Ingredients for beef and broccoli recipe made with lau
Restaurant-quality beef and broccoli relies on these carefully selected ingredients for umami depth and perfect texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 ½ lb | Thinly sliced against grain |
| Fresh Broccoli 🥦 | 1 ½ lb | Cut into florets, stems peeled |
| Lau (Fermented Soybean Paste) 🥫 | ¼ cup | Asian market brand preferred |
| Light Soy Sauce 🍶 | ½ cup | Kikkoman or similar |
| Dark Soy Sauce 🍶 | 1 tbsp | For color depth |
| Sesame Oil 🫒 | 2 tbsp | Toasted, for aroma |
| Fresh Ginger 🌿 | 2 tbsp | Finely minced |
| Garlic Cloves 🧄 | 6 cloves | Minced, aromatic base |
| Honey 🍯 | 1 tbsp | For sauce balance |
| Cornstarch 🌾 | 1 tbsp | For sauce thickening |
| Vegetable Oil 🫒 | ½ cup | High smoke point |
| Green Onions 🧅 | ¼ cup | Sliced, for garnish |
| Sesame Seeds 🌰 | 1 tbsp | Toasted, for texture |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |

The flank steak is non-negotiable for this dish—its lean yet tender texture sears beautifully while staying juicy. Look for well-marbled cuts at specialty butchers or Asian markets; Costco often carries pre-sliced options that save time. Fresh broccoli should be vibrant green with tight florets—avoid pre-cut bags, as they lose crunch quickly. For lau, Asian grocery stores carry the best quality; brands like Lee Kum Kee or Hinode are reliable choices. The ginger and garlic should be fresh—no powdered substitutes here, as they lack the aromatic complexity this dish demands.
No flank steak? Sirloin or ribeye work in a pinch, but slice thinner than usual. Substituting lau? Double the amount of miso paste or use 1 tbsp soy sauce + 1 tsp fish sauce as a makeshift alternative. For the broccoli, baby broccoli holds up better to high heat than large florets. The sesame oil is purely for aroma—add it at the end, not during cooking. If you're short on time, pre-cut the beef and broccoli while the sauce simmers, but don't slice them too small or they'll turn mushy.
Store the lau in the refrigerator for up to 6 months once opened, though it's best used within 3 months for peak flavor. Fresh ginger keeps for 2-3 weeks in the fridge, while garlic lasts 1 month unpeeled. The prepped beef and broccoli can be refrigerated for 24 hours before cooking, but work with them freshest for that signature wok-fired crunch. This dish reheats beautifully—stir-fry again over high heat for 2-3 minutes to restore texture, adding a splash of water if needed.

Step-by-step instructions for wok-fired beef and broccoli
Master this classic dish where tender beef meets crisp-tender broccoli in a rich, aromatic lau sauce.
Prepare the Beef and Broccoli
Slice the 1.5 lb flank steak thinly against the grain using a sharp knife. This ensures tender bites that cook quickly in the wok. Pat the slices dry with paper towels—moisture prevents proper searing. In a separate bowl, toss the 1.5 lb fresh broccoli florets with 1 tsp salt and 0.5 tsp black pepper. Let both sit at room temperature for 15 minutes while you prep the sauce.
For the broccoli, focus on even-sized florets—this guarantees consistent doneness. The salt draws out excess moisture, which helps achieve that signature wok-fried crunch. Keep the beef and broccoli separate until ready to cook, as they require different timing in the wok.
Create the Lau Sauce Base
In a small bowl, combine the 0.25 cup lau (fermented soybean paste), 0.5 cup light soy sauce, 1 tbsp dark soy sauce, 1 tbsp honey, and 1 tbsp cornstarch. Whisk vigorously until smooth—this paste forms the foundation of your sauce. In a separate bowl, mix 2 tbsp sesame oil, 2 tbsp finely minced fresh ginger, and 6 cloves minced garlic. Set both mixtures aside.
The lau provides that deep, umami richness while the dark soy sauce adds color. The cornstarch acts as a natural thickener, ensuring your sauce clings beautifully to the beef and broccoli. This two-part preparation allows you to build layers of flavor without overpowering the natural taste of the ingredients.
Wok-Fry the Beef
Heat a wok or large skillet over high heat until smoking, then add 0.5 cup vegetable oil. Once shimmering, add the beef in a single layer—don't overcrowd. Let it sear undisturbed for 2-3 minutes until deeply browned on one side. Flip and cook another 1-2 minutes until just cooked through. Remove beef and set aside, reserving any rendered fat in the wok.
High heat is critical here—it creates that signature wok-fried texture. If the beef releases easily from the pan, it's ready. Overcooking will make it tough, so work quickly. The residual fat in the wok will help build your sauce's depth of flavor.
Cook the Broccoli and Finish the Sauce
Return the wok to high heat, adding the broccoli in batches if needed. Stir-fry for 3-4 minutes until bright green and just tender-crisp. Add the ginger-garlic mixture and stir for 30 seconds until fragrant. Pour in the lau sauce mixture and stir vigorously for 1-2 minutes until the sauce thickens and coats the broccoli.
The broccoli should retain its vibrant color and slight crunch—this indicates perfect timing. The sauce should coat the back of a spoon when ready. If it thickens too quickly, add 1-2 tablespoons hot water to adjust consistency. The ginger and garlic infuse their aromatic qualities during this final cooking stage.
Combine and Garnish
Return the beef to the wok, tossing gently to coat everything in the sauce. Cook for an additional 1 minute to ensure even distribution. Transfer to serving plates and garnish with 0.25 cup sliced green onions and 1 tbsp toasted sesame seeds. Serve immediately with steamed rice to soak up every last bit of flavor.
This dish shines when served fresh—each bite should deliver tender beef, crisp broccoli, and a perfectly balanced lau sauce. The sesame seeds add a delightful textural contrast, while the green onions provide a fresh finish. The combination of wok-fried textures and rich umami flavors makes this a restaurant-quality dish you can recreate at home.

Make-ahead tips for leftovers
Prep Ahead Sauce
Make the lau sauce 24 hours in advance—it develops deeper flavor when rested. Store it in an airtight container in the fridge. When ready to cook, simply whisk it again to smooth out any separation.
The cornstarch will thicken even more after chilling, so add 1 tsp water if needed before using. This step saves you 10 minutes of prep time during the actual cooking process. 💡
Partial Cook Broccoli
Blanch the broccoli florets in boiling water for 1 minute, then shock in ice water. Pat dry completely and store in an airtight container for up to 2 days.
When cooking, stir-fry for just 2 minutes to restore crispness—this method preserves texture perfectly. I find this especially helpful when hosting dinner parties. ✨
Marinate the Beef
Slice the beef as directed, then marinate in 2 tbsp soy sauce, 1 tbsp honey, and 1 tsp cornstarch for 1-2 hours before cooking. This tenderizes the meat and infuses flavor.
Store marinated beef in a ziplock bag in the fridge. When ready to cook, simply pat dry—no need to rinse. The marinade also helps prevent sticking during searing. 🥩
Freezer-Friendly Components
Both the beef and broccoli can be prepped and frozen separately for up to 3 months. Use freezer-safe bags with labels noting contents. When ready to cook, thaw overnight in the fridge, then pat dry thoroughly.
Freezing works best for the beef—just add 1 extra minute to the searing time to account for any moisture loss. 🧊
Sauce Adjustments
If you're short on time, prepare the sauce ingredients separately and store them in small containers in the fridge. Combine only when ready to cook—this keeps the lau fresh and prevents premature thickening.
For extra convenience, pre-mince the ginger and garlic, storing them in ice cube trays with water. Freeze, then pop out as needed. 🌿
Reheating Leftovers
Reheat beef and broccoli in a skillet over medium-high heat for 3-4 minutes, adding 1 tbsp water to prevent sticking. For best results, stir-fry the broccoli separately first, then add the beef to warm through.
The lau sauce may thicken further—thin with 1 tsp water if needed. This method restores the wok-fried texture beautifully. 🔥

Frequently asked questions
What exactly is lau and where can I find it?
Lau is a fermented soybean paste that adds deep umami flavor to this dish. You'll find it in the Asian foods section of most grocery stores, often labeled as "fermented soybean paste" or "lau gan." Brands like Lee Kum Kee or Hinode work best. If unavailable, substitute with 1 tbsp miso paste + 1 tsp fish sauce for similar depth of flavor.
Can I use a different cut of beef instead of flank steak?
Yes! Sirloin or ribeye work well, but slice them thinner than flank steak since they're more tender. For leaner cuts like top round, marinate for 2-3 hours first to prevent dryness. The key is thin, even slices that cook quickly in the wok—aim for ¼-inch thickness maximum.
How do I prevent the broccoli from turning mushy?
Keep florets similar in size (about 1-inch diameter) so they cook evenly. Stir-fry over high heat for exactly 3-4 minutes—don't overcrowd the pan. For extra insurance, blanch broccoli for 1 minute in boiling water before stir-frying to jumpstart cooking.
Is this recipe gluten-free?
Not traditionally, but you can adapt it! Replace regular soy sauce with tamari or coconut aminos, and use gluten-free cornstarch. The lau itself typically contains gluten, so check the label—some brands offer gluten-free versions. For a complete GF version, substitute lau with 1 tbsp coconut miso + 1 tsp gluten-free fish sauce.
What's the best way to reheat leftovers?
Reheat in a skillet over medium-high heat for 3-4 minutes, adding 1 tbsp water to prevent sticking. For best texture, stir-fry broccoli first (2 minutes), then add beef to warm through. The lau sauce may thicken—thin with ½ tsp water if needed. Microwaving works in a pinch, but texture suffers.
