Preheat oven to 425°F.

Cut the cauliflower into bite-sized pieces; transfer to a large bowl; set aside.

In a small bowl, combine olive oil, sriracha, maple syrup, salt, and pepper.

Pour the sriracha mixture over the cauliflower and mix well, ensuring the cauliflower is well coated in the sauce.

Spread the cauliflower onto a large baking sheet and bake for 20 minutes, stirring once at the halfway point.

Increase the oven temperature to 475°F and bake for another 12 minutes, or until golden brown.

Serve at once.
