Caprese Salad (Insalata Caprese): The Italian Classic That Needs Great Tomatoes

Caprese salad has been one of my favorite salads for years. It’s served often in restaurants in the States. And I loved it. It’s always the best flavors of summer, especially when you get one served with a vine ripened tomato. Unfortunately, most of the ones served in the restaurants in the States are pale pink tomato slices, rubbery pre-sliced mozzarella, a couple of sad basil leaves, a balsamic drizzle, and a bottle of olive oil that had probably been sitting on the shelf since before I arrived.

I really didn’t realize the true difference until eating our first one in Italy. Then I fully got it. What an insalata caprese is supposed to be. Thick slabs of a vine-ripened tomatoes, cut almost like a steak, still warm from the sun. Never been in the fridge. Fresh mozzarella made that morning… creamy and soft and nothing like anything you can buy in a standard grocery store (check your local Italian store in the States). A few torn basil leaves. A drizzle of good olive oil. NO balsamic vinegar. That’s it. And you’ve got OMG delicious.

The difference isn’t technique. It’s ingredients. This is one of those salads where you’ve got to use the best ingredients from the start. That’s the only way you’re going to get the best flavors.

Why the Tomato Is the Whole Point

You can’t fake your way through a caprese salad. There’s nowhere to hide subpar ingredients. No sauce, no spice blend, no cooking technique to paper over a mediocre ingredient. This dish lives or dies entirely on the quality of your tomatoes, and until you’ve had a caprese made with a truly ripe, farmers market heirloom tomato or one picked straight from the vine, you haven’t fully experienced what this dish actually is.

We get our tomatoes at the Praça da Fruta here in Portugal… the daily farmers market where the heirlooms come in big, gorgeous, deeply colored slabs starting in May through September. The hubby and I wait for them. Properly. When the first good ones hit the market, a lovely heirloom tomato salad or caprese goes on the table that same afternoon.

Thick slices are non-negotiable. I cut them almost as you would a steak. I like half inch thick slabs. Substantial enough to hold up against the mozzarella. And you don’t want to miss the best part… the combined juices at the end. Cause when a tomato is truly ripe, the juices pool on the platter and mix with the olive oil. A good crusty bread is an absolute must for sopping them up. Don’t leave them sitting in the bowl.

Using Supermarket Tomatoes

Don’t. They are picked green so they ship without bruising and can sit on the shelf for days, if not weeks. They don’t develop the flavors because they weren’t ripened on the vine. Instead, get them from your local farmers market or farm box delivery. Or grow them yourself. A pot on the balcony or a plot in a local community garden can produce some beautiful tomatoes.

A Brief and Beautiful History of Insalata Caprese

The caprese salad takes its name from the island of Capri off the Amalfi Coast, where it’s said to have originated. As with any recognized dishes, there’s plenty of disagreement over who created it or the exact location it comes from. All we know for sure it that it seems to have been developed in the early 20th century. It’s possible it became the ‘salad of Italy’ because it’s the colors of the Italian flag: green basil, white mozzarella, red tomato. It’s seems to have made it’s way to the States in the 1950’s.

It Italy it’s served as an antipasto, a starter before a meal, with nothing but olive oil for dressing. Adding balsamic vinegar seems to be a US adaptation, and the Italians will tell you so. The simplicity is the whole point. Three ingredients (four if you count the olive oil) that showcase the quality of what they’re made from.

Mozzarella itself has equally ancient roots in the Campania region, made from the milk of water buffalo that were brought to southern Italy centuries ago. Buffalo mozzarella — mozzarella di bufala — is protected by a DOP designation in Italy, which means it can only be made in specific regions from buffalo milk. What you get outside Italy, even good-quality fresh mozzarella, is made from cow’s milk and is technically a different product. Still delicious, especially from a good cheesemaker, and while not the same thing, is a good substitute if you can’t get the real deal. Buy a ball and slice your own at home. Don’t do pre-sliced.

Olive Oil Is Not a Finishing Touch — It’s a Main Ingredient

In my world, olive oil is not a background player in this salad or any other dish. But with insalata caprese it IS the dressing. It’s the thing that ties the tomato juice, the creamy mozzarella, and the basil together into a single flavor experience. Which means the quality of your oil matters enormously.

The hubby and I are olive oil snobs. We usually have three or four special bottles in the house at any given time, each for a different purpose. Finishing dishes gets the good stuff, always.

One of my absolute favorites here in Portugal is from D’Olival Azeites in Marvão, a small producer making beautiful oil from a very specific corner of the country. When we’re in Italy, I haul bottles back in my suitcase. Literally. Half a dozen at a time. My all-time favorite in the world is Frantoio Gaudenzi, a sharp, peppery, almost florescent green, an Umbrian producer I discovered during our time living in the little town of Trevi. Yes, please. (I’m not an affiliate of either of these places – they are just some of my favorite places to buy olive oil).

For this salad, use whatever is the best olive oil in your house. This is not the moment for the everyday cooking oil.

On Finishing Salts and Why They Matter Here

We’ve always used good finishing salts in our home. Hand harvested sea salts from around the world, in a rainbow of colors – black, pink, yellow. Even different smoked versions. But last year, our friends Els and Bob introduced us to these incredible flavored finishing salts made near the Spanish border in the south of Portugal. Flavored with citrus, olives, and even a red porto wine version.

Recently I made my own limoncello salt using hand-harvested Portuguese sea salt from Rio Maior blended with the lemon peel left over from making homemade limoncello. I finished this caprese with that. The citrus note plays beautifully with a really good tomato and cuts through the richness of the mozzarella in a way that plain salt just doesn’t.

This isn’t the place for table salt or Kosher salt. Because caprese salad rewards those kinds of details. If you don’t have a favorite sea salt, use a good flaky sea salt (Maldon is the reliable go-to).

Fresh Mozzarella — What to Look For

Fresh mozzarella should be soft, white, and swimming in liquid when you buy it. The pre-sliced stuff sealed in plastic without any liquid isn’t the same product. What you want is a ball or log that you slice yourself. You’ll feel the difference immediately when you cut into it.

Buffalo mozzarella is my first choice here. It’s richer, creamier, and has a slightly tangy flavor that pairs beautifully with sweet summer tomatoes. It can be harder to find in some areas of the US, but most Whole Foods or Italian delis carry it, and it’s absolutely worth seeking out for this dish specifically. If you have a local Italian deli, go there because it’s quite often made fresh locally, if not in house.

Here in Portugal, I sometimes go less traditional and swap the mozzarella entirely for a gorgeous fresh goat cheese or sheep’s milk cheese from a local producer. It’s not traditional caprese, but it’s still so delicious with a different tang and texture.

The key is to use fresh ingredients, no matter what you choose.

Fresh Basil — Hand-Torn, Please

Cutting basil with a knife turns the edges black almost immediately. It doesn’t ruin the flavor, but it makes a beautiful salad look a bit sad around the edges. Hand-torn basil keeps its color longer and honestly looks more generous and casual on the plate.

If you do need to chop it, maybe the leaves are very large and a chiffonade makes sense, do it at the very last second, right before serving. Don’t prep it in advance and let it sit.

Whole leaves are also completely fine and I use them often. Guests can cut through them with a knife and fork along with the tomato and mozzarella. It’s all easy peasy.

If you grow your own basil (I keep several pots of it on my kitchen windowsill here), this is the moment to go pick it fresh. The difference between basil cut from a plant and basil that’s been sitting in a bag for a few days is real and noticeable in a dish this simple.

How We Serve Caprese Salad — and the Pesto Version

In Italy, caprese is served as an antipasto — before the meal, as a starter. At home, with thick slices of bread for sopping up the tomato-olive oil juices from the platter, we often eat it as a light lunch on its own. It’s cooling and satisfying without being heavy, which makes it exactly right for a hot summer afternoon. But it’s also beautiful as the starter before this delicious Pollo alla Cacciatora in Bianco (Chicken Cacciatore in White Wine).

The hubby and I pair it with a chilled glass of rosé or a crisp white. Something with a little acidity that plays well with the tomato. It’s the kind of lunch that feels indulgent but takes literally ten minutes to put together.

For winter, or when fresh basil is out of season, we make a pesto caprese instead. A smear of homemade pesto on the plate before adding the tomatoes and mozzarella, with a few fresh basil leaves scattered on top if we have them. We make and freeze big batches of pesto each summer from our own kitchen where we grow large pots of basil by the sliding glass doors. Then we have summer tastes in the winter, including with these roasted cherry tomatoes.

Crusty bread, always. That’s the final non-negotiable. Because the juice situation at the bottom of the platter… yes, I’m talking about those juices again… is frankly the best part. It’s kinda like the cereal milk at the bottom of the bowl. And bread is the way to go to not waste it. So, what about you… love sopping up the juices at the end of the salad? Let me know in the comments. And don’t forget to drop any questions there.

Recommended Ingredients & Tools for Caprese Salad

Here’s what makes a real difference with this one — and since the dish is so simple, quality is everything:

Ingredients

Fresh Buffalo Mozzarella — If you can get it, get it. Buffalo mozzarella is creamier and richer than cow’s milk mozzarella and it’s the authentic choice for insalata caprese. Look for it swimming in liquid, not sealed in dry plastic.

Flaky Sea Salt — Maldon sea salt flakes are the reliable finishing salt for this. Light, flaky, and they don’t just make things “salty” — they add texture and brightness. If you can find a flavored finishing salt locally, this is a great dish to try it on.

Extra Virgin Olive Oil — High Quality — Use the best olive oil in your pantry. This isn’t the moment for everyday cooking oil. A peppery, grassy EVOO with some character is what you want here.

Tools

Mandoline Slicer — Optional, but if you want perfectly even slices for a more formal presentation, a mandoline does what a knife can’t quite match. That said — for this salad, rustic and thick is the spirit, so don’t overthink it.

Large Flat Serving Platter — Caprese needs room to spread out. A wide, flat platter lets you layer the tomatoes and mozzarella properly and gives space for the olive oil and juices to pool. A deep bowl is the wrong vessel for this.

Good Chef’s Knife — My personal favorite is the Shun. A sharp knife makes a real difference when you’re cutting thick slabs of ripe tomatoes. A dull knife squashes rather than slices, and these tomatoes are too good for that.

Frequently Asked Questions About Caprese Salad

• Does authentic Italian caprese salad have balsamic vinegar? No — traditional insalata caprese uses only olive oil, no vinegar of any kind. The balsamic drizzle version is an international adaptation. If you love a few drops of a very good aged balsamic (the thick, syrupy kind, not the acidic salad-dressing kind), that’s a personal call — but know that in Italy, it’s olive oil only.
• What type of tomatoes are best for caprese salad? Ripe, farmers-market or garden-fresh heirloom tomatoes are ideal — any variety with color, depth, and juice. The key word is vine-ripened. Supermarket tomatoes picked green and ripened in transit have very little flavor by comparison. This dish is worth waiting for until you have genuinely good tomatoes.
• Can I make caprese salad ahead of time? Not really — at least not fully assembled. The tomatoes release juice quickly once salted, and the basil blackens after being torn. Your best approach is to slice everything and keep the components separate in the fridge (tomatoes at room temp, mozzarella briefly refrigerated), then assemble and dress right before serving.
• What can I use instead of fresh mozzarella? Fresh goat cheese, burrata, or a good sheep’s milk cheese all work beautifully. Burrata in particular is becoming a popular substitute — it has a creamy, almost liquid center that makes the dish even more luscious. Each gives a slightly different flavor profile, but all of them work with ripe tomatoes and good olive oil.
• What’s the best way to store leftover caprese salad? Honestly, this one doesn’t store well once assembled — the tomatoes get soggy and the basil blackens. If you have leftover components, store them separately and reassemble the next day. Leftover tomato and mozzarella that have already been dressed are best used in a quick pasta or bruschetta situation rather than served as caprese again.
• What wine pairs well with caprese salad? A chilled rosé or a crisp Italian white is the classic call — Pinot Grigio, Vermentino, or a light Soave all play well with the tomato acidity and creamy mozzarella. If you’re having it as part of a bigger Italian spread, whatever white you’re serving with the rest of the meal will work.
