Prepare Ingredients: Crack 3 large eggs into a mixing bowl. Add a pinch of salt and freshly ground black pepper. Whisk thoroughly until the mixture is smooth.
Heat the Pan: Place an 8-inch nonstick skillet over medium-low heat. Add 1 teaspoon of unsalted butter and let it melt, coating the pan evenly.
Cook the Eggs: Pour the whisked eggs into the skillet. Stir gently and continuously with a silicone spatula, ensuring the eggs cook evenly.
Form the Omelet: As the eggs begin to set but are still slightly runny, stop stirring. Tilt the pan to let the eggs cover the bottom evenly.
Fold the Omelet: Gently fold the omelet in thirds using the spatula. Slide it onto a plate.
Garnish: Sprinkle fresh chives or parsley on top before serving.
