Chop the cauliflower into florets. Peel and mince the garlic.
In a large bowl, mix the cauliflower and garlic with the olive oil, cumin, paprika, turmeric, red pepper flakes, salt, and black pepper.
Line a large baking sheet with parchment paper or a silicone mat, then place the cauliflower in a single layer on the baking sheet. Roast for 25-35 minutes or until the cauliflower is tender and browned, stirring once. Serve immediately.
Note-you can swap the red pepper flakes for 1 Fresno chile pepper, seeds removed, and minced if you wish.
