Preheat the oven to 400F.
Wash the cauliflower, then trim and cut into florets.
Dry the florets thoroughly using a kitchen towel.***
In a large bowl, toss the florets with the olive oil, salt, and pepper. Really toss it thoroughly, so the oil is as evenly dispersed as possible.
Scrape the cauliflower (and any oil from the bowl) onto a baking sheet, spreading it evenly in a single layer on the pan.
Roast for 25 minutes, until the tips and edges of the cauliflower are starting to brown.
Using a flat turner, toss all the pieces around and re-arrange in an even layer.
Roast for another 10-15 minutes, until the cauliflower is brown and caramelized all over.
Serve and enjoy!
