How to Make 30 Minute Mongolian Beef
Step 1: Prepare the Beef
Slice flank steak into thin strips against the grain. Toss the beef in cornstarch until fully coated. Shake off any excess and let it sit for 10 minutes to help tenderize.
Step 2: Make the Sauce
In a small bowl, whisk together soy sauce, water, brown sugar, garlic, ginger, and red pepper flakes (if using). Set aside.
Step 3: Sear the Beef
Heat 1 tablespoon of oil in a large skillet or wok over medium-high heat. Add half of the beef in a single layer and sear for 1–2 minutes per side until browned and crispy. Remove and repeat with remaining beef, adding more oil as needed.
Step 4: Combine and Simmer
Reduce heat to medium. Add the sauce mixture to the skillet and bring to a simmer. Return all cooked beef to the skillet and toss to coat. Let simmer for 2–3 minutes until the sauce thickens and clings to the beef.
Step 5: Serve
Top with sliced green onions and serve hot over rice, noodles, or steamed vegetables.

Tips and Variations
Use Chicken Instead
Swap the beef with thinly sliced chicken breast or thigh for a different protein.
Make It Spicier
Add more chili flakes or a spoonful of sriracha to the sauce.
Veggie Boost
Add sautéed bell peppers, broccoli, or snap peas to the skillet before returning the beef.
Low Carb Option
Serve over cauliflower rice or zucchini noodles.
Double the Sauce
If you like your stir-fries extra saucy, double the sauce ingredients and simmer longer to thicken.
Storage and Reheating
Refrigerator: Store leftovers in an airtight container for up to 4 days.
Freezer: Cool completely and store in freezer-safe bags or containers for up to 2 months.
Reheat: Warm in a skillet over low heat or microwave in 30-second intervals until heated through.
Why This Recipe Works
The cornstarch not only gives the beef a crispy exterior but also helps thicken the sauce to that perfect sticky consistency. Searing the beef in batches ensures it browns properly without steaming. The sauce, with its balance of soy, sugar, garlic, and ginger, clings beautifully to the meat and tastes even better the next day.

Ingredients
Method
- Prep the Beef:
- Toss the thinly sliced beef in cornstarch until evenly coated. Let it sit for 5–10 minutes to help it crisp when cooked.
- Sear the Beef:
- Heat oil in a large skillet or wok over medium-high heat. Add beef in a single layer (in batches if needed) and sear for 1–2 minutes per side until browned and just cooked. Remove to a plate.
- Make the Sauce:
- In the same pan, add a little more oil if needed. Sauté garlic and ginger for 30 seconds until fragrant. Stir in soy sauce, brown sugar, water, and hoisin (if using). Bring to a simmer and cook for 2–3 minutes until slightly thickened.
- Combine:
- Return beef to the skillet and toss to coat in the sauce. Simmer for 2–3 more minutes until the sauce is glossy and clings to the beef. Stir in green onions and remove from heat.
- Serve:
- Serve over steamed rice or noodles. Garnish with more green onions or red pepper flakes for added heat.
Notes
- For crispy beef: Use a very hot pan and don’t overcrowd it when searing.
- Add vegetables: Stir in steamed broccoli or snap peas during the final simmer for a balanced meal.
- Sweetness level: Adjust brown sugar to your taste—reduce slightly for a more savory finish.
- Storage: Leftovers keep well for up to 3 days in the fridge. Reheat in a skillet for best texture.
