Instructions

Preheat and Prepare Onions: Preheat your oven to 400°F (200°C). Toss the peeled and halved onions with olive oil, salt, and black pepper. Arrange them cut side up in a greased or parchment-lined baking dish.
Roast Onions: Roast the onions in the oven for 25 to 30 minutes, until they are tender and beginning to caramelize, which enhances their natural sweetness and flavor.
Make Cream Sauce: While the onions roast, melt butter in a saucepan over medium heat. Stir in the flour and cook for about 1 minute to form a roux. Slowly whisk in the heavy cream, garlic powder, thyme, and a pinch of salt and pepper. Simmer the sauce for 4 to 5 minutes, stirring frequently until it thickens.
Add Parmesan: Stir in the grated Parmesan cheese into the sauce until it melts completely and the mixture is smooth and creamy.
Combine and Bake: Pour the creamy Parmesan sauce evenly over the roasted onions. Sprinkle additional Parmesan cheese on top. Return the dish to the oven and bake for another 15 to 20 minutes until the sauce is bubbly and golden on top.
Serve: Allow the dish to cool slightly before serving. Garnish with chopped fresh parsley if desired for a fresh, herby touch.

Notes

For added depth of flavor, consider adding a splash of white wine or chicken broth to the cream sauce.
This dish pairs wonderfully with roast meats such as turkey or beef, making it ideal for holiday meals.
Ensure onions are evenly halved to roast uniformly.
Use fresh Parmesan cheese for best melting and flavor results.
