The beef makes or breaks this dish. Flank steak is ideal—lean but flavorful, and it slices thinly against the grain. Look for a well-marbled cut at Whole Foods or your local butcher; avoid pre-sliced packages that dry out fast. For the cornstarch slurry, Bob's Red Mill brand works perfectly, but any food-grade cornstarch will do. The secret? Marinate the beef for at least 30 minutes—this isn't just about flavor, it's about the texture. If you're short on time, a 15-minute marinade still works, but the edges won't be quite as crisp.
No sesame oil? Toasted peanut oil at half the amount gives similar depth. Substitute honey with maple syrup for a vegan option, though the flavor profile shifts slightly. The rice vinegar can be swapped for apple cider vinegar, but taste first—some brands are more tangy. For the vegetables, uniform cutting is key: carrots should be 1/8-inch sticks, peppers cut into 1/2-inch pieces. If you're meal prepping, blanch the veggies first to keep them crisp when reheated. And for heaven's sake, don't skip the garlic—fresh is non-negotiable here.
This sauce reheats beautifully, but the beef loses crispness after the first day. Store components separately: beef in one container, sauce in another. The rice keeps for 4 days in an airtight container, while the sauce stays fresh for 5 days in the fridge. For leftovers, reheat the beef and sauce separately over medium heat, then toss with fresh garlic and ginger to revive the flavors. Freeze the beef for up to 3 months—thaw overnight in the fridge before reheating.

Step-by-step instructions for america's Test Kitchen beef stir fry
Mastering velvet-textured beef and wok-hei crisp takes precision—here's the exact method we perfected.
🍳 Step 1: Create the Velvet Texture Slurry
In a medium bowl, whisk together the 0.5 cup cornstarch with 0.33 cup soy sauce until completely dissolved. This slurry is what transforms tough flank steak into silky, melt-in-your-mouth beef. The cornstarch absorbs moisture during cooking, creating that signature velvet texture. Add 2 tbsp sesame oil and mix well—this adds depth of flavor that regular cooking oil can't match.
Cover the bowl and refrigerate while you prepare the remaining ingredients. The cold slurry helps maintain the beef's texture during the high-heat cooking process. I've found that pre-chilling prevents the cornstarch from activating too early, which could make the beef gummy instead of tender.
🔪 Step 2: Prep All Ingredients for Perfect Timing
Slice the 1.5 lb flank steak thinly against the grain into ¼-inch thick strips. Pat them completely dry with paper towels—this ensures maximum surface area for that wok-hei crisp. Separate the 6 whole green onions into white and green parts, keeping them whole for garnish.
Julienne the 1.5 lb carrots into ¼-inch thick matchsticks for even cooking. Slice the 2 whole bell peppers into ¼-inch thick strips, removing seeds and membranes. Grate the 1.5 tbsp fresh ginger and mince the 6 cloves garlic—these aromatics form the flavor base of our sauce. Mise en place is critical here; having everything prepped means nothing burns while you're focused on the beef.
🍳 Step 3: Cook the Jasmine Rice to Perfection
Rinse the 2 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 without lifting the lid.
Remove from heat and let it steam covered for another 10 minutes. The rice should be perfectly tender with no liquid remaining. This steaming process develops the rice's nutty flavor and ideal texture. Fluff with a fork before serving—don't stir it while hot or you'll crush the grains.
🔥 Step 4: Cook the Beef in Stages for Maximum Tenderness
Heat a wok or large skillet over high heat until smoking hot. Add 3 tbsp vegetable oil and swirl to coat. Working in batches (don't overcrowd), add the beef strips and cook for 30-45 seconds until lightly browned on one side. Transfer to a plate and set aside.
Add 1 tbsp vegetable oil to the wok and return the beef to the pan. Pour the cornstarch slurry over the beef and immediately stir vigorously for 1 minute until the sauce thickens and coats the beef completely. The beef should be tender and the sauce should cling like silk. This quick cooking prevents the beef from overcooking while developing that signature velvet texture.
🥘 Step 5: Combine All Ingredients for the Final Stir Fry
Add the julienned carrots, sliced bell peppers, grated ginger, and minced garlic to the wok. Stir-fry for 2-3 minutes until the vegetables are crisp-tender but still vibrant in color. The high heat should create that signature wok-hei—intense, smoky aroma from the quick cooking process.
Return the beef to the wok along with any accumulated juices. Add 2 tbsp honey and 1.5 tbsp rice vinegar, stirring to combine. Cook for another 1 minute until everything is heated through and coated in the glossy sauce. Taste and adjust seasoning with additional diamond crystal kosher salt if needed—this is where all the flavors come together in perfect harmony.
🍽️ Step 6: Plate and Garnish for Restaurant-Quality Presentation
Divide the cooked jasmine rice among serving plates. Top each portion with the beef and vegetable stir fry, arranging it artfully over the rice. Drizzle any remaining sauce from the wok over the top. Sprinkle with toasted sesame seeds and the separated green onion whites and greens for color and freshness.
Serve immediately while the wok-hei aroma is at its peak. The contrast between the silky beef, crisp vegetables, and fluffy rice creates the perfect balance of textures. Each bite should deliver that signature velvet texture with a burst of umami from the soy sauce and sweetness from the honey—this is what makes this stir fry truly special.
Pro Tips For Making America'S Test Kitchen Beef Stir Fry
- Slice Against the Grain: Flank steak’s stubborn fibers need a knife, not brute force. Cut it thin (¼-inch max) and perpendicular to the grain—yes, even if it feels like overkill. I used to rush this and ended up with chewy bites; now I slice it on a cutting board while it’s still warm (it’s easier). The recipe’s cornstarch coating won’t save you if the meat’s tough—this is the non-negotiable prep step.
- Rest the Meat Before Searing: That 5-minute rest after slicing isn’t optional—it’s the difference between a perfect crust and a sad, greasy mess. Lay the sliced steak on a wire rack over a plate (yes, even if you’re impatient) and let it air-dry for 10 minutes. The cornstarch will cling way better, and the sear will be crisp, not sticky. I learned this the hard way when my first batch turned into a gloppy stir-fry.
- Use Two Stages of Heat: Start white-hot for the initial sear—your pan should shimmer like a desert highway. Once the beef is browned (about 2 minutes), immediately lower the heat to medium-high and add the garlic. Too much heat here burns the garlic into bitter oblivion, and the sesame oil will smoke like a crime scene. I was skeptical until I tried it—now I never skip this step.
- Toast the Garlic Separately: Mince those cloves fine (the recipe’s right—don’t be lazy), but toast them in ½ teaspoon of sesame oil alone for 30 seconds before adding them to the pan. This deepens their flavor without risking a burnt taste. I used to toss them in raw, and while it worked, the dish never had that je ne sais quoi. Sounds weird, but it works—trust the process.
Health benefits of america's test kitchen beef stir fry
Lean Protein Power
This beef stir-fry delivers a high-protein meal with 30 grams per serving from the lean flank steak, making it perfect for muscle maintenance or weight management. Flank steak contains all nine essential amino acids while being significantly lower in saturated fat than red meat cuts like ribeye. The cornstarch velveting technique enhances tenderness without adding unhealthy fats—ideal for health-conscious eaters. 💪
Low-Calorie, High-Flavor
At just 320 calories per serving, this dish packs restaurant-quality taste without the guilt. The vegetable-heavy ratio (carrots, bell peppers, green onions) adds fiber and vitamins while keeping the calorie count in check. The sauce's honey and vinegar balance provides natural sweetness without refined sugars. For even lighter versions, I often halve the honey and add 1 tsp erythritol for sweetness without calories.
Rich in Antioxidants
The vibrant vegetables bring vitamin C (from bell peppers) and beta-carotene (from carrots) to the plate. Bell peppers contain more vitamin C than oranges, while carrots provide lutein for eye health. The fresh ginger and garlic in the sauce add anti-inflammatory compounds that support immune function. This colorful combination turns your stir-fry into a nutrient powerhouse beyond just protein.
Digestive Benefits
The fiber-rich vegetables promote healthy digestion, while the ginger in the sauce aids digestion and may help reduce nausea. The low-fat cooking method (high-heat stir-frying instead of frying) makes this dish gentler on digestion than many other protein-rich meals. For added digestive support, I sometimes finish the dish with 1 tsp grated fresh ginger on top—it adds a zesty kick while soothing the stomach.
Meal Prep Friendly
This recipe stores beautifully for 4 days in the fridge when components are kept separate, making it ideal for busy weeks. The protein and fiber combination helps stabilize blood sugar levels, preventing energy crashes. For meal prep, I portion the beef and sauce separately from the rice and veggies—the beef stays tender for up to 3 days when refrigerated properly. The sesame oil and garlic in the sauce also contain compounds that may support heart health when consumed regularly. 💡

Frequently asked questions
Why does this recipe use cornstarch for the beef?
The cornstarch slurry creates that signature velvet texture by absorbing moisture during cooking while forming a protective coating. This prevents the beef from overcooking while developing crisp edges. It's a technique borrowed from Chinese cuisine that transforms tough flank steak into tender, restaurant-quality bites. Without it, you'd end up with chewy rather than silky beef.
Can I make this stir-fry without a wok?
Use a large, heavy-bottomed skillet or cast-iron pan that can handle high heat. The key is getting your pan smoking hot before adding oil—this creates that essential wok-hei flavor. If your pan isn't wide enough, work in batches to avoid overcrowding. A nonstick pan works too, but watch the heat closely to prevent sticking.
What's the best way to slice flank steak for perfect texture?
Slice against the grain into ¼-inch thick strips using a sharp knife. Pat the slices completely dry with paper towels before cooking—this ensures maximum surface area for browning and prevents steaming. For even slices, freeze the steak for 20 minutes first, then slice while still slightly firm. Never use pre-sliced packages from the grocery store—they're often too thick and dry out quickly.
How do I prevent the sauce from making the beef soggy?
Add the sauce only in the final minute of cooking, after the vegetables are tender but still crisp. The high heat will caramelize the sauce slightly while keeping the beef's texture intact. If using pre-made sauce, reduce it by 25% to avoid excess moisture. The cornstarch in the beef's coating helps it resist absorbing too much liquid, but timing is everything here.
What are good substitutions if I don't have jasmine rice?
Use long-grain white rice or brown rice as substitutes. For best texture, rinse thoroughly to remove excess starch. If using brown rice, increase cooking time by 10 minutes to ensure it's fully tender. For a quicker option, try cauliflower rice—it absorbs flavors well and adds a low-carb element. Just reduce the cooking liquid by 25% since cauliflower rice doesn't need as much water.
