Cooking Eggs in Cast Iron
A well-seasoned cast iron skillet is the most reliable tool for eggs if you treat it with respect. It retains heat far longer than thin metal, allowing for a consistent, steady set that translates to even browning and proper coagulation of the whites.
Mastering the slide
The secret isn't the pan's age; it is the temperature management. Cold oil on a cold pan will lead to an egg that welds itself to the iron.

Heat testing
Before adding your fat, flick a few droplets of water into the skillet. If they bead up and skate across the surface rather than hissing and evaporating instantly, your pan is ready.
The method.
Preheat the skillet
Set your burner to medium-low. Let the pan sit for 3 to 5 minutes. Do not rush this; the iron needs to heat through completely to avoid hot spots.
Add the fat
Drop in the butter. Once it melts and foams, swirl it to coat the entire bottom and up the edges slightly. If using oil, wait until it shimmers and moves like water.
Crack the eggs
Crack the eggs into a bowl first, then slide them gently into the pan. This prevents broken yolks and shell fragments from hitting the hot iron.
Set the whites
Let the eggs sit undisturbed. You will see the whites transition from transparent to opaque. If the edges begin to crisp too aggressively, pull the pan off the heat.
The release
Slide your spatula under the whites. If you feel resistance, wait 30 seconds. A properly cooked egg in a hot pan will release its own grip on the iron once the proteins set.
Other turns to take.
Basted eggs
After the whites set, add a teaspoon of water to the edge of the pan and cover immediately with a lid to steam the tops of the yolks.
When it doesn't go to plan.
Always crack eggs into a bowl first to ensure the yolk is intact.
If the eggs stick, use your spatula to lift a corner and pour a tiny amount of butter underneath to help release the bond.
Wipe the skillet out with a paper towel while warm and apply a light layer of oil before storing.

Can I use soap to clean my skillet after cooking eggs?
Yes. Modern dish soap is gentle enough that it won't strip a well-seasoned layer of polymerized oil. The bigger risk is leaving the pan wet, which leads to rust.
