- Whisk eggs well to incorporate air, which helps create a light and fluffy texture.
- Add a splash of heavy cream for extra softness and richness (optional but recommended).
- Cook on medium-low heat to avoid browning too quickly and to keep the eggs tender.
- Avoid overfilling the omelet so it folds easily without breaking.
- Use a non-stick pan or a well-seasoned skillet for easy flipping.
- Cheese choice matters—use good melting cheeses like cheddar, mozzarella, or Swiss.
- Season at the right time—lightly season the eggs before cooking and adjust after if needed.
