Roasted Tomato Caprese Sandwich

A classic caprese sandwich layers fresh mozzarella, ripe tomatoes, and basil on bread with a touch of olive oil. This version takes a richer, deli-inspired approach with roasted tomatoes, basil pesto, a drizzle of balsamic vinegar, and prosciutto on a toasted baguette.

I kept the heart of a traditional caprese sandwich recipe, but built in a little more depth. Instead of fresh tomatoes, I use tomato confit, slow-roasted until soft, sweet, and jammy. The basil pesto brings a more concentrated, herby flavor, while the prosciutto adds that salty contrast. A splash of aged balsamic cuts through with just enough tang to balance everything out. It’s simple at its core, just layered to hit that balance of sweet, salty, and tangy in every bite.

What is a Caprese Sandwich?

A caprese sandwich is a simple Italian-inspired sandwich made with fresh mozzarella, tomatoes, and basil on bread, typically finished with olive oil and salt. It’s based on the classic Caprese salad and highlights fresh, balanced flavors.

Tools You’ll Need

• Baking Dish
• Cast Iron Skillet

• Baguette — I use a crusty baguette because it holds up well once toasted and gives the sandwich structure without getting soggy
• Prosciutto — I add this for a salty, savory layer that balances the sweetness of the tomatoes and the richness of the cheese
• Buffalo mozzarella — Soft, creamy, and slightly tangy, this is what gives the sandwich that classic caprese feel
• Tomato confit — I slowly roast the cherry tomatoes until they’re soft, sweet, and jammy, which adds depth and a more concentrated tomato flavor
• Basil pesto — I use pesto instead of fresh basil for a more concentrated, herby flavor that spreads easily across the bread
• Aged balsamic vinegar — Just a small amount adds a tangy finish that cuts through the richness and ties everything together
• Kosher salt — A pinch goes a long way in bringing out the natural flavors of the tomatoes and mozzarella
• Olive oil — I use this to toast the bread and add a subtle richness that carries through each bite
• Garlic — I rub the toasted bread with garlic for a light, savory depth that doesn’t overpower the other ingredients

Prepare the Tomato Confit

Once the tomato confit is done roasting, I let it cool completely so it doesn’t melt the cheese too quickly or make the bread soggy. The oil and garlic from the confit are just as important as the tomatoes, so I make sure to keep all of that for assembling later.

Toast the Bread

I heat a cast iron skillet over medium heat, then slice the baguette into thirds and split each piece lengthwise. After drizzling the cut sides with olive oil, I toast them until golden and crisp, working in batches if needed. While the bread is still warm, I rub each piece with garlic to build that subtle layer of flavor right into the base.

Assemble the Sandwich

On the bottom half, I spread a generous layer of basil pesto, then add the prosciutto so it lays evenly across the bread. The top half gets the buffalo mozzarella, lightly seasoned with salt, followed by the tomato confit along with some of its oil and softened garlic.

Finish and Serve

Once everything is layered, I bring the two halves together and finish with a light drizzle of aged balsamic. Each section gets sliced into thirds, making it easy to serve right away while the bread is still crisp and everything inside is perfectly balanced.

Recipe Variations

• Chicken Caprese Sandwich — Add grilled or pan-seared chicken for a more filling option that pairs well with the pesto and roasted tomatoes
• Vegetarian — Skip the prosciutto and let the tomato confit, mozzarella, and pesto carry the sandwich with a balanced mix of flavor and texture
• Balsamic Glaze — Swap the aged balsamic vinegar for a thicker glaze if you want a slightly sweeter finish that clings to each bite

What to Serve with Caprese Sandwiches

Personally, I love this sandwich as is, but if you want to serve it with another dish, here are my suggestions.

• Simple green salad — Pair it with this Green Goddess Salad for a fresh, herby side that complements the sandwich without overpowering it.
• Potato chips — A salty, crunchy side that adds texture and keeps things easy.
• Pasta salad — A chilled pasta salad pairs well and makes this feel more like a full meal.
• Roasted vegetables — Seasonal vegetables add warmth and depth without overpowering the sandwich.
• Soup — Roasted Red Pepper and Tomato Soup works well if you’re serving this as a more comforting meal.
