Preheat oven to 375 degrees.
Defrost french fries, then use a salad spinner to remove excess moisture.
Arrange fries in a casserole dish.
Season generously with salt and pepper. Add garlic powder.
Pour in whipping cream. Fries should be fully immersed in liquid.
Sprinkle with cheese. Then add parsley and more salt and pepper, if desired.
Cover with lightly greased aluminum foil and bake for 1 hour or until cheese is golden brown.
