Prepare the Beef
- Slice the flank steak very thinly (about 1/4-inch thick) against the grain. This is crucial for tenderness. For best results, freeze the steak for 20-30 minutes to firm it up before slicing.
- In a medium bowl, combine the sliced beef, 1/4 cup of cornstarch, and black pepper. Toss well until each piece of beef is lightly and evenly coated. Set aside.
Make the Sauce
- In a separate small bowl, whisk together the low-sodium soy sauce, water, dark brown sugar, minced ginger, and minced garlic. Continue whisking until the sugar is mostly dissolved. Set aside.
Fry the Beef
- Heat the 1/2 cup of vegetable oil in a large wok or heavy-bottomed skillet over medium-high heat. The oil is ready when it shimmers. To test, drop a small piece of coated beef in; it should sizzle immediately.
- Carefully add half of the coated beef to the hot oil in a single layer, ensuring not to overcrowd the pan. Fry for 1-2 minutes per side until golden brown and crispy.
- Using tongs or a slotted spoon, remove the cooked beef and place it on a wire rack or a plate lined with paper towels to drain excess oil. Repeat the process with the remaining beef.
Combine and Finish
- Carefully pour out all but 1 tablespoon of oil from the wok. Return the wok to medium heat.
- Pour the prepared sauce mixture into the wok and bring it to a simmer, stirring frequently. Let it bubble for 1-2 minutes to allow the flavors to meld.
- Add the crispy beef back into the wok with the sauce. Gently toss everything together for about 30-60 seconds, until the beef is fully coated in the glossy, thickened sauce.
- Remove from heat immediately to prevent the beef from getting soft. Serve hot over a bed of steamed rice, garnished with fresh green onions and toasted sesame seeds.
Notes
• Slicing Tip: For easier slicing, place the flank steak in the freezer for 20-30 minutes before cutting. This firms up the meat, allowing for paper-thin slices against the grain.
• Don't Overcrowd: Frying the beef in batches is key to getting it crispy. Overcrowding the pan will steam the meat instead of frying it.
• Spice it Up: For a spicy kick, add 1/2 teaspoon of red pepper flakes or a tablespoon of sriracha to the sauce.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. The beef will lose some of its crispiness upon reheating. Reheat gently in a skillet or microwave.
