I am a Southern girl from French heritage. If you have never tried this recipe, it's easy and always good.
Preheat oven to 425 degrees. Use a cake or quiche pan (8" wide or so) and spray with Pam. You could also butter it.
Slice potatoes very thinly. I use a mandolin, but you could do it by hand. You're looking for slices 1/8" thick. I don't bother peeling the potatoes, but if skins bother you, then by all means peel them first! You'll need at least four good size potatoes. My favorite potato to use is medium size red potatoes. I like the flavor and skin of these.
Put sliced potatoes in one layer in the bottom of pan overlapping slices. Sprinkle with salt and pepper and drizzle melted butter. Repeat for three layers. Drizzle remaining butter on the top.
Bake 45 minutes to one hour or until top is very brown and crispy. You can garnish with fresh parsley and sour cream if desired. The result is almost like a fried potato but crispier and with and awesome butter flavor.
Take a walk after dinner to get rid of the calories! Bon appetit!
