1 medium baking potato
1 teaspoon olive oil
½ teaspoon salt
2 teaspoons butter
1 pinch freshly ground black pepper
¼ cup shredded Cheddar cheese
Preheat the oven to 300 degrees F. Scrub the potato and pierce the skin several times with a knife or fork. Rub the skin with olive oil then with salt.
Place the potato in the preheated oven and bake for 90 minutes or until slightly soft and golden brown. Slice the potato down the center and serve with butter and black pepper. Sprinkle shredded Cheddar cheese over the top, if desired.
