Preheat the oven to 425°F. Remove the outer leaves on the cauliflower, then rinse the cauliflower well. Cut the head into quarters, then slice off the core. Break the remaining cauliflower into large florets.
Place the florets onto a parchment-lined baking sheet. Drizzle with olive oil, your favorite seasoning, and salt (if your seasoning does not contain salt). Toss the cauliflower until well coated in oil and seasonings. Spread the cauliflower out evenly over the baking sheet, making sure it's not too crowded.
Roast the cauliflower for about 25 minutes, stirring once halfway through, or until the cauliflower reaches your desired level of browning.
