Ingredients Needed
Here’s everything you’ll need to make the best Mongolian Beef:
- 1 lb (450g) flank steak, thinly sliced against the grain
- 2 tbsp vegetable oil (or any neutral oil)
- 1/2 cup soy sauce (use gluten-free soy sauce for a gluten-free option)
- 1/4 cup brown sugar (you can substitute with honey or maple syrup for a natural sweetener)
- 1/2 cup water
- 3 cloves garlic, minced
- 1-inch piece fresh ginger, grated
- 2 green onions, sliced (for garnish)
- 1/2 tsp red pepper flakes (optional, for added spice)
- 1 tbsp cornstarch (for thickening the sauce)
Step-by-Step Instructions
- Prep the Beef: Slice the flank steak against the grain into thin strips, about 1/4 inch thick. This ensures the beef is tender when cooked.

- Cook the Beef: In a large skillet, heat 1 tablespoon of vegetable oil over medium-high heat. Add the sliced beef and cook for 2-3 minutes until browned on both sides. Remove the beef from the skillet and set aside.

- Make the Sauce: In the same skillet, add the remaining tablespoon of oil. Add minced garlic and grated ginger, cooking for 1 minute until fragrant. Pour in the soy sauce, brown sugar, and water, stirring to combine.

- Thicken the Sauce: In a small bowl, mix the cornstarch with a little water to create a slurry. Slowly add the slurry to the skillet while stirring. Let the sauce simmer for another 2-3 minutes until it thickens.
- Combine Beef and Sauce: Return the cooked beef to the skillet, stirring to coat it in the thickened sauce. Let it cook for another 2-3 minutes until the beef is fully coated and heated through.

- Garnish and Serve: Sprinkle sliced green onions and red pepper flakes (if using) on top before serving. Serve with steamed rice or noodles for a complete meal.

Recipe Tips & Variations
- Make it Spicier: Add more red pepper flakes or a dash of sriracha sauce to the sauce to give it an extra kick.
- Sweeten it Up: If you prefer a sweeter dish, increase the amount of brown sugar or substitute with honey or coconut sugar.
- Add Veggies: For a healthier twist, add sliced bell peppers, carrots, or broccoli to the dish while cooking the beef. This will add more flavor and nutrients.
- Make it Low-Carb: Use cauliflower rice instead of regular rice to make this dish low-carb and keto-friendly.
- Gluten-Free: Ensure you use gluten-free soy sauce to make this dish suitable for those with gluten sensitivities.
How to Store & Reheat
Storing: Store any leftover Mongolian Beef in an airtight container in the fridge for up to 3 days.
