Thinly slice turnips. I used a mandolin.
Layer turnips in a baking dish, overlapping a bit. Next lay slices of cheese. I use swiss and think the flavor is great, but use what you have (and like.)
Repeat with turnips and cheese, ending with turnips. Next make a white sauce
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!
