Roasted Parmesan Creamed Onions

Introduction and Origin

Roasted Parmesan Creamed Onions are a rich, savory side dish that turns humble onions into a decadent delight. With roots in classic French and American comfort cuisine, this dish blends caramelized, oven-roasted onions with a creamy, cheesy sauce for a side that’s both rustic and refined. It’s a perfect addition to holiday tables, steak dinners, or cozy autumn meals.

Cultural Significance

Creamed vegetables, particularly onions, have long been associated with traditional holiday feasts in the United States and Europe. Their creamy, mellow flavor complements roasted meats and adds warmth to the winter table. The use of Parmesan adds an Italian touch, balancing earthiness with umami depth. It’s a dish that bridges the gap between nostalgic comfort and gourmet appeal.

Ingredients Quantity

6 medium yellow or sweet onions, peeled and halved
2 tablespoons olive oil
½ teaspoon salt
¼ teaspoon black pepper
2 tablespoons butter
2 tablespoons all-purpose flour
1½ cups heavy cream or half-and-half
½ cup grated Parmesan cheese
¼ teaspoon garlic powder (optional)
¼ teaspoon nutmeg (optional, for depth)
2 tablespoons chopped fresh parsley (for garnish)

Optional Additions

A pinch of cayenne for mild heat
Gruyère or Fontina cheese mixed with Parmesan for added richness
A dash of white wine in the cream sauce
Crispy bacon bits sprinkled on top before serving

Tips for Success

Roast onions cut side up to help them caramelize and soak in flavor.
Don’t rush roasting — low and slow brings out sweetness.
Use freshly grated Parmesan for best melt and taste.
Warm the cream before adding to the roux to prevent clumping.
Broil for a golden top after baking, if desired.

Instructions

Preheat oven to 375°F (190°C).
Place halved onions in a baking dish, cut side up. Drizzle with olive oil, sprinkle with salt and pepper.
Roast for 35–45 minutes until golden and tender.
Meanwhile, in a saucepan over medium heat, melt butter. Whisk in flour to make a roux and cook for 1 minute.
Slowly whisk in cream, stirring constantly until thickened, about 5–7 minutes.
Stir in Parmesan cheese, garlic powder, and nutmeg (if using). Cook until cheese melts and sauce is smooth.
Pour the cream sauce over roasted onions in the baking dish.
Return to oven and bake for 10–15 minutes, until bubbly. Optional: broil for 2–3 minutes for a golden crust.
Garnish with parsley and serve warm.
