How to Make Roasted Parmesan Creamed Onions

Step 1: Warm Up the Oven

Crank your oven to a toasty 375°F (190°C), getting ready for some onion magic.

Step 2: Prepare the Onion Canvas

• Spread onion slices on a parchment-lined baking sheet
• Drizzle olive oil generously
• Sprinkle salt and pepper to wake up the flavors

Slide the sheet into the oven and let the onions roast for 15 minutes until they start to soften and turn golden.

Step 3: Create the Creamy Elixir

In a small saucepan, swirl together heavy cream and white wine. Let the mixture simmer gently until tiny bubbles dance around the edges.

Remove from heat and set aside.

Step 4: Boost the Heat

Bump up the oven temperature to a scorching 450°F (232°C) to intensify the roasting process.

Step 5: Layer the Flavors

Transfer the roasted onions to a shallow baking dish, keeping their beautiful rings intact. Pour the cream and wine mixture evenly over the onions.

Generously shower Parmesan cheese on top of each slice.

Step 6: Final Roasting Flourish

Cover the dish with aluminum foil and return to the oven for 20 minutes.

Then uncover and bake for an additional 5 minutes until the onions turn a gorgeous caramelized brown with crispy edges.

Cooking Tips to Perfect Roasted Parmesan Creamed Onions

• Opt for sweet onions like Vidalia for a milder, more delicate flavor that melts beautifully when roasted.
• Slice onions uniformly to ensure even cooking and consistent texture across each serving.
• Use freshly grated Parmesan cheese instead of pre-shredded varieties for richer, more authentic taste and better melting properties.
• Line baking sheet with parchment paper to prevent sticking and make cleanup easier, ensuring perfectly roasted onions without mess.
• Lower the heat if onions start browning too quickly, protecting them from burning while maintaining a soft, creamy interior.

Flavor Swaps to Enhance Roasted Parmesan Creamed Onions

• Vegan Creamy Onion Bake: Swap heavy cream with coconut milk and use nutritional yeast instead of Parmesan cheese for a dairy-free alternative.
• Low-Carb Roasted Onion Gratin: Replace white wine with vegetable broth and use almond flour as a lighter topping alternative to Parmesan.
• Herb-Infused Onion Casserole: Add fresh thyme, rosemary, and sage to the cream mixture for an aromatic herb-enhanced version of the original recipe.
• Mediterranean Onion Medley: Incorporate crumbled feta cheese, sprinkle with za'atar seasoning, and use olive oil infused with garlic for a Mediterranean-inspired variation.

Pairings to Serve With Roasted Parmesan Creamed Onions

• Select a bright, acidic Sauvignon Blanc or Pinot Grigio to cut through the richness of the creamy Parmesan onions and refresh the palate.
• Serve the onions alongside a simply roasted chicken seasoned with rosemary and thyme, creating a harmonious blend of savory flavors that enhance the dish's delicate creaminess.
• Use a rustic, hearty sourdough to soak up the delicious Parmesan cream sauce, adding textural contrast and providing a perfect vehicle for enjoying every last drop of the luxurious onion preparation.

Storage Tips to Preserve Roasted Parmesan Creamed Onions

• Store leftovers in an airtight container for up to 3-4 days. Cool the dish completely before sealing to prevent moisture buildup and maintain texture.
• Transfer onions to a freezer-safe container, ensuring minimal air exposure. Properly stored, they can last up to 2 months. Wrap tightly with plastic wrap and aluminum foil for best preservation.
• Preheat oven to 350°F. Place onions in an oven-safe dish, cover with foil to prevent drying, and warm for 10-15 minutes until heated through. Remove foil for the last 3-5 minutes to restore crispiness.

FAQs

• Can I use different types of onions for this recipe?

Yes, you can use sweet onions like Vidalia or red onions. Each type will bring a slightly different flavor profile to the dish.

You can replace white wine with chicken broth or vegetable stock to maintain the liquid’s consistency and add depth to the flavor.
