Step-by-Step Method:
-
Roast the Onions:
Preheat your oven to 400°F (200°C). Toss the peeled onions with olive oil, salt, and pepper. Spread them on a baking sheet in a single layer and roast for 25–30 minutes, stirring halfway through, until the onions are golden brown and tender. -
Prepare the Cream Sauce:
In a skillet over medium heat, melt the butter. Add minced garlic and sauté for 30 seconds until fragrant. Pour in the heavy cream and bring to a gentle simmer. Reduce the heat and stir in the grated Parmesan cheese until melted and smooth. Season with salt, pepper, and a pinch of nutmeg if desired. -
Combine and Simmer:
Add the roasted onions to the cream sauce, tossing gently to coat each piece. Allow the mixture to simmer for 3–5 minutes, letting the flavors meld together and the sauce thicken slightly. -
Serve:
Transfer the creamed onions to a serving dish and garnish with freshly chopped parsley for a pop of color and freshness. Serve immediately alongside roasted meats, poultry, or as part of a vegetable medley.
Tips for Perfect Roasted Parmesan Creamed Onions:
-
Choose Your Onions Wisely: Pearl onions roast beautifully for a bite-sized version, but yellow onions work well when cut into halves or quarters.
-
Avoid Overcooking Garlic: Garlic can burn quickly; sauté just until fragrant to avoid bitterness.
-
Cheese Variations: For a deeper flavor, mix in a small amount of Gruyère or Asiago cheese with the Parmesan.
-
Make Ahead: Roast the onions ahead of time and reheat them in the cream sauce just before serving to save time.
Roasted Parmesan Creamed Onions are the perfect marriage of sweet, caramelized onions and rich, cheesy cream. They bring sophistication and comfort to any plate and are sure to impress family and guests alike with minimal effort.
