Au Gratin Potatoes
- 4-6 medium potatoes, thinly sliced
- 1 medium onion, minced
- salt, ground black pepper and red pepper to taste
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- ½ teaspoon salt
- 2 cups milk
- 1 ½ cups shredded Cheddar cheese
Directions
Gather all ingredients. Preheat the oven to 400°.
Grease a 2-quart casserole dish with butter.
Layer 1/2 of the potatoes in the bottom of the prepared casserole dish; season with salt and peppers.
Layer minced onion over top, then top with with remaining potatoes. Season again with salt and pepper.
Melt butter in a medium saucepan over medium heat. Whisk in flour and salt; cook, whisking constantly, about 1 minute. Gradually add milk, about 1/4 cup at a time, whisking well after each addition to incorporate and avoid lumps. Cook, whisking constantly, until the mixture has thickened, 3 to 5 minutes. Stir in cheese all at once, stirring constantly until melted, about a minute
Pour cheese sauce over the potatoes, and cover the dish with aluminum foil. Bake in the preheated oven until potatoes are tender and sauce is bubbly, about 1 ½ hours. Uncover for last 20 minutes. 4 servings.
They look so yummy. I love potatoes all different ways. Happy weekend,
