🧅 Ingredients & Their Purpose

Each ingredient in this recipe serves a critical role in building bold, balanced flavors:

Large Sweet Onions (4–5, peeled and sliced ½ inch thick)

These are the star of the show. Their natural sweetness intensifies in the oven, creating an irresistible base for the cream sauce.

3 tbsp Extra Virgin Olive Oil

Adds depth and richness, helping the onions roast to tender, caramelized perfection while enhancing flavor.

1 cup Heavy Cream

The creamy backbone of the dish. It creates a luscious, velvety sauce that soaks into the onions.

¼ cup White Wine

Adds brightness and acidity, cutting through the richness of the cream and enhancing complexity.

¼ cup Grated Parmesan Cheese

Brings umami and nuttiness. As it melts and browns, it forms a golden crust that’s downright addictive.

Salt and Pepper (to taste)

Essential for seasoning. Salt draws out the onions’ moisture and sweetness, while pepper adds a subtle kick.

🔥 Step-by-Step Instructions: Roasted Parmesan Creamed Onions

Step 1: Preheat & Prep

Preheat your oven to 375°F (190°C).

Peel and slice your sweet onions into ½-inch thick rounds, being careful to keep the layers intact. Do not separate the rings.

Step 2: First Roast

Line a baking dish with parchment paper.

Place the intact onion slices into the dish and drizzle generously with olive oil.

Season with salt and pepper.

Roast for 15–20 minutes, or until the edges start to soften and turn golden.

Step 3: Prepare the Cream Sauce

While the onions roast, add the heavy cream and white wine to a saucepan over medium heat.

Simmer gently until small bubbles appear around the edges. Do not let it boil—this prevents curdling and keeps the sauce smooth.

Step 4: Add the Sauce

Remove onions from the oven.

Carefully transfer them to a clean baking dish, still keeping the rings together.

Slowly pour the warm cream mixture over the onions.

Sprinkle evenly with grated Parmesan cheese.

Step 5: Cover & Bake

Cover the dish tightly with foil and return to the oven.

Bake for 20 minutes, allowing the onions to absorb the sauce and soften further.

Step 6: Final Roast

Remove the foil and bake for an additional 5–10 minutes, until the top is bubbling and golden brown.

Let rest for 5 minutes before serving. The sauce will thicken beautifully.

Simmer the cream slowly. Avoid boiling to keep the sauce silky.

Don’t skip the foil step—it helps the onions steam and become fork-tender before finishing with that golden crust.
