01 - Whisk together the eggs, milk, salt, and white pepper in a large bowl until smooth and fully incorporated.
02 - Add the bean sprouts, carrots, green onions, mushrooms, bell pepper, and diced protein to the egg mixture. Stir until evenly distributed.
03 - Heat 2–3 tablespoons of vegetable oil in a large nonstick skillet or wok over medium-high heat until shimmering.
04 - Scoop approximately 1/2 cup of the egg mixture into the hot pan for each patty. Gently flatten to create even rounds. Fry 2–3 patties at a time, depending on pan size.
05 - Cook each side for 2–3 minutes until golden brown and crispy edges form. Flip carefully with a spatula and cook the opposite side. Transfer to a paper towel–lined plate. Repeat with remaining mixture, adding more oil as needed.
06 - Combine the chicken broth, soy sauce, oyster sauce, sesame oil, and white pepper in a small saucepan. Bring to a simmer over medium heat.
07 - Whisk cornstarch with cold water in a small bowl until smooth to create a slurry. Stir the slurry into the simmering sauce and cook for 1–2 minutes until thickened and glossy.
08 - Arrange the crispy Egg Foo Young patties on serving plates. Drizzle generously with the hot gravy and serve immediately.
