Ingredients You’ll Need

- 1/4 cup cornstarch: Coating the beef in cornstarch helps give it a crispy outer layer when seared.
- 1/3 cup water: This helps create a smooth sauce when mixed with other ingredients.
- 1/4 cup low-sodium soy sauce: A key ingredient for the savory base of the sauce; low-sodium ensures you can control the saltiness.
- 1/2 cup brown sugar, packed: The sweetness of brown sugar balances the savory soy sauce, creating that signature flavor.
- 2 teaspoons cornstarch: This will help thicken the sauce for a nice glossy finish.
- 1/4 cup vegetable oil: A neutral oil perfect for frying; it withstands high heat well.
- 2 garlic cloves, minced: Fresh garlic adds an aromatic punch that complements the beef.
- 1 tablespoon minced ginger: Ginger provides a warm, spicy note that brightens the dish.
- 4 green onions, cut into one-inch pieces: Using both the white and green parts adds color and fresh flavor.
How to Make Mongolian Beef So Good You’ll Skip Takeout Forever
Coat the Beef: In a large bowl, toss the 1 pound flank steak with 1/4 cup cornstarch until well coated. This will create that lovely crisp texture we’re after. Set aside while you prepare the sauce.
Mix the Sauce: In a small bowl, whisk together 1/3 cup water, 1/4 cup low-sodium soy sauce, 1/2 cup brown sugar, and 2 teaspoons cornstarch until smooth. Set this mixture aside as well; it will become your luscious sauce.
Cook the Flank Steak: In a large skillet over medium heat, add 1/4 cup vegetable oil. Once shimmering, add the coated beef in small batches. Fry for about 3 to 5 minutes per batch or until browned and crispy. Remove from the pan and transfer to a plate, covering with foil to keep warm. Drain all but 1 tablespoon of oil from the pan.
Sauté the Aromatics: Add 2 minced garlic cloves and 1 tablespoon minced ginger to the same skillet, along with the whites of the 4 green onions. Sauté until fragrant, being cautious not to let the garlic burn.
Thicken the Sauce: Pour the prepared sauce into the skillet, scraping up any delicious browned bits from the bottom. Bring to a simmer, and cook until the sauce thickens, around 1 minute. This is where the magic happens!
Combine the Ingredients: Return the cooked beef to the skillet, tossing to coat in the thickened sauce. Serve immediately, garnished with the greens of the green onions, over a bed of hot rice.
Storing & Reheating
Leftovers can be kept covered in the fridge for up to 3 days. For optimal freshness, store in an airtight container. If you want to freeze it, place the dish in a freezer-safe container, and it will last for up to 3 months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight and reheat on the stovetop over medium heat, adding a splash of water if the sauce has thickened too much.
Chef’s Helpful Tips
- Avoid overcrowding the pan while frying the beef, as this can result in steaming instead of searing.
- If cooking for a crowd, consider doubling the recipe; it’s easy to make in larger batches.
- For a spice kick, add a teaspoon of red pepper flakes to the sauce for an extra layer of flavor.
- Use day-old rice, if you have it, as it holds up better than freshly cooked rice when combined with the saucy beef.
- Feel free to add bell peppers or broccoli for a veggie boost.
This Mongolian beef is packed with flavors that will whisk you away to your favorite Asian restaurant, all from the comfort of your home kitchen. Its balance of sweet, savory, and aromatic components can turn dinner into a special occasion, leaving you with that warm and cozy feeling. Don’t shy away from experimenting; adjust the sauce to your taste or incorporate your favorite veggies.
