01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, toss the broccoli florets with olive oil, sea salt, and black pepper until evenly coated.
03 - Spread the broccoli on the prepared baking sheet in a single layer. Roast for 18–20 minutes, turning halfway through, until the edges are crispy and the stems are tender.
04 - While the broccoli roasts, whisk together the tahini, lemon juice, grated garlic, chopped parsley, dill, sea salt, and lemon zest in a medium bowl. Gradually add water, 1 tablespoon at a time, until the sauce reaches a creamy, pourable consistency.
05 - Arrange the roasted broccoli on a serving platter and drizzle generously with the lemon herb tahini sauce.
06 - Finish with extra chopped herbs and lemon wedges if desired. Serve warm or at room temperature.
