Ingredients You’ll Need
Here’s the lineup to make authentic-tasting Mongolian beef at home.
For the Beef
- 1 ½ pounds flank steak, thinly sliced against the grain
- ¼ cup cornstarch (for coating)
- ½ teaspoon baking soda (optional, for extra tender beef)
- 2 tablespoons vegetable oil (for frying)
For the Sauce
- ½ cup soy sauce (low sodium recommended)
- ½ cup brown sugar, packed
- ¼ cup water
- 3 garlic cloves, minced
- 1 tablespoon fresh ginger, grated
- 1–2 teaspoons red chili flakes (optional, for heat)
For Finishing
- 6 green onions, sliced (white parts and green parts separated)
- 1 tablespoon sesame oil
- White rice, for serving
Ingredient Notes:
- Flank steak is the classic choice for Mongolian beef—it’s lean but tender when sliced thin. Sirloin or skirt steak also work well.
- Cornstarch is the secret to that crisp, golden brown sear.
- Brown sugar balances the salty soy sauce with just the right sweetness.
Ingredient Substitutions
- Flank steak: Swap with sirloin, skirt steak, or thinly sliced chicken breast.
- Brown sugar: Honey or maple syrup works, but will slightly change the flavor.
- Soy sauce: Use tamari for gluten-free or coconut aminos for lower sodium.
- Vegetable oil: Peanut oil or canola oil are great high-heat options.
- Red chili flakes: Substitute with fresh chili or leave out for a milder version.
How to Make Mongolian Beef Recipe
Follow these easy steps, and you’ll have better-than-takeout beef in no time.
Step 1: Prepare the Beef
Slice flank steak thinly against the grain. Pat dry with paper towels, then toss in cornstarch (and baking soda if using). Let it rest for 10 minutes—this helps the coating stick.
Step 2: Make the Sauce
In a small bowl, whisk together soy sauce, brown sugar, water, garlic, ginger, and chili flakes. Set aside.
Step 3: Sear the Beef
Heat 2 tablespoons of oil in a large skillet or wok over medium high heat. Add the beef in a single layer (don’t overcrowd the pan). Cook 1–2 minutes per side until golden brown. Remove to a plate.
Step 4: Cook the Aromatics
In the same skillet, add garlic, ginger, and the white parts of the green onions. Stir-fry for 30 seconds until fragrant.
Step 5: Combine Everything
Pour in the sauce, bring to a simmer, then add the beef back in. Toss until the beef is coated and the sauce thickens slightly. Stir in sesame oil and the green onion tops.
Step 6: Serve
Spoon over steamed white rice, garnish with extra green onions, and enjoy!

Expert Tips & Mistakes to Avoid
- Slice beef thinly: Always cut against the grain for tender beef.
- Don’t overcrowd the pan: Fry the beef in batches for crispy edges.
- Use high heat: Stir-frying is all about quick cooking at high heat.
- Rest the beef after coating: A 10-minute rest helps the cornstarch stick.
- Adjust sweetness: Taste the sauce—add more soy for salty, or sugar for sweet.
Variations & Add-Ons
- Gluten-Free: Use tamari instead of soy sauce.
- Low-Sugar: Replace brown sugar with monk fruit sweetener or coconut sugar.
- Vegetarian Twist: Swap beef with crispy tofu or seitan.
- Veggie Boost: Add bell peppers, broccoli, or snap peas to the stir fry.
- Spicy Kick: Stir in extra red chili flakes or fresh sliced red chili.
Serving Suggestions
- Serve over steamed white rice or fried rice.
- Pair with garlic green beans or stir-fried bok choy.
- Wrap in lettuce leaves for a lighter, low-carb version.
- Add a side of egg rolls or dumplings for a complete takeout-style meal.
Storage & Reheating
- Fridge: Store leftovers in an airtight container for up to 3 days.
- Freezer: Freeze cooled beef for up to 2 months. Thaw in the fridge overnight before reheating.
- Reheat: Warm in a skillet over medium heat with a splash of water to loosen the sauce. Microwave works too, but the texture is better on the stovetop.
