Simple Mongolian Beef: Step-by-Step Guide
Ready to create this delicious dish? Follow these straightforward steps:
Step 1: Prepare the Flank Steak
Begin by slicing the flank steak against the grain into thin strips. This will ensure that the meat remains tender during cooking.
Step 2: Coat the Beef
In a bowl, add the sliced steak and sprinkle with cornstarch. Toss the beef until it is fully coated. This will help create a crispy texture when cooked.
Step 3: Heat the Oil
In a large skillet or wok, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add the coated beef in a single layer. You may need to do this in batches to avoid overcrowding the pan.
Step 4: Cook the Beef
Cook the beef for about 2-3 minutes on each side until browned and crispy. Remove from the pan and set aside.
Step 5: Make the Sauce
In the same pan, add the remaining tablespoon of olive oil. Sauté the minced garlic and grated ginger for about 30 seconds until fragrant.
Step 6: Combine the Ingredients
Add the brown sugar, soy sauce, water, and crushed red pepper flakes (if using) to the pan. Stir well and bring the mixture to a gentle simmer.
Step 7: Return the Beef
Once the sauce is simmering, return the cooked beef to the pan along with the scallions. Toss everything together to ensure the beef is coated in the sauce.
Step 8: Serve and Enjoy
Cook for an additional 2-3 minutes, allowing the sauce to thicken slightly. Serve your Simple Mongolian Beef over a bed of rice or with your favorite vegetables, and enjoy!
Substitutions by Category
If you’re missing an ingredient or have specific preferences, here are some easy substitutions you can make:

- Cornstarch: Arrowroot powder can be used as an alternative thickener.
- Brown Sugar: Coconut sugar or maple syrup can be substituted for a different sweetness profile.
- Low Sodium Soy Sauce: Tamari or coconut aminos work well for a gluten-free option.
Missteps & Fixes
Even the best cooks make mistakes! Here are some common missteps and how to fix them:
- Overcooked Beef: If your beef turns out tough, make sure to slice it thinly and cook it quickly over high heat next time.
- Sauce Too Thick: If your sauce thickens too much, simply add a splash of water to reach your desired consistency.
- Too Sweet: If the sauce is too sweet for your liking, add a splash of vinegar or lime juice to balance the flavors.
