Roasted Creamed Onions Recipe
Introduction
Roasted Creamed Onions offer a delightful twist on a classic side dish, combining tender, caramelized onions with a rich, creamy sauce. This comforting recipe elevates simple onions into a flavorful treat perfect for any meal.

Ingredients
- 4 large yellow or sweet onions, peeled and sliced 1/4-inch thick
- 3 tablespoons extra-virgin olive oil
- Salt & pepper, to taste
- 1 cup heavy cream
- 1/4 cup dry white wine
- 1/4 cup grated Parmesan cheese
Instructions
- Step 1: Preheat the oven to 375 degrees F. Place the sliced onions carefully onto parchment-lined baking sheets, keeping the rings intact. Drizzle with olive oil and season with salt and pepper. Roast for 15 minutes.
- Step 2: While the onions roast, combine the heavy cream and white wine in a small saucepan. Simmer gently until bubbles appear around the edges, then remove from heat and set aside.
- Step 3: Remove the onions from the oven and raise the oven temperature to 450 degrees F. Transfer the onions carefully to a shallow baking dish, keeping the rings intact. Pour the cream mixture evenly over the onions and sprinkle with Parmesan cheese.
- Step 4: Cover the baking dish with foil and return it to the oven for 20 minutes. Remove the foil and cook for an additional 5 minutes to allow the onions to brown and caramelize.
Tips & Variations
- Use sweet onions like Vidalia for a milder, sweeter flavor that complements the cream sauce.
- Substitute the dry white wine with chicken broth or vegetable stock for a non-alcoholic version.
- For extra richness, sprinkle some shredded Gruyère or mozzarella along with the Parmesan before baking.
- Serve with fresh herbs like thyme or parsley to add a fresh note to the creamy dish.
Storage
Store leftover roasted creamed onions in an airtight container in the refrigerator for up to 3 days. Reheat gently in a microwave or in a covered pan on low heat to avoid curdling the cream sauce.

FAQs
Can I make this recipe dairy-free?
Yes, you can substitute heavy cream with coconut cream or a plant-based cream alternative, and use nutritional yeast instead of Parmesan to keep it dairy-free.
What type of white wine works best?
A dry white wine such as Sauvignon Blanc or Pinot Grigio is ideal, as it adds a subtle acidity without overpowering the creaminess of the dish.

Roasted Creamed Onions Recipe

- Yield: 4 servings 1x
Description
This Roasted Creamed Onions recipe features tender onion rings roasted to perfection, smothered in a creamy, wine-infused sauce, and topped with Parmesan cheese for a rich, caramelized finish. A delightful side dish that combines roasting and baking techniques to enhance the natural sweetness of onions.
Ingredients
Ingredients
- 4 large yellow or sweet onions, peeled, sliced 1/4-inch thick
- 3 tablespoons extra-virgin olive oil
- Salt & pepper, to taste
- 1 cup heavy cream
- 1/4 cup dry white wine
- 1/4 cup grated Parmesan cheese
Instructions
- Preheat Oven and Roast Onions: Preheat your oven to 375°F (190°C). Carefully place the sliced onion rings onto parchment-lined baking sheets, keeping the rings intact. Drizzle them evenly with extra-virgin olive oil and season with salt and pepper. Roast in the oven for 15 minutes to begin softening and caramelizing the onions.
- Prepare Cream Sauce: While the onions roast, combine the heavy cream and dry white wine in a small saucepan. Heat it on the stovetop and let it simmer gently until bubbles appear around the edges, then remove from heat and set aside. This will create a flavorful creamy sauce that complements the onions.
- Increase Oven Temperature and Assemble Dish: Once the onions have roasted for 15 minutes, increase the oven temperature to 450°F (232°C). Carefully transfer the roasted onion rings to a shallow baking dish, maintaining their ring shape. Slowly pour the warm cream and wine sauce over the onions, ensuring even coverage.
- Add Cheese and Bake Covered: Sprinkle the grated Parmesan cheese evenly over the top of the onions. Cover the baking dish tightly with aluminum foil to lock in moisture and return it to the oven. Bake for an additional 20 minutes to allow the flavors to meld and the sauce to thicken.
- Finish Baking Uncovered: Remove the foil and bake uncovered for another 5 minutes. This step allows the onions to brown and caramelize further, developing a delicious golden crust on top.
Notes
- Use dry white wine such as Sauvignon Blanc or Pinot Grigio for best flavor in the cream sauce.
- Keep the onion rings intact for an attractive presentation and even cooking.
- You can substitute Parmesan cheese with Pecorino Romano for a sharper taste.
- Roasting at two different temperatures helps achieve soft, caramelized onions with a creamy topping.
- For a lighter dish, use half-and-half instead of heavy cream but expect a less rich sauce.
