Ingredients
1½ pounds pearl onions, fresh or frozen and thawed
2 tablespoons olive oil
Salt and black pepper to taste
For the Parmesan Cream Sauce
2 tablespoons butter
1 cup heavy cream
¾ cup freshly grated Parmesan cheese
½ teaspoon garlic powder
½ teaspoon dried thyme
Optional garnish of chopped fresh parsley and extra Parmesan
Instructions Step by Step
Preheat your oven to 400°F 200°C.
Place the pearl onions on a baking sheet, drizzle with olive oil, and season with salt and black pepper. Toss gently to coat evenly.
Roast for 25 to 30 minutes, stirring once halfway through, until the onions are tender and lightly golden.
While the onions roast, prepare the sauce.
In a medium saucepan over medium heat, melt the butter.
Add the heavy cream, Parmesan cheese, garlic powder, and dried thyme.
Whisk gently and allow the sauce to simmer for 5 to 7 minutes, stirring often, until slightly thickened and smooth.
Add the roasted onions to the Parmesan sauce.
Stir gently to coat the onions completely.
Simmer together for about 5 minutes to allow the flavors to blend.
Remove from heat and garnish with fresh parsley and extra Parmesan if desired. Serve warm.
Variations
Use sliced yellow or sweet onions instead of pearl onions if preferred.
Add a splash of white wine to the sauce for extra depth.
For a protein-rich version, stir in cooked chicken or mushrooms.
Use Pecorino Romano or Gruyère in place of Parmesan for a different flavor profile.
For a dairy-free option, substitute coconut cream and plant-based Parmesan.
Tips for the Best Results
Roasting the onions first is key for maximum flavor.
