Ingredients

• 4 large yellow onions
• 2 tablespoons unsalted butter
• 2 tablespoons all-purpose flour
• 1.5 cups whole milk
• 0.5 cups heavy cream
• 0.5 cups grated Parmesan cheese
• 0.5 cups grated Gruyere cheese
• 1 teaspoons salt
• 0.5 teaspoons ground black pepper
• 0.25 teaspoons ground nutmeg
• 0.5 cups panko breadcrumbs
• 1 teaspoons olive oil
• 2 tablespoons fresh parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Peel the onions and trim the tops and bottoms to create a flat surface. Slice each onion in half horizontally.

Step 3

Place the onion halves cut-side down in a pot of boiling salted water. Boil for 8-10 minutes until slightly tender but still holding their shape. Drain and set aside.

Step 4

In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.

Step 5

Gradually whisk in the milk and heavy cream, ensuring no lumps form. Cook and stir until the sauce thickens, about 3-4 minutes.

Step 6

Remove the saucepan from heat and stir in the Parmesan cheese, Gruyere cheese, salt, black pepper, and nutmeg. Mix until the cheese has melted and the sauce is smooth.

Step 7

Arrange the boiled onion halves cut-side up in a single layer in a baking dish.

Step 8

Pour the cheese sauce evenly over the onions, making sure they are fully covered.

Step 9

In a small bowl, combine the panko breadcrumbs with the olive oil. Sprinkle the breadcrumb mixture evenly over the top of the dish.

Step 10

Bake in the preheated oven for 25-30 minutes, or until the top is golden and bubbling.

Step 11

Remove from the oven and let the dish rest for 5 minutes before serving.

Step 12

Garnish with fresh parsley if desired. Serve warm and enjoy!
