Cheesy Scalloped Potatoes

Why I Love This Recipe
This is another recipe I picked up when we lived in New Orleans. It's a great version of scalloped potatoes that seems to be a favorite of everyone who's tried it.
Ingredients You'll Need
1/2 lb. Cheddar Cheese
1/4 C. margarine
1/2 tsp. pepper
4 T. flour
2 C. milk
1 tsp. salt
5 medium potatoes, unpeeled
Directions
Shred cheese, set aside. In two qt. saucepan, melt margarine over low heat. Blend in flour. Add milk all at once. Cook, stirring constantly until slightly thickened. Add cheese, salt and pepper. Cook until cheese melts. Remove from heat. Spread half of the sauce in the bottom of a shallow 2-1/2 qt. baking dish. Using food processor, thinly slice potatoes and onions. Arrange, alternating layers. Top with remaining cheese sauce, spreading evenly. Bake at 350 degrees for one hour or until potatoes are done. Serves 6-8.
