Au Gratin Potatoes

Ingredients:

• 4 russet potatoes, sliced into 1/4 inch slices
  
• 1 onion, sliced into rings
  
• 3 Tbsp butter
  
• 1/2 tsp salt
  
• 3 Tbsp all purpose flour
  
• 2 cups milk
  
• 1 1/2 cups shredded cheddar cheese
  
• salt and pepper to taste
  

Preheat oven to 400° F.
Butter a 1 quart casserole dish and set aside.

Layer 1/2 of the potatoes in the bottom of the prepared casserole dish, top with onion. Add the remaining potatoes on top and salt and pepper to taste.

To make cheese sauce:
Melt butter in a medium sized saucepan over a medium heat. Add the flour and salt. Stir constantly with a whisk for a minute and then add milk, stirring constantly with the whisk as well until all lumps are gone.
Continue to cook over medium heat until it is thickened and hot throughout. Add the cheese all at once, continuing to stir until all the cheese is melted.

Pour the cheese sauce over the potatoes and cover the dish with tin foil.
Bake in a 400°F oven for 1 1/2 hours or until potatoes are very soft.
