Creating Baked Vidalia Onions is quite simple. Follow these steps for a successful dish:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Onions: Peel the Vidalia onions and cut off the top. Hollow out the center using a spoon, leaving about half an inch of the onion intact.
3. Mix the Filling: In a bowl, combine the breadcrumbs, garlic powder, thyme, salt, pepper, and half of the Parmesan cheese.
4. Add Olive Oil: Drizzle the olive oil into the breadcrumb mixture and stir until well combined.
5. Stuff the Onions: Fill each hollowed-out onion with the breadcrumb mixture, pressing gently to pack it in.
6. Top with Cheese: Sprinkle the remaining Parmesan cheese on top of the stuffed onions.
7. Place in Baking Dish: Arrange the stuffed onions in a baking dish and drizzle a little more olive oil over them.
8. Cover with Foil: Cover the baking dish with aluminum foil to trap steam and ensure even cooking.
9. Bake: Bake in the preheated oven for 30 minutes, then remove the foil and bake for an additional 10 minutes until the tops are golden and crispy.
10. Cool and Serve: Allow the onions to cool slightly before serving. Garnish with fresh parsley if desired.
