01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or a silicone baking mat.
02 - In a shallow bowl, whisk together the eggs and milk until well combined.
03 - In a separate bowl, combine panko breadcrumbs, Parmesan cheese, garlic powder, smoked paprika, salt, and black pepper.
04 - Dip each cauliflower floret into the egg mixture, allowing excess to drip off, then coat thoroughly with the breadcrumb mixture. Place coated florets in a single layer on the prepared baking sheet.
05 - Lightly drizzle or brush the melted butter over the coated cauliflower for extra crispiness.
06 - Bake for 25–30 minutes, flipping the florets halfway through, until golden brown and crisp.
07 - Remove from the oven and sprinkle with fresh parsley and extra Parmesan if desired. Serve immediately with marinara or ranch dipping sauce.
