01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss zucchini slices with olive oil, lemon juice, lemon zest, sea salt, and freshly cracked black pepper until evenly coated.
03 - Arrange the seasoned zucchini in a single layer on the prepared baking sheet, ensuring none overlap.
04 - Sprinkle freshly grated Parmesan cheese evenly over each zucchini round.
05 - Bake for 15-18 minutes until zucchini is tender and Parmesan is golden and bubbly. For extra crispiness, broil for an additional 1-2 minutes.
06 - Transfer to a serving plate, garnish with fresh chopped parsley if desired, and serve immediately.
