Mongolian Beef (PF Changs copycat): Step-by-Step Guide

Step 1: Prepare the Beef
Start by slicing the flank steak into thin strips against the grain. This will ensure the beef is tender and easy to chew. If you find it challenging to cut, placing the steak in the freezer for 30 minutes can make it easier to slice.
Step 2: Marinate the Beef
In a mixing bowl, combine the soy sauce, water, minced ginger, and minced garlic. Add the sliced beef to the marinade and let it sit for at least 15 minutes to absorb the flavors.
Step 3: Coat the Beef
After marinating, drain the beef and discard the marinade. In another bowl, coat the beef strips with cornstarch evenly. This will create a crispy outer layer when fried.
Step 4: Heat the Oil
In a large skillet or wok, heat 1 cup of vegetable oil over medium-high heat. Once the oil is hot, carefully add the beef strips in batches, making sure not to overcrowd the pan.
Step 5: Fry the Beef
Fry the beef for about 2-3 minutes on each side until golden brown and crispy. Use a slotted spoon to remove the beef and place it on a paper towel-lined plate to drain excess oil.
Step 6: Make the Sauce
In the same skillet, remove excess oil, leaving about 1 tablespoon. Add the dark brown sugar and stir until it begins to dissolve. Then, add the remaining marinade (soy sauce mixture) and bring it to a simmer.
Step 7: Combine and Serve
Once the sauce is slightly thickened, return the fried beef to the skillet. Toss to coat the beef in the sauce. If you like a little heat, sprinkle in the red pepper flakes at this stage. Finally, add the green onions and stir-fry for an additional minute before serving.
Healthier Substitutions

- Low-sodium soy sauce: For a healthier alternative, consider using low-sodium soy sauce to reduce sodium intake.
- Honey or agave syrup: Substitute dark brown sugar with honey or agave syrup for a natural sweetener.
- Lean cuts of beef: Use sirloin or tenderloin for a leaner option instead of flank steak.
- Steamed vegetables: Add steamed broccoli or bell peppers for a nutrient boost and extra color.
Things That Go Wrong
- Overcooking the beef: Make sure to fry the beef just until crispy to avoid it becoming tough.
- Too much sauce: If the sauce is too thick, add a little water to reach your desired consistency.
- Uneven cooking: Fry the beef in batches to ensure even cooking and crispness.
- Gummy texture: If you skip the cornstarch coating, the beef may turn out gummy rather than crispy.
Freezer-Friendly Notes
Mongolian Beef can be a great make-ahead meal. To freeze, allow the cooked beef to cool completely, then transfer it to an airtight container. It can be stored in the freezer for up to 3 months. To reheat, simply thaw in the refrigerator overnight and warm it up in a skillet over low heat, adding a splash of water or broth to prevent drying out.
