Creating Baked Cauliflower Parmesan is straightforward when you follow these simple steps:

1. Preheat your oven to 425°F (220°C) and lightly grease a baking dish with olive oil.
2. In a large bowl, combine the cauliflower florets with olive oil, garlic powder, Italian seasoning, salt, and pepper. Toss well to ensure all pieces are coated.
3. Transfer the cauliflower to the baking dish, spreading it in a single layer.
4. Bake in the preheated oven for about 20 minutes until the cauliflower is tender and starting to brown.
5. While the cauliflower is baking, whisk the eggs in a separate bowl and set aside.
6. In another bowl, mix together the bread crumbs and half of the grated Parmesan cheese.
7. After 20 minutes, remove the baking dish from the oven. Pour the beaten eggs evenly over the baked cauliflower, ensuring every piece is covered.
8. Sprinkle the breadcrumb mixture over the cauliflower, followed by the remaining Parmesan and mozzarella cheeses.
9. Return the dish to the oven and bake for an additional 10-15 minutes, or until the cheese is melted and golden brown.
10. Remove from the oven and let it cool for a few minutes before serving. Garnish with freshly chopped parsley if desired.

These easy-to-follow steps will guide you to create a delightful Baked Cauliflower Parmesan that impresses both in presentation and taste.
