Scrub potatoes. Place potato on a cutting board inbetween 2 long skewers. Cut the potato from top to bottom into thin slices. The skewers will prevent your knife from slicing through the bottom of potatoes.

Place potatoes in a greased baking dish or on a foil lined pan. Tuck bleu cheese in between slices. Brush generously with butter and drizzle with olive oil. Season with salt and pepper.

Bake at 425 degrees for 60 to 75 minutes, or until potato is cooked through and soft in the middle. Garnish with Parmesan cheese if desired.
