Place rack in center of oven then preheat to 400 degrees. Line baking sheet with parchment paper then coat with cooking spray.
Wash cauliflower florets under cool water then set aside in a colander to drain excess water. Transfer dry florets to a large bowl then drizzle with olive oil. Toss to coat each floret evenly with the oil.
Sprinkle garlic powder, chili powder, salt, pepper and paprika over the florets, tossing frequently to distribute the seasoning evenly.
Place seasoned cauliflower on prepared baking sheet then bake anywhere from 15–25 minutes depending on the size of your florets and desired tenderness. Remove from oven then serve immediately. Enjoy!
Notes
I prefer my cauliflower crispy on the outside and smooth on the inside—so if you’re like me, let these guys roast for the full 25 minutes!
