Potatoes Au Gratin

This dish is so tasty and easy, I really don’t understand why most people have only had it in restaurants or from one of those Betty Crocker boxes. This makes a tasty side dish for 4-5 people and is scalable if need be.




5-7 Medium to large Russet potatoes ( I usually use 1.5 potatoes per person and have left overs that are yummy)
3 Tbs Butter
3 Tbs Flour
1.5 cups of milk
1..5 cups shredded sharp Cheddar cheese (you can use about any cheese but I like cheddar)
1/2 large Spanish onion
Salt and Pepper to taste


  1. Preheat oven to 400 degrees
  2. Thinly slice 1/8-1/4 inch thick) potatoes
  3. Thinly slice 1/4 in thick onion
  4. In a fairly shallow baking dish, layer potatoes about 1/2 way full followed by onion rings, then add the remainder of potatoes until the dish is full.
  5. In a shallow frying pan on medium heat, melt the butter
  6. Add flour and whisk until bubbly yellow and thick
  7. Whisk in milk and keep stirring until you notice it just start to thicken and bubble
  8. Using a spoon, stir in the grated cheese until completely melted (40-60 seconds
  9. Remove from heat and pour or spoon over potatoes in the dish.
  10. Shake the dish to get the thick liquid to settle down into the lower layers
  11. Place baking dish in the middle of the middle rack of the over and cook for 1 hour to 1 hour and twenty minutes until cheese coating is browned and potatoes are soft.
  12. Remove from over and let rest for 10 ,minutes and serve with main course.
