Heat a medium non-stick skillet on medium to low heat.
Carefully crack the eggs into a bowl.
When the butter is melted and slightly bubbly, gently pour in the eggs into the pan.
Sprinkle the eggs with salt and pepper. Cook until the whites start to set.
Turn the heat up to medium high and flip the eggs over. This is most easily done with a large turner spatula under most of the egg and a small rubber spatula under the rest.
Let the egg cook for a few more minutes - the longer it cooks the less runny the yolk will be.
Gently tip the eggs out of the non-stick pan onto a plate to avoid breaking them.
Notes
This recipe can, of course, be doubled, or tripled, or made as big as you'd like. I do find it easier to make no more than 4 eggs at a time in one skillet.
