If adding bacon, spinach, pancetta or other add ins, add them now.
Carefully crack 2 eggs into each cap (if you can only fit one, only add one).
Sprinkle with salt and pepper.
Place in the oven and bake for 15-25 minutes or until the whites are opaque and set. The yolks will be runny when the whites are set but you can cook for longer if you do not want runny yolks.
