Roasted Parmesan Creamed Onions Ingredients
For the Onions
• Vidalia or Walla Walla onions – These sweet varieties provide the ideal flavor; Texas sweet onions can work as substitutes if needed.
• Extra-virgin olive oil – This adds a lovely richness and helps with the roasting process; melted butter is a great alternative for a different taste.
• Salt and freshly ground black pepper – Essential for enhancing the dish’s overall flavor; feel free to adjust these to suit your palate.
For the Cream Sauce
• Heavy cream – This is key for achieving that luscious texture; use half-and-half for a lighter version, but it will slightly alter the richness.
• Dry white wine – It adds depth and acidity; for a non-alcoholic option, vegetable broth is a fantastic substitute.
• Freshly grated Parmesan cheese – This adds a savory, salty finish that completes the dish; nutritional yeast can be a dairy-free alternative, though the texture will differ.

How to Make Roasted Parmesan Creamed Onions
-
Preheat your oven to 375°F (190°C). This step is essential to start roasting those onions and release their natural sweetness.
-
Slice the onions into ¼ inch thick rounds and arrange them on a lined baking sheet. Drizzle with olive oil, then season them generously with salt and freshly ground black pepper. Roast for 15 minutes or until they begin to soften.
-
Combine heavy cream and dry white wine in a saucepan over medium heat. Heat gently until simmering, then remove from heat. Pay attention to keep it from boiling; you want a smooth texture for the sauce!
-
Increase the oven temperature to 450°F (232°C) after roasting your onions. This higher heat will help create that delicious caramelization on the onions as they bake with the cream sauce.
-
Transfer the roasted onions into a shallow baking dish, pouring the warm cream mixture evenly over them. Next, sprinkle a generous layer of freshly grated Parmesan cheese on top for that irresistible cheesy finish.
-
Cover the baking dish with foil and bake for 20 minutes. Remove the foil and continue baking for an additional 5 minutes until the onions are caramelized and bubbly, creating a beautiful golden crust.
Optional: Add a sprinkle of fresh herbs, like thyme, before serving for an extra burst of flavor.
