01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss zucchini rounds with olive oil, sea salt, and black pepper until evenly coated.
03 - Arrange the seasoned zucchini in a single layer on the prepared baking sheet, ensuring none overlap.
04 - Roast for 20–25 minutes, flipping the rounds halfway through, until golden and fork-tender.
05 - While the zucchini roasts, whisk together tahini, lemon juice, minced garlic, parsley, dill, salt, and pepper in a small bowl. Slowly add water while whisking until the sauce reaches a creamy, pourable consistency.
06 - Transfer roasted zucchini to a serving platter. Drizzle generously with the lemon herb tahini sauce. Serve warm or at room temperature.
