Ingredients

• 4 cups peeled pearl onions (fresh or frozen)
• 4 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 0.5 cup heavy cream
• 0.5 cup grated Parmesan cheese
• 1 cup shredded Gruyère cheese (or Swiss cheese)
• 0.25 teaspoons ground nutmeg
• 1.5 teaspoons salt
• 0.5 teaspoons ground black pepper
• 0.75 cup panko breadcrumbs
• 1 tablespoon olive oil
• 2 tablespoons chopped fresh parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

If using fresh pearl onions, blanch them in boiling water for 2 minutes, then transfer to an ice bath. Peel the onions by trimming the root end and gently squeezing until the skin slips off. If using frozen pearl onions, thaw them and pat dry with paper towels.

Step 3

In a large saucepan, melt 3 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, until the mixture is pale and bubbly.

Step 4

Slowly whisk in the milk and heavy cream, cooking until the sauce thickens and begins to bubble, about 4-5 minutes.

Step 5

Stir in the grated Parmesan cheese, half of the shredded Gruyère cheese, nutmeg, 1 teaspoon of salt, and black pepper. Remove the sauce from heat and set aside.

Step 6

In a large baking dish (approximately 9x13 inches), arrange the peeled pearl onions in an even layer.

Step 7

Pour the prepared cheese sauce evenly over the onions, ensuring all are coated.

Step 8

In a small bowl, combine the panko breadcrumbs with 1 tablespoon of olive oil, the remaining shredded Gruyère cheese, and 1/2 teaspoon of salt. Mix well and sprinkle the breadcrumb mixture evenly over the onions and sauce.

Step 9

Dot the top of the dish with the remaining 1 tablespoon of butter, broken into small pieces.

Step 10

Bake the dish in the preheated oven for 30-35 minutes, or until the top is golden and bubbling.

Step 11

Let the Creamed Onion Bake cool slightly before serving. Garnish with fresh parsley if desired.
