These similar dishes share some of the same cooking methods and ingredients, but they are two entirely different dishes. Pad Thai is a Thai recipe that includes rice noodles, bean sprouts, carrots, onions, protein, and often a sprinkle of crushed peanuts. In contrast, Lo Mein is a Chinese recipe using Chinese egg noodles made from wheat flour and eggs. Furthermore, the sauces of these two similar recipes are different– Lo Mein primarily uses sesame oil, and Pad Thai traditionally includes tamarind sauce.
