To 425 degrees and line a large, rimmed baking sheet with parchment paper.
Add cauliflower florets to a large bowl and toss with oil, dried spices, salt, and pepper – making sure the spices are well distributed. Transfer to a baking sheet and spread out the cauliflower until evenly spaced.
Transfer to the oven and bake, flipping halfway through, for about 20-26 minutes, or until cauliflower pieces are tender and nicely caramelized. You can always roast for a little bit longer for extra crispy florets!
Remove cauliflower from the oven and serve topped with fresh cilantro, red or green onion, lime wedges, and avocado if desired.
