Gather the ingredients.
In a bowl, season the shrimp with salt and pepper. Set aside.
Next, heat up a medium pan with cooking oil (about 1/4 inch of oil) over medium heat. While you wait for the oil to heat up, untangle and separate the noodles. The noodles will likely come in small bundles, so you'll want to separate them and make sure none of the strands are stuck together.
Test the oil by putting a small strand in the oil. It should sizzle and begin to turn brown. Make sure it's not so hot that the noodle turns dark too quickly. When it's ready, take half of the noodles (4 ounces) and put a thin layer of noodles into the pan.
Cook 2-3 minutes on one side, then carefully flip with a spatula. Fry the noodles until the noodles become crispy. Take out of the pan and repeat with the other half of the noodles.
Next, make the sauce. Combine chicken stock, oyster sauce, soy sauce, pepper, and corn starch in a container and stir with a whisk.
Pour this mixture into a pot and heat over medium-high heat. Let it boil and thicken. It should have the consistency of a thin gravy.
Next, you'll cook your vegetables in the sauce. Start with root vegetables (like carrots). Let it cook for a few minutes before adding leafy vegetables. Do not overcook the vegetables, they will generally take about 4-7 minutes to cook.
Lastly, add the reserved shrimp. They will only take about 3 minutes to cook. Give everything a stir until the shrimp turn opaque and turn off the heat.
Time to plate! Place the fried chow mein noodles on a plate. Evenly divide the sauce with vegetables and shrimp and pour it over the chow mein noodles. Serve immediately and enjoy!
