Preheat oven to 400 F and prepare a baking sheet with parchment paper or tin foil.
In a large mixing bowl, stir together the olive oil, garlic, seasonings, salt, and pepper. Cut the cauliflower into florets and toss with the olive oil mixture until evenly coated.
Transfer the florets to the baking sheet and bake for 35 -40 minutes or until tender and roasted.
