The primary ingredient in a French omelet is eggs. Typically, two to three eggs are whisked together and cooked gently in a non-stick pan with butter. The goal is to achieve a soft and creamy texture, without browning the eggs. A classic French omelet is usually folded into a tri-fold shape and may be filled with various ingredients like herbs, cheese, or vegetables, but the emphasis is on the richness of the eggs themselves. This iconic dish showcases the skill of both cooking and presentation, reflecting the importance of simplicity and technique in French culinary tradition.
