Set your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it to make cleanup easier later.
Slice the loaf of Italian bread in half horizontally. For easier sharing or snacking, you can also cut it into individual slices. Arrange them cut-side up on the baking sheet.
In a small bowl, combine the olive oil or melted butter with minced garlic and Italian seasoning. Use a pastry brush to coat each bread slice evenly with this mixture. Be generous—this is where the flavor begins.
Layer the tomato slices over the garlic-coated bread. Slightly overlap them if you’re working with smaller slices. Sprinkle salt and pepper lightly to bring out the tomato’s natural sweetness.
Cover the tomatoes with shredded mozzarella cheese. If you want a sharper, nuttier flavor, dust some Parmesan over the top too.
Place the baking sheet in the oven and bake for 10–15 minutes. Look for melted cheese that’s golden and bubbling, and edges of the bread that are crisp and toasted.
Remove from the oven and immediately scatter chopped fresh basil on top. The residual heat will release the basil’s fragrance without wilting it entirely.
Slice into portions and serve while hot. Perfect as an appetizer, a light lunch, or a fun addition to pasta night.
