According to the founding legend of the annual giant Easter omelette of Bessières, Haute-Garonne, when Napoleon Bonaparte and his army were traveling through southern France, they decided to rest for the night near the town of Bessières. Napoleon feasted on an omelette prepared by a local innkeeper, and thought it was a culinary delight. He then ordered the townspeople to gather all the eggs in the village and to prepare a huge omelette for his army the next day.
On March 19, 1994, the largest omelette (128.5 m2, 1,383 sq ft) in the world at the time was made with 160,000 eggs in Yokohama, Japan, but was subsequently overtaken by another, weighing 2,950 kilograms (6,500 lb), made by the Canadian Lung Association at the Brockville Memorial Centre in Brockville, Ontario, Canada, on May 11, 2002. In turn, that record was surpassed on August 11, 2012, by an omelette cooked by the Ferreira do Zêzere City Council in Santarém, Portugal. This record-breaking omelette weighed 6,466 kg (14,255 lb), and required 145,000 eggs and a 10.3-metre (34 ft) diameter pan.
A Denver omelette, also known as a Southwest omelette or Western omelette, is an omelette filled with diced ham, onions, and green bell peppers, though there are many variations on fillings. Often served in the Southwestern United States, this omelette sometimes has a topping of cheese and a side dish of hash browns or fried potatoes.
The French omelette is smoothly and briskly cooked in an extremely hot pan specially made for the purpose. The technique relies on clarified butter (to ensure a high smoke point) in relatively great ratio to the eggs (prevents sticking and cooks the eggs more quickly). Good with just salt and pepper, this omelette is often flavored with tomato and finely chopped herbs (often fines herbes or tarragon, chervil, parsley and chives) or chopped onions.
A Greek omeleta consists of pan-fried or sautéed vegetables, pastas, or leftovers over which beaten eggs are poured to act as a binder. It is then cooked with a plate over the top, flipped onto the plate, and slid back in to cook the other side. Unlike many of the other omelette styles, the Greek omeleta is more often used to showcase leftovers or fresh ingredients rather than to emphasise the eggs.
A frittata is a kind of open-faced Italian omelette that can contain cheese, vegetables, or even leftover pasta. Frittata are cooked slowly. Except for the cooking oil, all ingredients are fully mixed with the eggs before cooking starts.
In Japan, tamagoyaki is a traditional omelette in which eggs are beaten with mirin, soy sauce, bonito flakes, sugar and water, and cooked in a special rectangular frying pan. The omelette is cooked by frying a thin layer of egg mixture and then rolling it up quickly with a pair of chopsticks to form a sausage shape in one end of the pan. Another thin layer of egg is then added to the bottom of the pan and is again rolled, with the original rolled, cooked egg at the centre, over to the other end of the pan. This is repeated until all the egg has been used up, resulting in a dense cylindrical omelette containing many thin layers. This is then squeezed into a rectangular or circular cross-section using a sushi mat, and sliced into segments for serving. Omelette (pronounced omuretsu) can mean a Western omelette. Omurice (from the English words "omelette" and "rice") is an omelette filled with rice and usually served with a large amount of tomato ketchup. Omu-soba is an omelette with yakisoba as its filling.
In Thai cuisine, a traditional omelette is called khai chiao (khai meaning "egg", and chiao meaning oil-fried), in which the beaten egg mixture and a small quantity of fish sauce is deep fried in a wok filled with 1-2 cups of vegetable oil and served over steamed rice. The dish is usually served with Sriracha sauce and cilantro. A variation on this dish is khai chiao songkhrueang, where the plain egg omelette is served together with a stir-fry of meat and vegetables. Yet another type of Thai omelette is khai yat sai, literally "eggs filled with stuffing".
