Directions

Preheat oven to 400 degrees with rack in bottom third. Heat milk in a saucepan over medium heat until hot, about 5 minutes. Melt butter in another saucepan over medium heat; add flour, whisk to combine, and cook 2 minutes, stirring occasionally. Add 1 1/2 tablespoons thyme, then gradually whisk in milk. Simmer bechamel 2 minutes, whisking. Remove from heat, and add 1 teaspoon salt and 1/2 teaspoon pepper.

Remove from oven. Preheat broiler. Spread bechamel on top, and sprinkle with remaining cheese. Broil until golden brown and bubbling, 6 to 7 minutes. Remove from oven; garnish with pepper and remaining thyme. Let sit 10 minutes before cutting.
