Preheat the oven to 400F and line a baking sheet with parchment paper.
Season:
In a large bowl, combine the Sriracha, honey, soy sauce, red pepper flakes, and oil, and whisk until smooth.
Add the chopped cauliflower florets to the bowl and toss to coat with the sauce.
Roast:
Transfer the cauliflower to the lined baking sheet and roast for 25 minutes until the cauliflower tops are golden and the cauliflower is tender when poked with a fork.
