01 - Whisk together eggs, milk, salt, and white pepper in a large bowl until smooth and fully combined.
02 - Add bean sprouts, carrots, green onions, mushrooms, bell pepper, and protein of choice to the egg mixture. Stir until evenly distributed.
03 - Heat 2–3 tablespoons vegetable oil in a large nonstick skillet or wok over medium-high heat until shimmering.
04 - Scoop approximately 1/2 cup of egg mixture per patty into the hot pan. Gently flatten with the back of a spoon. Cook 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 transfer to a paper towel-lined plate. Add more oil as needed between batches.
06 - Combine chicken broth, soy sauce, oyster sauce, 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 slurry. Stir into the simmering broth and cook for 1–2 minutes until thickened and glossy.
08 - Plate the crispy patties hot and drizzle generously with the savory gravy. Garnish with additional green onions if desired.
