Ingredients

• 1 ciabatta loaf
• 3 Tbsp. extra-virgin olive oil, plus more for drizzling
• 2 garlic cloves, halved crosswise
• 2 lb. heirloom tomatoes, cored
• Flaky sea salt
• Freshly ground black pepper, chopped oregano, and/or oil-packed anchovy fillets (for serving; optional)

Instructions

1. Preheat oven to 300°F. Holding a bread knife so it’s parallel with work surface, slice ciabatta in half lengthwise (like opening a book). Slice each piece in half lengthwise down the center, then cut each strip on a diagonal into 4 pieces (you should have 16 pieces total).
2. Drizzle 3 Tbsp. oil over bread and rub each piece to evenly distribute oil. Place bread on a rimmed baking sheet and bake until lightly browned and dried out, 30–40 minutes. Rub warm toast with cut sides of garlic; set aside.
3. Meanwhile, slice a thin round off the bottom of each tomato. Starting at cut end, grate tomatoes on the largest holes of a grater into a medium bowl until all that’s left are the flattened tomato skins. Finely chop skins and mix into grated flesh; season very generously with salt.
4. Spoon a generous amount of tomato sauce over each toast (you may have some left over). Let sit at least a minute or two so bread can absorb some of the juices. Drizzle with oil, sprinkle with more salt, and top as desired.
