Using a mandoline slicer or a sharp knife, thinly slice the zucchini lengthwise.
Arrange the zucchini slices on a serving platter.
In a small bowl, whisk together the olive oil, lemon juice, salt, and pepper to make the dressing.
Drizzle the dressing over the zucchini slices.
Sprinkle the shaved Parmesan cheese on top.
Garnish with fresh basil leaves.
Serve immediately and enjoy!
