Add frozen potatoes into the muffin molds. Completely line muffin mold with potatoes, all the way to the rim because potatoes will shrink when cooked. The muffin mold should be almost completely full of potatoes, except for an indent section in the middle for the egg. Spray surface of potatoes with pam spray.
Cook in oven for about 15-20 minutes until the outer potatoes turn brown and are crisp. Reduce oven temperature to 350°F. If using large or extra large eggs, remove half of the egg white to use for whatever else you please. Place the egg yolk and remaining egg white in the center of the nest, making sure not to overflow the nest with egg white.
Cook for an additional 5-8 minutes until egg white is cooked and egg yolk reaches desired doneness.
