Ingredients You’ll Need

• 450g flank steak or sirloin, thinly sliced against the grain
• 60g cornflour (cornstarch)
• 120ml vegetable oil, divided
• 1 large onion, thinly sliced
• 4 cloves garlic, minced
• 2cm fresh ginger, grated
• 120ml soy sauce (low sodium preferred)
• 120ml water or beef stock
• 100g light brown sugar
• 2 tablespoons rice vinegar
• 1 teaspoon sesame oil
• 1 teaspoon dried chilli flakes (optional, for a hint of warmth)
• Fresh spring onions, sliced, for garnish

Tip: Freezing your beef for about 30 minutes before slicing can make it much easier to achieve those perfectly thin, uniform pieces that are essential for this dish. This ensures even cooking and maximum tenderness.

How to Make P.F. Chang’s Mongolian Beef Copycat

1. Prepare the Beef: Begin by slicing your beef against the grain into thin, bite-sized strips, aiming for pieces about 0.5cm thick. Place the sliced beef in a medium bowl, sprinkle over 60g of cornflour, and toss thoroughly until every piece of beef is lightly coated and looks pale and powdery. Set aside to marinate for at least 30 minutes at room temperature – this coating will create a beautifully crisp exterior and help thicken the sauce later.
2. Make the Sauce Base: While the beef marinates, prepare the sauce. In a separate bowl, whisk together the soy sauce, 120ml water or beef stock, light brown sugar, rice vinegar, sesame oil, and optional chilli flakes. Stir until the sugar is fully dissolved and the mixture is a uniform brown liquid, smelling faintly sweet and savoury. Set this aside.
3. Sauté the Aromatics: Heat 2 tablespoons of vegetable oil in a large frying pan or wok over medium-high heat until it shimmers. Add the thinly sliced onion and cook for 3-4 minutes, stirring occasionally, until the slices soften and become translucent, releasing a sweet, pungent aroma. Add the minced garlic and grated ginger, cooking for another minute until fragrant, being careful not to let them brown too much, as they will smell slightly toasted.
4. Cook the Beef (in Batches): Remove the cooked aromatics from the pan and set them aside. Add the remaining vegetable oil to the pan and increase the heat to high. Once the oil is very hot and shimmering, add about a third of the cornflour-coated beef in a single layer. You should hear a distinct sizzling sound immediately. Cook for 2-3 minutes per side, turning once, until the beef is deeply browned and crispy on the edges, turning a rich, caramelised brown colour. Do not overcrowd the pan, or the beef will steam instead of fry. Repeat with the remaining beef in two more batches, ensuring each batch achieves that lovely golden-brown crust.
5. Combine and Thicken the Sauce: Once all the beef is cooked, return the aromatics and all the cooked beef to the pan. Pour the prepared sauce mixture over the beef and onions. Bring the sauce to a boil, stirring gently. As it heats, you’ll notice the sauce starting to thicken and become glossy, transforming into a beautiful rich, dark brown glaze that clings to the beef, usually within 2-3 minutes. It should coat the back of a spoon.
6. Finish and Serve: Once the sauce has thickened to your desired consistency, remove the pan from the heat. Give it a final stir to ensure everything is evenly coated. Garnish generously with freshly sliced spring onions, which will add a lovely vibrant green colour and a fresh, mild oniony bite. Serve immediately while hot.

Tips From My Kitchen

• Slice the Beef Thinly and Against the Grain: This is absolutely crucial for tenderness. Slicing against the grain shortens the muscle fibres, making the beef much easier to chew and more pleasant to eat. Aim for slices around 0.5cm thick. If the beef is too thick, it will be tough and won’t absorb the sauce as effectively, leading to a less authentic texture.
• Coat the Beef Evenly with Cornflour: The cornflour coating does double duty. Firstly, it creates a protective crust when fried, locking in the beef’s moisture and leading to incredibly tender results. Secondly, it acts as a thickener for the sauce, ensuring that glossy, sticky consistency we all love. Make sure every piece is covered, giving it a uniform, pale appearance before frying.
• Don’t Overcrowd the Pan When Frying Beef: This is a common pitfall. If you add too much beef to the pan at once, the temperature of the oil will drop drastically. Instead of searing and browning, the beef will steam and become grey and tough. Work in batches, leaving enough space for the heat to circulate and for the beef to achieve that beautiful caramelised crust. Patience here pays off immensely in flavour and texture.
• Use Fresh Ginger and Garlic: While convenience often tempts us towards pre-minced jars, fresh ginger and garlic make a world of difference to the vibrancy and depth of flavour in this dish. They release their essential oils more effectively when freshly prepared, contributing to a brighter, more aromatic sauce that truly elevates the overall taste profile.
• Taste and Adjust the Sauce Before Adding to Beef: Before you pour the sauce over the cooked beef, give it a little taste. This is your opportunity to adjust the balance of sweet, savoury, and tangy flavours. If it’s too sweet, a touch more soy sauce or vinegar can help. If it’s too salty, a splash of water or stock will mellow it out. Getting the sauce just right at this stage ensures the final dish is perfectly balanced to your preference.
• High Heat is Your Friend for Stir-Frying: Stir-frying is meant to be done quickly over high heat. This method caramelises the exterior of the ingredients while keeping the interior tender-crisp. A very hot pan creates that desirable smoky “wok hei” flavour and prevents the beef from stewing. Ensure your pan is smoking slightly before adding the oil and then the beef.

Equipment You’ll Need

• Large frying pan or skillet
• Sharp knife and cutting board
• Mixing bowls
• Wooden spoon or spatula

Common Mistakes to Avoid

• Overcrowding the pan: When you overcrowd the pan with beef, the temperature drops rapidly, and instead of searing and developing a crust, the beef will steam. This results in grey, tough meat rather than tender, browned pieces. Always cook the beef in small batches to maintain high heat and achieve that desirable caramelised exterior.
• Wrong temperature: Frying the beef at too low a temperature will lead to it stewing in its own juices, making it tough and pale. Conversely, if the heat is too high and the oil is smoking excessively, the cornflour coating can burn before the beef is properly cooked. Aim for medium-high to high heat, with the oil shimmering but not smoking excessively, around 180-190°C (350-375°F).
• Skipping the rest time: While not a lengthy rest, allowing the beef to marinate with the cornflour for at least 30 minutes is important. This allows the cornflour to properly adhere to the meat, creating a better crust when fried and ensuring the beef stays tender. Skipping this can lead to the coating falling off and less tender beef.

Delicious Variations to Try

• Spicy Version: For those who enjoy a bit of heat, you can easily ramp up the spice. Increase the amount of dried chilli flakes in the sauce to 2-3 teaspoons, or add a finely chopped red bird’s eye chilli along with the garlic and ginger for a fresher, more immediate kick. A dash of sriracha at the end can also provide a lovely fiery finish.
• Vegetarian/Vegan Option: This dish adapts beautifully for a plant-based diet. Substitute the beef with firm tofu or tempeh, pressed and cubed, or use large slices of portobello mushrooms. Ensure to coat them in cornflour and fry until golden and crispy before adding to the sauce. You can also use vegetable stock instead of beef stock in the sauce.
• Different Protein: While beef is traditional, other proteins work wonderfully too. Thinly sliced chicken breast or thigh can be used in place of beef, following the same cornflour coating and frying method. You could also try prawns (shrimp) for a seafood twist, cooking them for a shorter time until just pink and opaque.
