Step 1

Heat the butter in a 10-inch nonstick skillet over medium-low heat. Cook until butter just begins to brown.

Step 2

Add the cold mashed potatoes. Spread evenly into pan. Cook for about three minutes until the bottom browns. Turn the mashed potatoes with a rubber spatula. Repeat until the potatoes are spotted and golden brown. This takes about 10 minutes. Season with salt and pepper to taste. Before serving, top as desired. (optional)
