Toast the bread slices in your toaster or under the broiler until they're golden brown and crispy all the way through. You want some real crunch here — this toast is the foundation and needs to hold up to the juicy tomato topping.
⏱ 3 min
Slice each tomato in half horizontally, then hold the cut side against the large holes of a box grater. Grate the flesh into a bowl, working until you reach the skin — then toss those peels. You'll end up with a chunky, jammy tomato pulp that's perfect for spreading.
While the toast is still warm, rub each slice with the cut garlic clove if you're using it. The rough surface of the bread will grab the garlic and infuse each bite with subtle flavor.
Spoon the grated tomato evenly across each toast slice, spreading it edge to edge. Don't be shy — you want a generous layer of that sweet tomato pulp covering every inch.
Drizzle the olive oil generously over the tomato-topped toasts, then finish with a pinch of coarse salt on each one. The salt draws out the tomato juices and makes everything taste more vibrant.
Arrange the serrano ham slices over the top, letting them drape naturally over each toast. Serve immediately while the bread is still crisp and the flavors are at their brightest.
