Ingredients
4 russet potatoes, sliced into 1/4 inch slices
1 onion, sliced into rings
salt and pepper to taste
3 tablespoons butter
3 tablespoons all-purpose flour
1/2 teaspoon salt
2 cups milk
1 1/2 cups shredded Cheddar cheese
Directions
Preheat oven to 400 degrees F (200 degrees C). Butter a 1 quart casserole dish.
Layer 1/2 of the potatoes into bottom of the prepared casserole dish. Top with the onion slices, and add the remaining potatoes. Season with salt and pepper to taste.
In a medium-size saucepan, melt butter over medium heat. Mix in the flour and salt, and stir constantly with a whisk for one minute. Stir in milk. Cook until mixture has thickened. Stir in cheese all at once, and continue stirring until melted, about 30 to 60 seconds. Pour cheese over the potatoes, and cover the dish with aluminum foil.
Bake 1 1/2 hours in the preheated oven.
I promise you will impress when you serve this. My only notes on this recipe to you would be to grate the cheese yourself instead of buying the shredded cheese (I think it's just so much more flavorful that way). I also use sharp or extra sharp cheese. My second recommendation to you would be to use vidalia onions, especially this time of year when they're in season. I get fresh ones at the farmer's market every weekend and they are so sweet and good. Enjoy y'all!
