Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
Prepare the Coating
In a bowl, combine breadcrumbs, Parmesan (if using), garlic powder, paprika, onion powder, salt, and pepper.
Coat the Cauliflower
Dip each cauliflower floret into the beaten eggs (or milk alternative), then roll in the breadcrumb mixture until well coated.
Bake Until Crispy
Arrange florets on the baking sheet in a single layer. Drizzle lightly with olive oil.
Bake for 25–30 minutes, flipping halfway through, until golden brown and crispy.
Serve
Remove from the oven and let cool slightly before serving.
