however many potatoes you want to cook
thinly sliced garlic cloves
extra-virgin olive oil
salt and pepper
Thinly slice each washed and scrubbed potato almost to the bottom. Do not cut all the way through. Stick pieces of garlic in between the slices (I just sprinkled with garlic powder). Drop small bits of butter over potatoes (I just rubbed some softened butter all over with a fork). Drizzle olive oil all over. Bake at 425F for 40 minutes or until potatoes are cooked through.
Note: If you go the easy route, as I did, with the garlic powder, make sure you get it down in between the slices. I kind of pushed the potatoes up from the bottom side to fan the pieces apart so the spices could get down in the cracks.
