Basically, it's a fancier baked potato. You have artistic license though; stuff those slices with anything you like! I used thinly sliced garlic and thyme.
Additions of choice; garlic, spices, meats, cheeses, use your imagination.
Preheat oven to 425.
Slice the potato by laying it in a wooden spoon and making close horizontal cuts, as pictured above, not cutting all the way through. If desired, insert fillings into slices. Rub outside generously with olive oil and top with salt. Bake for 1 hour or until tops are crispy and inside is cooked through.
