01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper for easy cleanup.
02 - In a large bowl, combine the cauliflower florets with olive oil, turmeric, cumin, smoked paprika, salt, and black pepper. Toss thoroughly until each floret is evenly coated with the spice mixture.
03 - Spread the seasoned cauliflower in a single layer on the prepared baking sheet, ensuring pieces are not overcrowded for proper caramelization.
04 - Roast for 22-25 minutes, stirring halfway through cooking, until florets are golden and tender with crisp, caramelized edges.
05 - Transfer to a serving platter. Garnish with fresh cilantro or parsley and serve with lemon wedges if desired.
