Step‑by‑Step Instructions for Mongolian Beef
Step 1: Prep Ingredients
Begin by slicing your flank steak into thin strips against the grain, which ensures tenderness. Mince around three cloves of fresh garlic and a piece of fresh ginger about the size of your thumb. Chop the green onions, separating the white and green parts, and prepare a few dried red chilies by breaking them up if you prefer more heat.
Step 2: Create Sauce
In a medium bowl, whisk together a robust mix of soy sauce, hoisin sauce, and brown sugar until the sugar dissolves. Then, fold in the minced garlic and ginger, stirring to combine the sweet and savory flavors. This aromatic sauce will be the heart of your Mongolian Beef, so set it aside once well-mixed for easy access later.
Step 3: Coat Beef
Take your sliced flank steak and toss it gently in a bowl with cornstarch, ensuring each piece is thoroughly coated. This step is crucial, as it not only tenderizes the beef but also helps achieve that desirable sear. Allow the coated beef to sit for about 10 minutes, giving the cornstarch time to adhere properly.
Step 4: Sear Beef
Heat a tablespoon of oil in a hot cast-iron skillet or wok over medium-high heat until it shimmers. Working in batches, carefully add the beef to the skillet, spreading it out without crowding. Sear for 2-3 minutes, stirring occasionally until each piece is beautifully browned and cooked through. Remove the beef and set it aside, maintaining that nice sear.
Step 5: Combine
With the beef removed, pour the prepared sauce into the hot skillet, scraping up any browned bits for added flavor. Bring it to a simmer, and allow it to thicken for about 2 minutes. Then, return all the cooked beef to the skillet and toss it quickly with the sauce until every piece is well-coated and heated through; this should take about 1-2 minutes.
Step 6: Serve
Finally, transfer your delicious Mongolian Beef onto a serving platter or directly onto individual plates. Garnish generously with the sliced green parts of the green onions and any additional chilies if desired. Serve hot over steamed rice or noodles for a complete meal that’s sure to impress your family or guests.

Mongolian Beef Recipe FAQs
How do I choose the right flank steak?
Absolutely! For the best Mongolian Beef, select a flank steak that is bright red in color with minimal dark spots. It should feel firm to the touch but not too hard. Look for a cut with a good balance of fat for flavor, but avoid pieces that are too fatty or have a strong odor.
What’s the best storage method for leftovers?
Very! Store any leftover Mongolian Beef in an airtight container in the refrigerator for up to 3 days. Allow the dish to cool to room temperature before sealing to ensure flavors are maintained. When properly stored, it’ll stay tasty and ready to reheat!
Can I freeze Mongolian Beef?
Of course! To freeze Mongolian Beef, let it cool completely, then transfer it into a freezer-safe container or zip-top freezer bag. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw in the fridge overnight before reheating.
What if my beef turns out tough?
Oh, I can help with that! If your beef turns out tough, it may be due to slicing against the grain, not enough cooking time, or not using cornstarch properly. Make sure to slice the flank steak thinly against the grain, which tenderizes the meat. Also, avoid overcrowding the skillet while searing; cook in batches for a nice crust and even cooking.
Are there any dietary considerations I should keep in mind?
Yes, definitely! Mongolian Beef is versatile; however, if you’re cooking for someone with allergies, take care to check the soy sauce and hoisin sauce for gluten. You can opt for gluten-free soy sauce and adjust the recipe accordingly. And if making it for pets, remember that onions are toxic to dogs and cats, so it’s best to leave them out of their portion.
How do I make Mongolian Beef spicier?
Very simply! To kick up the heat in your Mongolian Beef, add more dried red chilies or substitute them with fresh Thai chilies for an extra punch.
