Salad?

Fresh mozzarella or bocconcini are ideal for their soft, milky texture. If you prefer something different, a soft goat cheese or ricotta can work nicely, but the flavor profile will shift a bit. All these choices are naturally gluten-free.

How can I keep the cucumber pieces from becoming soggy in Cucumber Caprese Salad?

Use firm cucumbers and slice them thin and evenly. If you’re worried about excess moisture, remove a little of the tomato juice before tossing, or salt the cucumber lightly and let it sit for 5 minutes, then pat dry — though I usually skip salting and simply rely on a short rest time to keep textures bright.

Is there a gluten-free dressing alternative for Cucumber Caprese Salad if I don’t have balsamic vinegar?

Absolutely. A simple mixture of olive oil with a squeeze of fresh lemon juice and a touch of honey can replace balsamic and remains gluten-free. Adjust seasoning to taste and sprinkle in the dried herbs the same way.

My family doesn’t love raw onion — how do I adapt the Cucumber Caprese Salad?

No problem. You can omit the red onion entirely, use thinly sliced scallions for a milder note, or rinse thin-sliced red onion briefly under cold water to soften the bite. Each option keeps the salad approachable and family-friendly.

I’m glad you’re exploring simple gluten-free recipes like this one — it’s all about small steps, cozy kitchens, and meals that make everyday life a little kinder.
