3-4 potatoes - thinly sliced (about 1/4 in.)
1/4 c. melted butter
1/4 c. oil
1/2-1 tsp each. salt/pepper to taste
1 tsp. garlic powder
1/4 c. grated parmesan cheese.
Preheat oven to 400.
Arrange thinly sliced potatoes in 9 x 9 pan. If you have a large family or are serving many people, this can easily be doubled and served in a 9 x 13 casserole dish.
In bowl, mix butter, oil, salt, pepper, garlic powder and parmesan cheese. Pour evenly over potatoes. Bake for 45 minutes, or until potatoes are tender, and parmesan is browned on potatoes.
