Recipe Information
Ingredients
- 450 grams pearl onions
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 cup whole milk
- 1 cup heavy cream
- 0.5 teaspoons garlic powder
- 0.5 teaspoons onion powder
- 0.25 teaspoons ground black pepper
- 1 teaspoon kosher salt
- 1.5 cups Parmesan cheese, grated
- 0.5 cup breadcrumbs
- 1 tablespoon olive oil
- 2 tablespoons fresh parsley, chopped (optional, for garnish)
Instructions
Preheat the oven to 375°F (190°C).
Bring a pot of water to a boil. Add the pearl onions and blanch for 1-2 minutes until the skins loosen. Drain and cool under cold water, then peel the onions.
In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1–2 minutes until slightly golden, stirring constantly.
Slowly pour in the milk and cream while whisking continuously to avoid lumps. Bring the mixture to a simmer, stirring frequently, until it thickens into a smooth sauce, about 3–5 minutes.
Stir in garlic powder, onion powder, black pepper, salt, and 1 cup of grated Parmesan cheese. Mix until the cheese has melted into the sauce, then remove from heat.
Place the peeled pearl onions in a greased 9x9 inch (23x23 cm) baking dish. Pour the cheese sauce evenly over the onions, making sure they are fully coated.
In a small bowl, mix the breadcrumbs with the remaining 0.5 cup of Parmesan cheese and olive oil. Sprinkle the breadcrumb mixture over the top of the onions.
Bake the dish in the preheated oven for 25–30 minutes or until the top is golden and bubbling.
Let cool for 5 minutes before serving. Garnish with fresh parsley if desired.
