4) Melt 3 tablespoons of the butter in a large skillet over medium heat.
5) Whisk in the flour and cook for 20 seconds but do not let the flour brown.

8) Melt 2 tablespoons of the butter in a medium skillet set over low heat.
9) Add the onion and cook until sweet, about 15 minutes, stirring frequently.

15) Sprinkle with 2 tablespoons of the vermouth, then spoon half the white béchamel over the top, spreading it evenly to the edges of the dish.
