Cauliflower florets in oven - Cut end and leaves off of cauliflower and discard. Rinse and pat dry with paper towels. Cut into large bite size pieces and put into a large bowl. Preheat oven to 400 degrees F.
Pour oil over florets and toss to coat. Sprinkle in seasonings, toss to coat. Pour on to your non stick large baking sheet and spread out so there is as little overlapping as possible.
Bake for approximately 30 minutes (will vary depending on how large your pieces are), ideally flipping pieces halfway thru. Remove once pieces are fork tender to your liking and browned on top.
** If you would like to add parmesan, sprinkle over the top during the last 10 minutes so it can melt and bake on to veggies.
Whole cauliflower in oven - Preheat your oven to 400°F. Remove any leaves, keep the core intact but cut so it is flat. Rinse under cold water and pat it dry with paper towels. Place on top of a baking sheet. Drizzle on olive oil, sprinkle with salt, pepper, and your favorite herbs or spices.
Roast in the preheated oven for about 45 minutes to 1 hour, depending on the size. Check for doneness by inserting a fork or knife into the thickest part. Can sprinkle parmesan on top during the last 10 minutes if desired.
