Prepare the cauliflower. Remove the outer green leaves and cut the cauliflower in half. Remove the central core of the cauliflower, and roughly chop or break the cauliflower into florets.
Place cauliflower florets in a bowl and toss with olive oil and spices. Ensure that cauliflower is well and evenly coated with oil and spices.
Season with sea salt and fresh cracked pepper.
Place cauliflower florets onto a baking sheet and spread them out evenly. You want to allow some room between the florets in order for them to crisp up in the oven.
Place in oven and bake for 30-35 minutes. Keep a close eye on them, and you may want to toss them around a couple of times during the cooking time to ensure all sides cook evenly.
For extra crispiness, broil for 3-5 minutes on high.
