Choose and prep your tomatoes: Pick ripe but firm heirloom tomatoes. Rinse gently, pat dry, and slice into thick rounds or wedges. If there’s a lot of juice, let the slices sit on a paper towel for a minute.
Drain the mozzarella: Remove the buffalo mozzarella from its liquid.
Tear it into large, rustic pieces. Tearing creates more nooks and crannies for olive oil and juices.
Arrange the plate: On a large platter, alternate layers of tomato slices, torn mozzarella, and whole basil leaves. Don’t pack it too tight—leave space so everything breathes.
Season generously: Sprinkle with flaky sea salt and black pepper.
Season the tomatoes directly so their flavor pops.
Finish with olive oil: Drizzle extra-virgin olive oil over the entire plate. Use enough to lightly gloss the tomatoes and cheese.
Add optional accents: If you like, add a light drizzle of balsamic or balsamic glaze, and a bit of lemon zest for lift. Keep it minimal so the tomatoes stay front and center.
Serve right away: This salad is best at room temperature.
Serve with crusty bread to mop up the juices and oil.
