Directions

1. Wash potatoes and slice as thin as possible, about 1/4" to 1/8". Cook in microwave until just soft, about 2 minutes per potato.
2. Melt 2 tablespoons of butter in frying pan, add 1/2 cup of chopped onion, and cook over medium heat for 1 minute, add two spoonfuls flour. Stir until it becomes a paste.
3. Add one cup milk. Stir constantly until it thickens, about 3 minutes. Remove from pan and set aside.
4. Layer potatoes, cheddar cheese and bacon bits until pan is full. Pour sauce over potato layers and cook for 20 minutes at 450°F or until all potatoes are soft, in an oven safe pan.
