Atomic Hash Browns
Heat a 12-inch nonstick skillet over medium heat.
Set a baking sheet or a large plate over the skillet and carefully invert the potatoes onto the baking sheet. Add the remaining butter and oil to the skillet and slide the potatoes back in, un-cooked side down, and cook until golden and crispy on the second side as well, 4 to 5 minutes.
Slide onto a cutting board and cut into wedges to serve.
