Soups & Stews
This beef and broccoli recipe made with lau transforms a classic stir-fry into a restaurant-quality dish with just one secret ingredient. The fermented bean paste—whether traditional lau or chili bean sauce—adds that signature umami depth that separates home cooking from takeout. I first discovered its magic while adapting Chinese-American recipes, and it became the game-changer for my stir-fry repertoire.
The technique is simple but precise: sear thinly sliced beef until caramelized, then stir-fry crisp-tender broccoli before combining everything with the lau-based sauce. Garlic, ginger, and a touch of oyster sauce elevate the flavors without overpowering the fermented bean paste's complexity.
The result? A dish that's savory, slightly sweet, and packed with that irresistible umami punch.
What makes this recipe stand out is how the lau transforms ordinary ingredients into something extraordinary. The sauce caramelizes slightly as it coats the beef and broccoli, creating a glossy, flavorful crust that clings to every bite.
Serve it over steamed rice or noodles for the full experience—each forkful delivers that perfect balance of textures and flavors.
Whether you're making this for a weeknight dinner or a special occasion, the lau ensures depth of flavor that's hard to replicate. The best part? It comes together in under 30 minutes, making it the perfect solution for a quick yet impressive meal. Let's get cooking!
Ingredients for beef and broccoli recipe made with lau
This umami-packed stir-fry transforms ordinary ingredients into a restaurant-worthy dish with just one secret ingredient.
| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 lb | Thinly sliced against grain |
| Fresh Broccoli Crowns 🥦 | 2 cups | Cut into bite-sized florets |
| Lau (Fermented Bean Paste) 🧂 | 3 tbsp | Traditional or chili bean sauce |
| Garlic Cloves 🧄 | 4 cloves | Minced, aromatic |
| Fresh Ginger 🌿 | 1 tbsp | Grated, finely |
| Oyster Sauce 🍶 | 2 tbsp | High-quality, rich flavor |
| Sesame Oil 🫒 | 1 tbsp | Toasted, for aroma |
| Soy Sauce 🥄 | 1 tbsp | Light or dark preferred |
| Honey 🍯 | 1 tbsp | For subtle sweetness |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point |
| Green Onions 🧅 | 3 whole | Sliced, for garnish |
| Sesame Seeds 🌾 | 1 tsp | Toasted, for crunch |

The lau is non-negotiable—this fermented bean paste is the umami bomb that elevates everything. Find it in the Asian aisle of stores like Whole Foods or H Mart, or order online if your local market doesn't carry it. Traditional lau has a deeper, funkier flavor than chili bean sauce, but both work—just adjust to taste. Flank steak is ideal for stir-fry because it slices thinly and stays tender. Ask your butcher to slice it against the grain if you're not doing it yourself. Fresh ginger and garlic? Buy organic if possible—the brighter the color, the fresher the flavor. For broccoli, look for bright green crowns with tight florets—they'll stay crispier during stir-frying.
No lau? Miso paste or hoisin sauce can mimic some of the depth, though nothing quite matches its complexity. Swap the honey for maple syrup if you prefer, or use agave for a neutral sweetness. Running low on sesame oil? Toast a few sesame seeds in a dry pan and use their oil instead—it's still aromatic, just less concentrated. The oyster sauce can be tricky; Lee Kum Kee is the gold standard, but any high-quality brand works. If you're avoiding oyster sauce entirely, soy sauce plus a splash of mirin gets you close. And for the broccoli? Blanch it for 30 seconds first if you're worried about sogginess—it'll hold up better to the stir-fry.
Prep ahead to save time: Slice the steak and broccoli the night before and store in airtight containers. The lau and sauce components keep for 3 months in the fridge, so make extra if you're feeding a crowd. Leftover beef and broccoli? Store in a sealed container for up to 4 days—it reheats beautifully. For the rice, use a rice cooker or 1:1.5 water-to-rice ratio if cooking on the stovetop. And if you're serving this for company, garnish with toasted sesame seeds and green onions right before serving—it makes all the difference for presentation.

Step-by-step instructions for beef and broccoli with lau sauce
Here's how to create restaurant-quality beef and broccoli using lau for that signature umami depth.
Prepare the Flank Steak for Maximum Tenderization
Slice the 1 lb flank steak thinly against the grain into ¼-inch thick strips. This is crucial—cutting against the grain shortens the muscle fibers, making each bite more tender. Place the sliced steak in a bowl and season generously with 1 tsp salt and 0.5 tsp black pepper, tossing to coat evenly. Let it sit at room temperature for 15-20 minutes while you prep the rest. This resting period ensures even cooking and prevents tough, cold centers.
While the steak rests, toast the 1 tsp sesame seeds in a dry skillet over medium heat for 2-3 minutes until fragrant and golden. Remove them immediately and set aside for garnish. This quick step adds nutty aroma that elevates the dish. Keep the toasted seeds in a small bowl—they'll be our finishing touch.
Create the Lau-Based Stir-Fry Sauce
In a small bowl, combine the 3 tbsp lau, 2 tbsp oyster sauce, 1 tbsp soy sauce, 1 tbsp honey, 1 tbsp toasted sesame oil, 1 tbsp grated fresh ginger, and 4 cloves minced garlic. Mix thoroughly with a fork until the lau is fully incorporated and the sauce is smooth. The lau should dissolve completely—if it's too thick, add 1 teaspoon water at a time until it reaches a pourable consistency. This sauce is the heart of our dish, delivering that signature fermented bean depth.
Let the sauce sit for 5 minutes while you prepare the vegetables. This resting period allows the flavors to meld together, creating a cohesive umami-rich base. The ginger and garlic will infuse the sauce with aromatic complexity, while the honey adds just enough sweetness to balance the savory elements.
Stir-Fry the Broccoli to Perfect Texture
Heat 2 tbsp vegetable oil in a wok or large skillet over high heat until shimmering. Add the 2 cups fresh broccoli crowns and stir-fry for 3-4 minutes until the florets are vibrant green and just beginning to soften at the edges. The high heat is key here—you want to preserve the broccoli's color and crisp texture. Don't overcrowd the pan, or the steam will turn them mushy.
Remove the broccoli to a plate and set aside. Immediately add the sliced green onions to the same pan, stirring for 30 seconds until fragrant. The green onions will add a fresh, bright contrast to the rich beef and saucy broccoli. Keep them separate from the broccoli for now—they'll be our garnish.
Cook the Steak to Perfect Doneness
Working in batches if needed, add the seasoned steak strips to the hot wok in a single layer. Cook undisturbed for 1-2 minutes until the edges are deeply browned and the steak develops a beautiful sear. This initial sear locks in juices and creates that signature caramelized flavor. Once browned, stir the steak for another 30-45 seconds until just cooked through—it should reach 145°F internally. Overcooking will make it tough.
Remove the steak to a clean plate and set aside. The residual heat will carry it to perfect doneness while you finish the dish. Here's where the magic happens: add the prepared lau sauce to the wok and stir vigorously to scrape up all the delicious browned bits from the bottom. These bits, called fond, are packed with flavor that will elevate your entire dish.
Combine and Finish with Perfect Garnish
Return the steak and broccoli to the wok, tossing everything together with the sauce until everything is evenly coated. Cook for another 1-2 minutes until the broccoli is heated through and the sauce has thickened slightly to cling to the ingredients. The dish should be vibrant, with glossy steak and bright green broccoli. If the sauce is too thick, add 1 tablespoon water to loosen it.
Divide the 1.5 cups cooked white rice among serving plates, then spoon the beef and broccoli mixture over the top. Garnish each serving with the toasted sesame seeds and sliced green onions. The contrast of textures and colors makes this dish visually stunning, while the balance of umami, sweetness, and freshness creates a harmonious flavor profile that's truly memorable.
Pro Tips For Making Beef And Broccoli Recipe Made With Lau
- Slice Against the Grain: Flank steak’s tough fibers run parallel to the grain—cutting perpendicular ensures every bite melts like butter. Use a sharp knife, angle it low, and slice after resting (yes, even if you’re impatient like me).
- Toast the Lau: Spread a thin layer of lau on a dry pan and toast it over medium heat for 30 seconds until fragrant. This deepens its nutty, fermented flavor—skip this, and your sauce will taste flat.
- Blanch Broccoli First: Drop broccoli crowns into boiling water for 30 seconds, then shock in ice water. This keeps them vibrant and prevents them from turning mushy when they hit the hot wok later.
- Use Two Stages for Heat: Sear the beef in a screaming-hot pan until deeply browned, then lower to medium-low to finish cooking. Rushing the second stage leaves the meat dry; patience here locks in juices.

Frequently asked questions
What's the difference between lau and chili bean sauce?
Lau is a traditional fermented bean paste with a deeper, funkier flavor and more complex umami profile. Chili bean sauce is sweeter and slightly spicier, often containing red chili flakes. For this recipe, traditional lau gives the most authentic depth, but chili bean sauce works in a pinch—just reduce honey to ½ tbsp to balance the sweetness.
Can I substitute flank steak with another cut? Flank steak is ideal for its tenderness, but sirloin or ribeye work well too. Just slice against the grain for maximum tenderness. For a leaner option, try lean beef tenderloin—it's more expensive but incredibly tender.
Why does my lau sauce get too thick?
This happens when the lau isn't fully dissolved or the sauce reduces too much. Always whisk the lau with warm water first to create a smooth paste. If it thickens during cooking, add 1 tbsp water at a time until it reaches a glossy, pourable consistency. The sauce should coat the back of a spoon but still flow easily.
How do I make this dish spicier?
Add ½ tsp red pepper flakes to the stir-fry sauce or sprinkle 1 tsp sriracha at the end. For heat lovers, mix 1 tbsp gochujang (Korean chili paste) into the lau sauce before cooking. Adjust to taste—start with less and add more gradually.
Can I make this recipe ahead of time?
Yes! Cook the beef and broccoli, then store in an airtight container for up to 4 days in the fridge. Reheat gently in a skillet with 1 tsp sesame oil to restore texture. For best results, reheat only what you need—leftover portions can dry out. The flavors actually improve overnight!
