Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it with cooking spray.
In a mixing bowl, combine the softened butter, parsley, chives, thyme, minced garlic, lemon zest, and a pinch of salt. Mix well until all ingredients are combined. Set aside.
In a large bowl, add the cauliflower florets. In a separate bowl, whisk together the eggs.
Sprinkle the flour over the cauliflower and toss to coat evenly. Then, dip each floret into the egg mixture, allowing excess to drip off.
In another bowl, mix the breadcrumbs, Parmesan cheese, garlic powder, onion powder, smoked paprika, salt, and pepper. In batches, transfer the cauliflower florets from the egg mixture to the breadcrumb mixture, ensuring they are well-coated.
Place the coated cauliflower pieces on the prepared baking sheet in a single layer. Bake for 20-25 minutes, or until golden brown and crispy, flipping halfway through for even cooking.
Once the cauliflower is crispy, remove from the oven and immediately toss the hot cauliflower bites in the prepared herb butter until nicely coated.
Transfer the herb butter crispy cauliflower bites to a serving platter and serve warm, garnished with additional chopped herbs if desired.
