Au Gratin Potatoes
3 lbs potatoes
5 tablespoons butter
6 tablespoons flour (I used whole wheat flour)
4 cups milk
2 garlic cloves, crushed
2 teaspoons salt
1 dash cayenne pepper
2 cups cheddar cheese
1/3 cup parmesan cheese, grated
Preheat oven to 350°F. Boil potatoes until just tender, 20-25 minutes; drain. When cool enough to handle, peel and dice into 1/2 inch pieces.
In a large saucepan, melt butter over medium heat. Add flour; stir while cooking, 1-2 minutes. Whisk in milk and add garlic. Season with salt and cayenne pepper. Stir in cheddar cheese and all but 2 tbs parmesan cheese. Add potatoes to sauce and stir to mix evenly.
Pour into 3 qt round casserole or rectangular baking dish. Sprinkle remaining parmesan cheese over top.
Bake casserole 45 minutes or until potatoes are tender and dish is bubbling and lightly brown on top. Let stand 5 minutes before serving.
