The flank steak is non-negotiable for this recipe—its lean yet flavorful profile delivers that signature wok-seared texture. Look for center-cut flank steak with good marbling at Whole Foods or your local butcher; pre-sliced options from Costco save time but lack the same tenderness. Slice against the grain for melt-in-your-mouth bites, and marinate for at least 30 minutes (overnight is ideal) using soy sauce, honey, and sesame oil. The broccoli should be bright green and firm—avoid any with yellowing florets, as they’ll turn mushy during cooking. Fresh ginger and garlic are best sourced from the produce section, not the jarred aisle, for maximum aromatic impact.
No low-sodium soy sauce? Regular soy sauce plus half the salt called for works, but the flavor balance will differ slightly. Substituting honey with maple syrup (use one-third more) keeps the dish vegetarian-friendly. For sesame oil, toasted sesame oil is essential—flavored varieties can overpower the delicate sauce. If you’re short on time, prep the sauce components separately and assemble them just before cooking. The cornstarch is critical for that glossy, velvety finish; don’t skip it. Green onions add freshness, but scallions or chives work in a pinch if you’re out. Toast the sesame seeds in a dry pan for 30 seconds—they’ll add a nutty crunch that elevates the dish.
Marinated steak and prepped broccoli keep up to 2 days in the fridge, sealed in airtight containers. The sauce components (soy, honey, garlic, ginger) can be mixed ahead and stored for up to 1 week. For longer storage, freeze the sauce in ice cube trays—thaw and reheat gently. This dish reheats beautifully; stir-fry again over high heat for 2-3 minutes to restore crispness. Leftovers hold for 3-4 days in the fridge, though the flavors deepen overnight. Serve over steamed jasmine rice to soak up every last drop of that silky glaze—it’s worth the extra minute to cook the rice separately.

Step-by-step instructions for beef and broccoli flank steak
Master this wok-seared technique for perfect texture contrast—crisp edges on the beef, vibrant broccoli, and a glossy sauce.
Prepare the Flank Steak for Optimal Texture
Slice the 1.5 lb flank steak thinly against the grain into ¼-inch strips. This critical step ensures tender bites—thicker slices would remain chewy. Pat the slices dry with paper towels and season immediately with the 1 tsp Diamond Crystal kosher salt and 0.5 tsp freshly ground black pepper. Let them sit at room temperature for 10 minutes while you prep the rest.
Here's the thing—flank steak has a powerful beefy flavor but can be tough if not sliced properly. The grain runs lengthwise, so cutting perpendicular creates shorter muscle fibers that break down faster during cooking. Arrange the slices in a single layer on a plate and cover loosely with plastic wrap to prevent drying.
Create the Sauce Base with Perfect Balance
In a small bowl, whisk together the 0.5 cup low-sodium soy sauce, 2 tbsp honey, and 1 tbsp sesame oil. The honey adds natural sweetness that complements the savory soy without overpowering. In a separate bowl, mix the 1 tbsp cornstarch with 2 tablespoons water to create a slurry—this will thicken the sauce beautifully.
Taste the sauce mixture before adding to the wok. It should be tangy with a touch of sweetness. If you prefer more depth, add a pinch of the Diamond Crystal kosher salt. The cornstarch slurry is your secret weapon—it creates that signature glossy finish without making the sauce gluey.
Wok-Sear the Beef for Maximum Crispness
Heat a wok or large skillet over high heat until a drop of water sizzles violently upon contact. Add the 2 tbsp neutral oil and swirl to coat the surface. Working in batches if needed, add the flank steak strips and stir-fry for 1-2 minutes until they develop a deep caramelized crust. Remove the beef and set aside on a plate.
Don't overcrowd the pan—this is where most home cooks fail. If you add too much beef at once, the temperature drops and you lose that crucial sear. The beef should be golden brown with crisp edges when done. If you notice the oil smoking excessively, reduce the heat slightly but maintain high temperature for the sear.
Stir-Fry the Broccoli to Vibrant Perfection
Add the 2 cups fresh broccoli crowns to the same wok and stir-fry for 2-3 minutes over high heat. The florets should retain their bright green color while developing a slight blister on the edges. Add the 6 cloves minced garlic and 1 tbsp grated fresh ginger, cooking for another 30 seconds until fragrant.
Broccoli cooks quickly but needs that final sear to develop texture. If you see the florets wilting completely, you've overcooked them. They should be crisp-tender with a slight resistance when pierced with a fork. The garlic and ginger should be just visible in the pan, not browned—this ensures their bright, aromatic flavors shine through.
Combine and Finish with Silky Sauce
Return the beef to the wok and pour in the soy sauce mixture. Stir vigorously for 1 minute to coat everything evenly. Add the cornstarch slurry and cook for another 30-60 seconds until the sauce thickens to a glossy consistency that lightly coats the back of a spoon. The sauce should cling to the beef and broccoli without being overly thick.
Taste and adjust seasoning if needed—you might want to add a splash of water or more soy sauce for balance. Garnish with the 4 sliced green onions and 1 tsp toasted sesame seeds. Serve immediately over the prepared 1.5 cups jasmine rice to catch all that delicious sauce.
Pro Tips For Making Beef And Broccoli Recipe Flank Steak
- Slice Against the Grain: Flank steak’s tough fibers run diagonally—cutting perpendicular to them shortens the strands and makes every bite tender. Grab a sharp knife and angle those slices like you’re cutting through a deck of cards. (Yes, it takes practice, but your jaw will thank you.)
- Blanch Broccoli First: Toss broccoli crowns in boiling water for 30 seconds, then shock in ice water. This stops cooking, keeps them bright green, and ensures they’re tender-crisp when they hit the pan later. I learned this the hard way—overcooked broccoli in stir-fries is a crime.
- Don’t Crowd the Pan: Cook the steak in a single layer over high heat until deeply browned, then set it aside. Piling everything in at once steams the meat instead of searing it, and you’ll end up with soggy edges. A hot pan and space are your friends here—trust the process.
- Deglaze with Soy + Honey: After searing the steak, splash in 2 tablespoons low-sodium soy sauce and 1 teaspoon honey before adding broccoli. Let it reduce by half—this builds flavor faster than throwing everything in at once. (And yes, the honey caramelizes, so don’t skip the reduction.)
Essential equipment for this recipe
Wok Essentials
A carbon steel wok is my go-to for authentic wok-seared beef and broccoli—its thin base heats up quickly and evenly, creating that signature crisp-tender texture. I recommend the De Buyer 14-inch for its durability and heat retention.
If you're on a budget, a 12-inch stainless steel wok from Made In works well for smaller portions. Both require seasoning before first use—coat with oil and heat until smoking to create a natural non-stick surface. 🔥
Skillet Alternatives
No wok? No problem. A 12-inch cast iron skillet like the Lodge Pre-Seasoned delivers similar results with proper technique. The key is maintaining high heat—preheat your skillet for at least 5 minutes before adding oil.
For non-stick convenience, a 10-inch ceramic-coated skillet from GreenPan works, though it won't achieve the same caramelized crust. Just avoid overcrowding the pan to prevent steaming instead of searing.
Heat Control Tools
Precision is everything when cooking flank steak. A thermometer like the Thermoworks Smoke helps monitor your wok's temperature—aim for 500-550°F for that perfect sear. For smaller kitchens, an infrared thermometer from Kizen lets you check surface temps without touching the pan.
I also keep a heat-resistant spatula (like OXO Good Grips) nearby to stir without losing heat transfer. 🌡️
Cutting Gear
Thin, even slices are critical for tender beef. A sharp 8-inch chef's knife (I use Wüsthof) paired with a cutting board (like John Boos Maple) makes quick work of the flank steak. For broccoli, a serrated knife helps cut through stems cleanly.
Pro tip: Freeze your cutting board for 15 minutes before slicing—it creates a temporary razor edge for cleaner cuts. A measuring tape comes in handy for checking slice thickness against the grain.
Sauce Thickening
The cornstarch slurry requires quick, even mixing. A small whisk (like Norpro) ensures no lumps form in your sauce. For precise measurements, a digital scale helps when converting cornstarch from tablespoons to grams.
I also keep a small saucepan nearby to reheat any leftover sauce—just add 1 tablespoon water and simmer for 1 minute to restore thickness. A fine-mesh strainer helps remove any stray sesame seeds if you prefer a smoother sauce. 💫
Nutrition facts
Frequently asked questions
Why does slicing flank steak against the grain make it more tender?
Slicing against the grain shortens the muscle fibers, making each bite easier to chew and more tender. Flank steak has long muscle fibers that run lengthwise—cutting perpendicular creates smaller, more manageable pieces that break down faster during cooking. For this recipe, aim for ¼-inch thick slices to ensure melt-in-your-mouth texture.
Can I substitute flank steak with another cut?
Yes, but texture will differ. Sirloin or ribeye work well but may be less tender without proper slicing. Flank steak is ideal because its lean yet flavorful profile benefits from quick, high-heat cooking. For a tougher cut like skirt steak, marinate for 4+ hours instead of 30 minutes.
How do I fix overcooked broccoli in the stir-fry?
If broccoli turns mushy, remove it immediately and replace with fresh florets. To salvage slightly overcooked pieces, toss them with 1 tsp toasted sesame oil and a pinch of salt—they’ll regain some texture. For future attempts, stir-fry broccoli for only 2-3 minutes over high heat and avoid overcrowding the pan.
What’s the best way to reheat leftovers?
Reheat in a skillet over medium-high heat for 2-3 minutes with a splash of water to restore moisture. Avoid microwaving—it makes the beef rubbery. For extra crispiness, sear the beef again briefly after reheating. Leftovers keep well for 3-4 days in the fridge, but the sauce thickens when chilled—add 1 tbsp water when reheating.
Can I make this dish gluten-free?
Yes! Replace soy sauce with tamari or coconut aminos (use ⅓ more for flavor). Ensure cornstarch is gluten-free (or use arrowroot powder instead). Double-check sesame oil and rice for hidden gluten. The flavor balance will be slightly different but still delicious.
