Mongolian Beef is a classic dish from Asian menus around the world. This recipe gives you the tips and tricks to make the authentic dish in the comfort of your own kitchen. So yummy!
Place the cut beef into a large ziplock baggie or baking dish. Pour the cornstarch mixture and water/oil over the beef. Seal the baggie and use your hands to massage the beef into the cornstarch and water/oil. Place in the fridge for 1 hour, or up to 24 hours.
Prep the Sauce and Stir-Fry
Combine all of the sauce ingredients into a medium-sized bowl and whisk together until blended.
¼ cup soy sauce, ¼ cup brown sugar, 3 tablespoon oyster sauce, 3 tablespoon hoisin sauce, 3 tablespoon Thai sweet chili sauce, ½ teaspoon red pepper flakes, 1 teaspoon ginger, 1 clove garlic, 1 teaspoon cornstarch
Heat the oil (¼ cup) in your wok (or skillet) over high heat. Add the garlic and cook for about 30 seconds, until just starting to turn golden.
¼ cup vegetable oil, 3 cloves garlic
Carefully add the beef and stir with a wooden spoon until the pinkness is almost gone, about 4 minutes.
Add the onion, red and green peppers, and cook, stirring frequently, for another 2 minutes.
1 cup onion, ½ green bell pepper, ½ red bell pepper
Transfer the sauce to the wok, and stir continuously for 2 minutes, or until the sauce has thickened slightly. Turn off the heat and stir in half of the sliced green onions.
4 green onions
Serve at once with steamed rice or noodles on the side and extra sliced scallions and sesame seeds for garnish.

Notes
If you can't find flank steak, then use skirt steak, or any kind of strip steak (such as New York or Kansas City). If using strip steak, place the meat in the freezer for about 15 minutes, and then slice it into slivers. The beef can sit in the baggie with the cornstarch and baking soda for up to 24 hours in the fridge. We love using Thai Sweet Chili Sauce for the sauce, but if you can't find it, then use any brand of chili sauce. Just remember, chili sauce typically has more heat (spice) than Thai Sweet Chili Sauce, so you may want to use only 1 or 2 tablespoon of chili sauce if you are substituting it for Thai Sweet Chili Sauce. SUPER IMPORTANT: Make sure you have all of your ingredients prepped and ready to go before you start preparing the dish. It all comes together very fast, and you won't have time to stop and prep and ingredients once you get started cooking. This dish is wonderful served over steamed rice or cellophane noodles.
