Instructions

Prepare the Onions: Peel the onions and trim the tops. Hollow out the center carefully to create a cavity for the filling.

Bake the Onions Initially: Place onions in a baking dish, nestling them into a bed of rock salt to keep them stable. Roast until tender but still holding their shape.

Make the Creamy Onion Mixture: In a pan, melt butter over medium heat. Add flour and cook briefly. Stir in white wine, bay leaf, salt, and pepper. Cook until the mixture thickens slightly. Remove the bay leaf before using.

Make the Béchamel Sauce: In a saucepan, melt butter, whisk in flour, then gradually add warmed milk. Stir constantly until thickened. Remove from heat and fold in grated parmesan cheese.

Combine Filling: Mix the creamy onion mixture with a portion of the béchamel until well incorporated. Taste and adjust seasoning.

Stuff the Onions: Spoon the creamy filling into the hollowed onions. Make a small indentation at the top for the egg yolk.

Add Egg Yolks and Truffles: Carefully place an egg yolk on top of each filled onion. Add truffle shavings if using.

Bake Until Golden: Return the onions to the oven and bake gently until the egg yolks are set but still soft, and the tops are lightly golden.

Serve Warm: Serve immediately with crispy bread to scoop up every bit of the creamy, luxurious filling.
