Easy Mongolian Beef
This Mongolian Beef recipe features thin flank steak strips coated in cornstarch and quickly seared for a tender, slightly crispy texture. The beef is then tossed in a sauce made from tamari soy sauce, coconut sugar, molasses, sesame oil, ginger, and garlic, offering a rich, savory, slightly sweet flavor with subtle molasses depth. It is finished with sliced green onions for a fresh bite. This approach balances quick cooking for tender beef with a thickened, flavorful sauce.
Ingredients
For the Mongolian Beef
- 2 tablespoons avocado oil or another high-heat oil
- 1 pound flank steak
- ¼ cup cornstarch
- 3 green onions thinly sliced on a diagonal
For the sauce
- ½ cup tamari soy sauce
- ⅓ cup coconut sugar
- ¼ cup water
- 2 teaspoons sesame oil
- 1 teaspoon blackstrap molasses
- 1 teaspoon ginger fresh, minced
- 4 garlic finely chopped, cloves
Instructions
- Prep the sauce. In a medium bowl, stir together the soy sauce, sugar, water, sesame oil, molasses, ginger, and garlic. Set aside.
- Slice the steak. Slice the steak in half lengthwise, then slice crosswise against the grain into thin strips.
- Prep the steak. In a mixing bowl, toss the sliced flank steak with the cornstarch, shake off any excess, and then set aside on a separate plate.
- Cook the steak. Heat the oil in a large skillet or wok over medium-high heat. Add the steak to the wok and cook in small batches, for about 30 to 60 seconds on each side, until browned. Remove the cooked steak to a plate, and repeat this process until all of the steak is cooked. If needed, add a splash of more oil to the wok in between batches.
- Simmer the sauce. Reduce the heat to medium, add the sauce, and let it simmer for 4 to 5 minutes, stirring occasionally, until slightly thickened.
- Finish the Mongolian beef. Add the steak back to the wok, and stir with the sauce for 1 to 2 minutes, to reduce the sauce further and fully coat the meat. Sprinkle the sliced green onions on top, and give it one final stir before serving.
Notes
- Add red pepper flakes at the end for a spicy variation.
- Coconut sugar and molasses can be substituted with brown sugar if unavailable.
- Store cooled leftovers in an airtight container in the fridge for up to 4 days.
- Freeze portions in freezer-safe containers or bags for up to 3 months for convenient reheating.
