01 - Whisk together the eggs, milk, salt, and white pepper in a large bowl until smooth and well combined.
02 - Add bean sprouts, carrots, green onions, mushrooms, bell pepper, and your choice of protein to the egg mixture. Stir thoroughly to distribute ingredients evenly.
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 pan for each patty. Gently flatten to create even thickness. Fry 2–3 patties simultaneously, adjusting for pan size.
05 - Cook each side for 2–3 minutes until golden brown and crispy edges form. Flip carefully using a spatula and cook the opposite side. Transfer cooked patties to a paper towel–lined plate. Repeat with remaining mixture, adding additional oil as needed.
06 - Combine chicken broth, soy sauce, oyster sauce (if using), sesame oil, and white pepper in a small saucepan. Bring to a gentle simmer over medium heat.
07 - Mix cornstarch with cold water in a small bowl to create a smooth slurry. Stir the slurry into the simmering sauce and continue cooking for 1–2 minutes until the gravy thickens to desired consistency.
08 - Arrange crispy Egg Foo Young patties on serving plates. Drizzle generously with the hot savory gravy and serve immediately while crisp.
