01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Toss zucchini slices with olive oil, kosher salt, and black pepper in a large bowl until evenly coated. Arrange in a single layer on the prepared baking sheet.
03 - Roast for 22–25 minutes, flipping the slices halfway through, until golden brown and fork-tender.
04 - While the zucchini roasts, toast sesame seeds in a dry skillet over medium heat for 3–4 minutes, stirring frequently, until golden and fragrant. Remove from heat and let cool slightly.
05 - In a small bowl, combine the toasted sesame seeds, parsley, mint, dill, minced garlic, lemon zest, lemon juice, extra-virgin olive oil, and flaky sea salt. Stir until well mixed.
06 - Transfer the roasted zucchini to a serving platter. Spoon the sesame herb crunch generously over the top. Serve warm or at room temperature.
