Fluffy Focaccia Topped With Tomato Slices, Basil, and Melted Cheese

This fluffy focaccia is topped with juicy tomato slices, aromatic fresh basil, and a generous layer of melted mozzarella cheese for the ultimate Italian comfort food.

Why This Recipe Works:

• High hydration (80%) ensures a moist, open crumb structure that stays soft for days.
• Cold fermentation develops complex, lactic acid-driven flavors while naturally relaxing the gluten.
• Dimpling the dough with olive oil creates pools of fat that fry the bottom crust to a crispy, golden finish.

My first real kitchen disaster happened in a cramped third-floor apartment in Florence, where I tried to bake bread in an oven that only had two settings: off and volcano. I ended up with a rock-hard slab of dough that could have easily doubled as a doorstop, which I promptly hid at the bottom of the trash bin so my roommates wouldn't laugh at me.

It was humiliating.

Years later, I learned that the secret to a truly pillowy crumb isn't fancy equipment, but the physical act of sinking your fingertips deep into the wet, oiled dough until they hit the bottom of the metal pan. You want to feel the yeast bubbles popping against your knuckles as you dimple the surface.

Most home bakers fail at focaccia because they treat it like standard homemade pizza dough, under-hydrating the flour and over-kneading the gluten matrix.

To fix this, we use an 80% hydration level and let time do the heavy lifting through a slow, cold fermentation in the fridge. This allows the starch gelatinization to occur naturally, creating those gorgeous, irregular air pockets that lock in moisture.

Trust me on this.

Ingredients

• 500g bread flour (preferably King Arthur, for high protein content)
• 10g Diamond Crystal kosher salt (about 1 tbsp)
• 7g instant yeast (1 packet)
• 400ml lukewarm water
• 60ml extra virgin olive oil (divided)
• 2 medium heirloom tomatoes, thinly sliced
• 150g low-moisture mozzarella cheese, shredded
• 1/2 cup fresh basil leaves
• Flaky sea salt (for finishing)

Directions

1. In a large bowl, whisk together the bread flour, Diamond Crystal kosher salt, and instant yeast.
2. Pour in the lukewarm water and stir with a spatula until a wet, sticky dough forms with no dry flour patches remaining.
3. Drizzle 15ml (1 tablespoon) of olive oil over the dough, cover tightly, and place in the refrigerator for 12 to 24 hours to ferment.
4. Pour 30ml (2 tablespoons) of olive oil into a 9x13-inch metal baking pan, coating the bottom and sides thoroughly.
5. Gently transfer the cold dough into the prepared pan, turning it once to coat it in oil, then let it rise at room temperature for 2 to 3 hours until puffy.
6. Preheat your oven to 425°F (220°C).
7. Pour the remaining olive oil over the dough, grease your hands, and press your fingers straight down into the dough until you touch the bottom of the pan to create deep dimples.
8. Arrange the tomato slices evenly across the surface, press them gently into the dimples, and scatter the shredded mozzarella cheese on top.
9. Bake for 22 to 25 minutes until the cheese is bubbly and golden brown, then garnish immediately with fresh basil and flaky sea salt before slicing.

Notes

• Salt Conversion: This recipe specifies Diamond Crystal kosher salt (10g or 1 tablespoon). If you are using Morton kosher salt, reduce the volume to 1.5 teaspoons (7g) to avoid over-salting the dough.
• Flour Science: High-protein bread flour (around 12.7% protein) is essential to support the high 80% hydration level and trap the carbon dioxide bubbles. All-purpose flour will result in a flatter, denser bread.
• Workflow Warning: Keep a close eye on the cheese during the last 5 minutes of baking. If your oven runs hot, tent the pan loosely with foil to prevent the mozzarella from scorching before the bottom crust is fully fried.
• Tomato Moisture: Fresh tomatoes release water as they bake. Pat the tomato slices dry with paper towels before placing them on the dough to prevent soggy patches.

Serving Suggestions

This cheesy, tomato-topped focaccia is incredibly versatile and can be enjoyed as a standalone snack, a side dish, or the base for an incredible sandwich.

• Pair it with a warm bowl of Creamy Tomato Soup for the ultimate elevated comfort meal.
• Serve alongside a bowl of Whipped Feta Dip for dipping the crispy, olive-oil-fried edges.
• Top with fresh prosciutto slices right before serving to add a savory, salty contrast to the sweet tomatoes.
• Drizzle with a high-quality balsamic glaze or hot honey for a sweet-and-savory kick.
• Slice it horizontally and use it as the bread base for a spectacular Chicken Caesar Wrap style sandwich.

Storage and Reheating

If you somehow end up with leftovers, store them in an airtight container at room temperature for up to two days. Do not put this bread in the refrigerator, as the cold environment will accelerate starch retrogradation, turning your beautiful, springy crumb dry and stale.

Because of the high moisture content in the fresh tomato slices, the top of the focaccia will naturally soften over time. To combat this, avoid using a microwave to reheat it, which will only turn the dough rubbery and tough.

Instead, pop the slices onto a wire rack set inside a baking sheet and bake at 375°F (190°C) for about 8 to 10 minutes. This allows the hot air to circulate underneath, refrying the bottom crust in its own residual olive oil while melting the cheese back to its original, gooey glory.

Ingredient Substitutes

If you need to adapt this recipe based on what you have in your pantry, here are the most reliable swaps:

1. Bread Flour: You can substitute all-purpose flour, but reduce the water by 30ml to compensate for the lower protein content.
2. Fresh Tomatoes: If heirloom tomatoes aren't in season, halved cherry tomatoes work beautifully and release less water.
3. Mozzarella: Provolone or fontina make excellent melting alternatives if you want a sharper flavor profile.
4. Fresh Basil: If you don't have fresh basil, a drizzle of Sun Dried Tomato Pesto over the baked bread adds a wonderful herbal depth.

There is something deeply therapeutic about baking your own bread, especially when it involves pressing your fingers into a pillowy cushion of dough. Pour yourself a glass of wine, let the yeast do its magic, and enjoy the smell of bubbling cheese filling your kitchen.
