Ingredients
• ½ cup diced white onion
• 4 tablespoons butter ( ½ stick)
• 4 tablespoons flour
• 2 ½ cups of heavy cream
• 2 cups grated Gruyere Cheese• Salt and Pepper
• 6 Potatoes, washed (not peeled), sliced thin
Directions
Preheat oven to 350* F. On stovetop cook the onion in butter until soft, add flour and cook for 2 minutes to cook the flour taste out. Whisk in heavy cream and continue to whisk until thick and creamy. Remove from heat and add 1 ¾ cups of Gruyere, stirring until melted. In a pie dish, arrange potatoes in a beautiful round layer, sprinkle with salt and pepper and cover with a third of the sauce. Push the ingredients down and repeat this step for a second layer. Once the second layer is complete, push the potatoes down again to get all the juices and cheese to spread through out the layers. Finally, lay down the third layer and pour the rest of the sauce over them. Bake covered for 30-45 minutes or until potatoes are tender. Heat the broiler and let the potatoes rest for 2 minutes. Then top with the rest of the Gruyere and put under broiler until Gruyere is brown and bubbly. Be careful, these will be hot!!
