Making Creamy Baked Onions with Asiago Cheese is a straightforward process. Follow these steps for a delicious outcome:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Onions: Peel the onions and slice them in half. Remove the core, creating a small well in each half.
3. Sauté Onions: In a large skillet, heat olive oil over medium heat. Add the onion halves cut-side down and sauté for about 5-7 minutes until they begin to soften.
4. Mix Cream and Cheese: In a bowl, combine heavy cream, grated Asiago cheese, garlic powder, salt, pepper, and thyme. Stir until well mixed.
5. Fill Onions: Place the sautéed onion halves in a baking dish. Pour the cream and cheese mixture into the wells of the onions, filling them generously.
6. Add Breadcrumbs: If using, sprinkle breadcrumbs over the top of the filled onions for added texture and crunch.
7. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Then remove the foil and bake for an additional 10-15 minutes, or until the cheese is golden and bubbly.
8. Garnish: Once baked, remove from the oven and allow to cool slightly. Garnish with fresh parsley before serving.
9. Serve Warm: Transfer to a serving platter and enjoy the rich, creamy goodness!
