Preparation Steps

• Preheat oven to 375º F.
• Spread onion rings out in a 9x13-inch baking dish, keeping rings and layers intact, then drizzle with olive oil and season generously with salt and pepper.
• Place baking dish in oven and roast for 15 minutes, or until softened.
• Remove onions from oven and raise temperature to 450º F.
• Combine heavy cream, wine, butter, garlic powder and cayenne in a medium saucepan over medium heat and cook until butter is melted and bubbles form on the outside edge of cream.
• Remove mixture from heat, then pour over pre-roasted onions, sprinkling parmesan cheese over all the onions.
• Top baking dish with aluminum foil and bake for another 20 minutes. Remove foil and cook for another 5-10 minutes, or until onions are caramelized and cheese is golden brown.
• Remove dish from oven and serve hot. Enjoy!
