Melt 3 T. butter in a large skillet. Sauté the onions, stirring, for 5 minutes. Remove from heat.
Blanch the celery in lightly salted, boiling water for 3 minutes. Drain and refresh in cold water. Drain thoroughly and stir into the onions.
Melt 3 T. butter in a heavy saucepan and stir in the flour. Cook over medium, stirring, for 2 minutes without browning.
Whisk in the milk, whisking until mixture thickens. Season with salt and pepper and fold into the vegetable mixture. Spoon into a greased 2-quart baking dish.
