Soups & Stews
This Asian beef flank recipe delivers restaurant-quality wok-seared beef with a garlic-ginger glaze that balances sweet, savory, and umami in every bite. The secret lies in marinating the flank overnight to tenderize while infusing deep flavor—no dry, chewy results here. I developed this technique after years of perfecting stir-fry textures, and it transforms tough flank into melt-in-your-mouth slices with a crispy crust.
What sets this recipe apart is the two-stage cooking method: first marinating in a bold soy-ginger sauce, then searing the flank in a screaming-hot wok for that signature caramelized crust. The glaze reduces into a sticky, aromatic sauce that clings to each slice, creating a dish that's both elegant and approachable. This isn't just another stir-fry—it's a complete meal with restaurant-level depth.
By the time you're done, you'll have perfectly sliced beef with a crispy exterior and tender interior, all coated in that glossy, flavor-packed glaze. The aroma alone will have everyone gathering around the table, and each bite delivers a perfect balance of textures and flavors. It's the kind of dish that elevates weeknight dinners into special occasions without requiring hours in the kitchen.
Serve with steamed jasmine rice and quick-pickled vegetables for a traditional Asian spread, or pair with crusty bread to soak up that delicious glaze. The possibilities are endless, but the technique remains foolproof—ideal for both weeknight meals and impressing guests. Let's get cooking!

The beef flank steak is non-negotiable for this recipe—center-cut and 1-inch thick ensures even cooking and that coveted crispy crust. Look for USDA Choice or Prime at your local butcher shop or high-end grocery store like Whole Foods or H-Mart for authentic Asian cuts. If you can't find flank, flap meat or skirt steak work as substitutes, but slice against the grain for tenderness. The ginger and garlic should be freshly grated and minced, respectively—pre-minced garlic loses its punch quickly, and organic ginger from the produce section has more vibrant flavor. For the soy sauce, Lee Kum Kee or Kikkoman are reliable brands that deliver consistent depth.
No toasted sesame oil? Lightly toast regular sesame oil in a dry pan for 30 seconds to bring out its nutty aroma. Substituting honey? Maple syrup or agave nectar work in a pinch, though honey's floral notes are ideal. The cornstarch is crucial for that signature crispy exterior—arrowroot powder can replace it at a 1:1 ratio if needed. For the rice vinegar, seasoned rice vinegar adds subtle sweetness, but plain white vinegar works too. If you're short on time, pre-grated ginger (from the freezer section) saves steps, though fresh is always better. The green onions can be swapped for scallions or chives if that's what you have on hand, but the white parts add subtle sweetness that complements the dish beautifully.
Marinate the beef for at least 4 hours, but overnight is ideal for maximum tenderness. Store the marinade in an airtight container in the fridge, and the beef can stay submerged for up to 24 hours. The cooked beef holds well in the fridge for 3 days if stored in an airtight container, though it's best served fresh. For make-ahead convenience, freeze the marinated beef (uncooked) for up to 2 months—thaw in the fridge overnight before cooking. The jasmine rice can be cooked in advance and reheated with a splash of water, keeping it fluffy and separate. Garnishes like sesame seeds and green onions stay fresh for 5 days in the fridge if stored in a sealed container.

Step-by-step instructions for wok-seared beef flank with garlic-ginger glaze
Here's the method for achieving that perfect balance of caramelized crust and tender interior with a glossy, umami-packed glaze.
Prepare the Beef and Marinate for Maximum Flavor
Slice the 1.5 lb beef flank steak against the grain into ¼-inch thick strips. This cut ensures maximum tenderness when served. In a large bowl, combine the 0.5 cup soy sauce, 0.25 cup finely grated fresh ginger, 8 minced garlic cloves, 2 tbsp honey, and 2 tbsp rice vinegar. Add the beef strips and toss gently to coat completely. Cover and refrigerate for at least 4 hours—overnight is ideal. The acidity in the vinegar and soy sauce begins breaking down the muscle fibers, while the ginger and garlic infuse deep flavor.
Real talk: Don't skip this step. The marinade doesn't just flavor the meat—it transforms tough flank steak into something silky. I've found that beef needs this time to truly absorb the marinade's magic. When ready to cook, drain the beef but reserve the marinade for later use.
Create the Crispy Cornstarch Coating for Texture
In a medium bowl, combine 2 tbsp cornstarch, 1 tsp diamond crystal kosher salt, and 0.5 tsp freshly ground black pepper. Add the marinated beef strips and toss until each piece is evenly coated. This cornstarch crust is what creates that satisfying crunch when seared—don't skip this step or you'll miss the star of the dish. Let the coated beef sit at room temperature for 15 minutes while you prepare your cooking station.
I press the beef strips gently into the cornstarch mixture to ensure full coverage. The cornstarch will absorb any excess moisture from the marinade, creating the perfect foundation for that golden-brown crust. This is where the texture magic happens—don't be tempted to rush this preparation.
Wok-Sear the Beef for Perfect Crust and Doneness
Heat a wok or large skillet over high heat until smoking, then add 1 tbsp vegetable oil. Working in batches to avoid crowding, add the coated beef strips and sear for 1-2 minutes per side until the cornstarch coating turns deep golden brown and crispy. The high heat is crucial here—it creates that wok-hei (breath of the wok) flavor while developing the crust. Transfer the seared beef to a plate and tent with foil to keep warm.
Here's where it gets technical: You want the internal temperature to reach 130-135°F for medium-rare doneness. Use an instant-read thermometer to check the thickest piece—it should register just below 140°F when removed from heat. The beef will carry over to perfect doneness as it rests. If you don't have a thermometer, cut into a small piece to check—it should be pink in the center with a hint of red.
Build the Glazing Sauce and Finish the Dish
In the same wok, reduce heat to medium and add 0.25 cup neutral oil. Swirl to coat the pan, then add the reserved marinade (about ½ cup) and simmer for 3-4 minutes until slightly reduced. Stir in 1 tbsp toasted sesame oil and 1 tbsp toasted sesame seeds, then return the seared beef to the wok. Toss everything together for 1-2 minutes until the beef is evenly coated in the glossy glaze.
The sauce should be thick enough to coat the back of a spoon but still flow freely. If it's too thick, add 1-2 tablespoons of hot water to loosen it. The sesame oil adds depth of flavor while the toasted seeds contribute both texture and aroma. This is the moment that transforms simple seared beef into a restaurant-quality dish.
Serve with Jasmine Rice and Garnish
Cook the 1.5 cups jasmine rice according to package instructions—it should be perfectly steamed and fluffy. To serve, arrange the glazed beef strips over the rice and garnish with 0.25 cup sliced green onions. The contrast of the tender beef with the crisp rice creates the perfect bite. I like to serve this immediately while the beef is still sizzling slightly from the residual heat.
Each forkful should deliver that perfect combination of textures—the crispy cornstarch crust, the tender beef, the glossy glaze, and the aromatic rice. The dish holds well for 20-30 minutes if needed, but it's best served fresh when the beef is at its peak tenderness. For extra presentation, drizzle with any remaining glaze from the wok before serving.
Pro Tips For Making Asian Beef Flank
- Slice Against the Grain: The flank’s fibers run diagonally—cutting perpendicular to them makes every bite tender. Grab a sharp knife, angle it low, and slice thinly after resting (yes, even if you’re impatient like me). Thick slices? You’ll chew through it like a boot.
- Blister the Garlic: Toss those whole garlic cloves into the pan before the beef, and let them sizzle until deep golden—almost charred. That bitterness cuts through the soy’s saltiness and adds depth. I used to skip this, and the dish always tasted flat.
- Don’t Crowd the Pan: Flank steak needs room to sear, not steam. Cook it in batches if needed—overlapping slices turns them soggy and dulls the crust. A hot pan and a little patience (about 2-3 minutes per side) guarantee a proper sear.
- Marinate Overnight, But Not Too Long: Toss the flank in soy, ginger, and garlic at least 4 hours, but no more than 12—longer and the meat gets mushy. Use a zip-top bag for even coating, and slap it on the fridge shelf (not the door, where temps fluctuate). I learned this the hard way after a 24-hour "marinate" turned my steak to shoe leather.
Storing and reheating this dish
Refrigerator Storage
Store your cooked beef in an airtight container with a splash of the leftover glaze to maintain moisture. The beef stays fresh for 3 days at 40°F or below, though I recommend eating it within 2 days for peak tenderness. The cornstarch crust softens slightly over time, but reheating restores that satisfying crunch. 🥩
Freezer Prep
For longer storage, freeze the cooked beef in a single layer on a tray to prevent clumping, then transfer to a freezer bag with the glaze. It keeps for 2 months—thaw overnight in the fridge before reheating. I like to portion it into meal-sized servings for quick weeknight dinners. Avoid refreezing after thawing.
Stovetop Reheat
My preferred method: Heat 1 tbsp neutral oil in a wok over medium heat, then add the beef and glaze. Cook for 3-4 minutes, stirring occasionally, until the beef reaches 165°F internally. The cornstarch coating crisps up beautifully, and the glaze thickens slightly. Add a splash of water if needed to loosen it. ✨
Microwave Option
For speed, place beef and glaze on a microwave-safe plate, cover loosely with a damp paper towel, and heat on 50% power for 1-2 minutes. Stir halfway through to distribute heat evenly. The texture won't be as crispy as stovetop, but it's still delicious—just add a sprinkle of toasted sesame seeds for crunch.
Rice Handling
Reheat jasmine rice separately in a steamer basket or microwave with 1 tbsp water to prevent drying. The rice stays fluffy and absorbs any extra glaze beautifully. I like to serve the beef over fresh rice to maintain that restaurant-quality presentation. The contrast of warm rice and reheated beef makes every bite feel special.
Garnish Refresh
Revive the dish with fresh green onions and toasted sesame seeds before serving. These add brightness and texture that reheating can't fully replace. A drizzle of the reserved glaze from the freezer (if stored separately) adds that final umami punch. Trust me, this simple step makes all the difference! 💫

Frequently asked questions
Why is slicing against the grain so important for beef flank?
Slicing against the grain (perpendicular to the muscle fibers) shortens them, making each bite more tender. Flank steak has long muscle fibers that can feel tough when cut with the grain. For this recipe, aim for ¼-inch thick slices—thinner than traditional flank strips—to ensure melt-in-your-mouth texture while maintaining structure.
Can I substitute flank steak with another cut?
Yes! Skirt steak or flap meat work well as substitutes, but slice them against the grain too. Avoid tender cuts like ribeye—they'll overcook in the wok. For extra tenderness, marinate for 6-8 hours instead of overnight if using a leaner cut like flank.
What's the best way to test doneness without a thermometer?
Cut into the thickest piece—it should be bright red in the center for medium-rare (the ideal doneness). If it's grayish, it's overcooked. For medium, look for pink throughout. Remember: The beef will carry over 5-10°F while resting, so pull it when it's slightly under your target temperature.
How do I prevent the beef from sticking to the wok?
Use a well-heated wok (until smoking) and enough oil (1 tbsp per batch) to create a non-stick surface. Don't overcrowd the pan—work in small batches (about ½ lb at a time) to maintain high heat. A light dusting of cornstarch on the wok before adding oil also helps prevent sticking.
Can I make this recipe in a regular skillet?
While a wok gives the best wok-hei flavor, a 12-inch cast-iron skillet works perfectly. Use medium-high heat and keep the pan moving to mimic stir-fry technique. For extra crispiness, add ½ tbsp extra cornstarch to the coating. The glaze will still develop beautifully!
