Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper, if desired.
In a large mixing bowl, whisk together the olive oil, honey (or maple syrup), soy sauce, sriracha sauce, garlic powder, smoked paprika, salt, and black pepper until well combined.
Add the cauliflower florets to the bowl and toss them in the marinade until they are evenly coated.
Spread the coated cauliflower florets in a single layer on the prepared baking sheet, ensuring they are not overcrowded for even cooking.
Bake in the preheated oven for 25 minutes, or until the cauliflower is golden brown and crisp-tender. Toss the florets halfway through for better browning.
Once baked, remove from the oven and let cool slightly. Garnish with sliced green onions and sesame seeds if desired.
Serve warm as a side dish or snack. Enjoy!
