Table of Contents
Ingredients
- 4 large sweet onions (Vidalia or yellow onions work well)
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1/4 teaspoon ground nutmeg
- 1 teaspoon fresh thyme leaves (optional)
- 1/4 cup breadcrumbs (optional, for topping)
Instructions
- Preheat Oven: Preheat your oven to 400°F (200°C). Grease a 9×13-inch baking dish and set aside.
- Prepare the Onions: Peel the onions and cut them into thick slices, about 1/2-inch thick. Arrange the onion slices in a single layer in the prepared baking dish.
- Season and Roast: Drizzle the onions with olive oil and season with salt and black pepper. Roast in the preheated oven for 25-30 minutes, or until the onions are tender and starting to caramelize.
- Prepare the Cream Sauce: While the onions are roasting, in a small saucepan, heat the heavy cream over medium heat until it starts to simmer. Stir in the grated Parmesan cheese, ground nutmeg, and thyme leaves (if using). Cook, stirring continuously, until the cheese is melted and the sauce is smooth.
- Combine and Bake: Pour the cream sauce over the roasted onions, making sure they are evenly coated. If desired, sprinkle breadcrumbs over the top for added texture. Return the dish to the oven and bake for an additional 15-20 minutes, or until the sauce is bubbly and golden.
- Serve: Let the dish cool slightly before serving. Garnish with additional fresh thyme if desired.
Cook’s Notes and Tips
- Onion Type: Sweet onions like Vidalia or yellow onions work best for this recipe, as they have a natural sweetness that complements the creamy sauce.
- Cream Consistency: Be sure to simmer the cream, but avoid boiling it, as this can cause the sauce to separate.
- Breadcrumb Topping: For a crunchier topping, mix the breadcrumbs with a little melted butter before sprinkling over the onions.
Variations
- Cheesy Onions: Add 1/4 cup of shredded Gruyère or mozzarella cheese to the cream sauce for an extra cheesy flavor.
- Herbed Creamed Onions: Stir in 1 tablespoon of chopped fresh herbs, like rosemary or sage, to the cream sauce for added depth of flavor.
- Bacon Topping: Sprinkle crumbled cooked bacon over the top before the final bake for a smoky addition.
