01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - Toss broccoli florets with olive oil, sea salt, and black pepper until evenly coated. Spread in a single layer on the prepared baking sheet.
03 - Roast for 20–25 minutes, tossing halfway through, until the edges are deeply browned and crispy.
04 - While the broccoli roasts, whisk together tahini, lemon juice, warm water, maple syrup, grated garlic, and salt until smooth and pourable. Add additional warm water, 1 teaspoon at a time, if the dressing is too thick.
05 - In a dry skillet over medium heat, toast sesame seeds and pumpkin seeds for 2–3 minutes, stirring constantly, until fragrant and lightly golden. Remove from heat and stir in the crispy shallots and parsley if using.
06 - Transfer the roasted broccoli to a serving platter. Drizzle generously with the tahini dressing and sprinkle the crunchy topping over the top. Serve warm or at room temperature.
