01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, toss cauliflower florets with olive oil, minced garlic, cumin, smoked paprika, salt, and black pepper until evenly coated.
03 - Spread cauliflower in a single layer on the prepared baking sheet. Roast for 25-30 minutes, turning halfway, until golden brown and crisp-tender.
04 - While the cauliflower roasts, whisk together tahini, lemon juice, maple syrup, water, minced garlic, and salt until smooth. Add more water for a thinner consistency if desired.
05 - Transfer roasted cauliflower to a serving platter. Drizzle generously with tahini sauce. Garnish with chopped parsley and toasted sesame seeds if desired. Serve warm.
