Preheat oven to 450F
Scrub and wash, but don't peel the potatoes (you can peel if you want).
Cut into 1/8" slices, only 3/4 from top - use chopsticks as a cutting guide.
Place cut-side-up on a greased baking sheet (or dish).
Brush each potato with melted butter, sprinkle salt&pepper.
Bake for 50 minutes, brush with butter after 20 and 40 minutes.
Whisk the cheese and bread crumbs together.
When the potatoes start to spread apart, sprinkle the cheese mixture on top, and top with a dash of paprika.
Bake another 20-30 minutes (until tender).
