Preparing Roasted Parmesan Creamed Onions
Roasting onions brings out their natural sweetness, making them an extraordinary accompaniment to various dishes. When you add in cream and parmesan cheese, you elevate them into an indulgent side that’s perfect for special occasions or cozy dinners. Let's take you through the steps to prepare these savory Roasted Parmesan Creamed Onions that will leave your guests raving.
Preheat the oven and prep the onions
First things first, you’ll want to preheat your oven to 375º F. This initial temperature is perfect for softening the onions and getting their natural sugars to start caramelizing. While the oven heats up, take your three sweet onions and peel them. Then, slice them thinly, ensuring they’re uniform for even cooking.
Spread the onion rings out in a 9x13-inch baking dish, keeping those delicious rings and layers intact. Drizzle with extra-virgin olive oil (don’t skimp—this adds flavor!) and season generously with kosher salt and freshly cracked pepper. Use your hands to toss the onions gently, ensuring each slice gets coated for maximum flavor.
Roast the onions to perfection
Place your baking dish in the preheated oven for about 15 minutes. This initial roasting will soften the onions and begin the caramelization process. You’ll know they’re ready when they are tender and starting to become translucent. After this, you'll want to crank up the oven to 450º F to achieve that delightful golden hue later on.
Create that creamy mixture
While your onions are roasting, it's time to whip up the creamy delight that will drench them. In a medium saucepan, combine 1 cup of heavy cream with 4 tablespoons of unsalted butter, 1 teaspoon of garlic powder, and a dash of cayenne for those who like a hint of heat (feel free to skip it if you prefer). Heat this over medium until the butter melts and bubbles form at the edges. It’s the perfect opportunity to savor that inviting aroma; who doesn’t love the smell of melting butter and garlic?
Combine and bake
Once the onions are tender, remove them from the oven and carefully pour that luxurious cream mixture over them. Sprinkle ½ cup of grated Parmesan cheese evenly on top—this will help create a beautifully rich flavor when baked. Cover the dish with aluminum foil to trap in moisture and bake for an additional 20 minutes. After that, remove the foil and let it bake for another 5-10 minutes, or until the onions are golden brown and caramelized.
Finish it off and serve
The moment of truth! Remove your exquisite Roasted Parmesan Creamed Onions from the oven, and give yourself a moment to appreciate the gorgeous golden color and the aroma wafting through your kitchen. Serve them hot, and watch as your friends and family dig in. These delightful onions are the perfect side dish for roasted meats or a hearty pasta dish.
This recipe is not just delicious; it’s simple enough for any young professional craving a comforting indulgence after a long day. Who knew onions could be such a crowd-pleaser? Enjoy every creamy, cheesy bite!
