The flank steak is non-negotiable for this dish—its lean yet tender texture holds up perfectly when sliced thin against the grain. Ask your butcher to slice it if you can't do it yourself; most grocery stores will do it for free. For the marinade, Kikkoman soy sauce delivers the right balance of salt and umami without overwhelming the dish. The cornstarch isn't just for thickening—it helps tenderize the beef during the quick sear. Fresh ginger and garlic? Buy them whole and grate/mince yourself—pre-minced jars lack the punch. Store these in the freezer once opened to preserve flavor.
No sesame oil? Toasted peanut oil at half the amount works in a pinch, though it'll have a different profile. Substituting bell peppers? Snap peas or zucchini work beautifully—just adjust cooking time slightly. The broccoli and carrots should be cut uniformly for even cooking; julienne peeler attachments make quick work of this. For the sauce, if you can't find seasoned rice vinegar, substitute white vinegar plus 1/2 tsp sugar. The honey should be pure—no high-fructose corn syrup substitutes here. Prefer a different rice? Basmati or short-grain both work well, though jasmine's floral notes complement the dish perfectly.
Store prepped vegetables in airtight containers with paper towels to absorb moisture—lasts 3 days in the fridge. The cooked beef reheats beautifully but loses texture after 2 days, so plan to eat it fresh. For meal prep, cook rice separately and store components separately to maintain texture. Sesame seeds and green onions can be toasted and stored in a jar for up to 2 weeks. The sauce keeps for 5 days refrigerated or 3 months frozen—perfect for batch cooking.

Step-by-step instructions for america's test kitchen beef stir fry
This method delivers restaurant-quality wok-hei in your home kitchen with precise timing and technique.
Prep the Flank Steak for Maximum Tenderization
Slice the 1 lb flank steak thinly against the grain into ¼-inch strips—this ensures tender bites. Place the strips in a large bowl and sprinkle evenly with the 2 tbsp cornstarch. Toss gently to coat all surfaces completely, then let sit for 10 minutes at room temperature. This cornstarch slurry creates a protective barrier that prevents the beef from overcooking while adding texture.
While the steak marinates, prepare the remaining vegetables. Slice the 2 medium bell peppers into ¼-inch strips and cut the 2 medium carrots into 2-inch julienne strips. Separate the 2 cups broccoli florets into bite-sized clusters. Keep all vegetables in separate piles until ready to cook—this prevents premature wilting.
Cook the Jasmine Rice to Perfect Texture
Rinse the 1.5 cups jasmine rice thoroughly under cold water until the water runs clear. This removes excess starch that would make the rice gummy. Combine the rice with 3 cups water in a pot and bring to a boil over high heat. Once boiling, reduce to low heat, cover tightly, and simmer for 15 minutes. Turn off the heat and let it steam, covered, for another 10 minutes. The rice should be tender but still slightly firm—this prevents a mushy texture when combined with the stir fry.
While the rice cooks, prepare the sauce. In a small bowl, whisk together the 0.5 cup low-sodium soy sauce, 1 tbsp honey, 1 tbsp rice vinegar, 2 tbsp sesame oil, 6 cloves minced garlic, and 1 tbsp finely grated fresh ginger. Let the mixture sit for 5 minutes to allow the flavors to meld. This pre-marinated sauce ensures balanced sweetness, acidity, and umami in every bite.
Stir-Fry the Vegetables to Crisp-Tender Perfection
Heat a 14-inch wok or large skillet over high heat until a drop of water sizzles violently and evaporates instantly. Add 1 tbsp neutral oil and swirl to coat the pan. Add the bell peppers and carrots first, stirring constantly for 2-3 minutes until they begin to soften but remain vibrant in color. Add the broccoli florets and continue stirring for another 2 minutes—the vegetables should be bright green and crisp-tender, not mushy.
Remove the vegetables to a plate and set aside. Immediately add the remaining 1 tbsp neutral oil to the wok. The high heat is crucial here—it creates the signature "wok-hei" or "breath of the wok" flavor that distinguishes professional stir fries from home versions.
Cook the Flank Steak to Juicy Doneness
Working in batches if needed, add the cornstarch-coated steak strips to the wok in a single layer. Stir-fry vigorously for 1-2 minutes until the exterior develops a deep golden brown crust and the internal temperature reaches 140°F on an instant-read thermometer. The steak should be just cooked through—overcooking will make it tough. Remove the steak to a clean plate and tent loosely with foil to keep warm.
Return the cooked vegetables to the wok and pour in the prepared sauce. Stir everything together for 1-2 minutes until the sauce coats the vegetables evenly and begins to glaze slightly. The residual heat will finish cooking the vegetables while infusing them with the sauce's complex flavors.
Combine and Serve Immediately
Return the steak to the wok and toss everything together for 30 seconds to ensure even distribution of the sauce. Sprinkle with 1 tbsp toasted sesame seeds and 2 whole green onions, sliced thinly. Serve the stir fry immediately over the jasmine rice, garnishing each portion with additional green onions if desired.
The dish should be vibrant, with bright vegetables, juicy steak, and a glossy, balanced sauce that coats every bite. Each component should be hot when served—this ensures the perfect texture contrast between the crisp-tender vegetables and tender beef. Leftovers can be refrigerated for up to 2 days, though the texture will change slightly upon reheating.
Pro Tips For Making America'S Test Kitchen Beef Stir Fry
- SLICE THIN, STACK HIGH: I learned this the hard way—flank steak fights back when it’s uneven. Cut each slice paper-thin (⅛-inch max) against the grain, then stack them like a Jenga tower before slicing again. This keeps the meat tender and prevents that sad, chewy bite you get when you rush the prep.
- REST THE STEAK, DON’T SKIP: After cooking, give that flank steak a solid 5-10 minutes under foil before slicing—yes, even if you’re starving. The muscle fibers relax, and the meat stays juicy instead of turning into a tough, stringy mess. I know, I know, but trust the process.
- WHISK THE SOY SAUCE: Low-sodium soy sauce is your savior, but don’t just dump it in. Whisk it with a splash of water (or even a teaspoon of cornstarch slurry) to dissolve any lingering salt crystals—those can make your stir-fry taste flat or overly salty. A quick stir makes all the difference.
- START HOT, FINISH LOW: Crank the heat to high for the first 30 seconds of cooking the beef—you want a good sear. Then, drop it to medium-high and keep moving the meat. Rushing the sear leads to gray, rubbery beef, and letting it sit too long in the pan turns it into a sad, overcooked pile. Balance is everything.
Common mistakes when making this recipe
Overcrowding the Wok
One of the biggest mistakes is overloading your wok or pan with too many ingredients at once. This drops the temperature dramatically, causing vegetables to steam instead of sear. I've seen home cooks toss everything in at once, thinking it's faster—it's not. Instead, cook vegetables in batches: bell peppers first, then carrots, then broccoli. This keeps the heat high and maintains that signature wok-hei flavor. 🔥
Skipping the Cornstarch
Many people skip the cornstarch step, thinking it's optional. But that 2 tbsp cornstarch is crucial—it creates a protective barrier that keeps the beef tender during the quick sear. Without it, your steak strips will turn tough and chewy. I've tested this recipe both ways, and the difference is night and day. Don't skip it!
Not Prepping Ingredients Properly
Unevenly cut vegetables cook at different rates, leading to some pieces being mushy while others remain crunchy. Always slice bell peppers into ¼-inch strips, julienne carrots into 2-inch pieces, and cut broccoli into bite-sized florets. Use a sharp knife or mandoline for precision. I recommend prepping everything while the rice cooks to stay organized.
Low and Slow Cooking
Stir-fries need high heat to develop that smoky, caramelized flavor. Cooking at medium heat will result in soggy vegetables and bland beef. Your wok should be so hot that a drop of water sizzles violently before adding oil. If you're not getting that reaction, increase the heat and let it preheat longer. This is non-negotiable for authentic texture.
Ignoring the Sauce Timing
Adding sauce too early steams the vegetables instead of glazing them. The sauce should only be added after the beef is removed from the wok. Then, return the beef to the wok with the sauce for just 30 seconds of tossing. This ensures the sauce coats everything evenly without making the vegetables soggy. I've ruined many stir-fries by adding sauce prematurely—don't make my mistake!
Letting the Beef Rest Too Long
While it's tempting to let the beef rest for hours like a steak, stir-fry beef should be served immediately. The cornstarch coating works best when the beef is hot. If you must keep it warm, tent loosely with foil for no more than 10 minutes while finishing the vegetables. Any longer, and the texture suffers. Serve it fresh for the best results. ✨

Frequently asked questions about america's test kitchen beef stir fry
Can I use a different cut of beef instead of flank steak?
Flank steak is ideal for its lean yet tender texture, but you can substitute with sirloin tip or ribeye cut into thin strips. Avoid fatty cuts like ribeye—too much fat will make the stir-fry greasy. If using sirloin tip, trim excess fat first. The key is keeping the slices ¼-inch thick and slicing against the grain.
How do I get that perfect wok-hei flavor at home?
Wok-hei (breath of the wok) comes from high heat and proper technique. Use a 14-inch wok or heavy skillet and heat it until a drop of water sizzles violently. Work in batches—don't overcrowd—and keep stirring constantly. The cornstarch coating on the beef also helps create that signature smoky flavor when seared properly. A gas stove works best, but electric burners can achieve it with patience.
What if I don't have a wok?
A heavy-bottomed 12-inch cast iron skillet or carbon steel pan works perfectly. The key is getting the pan as hot as possible before adding oil. If your pan isn't wide enough, cook in batches—start with vegetables, then beef, then sauce. The high heat is more important than the shape of the pan. Just avoid nonstick—it can't handle the high temperatures needed for authentic texture.
Can I make this gluten-free?
Yes! Replace the soy sauce with tamari or coconut aminos (use the same ½ cup amount). For extra umami, add 1 tbsp gluten-free fish sauce to the sauce mixture. Check labels—some rice vinegars contain wheat. The cornstarch is naturally gluten-free, but if you need to avoid it entirely, substitute with arrowroot powder instead. The texture will be slightly different but still tender.
How can I prevent the sauce from making the vegetables soggy?
Timing is everything! Add the sauce only after removing the beef from the wok. Return the beef to the pan with the sauce for just 30 seconds of tossing—this ensures even coating without overcooking. Also, make sure your vegetables are crisp-tender before adding sauce. If they're too soft, they'll absorb the sauce and become mushy. Work quickly and keep everything hot!
