The short version
Salt sliced ripe tomatoes and let them drain, then layer them with fresh mozzarella and basil on split focaccia dressed with olive oil, salt, and pepper. Serve soon after building. Bake or buy the focaccia base first (see our classic focaccia).
Why this works
Ripe tomatoes carry a lot of water; salting and draining them first concentrates their flavor and keeps the focaccia from turning to mush. Fresh mozzarella, patted dry, adds cool milkiness, and basil torn (not chopped) stays fragrant. Olive oil and a little of the drained tomato juice season the crumb without soaking it through.

Ingredients
Method
- 1
Salt the tomatoes
Slice the tomatoes thick, lay them on a plate or in a colander, sprinkle with a little salt, and leave 10 minutes. Pat the tops dry and reserve a spoonful of the drained juice.
Look for: The slices release watery juice and their flavor concentrates — this keeps the sandwich from going soggy.

Ready the focaccia
If baking your own, follow our classic focaccia and let it cool. Cut the slab into 4 pieces and split each horizontally. Drizzle the cut sides with olive oil and a little of the reserved tomato juice.
Look for: The oil and juice should just gloss the crumb, not soak it.
- 3
Layer
On each bottom, alternate tomato and mozzarella slices, tucking basil leaves between them. Season with flaky salt and black pepper.
Look for: Aim for even layers so every bite has tomato, cheese, and basil.

Dress and close
Drizzle with more olive oil (and a few drops of balsamic if using), set the top back on, and press gently.
Look for: A light press should just hold it; you should see juice bead at the edges.
- 5
Serve
Serve soon after building, while the tomatoes are at room temperature and the bread is still crisp-edged.
Look for: Best within the hour — the longer it sits, the softer the crumb.
What good looks like
- Crumb: Soft focaccia lightly soaked with olive oil and tomato juice.

If something went wrong
| Symptom | Likely cause | Fix |
|---|---|---|
| Soggy, falling-apart sandwich | Tomatoes not drained | Salt and drain the tomato slices and pat them dry before layering. |
| Watery, bland tomato | Under-ripe or out-of-season tomatoes | This sandwich needs peak-season, fully ripe tomatoes — season generously if they’re average. |

Frequently asked
- Should I use balsamic?
- A classic caprese uses none, but a few drops of good balsamic on the sandwich is a common home touch — keep it light so it doesn’t drown the tomato.
- Can I make it ahead for a picnic?
- Keep the drained tomatoes, mozzarella, basil, and split focaccia separate and assemble just before eating so the bread stays crisp.
