Preheat the Oven
Preheat to 425°F (220°C) and line a baking sheet with parchment paper or a silicone mat for easy cleanup.
Slice the Zucchini
Cut into 1/4-inch thick rounds. Uniform slices ensure even baking.
Toss with Oil and Seasoning
In a large bowl, toss zucchini with olive oil, garlic, salt, pepper, and Italian seasoning.
Arrange and Sprinkle
Lay zucchini slices in a single layer (not overlapping!) on the prepared baking sheet. Sprinkle Parmesan evenly over the top.
Bake
Bake for 18–22 minutes, until the cheese is golden and zucchini is tender. For extra crispiness, broil for 2 minutes at the end—but watch closely!
Serve
Garnish with parsley, red pepper flakes, or a squeeze of lemon juice. Serve hot for the best texture.
