Ingredients You’ll Need
- 1 pound flank steak: This cut is lean, tender, and ideal for stir-frying. Look for steak with good marbling for the best flavor.
- 1/4 cup cornstarch: Helps to tenderize the beef while creating a lovely crust during cooking. If you don’t have this on hand, you can use all-purpose flour.
- 1/3 cup water: This balances the sauce and ensures a smooth texture.
- 1/4 cup low sodium soy sauce: A must for the savory base of the dish. Low sodium helps in controlling the saltiness.
- 1/2 cup brown sugar, packed: Adds a delightful sweetness that counters the saltiness of the soy sauce. If you prefer less sweetness, try using half the amount.
- 2 teaspoons cornstarch: This thickens the sauce for that glossy finish. Keep it on hand for ensuring a perfect texture.
- 1/4 cup vegetable oil: This is used for frying the beef until crispy. Any neutral oil like canola or peanut oil works well.
- 2 garlic cloves, minced: The aromatic flavor enhances the overall taste profile.
- 1 tablespoon minced ginger: Fresh ginger gives a wonderful warmth and depth to the dish.
- 4 green onions, cut into one-inch pieces: They add freshness and color. Be sure to separate the white and green parts to maximize flavor.
How to Make Mongolian Beef So Good You’ll Skip Takeout Forever
- Coat the Steak: In a large bowl, combine the 1 pound of flank steak with 1/4 cup of cornstarch. Toss until well-coated. Let it sit for around 10 minutes while you prepare the sauce.
- Mix the Sauce: In a small bowl, whisk together the 1/3 cup of water, 1/4 cup of low sodium soy sauce, 1/2 cup of packed brown sugar, and 2 teaspoons of cornstarch. Set this aside; it’ll be the magic that brings everything together.
- Heat the Oil: In a large skillet over medium heat, drizzle in 1/4 cup of vegetable oil. Wait until it shimmers, signaling it’s hot enough to sear the beef.
- Cook the Beef: Add the flank steak in batches, ensuring not to overcrowd the skillet. Each batch should cook for about 3 to 5 minutes or until crispy and golden. Remove the beef and transfer it to a plate, then loosely tent with foil to keep warm.
- Sauté Aromatics: Drain off all but 1 tablespoon of oil from the pan. Add in the minced garlic, minced ginger, and the whites of the green onions. Sauté until fragrant—this is usually about 30 seconds. Keep an eye on the garlic to prevent burning!
- Thicken the Sauce: Pour the previously mixed sauce into the skillet, scraping up any browned bits that cling to the pan. Bring it to a simmer and cook until the sauce thickens—this should take about 1 minute.
- Combine and Serve: Return the beef to the skillet, tossing to evenly coat it in the sauce. Garnish with the remaining green onions and serve over a bed of rice.
Storing & Reheating
Store any leftover Mongolian beef in an airtight container in the fridge for up to 3 days. For longer storage, you can freeze it for up to 3 months. When reheating, gently warm it in a skillet over low heat until heated through, which usually takes about 5-7 minutes. You might notice a slight change in texture; a splash of water during reheating can help refresh the sauce and beef.
Chef’s Helpful Tips
- Avoid overcooking the steak; it should be juicy and tender. Remove it from the skillet when it’s golden brown, and let it rest before the next step.
- Make sure to slice the flank steak against the grain. This helps tenderize the meat and make it more enjoyable to chew.
- For a kick of heat, add red pepper flakes or sliced chilies when you sauté the aromatics.
- If the sauce is too thin, ensure you’ve allowed sufficient time for it to thicken, and if needed, whisk in a bit of cornstarch mixed with water.
- Want a lighter version? Substitute the beef with thinly sliced chicken or tofu for a delicious alternative.
Every bite of this Mongolian Beef is packed with flavor, transforming a simple weeknight dinner into something special. Its sweet and savory profile is not only appealing, but it also creates a comforting experience that reminds you of your favorite takeout. I encourage you to experiment with it—maybe try adding bell peppers or snap peas for extra texture!
Cooking at home not only saves you money, but it also fills your kitchen with enticing aromas that no restaurant can quite replicate. So grab your ingredients, and let’s enjoy a homemade feast so scrumptious that takeout will be a thing of the past!

Recipe FAQs

Absolutely! If flank steak isn’t available, you could use sirloin or even skirt steak. Just ensure to slice it thinly to maintain tenderness.

While I recommend enjoying it fresh for the best texture, you can prepare the sauce and slice the steak in advance. Just cook it up right before serving for the best results.
What should I serve with this dish?
Mongolian beef is excellent served over fluffy white rice or steamed jasmine rice. It can also pair beautifully with sautéed vegetables like bell peppers or broccoli.
Can I make this recipe gluten-free?
Yes, you can easily adapt this recipe to be gluten-free by swapping out the low sodium soy sauce for tamari or coconut aminos.
