Omelette sound like a straightforward type of food. But there are plenty of ways to veer off and there are certain fundamentals of omelettes that are worth knowing!
Preheat a skillet on medium with a splash of olive oil.I use a pretty well seasoned cast iron pan to cook eggs, so I don't add any more than a spritz of oil. You may need upwards of a teaspoon for other types of pans, though.Use just enough so that your eggs don't stick.
Meanwhile, crack eggs into a bowl and whisk until fluffy.
Add eggs to the pan and reduce heat to low.It should sizzle a bit when you add the eggs, but shouldn't immediately deep fry. If it cooks too quickly, remove from heat and gradually reheat until low again.
Add toppings evenly across the eggs and add the lid.
Cook covered until barely set, about 5-10 minutes.The goal is to achieve a golden brown on the bottom of the eggs, cooked through the center, while still slightly runny on thee top. Depending on your stove and type of skillet, you may need to turn the temperature down if they're cooking too quickly or up if they're taking too long.
With a large spatula, gently fold one half of the omelette over to make a half circle.If it wasn't entirely set, some egg may drain out as you do this. If that happens, you can add the lid and continue to cook until set. Flip to the other side if it begins to brown too much.
Add any additional uncooked toppings and sprinkle with a dash of salt and pepper.
