Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or a silicone baking mat for easy cleanup.

Prepare the Cauliflower:

Wash the cauliflower thoroughly and pat it dry. Divide it into individual florets, ensuring they are evenly sized for uniform cooking.

Season the Cauliflower:

Place the florets in a large bowl. Drizzle with olive oil and toss to coat evenly. Sprinkle garlic powder, onion powder, salt, and black pepper over the florets. Toss again to ensure the seasoning is evenly distributed.

Arrange on Baking Sheet:

Spread the florets in a single layer on the prepared baking sheet. Avoid overcrowding, as this can cause steaming instead of roasting.

Roast the Cauliflower:

Place the baking sheet in the preheated oven. Roast for 20-25 minutes, flipping the florets halfway through for even browning. The cauliflower should be golden brown and crispy on the edges when done.
