Creating Creamy Baked Onions is simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Onions: Peel the onions and slice them in half from top to bottom. Then, remove the inner layers to create onion “cups.”
3. Sauté Onions: In a large skillet, melt the butter over medium heat. Add the onion halves and sauté for 5-7 minutes until they start to soften.
4. Season: Sprinkle garlic powder, salt, black pepper, and thyme (if using) over the onions, stirring to combine.
5. Add Cream: Pour the heavy cream into the skillet, allowing it to simmer for 2-3 minutes, ensuring the onions are coated.
6. Layer with Cheese: Place the sautéed onion halves in a baking dish. Spoon the creamy mixture over each onion and top with grated cheese.
7. Bake: Cover the baking dish with foil and bake for 30 minutes. Then, remove the foil and bake for an additional 15 minutes until the cheese is golden and bubbly.
8. Garnish: Once baked, remove from the oven and let cool slightly. Garnish with chopped fresh parsley before serving.
9. Serve: Enjoy warm as a delicious side dish!
