Mom's Mongolian Beef
What is Mongolian Beef?
Mongolian beef is a Chinese-American dish of thinly sliced flank steak that's coated, fried until crisp, then tossed in a glossy sweet and savory soy sauce glaze. This is my mom's version.
I hate frying… but this was worth it 🥵 one of my favorite new dishes that my mom makes for us when we visit!


Mom's Mongolian Beef
Ingredients
Marinade
- 1 lb beef flank steak
- 1 egg white
- 1 tablespoon soy sauce
- ½ tablespoon garlic powder
- ½ tablespoon onion powder
- black pepper
- 2 tablespoon cornstarch
Sauce
- ½ tablespoon vinegar
- 2 tablespoon sugar
- 2 tablespoon soy sauce
- 4 tablespoon oyster sauce
- ½ tablespoon sesame oil
- 1 tablespoon @abcsauces dark soy sauce
- black pepper
- ¼ white onion sliced thick
- 2 slices ginger
- 5 dried Thai peppers
- 2 green onions sliced into 2" pieces
- Cooking oil
Instructions
- Slice your beef across the grain into ¼" thick pieces. Marinate with egg white, 1 tablespoon soy sauce, ½ tablespoon garlic powder, ½ tablespoon onion powder and black pepper. Marinate in the fridge for at least 30 minutes. Take out of fridge at least 30 mins prior to cooking.
- In a separate bowl, combine all the ingredients listed for the sauce. Taste and adjust to your liking.
- Add enough oil to your wok to cover the bottom of the pan. Turn on heat at medium high and wait until hot. While waiting, place your marinated meat in a zip lock bag along with 2 tablespoon cornstarch. Gently shake so meat is covered evenly with the cornstarch.
- Once oil is hot, gently fry small batches of the meat so they are crispy on each side. Do not overcrowd. Approximately 2 minutes per side. Remove and lay on a plate with paper towel. Repeat until all meat is fried. Add additional oil as needed while cooking each batch.
- Once all the meat is cooked, remove excess oil from the wok - leaving only about 2 tbsp. Over medium high heat, sauté your sliced ginger, white onion, and dried Thai peppers for 45 seconds. Add back your fried meat slices. Add ¾ of your sauce mixture and combine well. Cook for an additional 45 seconds. Taste and add remainder of sauce if needed.
- Add your sliced green onions and turn off the heat. Serve with a bowl of rice. Enjoy!!
