Thinly slice turnips. I used a mandolin.
Melt 3 tbsp. butter. Whisk in about 3 tbsp. flour until smooth and cook for a couple of minutes. Slowly stir in about 1- 1 1/2 cups of milk. Season with salt and pepper. Cook until thick and bubbly. Pour over turnips. Top with bread crumbs and bake at 350* for about 35 minutes. Enjoy!
