Preheat oven to 400 degrees.  Scrub potatoes clean and remove spots—no need to peel them.  Cut them into similar-sized chunks, leaving the small ones whole, if possible.  The smaller the chunks, the quicker they roast.

Place potatoes in a 9 x 13 baking dish.  Sprinkle sea salt evenly over the potatoes then drizzle with melted butter or olive oil.*  Toss with your hands to coat evenly.

Bake about 20 minutes.  Stir.  Bake another 15-20 minutes, until tender and golden brown.

*Garlic powder, rosemary, parsley, black pepper may also be added to potatoes.
