Ingredients
4 large sweet onions (Vidalia or Walla Walla work beautifully), peeled and sliced into ½-inch rounds
3 tablespoons extra virgin olive oil
1 cup heavy cream
¼ cup dry white wine (Sauvignon Blanc or Pinot Grigio)
¼ cup grated Parmesan cheese
Salt and freshly ground black pepper, to taste
Tip: Slice onions into full rounds and keep the rings intact. This makes for a beautiful layered presentation and helps them hold shape as they roast.
Step-by-Step Instructions
Step 1: Preheat & Prepare
Preheat oven to 375°F (190°C).
Line a large baking sheet with parchment paper for easier cleanup.
Slice onions into ½-inch thick full rounds, carefully preserving the ring structure.
Lay onion slices in a single layer on the baking sheet.
Step 2: Season & First Roast
Drizzle onions with olive oil, coating them evenly.
Sprinkle with salt and pepper to taste.
Roast for 20–25 minutes, until softened and lightly golden (not fully browned yet).
This roast develops sweetness and tenderizes the onions — the first step to melting perfection.
Step 3: Make the Cream Sauce
While the onions roast:
In a small saucepan, combine:
1 cup heavy cream
¼ cup dry white wine
Bring to a gentle simmer over medium heat — small bubbles around the edges are perfect.
Do not boil. Remove from heat and let sit.
Step 4: Assemble for Final Bake
Carefully transfer the roasted onions to a deeper baking dish (8×8 or 9×13-inch works well), keeping the rounds as intact as possible.
Pour the cream sauce slowly over the onions, letting it seep through.
Sprinkle with ¼ cup Parmesan cheese (or more if desired).
Cover tightly with foil.
Step 5: Bake Again
Bake covered for 20 minutes, then uncover.
Return to the oven for another 5–10 minutes, or until:
The top is golden and bubbling.
The edges are slightly browned.
The sauce is thickened and creamy.
Serving Suggestions
Pair these Roasted Creamed Onions with:
Prime rib, roast chicken, or pork loin
Mashed potatoes or cheesy grits
Buttered green beans or sautéed kale
Spoon some of the luscious cream sauce over each serving — it’s rich, silky, and full of onion flavor.
Reheating Tip: Gently warm leftovers in the oven at 300°F until bubbling again. Avoid the microwave if you want to keep the cream from separating.
Variations & Add-Ons
Add herbs: Fresh thyme or rosemary adds an aromatic touch.
Swap cheeses: Try Gruyère, Fontina, or Asiago for deeper, nutty flavor.
Add meat: Sprinkle cooked bacon or pancetta before the final bake for a salty, smoky finish.
Make it vegetarian: Use a vegetarian-friendly Parmesan or sub with nutritional yeast for a plant-based version.
Why It’s Ideal for Older Adults
Easy to chew: Soft, melt-in-your-mouth texture.
Mild but flavorful: No harsh spices needed — just slow-roasted flavor and creaminess.
Comfort food with a refined edge: Feels nostalgic yet modern — like a cozy casserole with a restaurant twist.
Final Thoughts

With just a few ingredients and a bit of oven time, you’ll transform basic onions into something velvety, savory, and unforgettable.
