Ingredients for bang bang beef

Pantry staples plus a few specialty touches create this addictive crispy-spiced beef dish.

The flank steak is your star—look for well-marbled cuts at Whole Foods or your local butcher. Thinly slicing it against the grain transforms tough meat into tender bites. Costco often has pre-sliced flank steak if you're short on time. For the marinade, Kikkoman soy sauce delivers the best balance of salt and umami, but any good-quality soy works. Fresh ginger and garlic? Trader Joe's has pre-grated ginger in the freezer section—game changer when you're in a rush. Toast your sesame seeds in a dry pan until fragrant for that nutty crunch.

No cornstarch? Arrowroot powder at half the amount works just as well. Short on sesame oil? Avocado oil mimics the toasted aroma if you're in a pinch. The glaze can be made ahead—just store it in the fridge and reheat gently. For extra heat, add a dash of Sriracha to the glaze. If you're serving this for kids, skip the chili flakes and use smoked paprika instead. The brown sugar? Light or dark both work, but light keeps the glaze from getting too dark.

Marinate the beef for at least 30 minutes—overnight is best. The glaze keeps for 1 week in the fridge, so double it if you're prepping ahead. Store the cooked beef in an airtight container with a paper towel to absorb any moisture. Reheats beautifully—just warm in a skillet or air fryer. Freeze for up to 3 months if you're planning ahead. Pair with steamed jasmine rice to soak up all that sticky glaze.

Step-by-step instructions for crispy-spiced beef

Here's how to nail that perfect crunchy exterior with tender, flavorful beef every time.

Slice the 1.5 lb flank steak thinly against the grain into ¼-inch thick strips. The grain runs lengthwise, so look for those muscle fibers and cut perpendicular. Transfer to a bowl and add 0.5 cup soy sauce, 0.25 cup packed brown sugar, 6 minced garlic cloves, and 2 tbsp finely grated ginger. Mix well until the meat is fully coated in the marinade.

Let it marinate for at least 30 minutes at room temperature—this ensures even flavor penetration. If you have time, marinate overnight in the fridge for deeper flavor. The sugar will start caramelizing slightly, which is perfect for that sticky glaze we're after. Don't skip this step—it's what makes the final dish sing.

In a shallow bowl, mix together 2 tbsp cornstarch, 1 tbsp toasted sesame oil, 1 tsp ground black pepper, and 1 tsp red chili flakes. This is your crispy armor—don't skimp on the cornstarch. The sesame oil adds that nutty aroma while the chili flakes bring the heat.

Remove the beef from the marinade (reserve the marinade for later) and pat it dry with paper towels. This step is crucial—wet beef won't crisp properly. Toss the beef strips in the cornstarch mixture until they're fully coated. You'll see that perfect white crust forming, which is what gives bang bang beef its signature crunch. Let them sit for 5 minutes to help the coating adhere.

Heat 0.5 cup vegetable oil in a large skillet over medium-high heat until it shimmers but doesn't smoke. Add the cornstarch-coated beef in a single layer—don't overcrowd the pan or it'll steam instead of crisp. Cook for 2-3 minutes per side until the beef is golden brown and the cornstarch coating is crispy and crackling.

You'll know it's ready when you can hear that satisfying crunch and see the edges starting to darken. If you see the coating breaking apart, that's perfect—it means it's getting that extra crispy texture. Transfer the cooked beef to a paper towel-lined plate to drain excess oil. Keep the oil in the pan for the next step.

Return the pan to medium heat and add the reserved marinade, scraping up any browned bits from the bottom. Bring to a simmer and cook for 3-4 minutes until it reduces by half and starts to thicken. Then stir in 1 tbsp corn syrup and 1 tbsp rice vinegar. The syrup helps the glaze stick to the beef while the vinegar adds brightness.

Simmer for another 1-2 minutes until the sauce coats the back of a spoon. It should be sticky but not too thick—you want it to cling to the beef without being syrupy. If it's too thick, add 1-2 tablespoons of water to loosen it. Taste and adjust seasoning with a pinch more soy sauce or sugar if needed.

Add the crispy beef back to the pan with the glaze and toss everything together until the beef is fully coated. Cook for another 1 minute to let the flavors meld. Then transfer to a serving platter and sprinkle with 2 tbsp toasted sesame seeds and 4 thinly sliced green onions.

Here's the thing about serving bang bang beef—it's all about that contrast. The crispy exterior should give way to tender beef with each bite, and that sticky glaze ties it all together. Serve immediately while everything is still crispy and hot. The sesame seeds add texture while the green onions bring freshness to cut through the richness. Enjoy with steamed rice to soak up all that delicious sauce!

Flavor customization for this bang bang beef

Sweet & Tangy Glaze

Start with the classic bang bang beef glaze but customize it to your taste. For extra sweetness, add 1 extra tablespoon of brown sugar or 1 teaspoon of honey to the sauce. If you prefer tanginess, increase the rice vinegar to 2 tablespoons or add ½ teaspoon of lemon juice. The glaze should coat the back of a spoon—adjust consistency with water if needed. 🍯

Spice Level Control

Adjust the heat to your preference by tweaking the red chili flakes. For mild heat, reduce to ½ teaspoon or swap for ½ teaspoon smoked paprika. For extra kick, add ½ teaspoon of gochujang (Korean chili paste) or 1 teaspoon of sriracha to the glaze. Always taste as you go—this is your dish!

Protein Swaps

While flank steak is traditional, you can use sirloin strips or chuck roast for a heartier bite. For a lighter option, try chicken thighs or pork tenderloin. Just marinate for 15-20 minutes less if using chicken, as it cooks faster. The cornstarch coating works on all proteins—just adjust cooking time to avoid overcooking. 🥩

Texture Variations

Want extra crunch? Add 1 tablespoon crushed peanuts or toasted sesame seeds to the cornstarch coating. For a softer texture, reduce cornstarch to 1 tablespoon and replace with 1 tablespoon all-purpose flour. The key is balance—too much coating steals from the beef's tenderness. Test with a small batch first!

Flavor Fusion Ideas

Give your bang bang beef a global twist! Add 1 teaspoon of fish sauce for a Thai-inspired depth, or ½ teaspoon of five-spice powder for a Chinese fusion. For a Korean twist, stir in 1 teaspoon of gochugaru (Korean chili flakes) and ½ teaspoon of sesame oil after cooking. These tweaks keep the dish familiar while adding exciting new layers. 🌍

Make-Ahead Adjustments

Prep the glaze ahead and store it in the fridge for up to 1 week. For the beef, marinate overnight but skip the cornstarch coating until ready to cook—it loses crispiness when stored. Reheat in a skillet with 1 teaspoon of oil over medium heat for 2-3 minutes per side. The glaze will reheat best when warmed gently with a splash of water. 📅
