Leach Scalloped Potatoes - cooking recipe

Ingredients

5 tablespoons butter
5 tablespoons flour
1/2 teaspoon salt
1/4 teaspoon pepper
4 cups milk
2 lbs Velveeta cheese
6 large potatoes
1 large onion

Preparation

Melt butter in pan, add flour, salt & pepper and stir till blended for about 1 minute.
Add milk and stir till smooth. Cut up velveeta into thumb sized chunks and put in milk mixture. Stir till cheese has melted. Be sure to scrape bottom, it can stick easy towards the end.
Meanwhile - peel and slice potatoes (using a mandolin is great). Also peel and slice the onions.
Layer a 13.x9x2 pan potatoes, onions, (I usually add a sprinkle of salt & pepper), then another layer of potatoes & onions, then end with a final layer of potatoes. Pour sauce over and put in oven.
Bake in 325 degree oven for 90 minutes (or till potatoes are soft when poked with a fork). Enjoy!
