Firstly, I love cast iron skillets. I have two that my mother gave me, and I would love more. Take your skillet, whatever one you have, and lightly oil it.
Turn your burner on to medium/high to warm up the pan. When your pan is hot, crack your eggs, and drop them gently into the pan, one by one.
Next, turn the burner down as low as you possibly can, then cover with a lid to hold in the heat.
My super old cast iron skillet obviously does not have a matching lid. Something close is fine. I have even used a large plate to cover it before. Just be careful because the plate will become hot.
Once the egg whites are no longer runny, you just let the eggs continue to cook until the yolk is set to your desired doneness. Not sure if that's really a word, but I like it.
I use a knife to slice out sections of eggs for everyone. I usually figure on 2 eggs a person.
This morning I enjoyed my eggs with a mixture of potatoes, onions, chicken, and green beans. Yes, I said green beans. They are a breakfast, lunch, and dinner food here, and soooo yummy with eggs. Try chopping up fresh, french style green beans and adding them to your next omelet! Delicious!
How do you like your eggs?
