Preheat the oven to 400 degrees and line a large rimmed baking sheet with parchment paper or spray with non-stick spray.
Prepare the bread: trim off and discard the ends of the French bread loaf, then slice the bread into ½ inch thick slices. Eyeball it. Arrange the bread on the baking sheet.
In a small bowl combine 4 tablespoons olive oil with 1 teaspoon Italian seasoning.
Brush the top side of each slice of bread with the olive oil mixture.
Bake for 4-5 minutes. Remove the bread from the oven and rub a peeled garlic clove over each slice of bread.
Flip the bread so the olive oil side is down, then top each piece of bread with mozzarella cheese.
Bake for 4-5 minutes longer, or until the cheese is melted and the bread is well toasted.
