Beef and Broccoli Recipe With London Broil: Wok-Heated Crunch and Silky Florets

This beef and broccoli recipe with London broil delivers restaurant-quality results at home, combining tender, seared beef with perfectly crisp-tender broccoli and a rich, savory sauce. The high-heat sear on the London broil creates a caramelized crust that locks in juices, while the broccoli achieves that coveted wok-hei—smoky, slightly charred edges with silky florets. I developed this recipe after years of testing, ensuring every element comes together in harmony for a dish that's both impressive and foolproof.

The secret to achieving professional results lies in the technique: a quick marinade enhances the beef's natural flavors, while high-heat searing ensures a perfect crust.

Ingredients for beef and broccoli recipe with london broil

London broil and broccoli crowns form the perfect duo for this restaurant-style dish.

The London broil is the star here—center-cut slices create that perfect caramelized crust while staying juicy inside. Costco or Whole Foods carry the best cuts, but any butcher can slice it for you if you buy a whole piece. Fresh broccoli crowns are ideal (the florets stay intact better than chopped), but regular broccoli works if you trim the stems. For the ginger, freshly grated makes all the difference—jarred paste tastes flat. The garlic should be minced, not pressed—that way you control the texture better.

No sesame oil? Avocado oil works in a pinch, though it lacks the nutty aroma. Substitute brown sugar with honey or maple syrup, but reduce by half since it's sweeter. The soy sauce can be regular, but low-sodium gives you better control over saltiness. For the broccoli, blanching in boiling water for 30 seconds before searing ensures crisp-tender results. The cornstarch is key for that glossy sauce—don't skip it. If you're short on time, pre-cut broccoli from Trader Joe's saves chopping work.

Marinate the beef for at least 30 minutes—up to 4 hours in the fridge. Broccoli keeps 5-7 days in the fridge, but best used within 3 days for peak texture. The sauce thickens as it cools, so reheat gently with a splash of water if needed. Portion leftovers into airtight containers—the beef stays tender for 3 days in the fridge, while the sauce freezes beautifully for 3 months. Garnish with sesame seeds and scallions right before serving for maximum freshness.

Step-by-step instructions for beef and broccoli with London broil

A perfect balance of tender beef and crisp-tender broccoli awaits—here's how to achieve wok-heated perfection.

Slice the 1.5 lb London Broil against the grain into ½-inch thick strips—this ensures tender bites. In a bowl, combine the sliced beef with 0.5 cup low-sodium soy sauce, 1 tbsp brown sugar, 1 tbsp rice vinegar, 1 tbsp sesame oil, 1 tsp kosher salt, and 0.5 tsp black pepper. Mix well to coat evenly, then let it marinate for at least 20 minutes (up to 2 hours in the fridge for deeper flavor). The beef should absorb the marinade completely, developing a glossy sheen.

While the beef marinates, trim the 1.5 lb fresh broccoli crowns into large florets, keeping the stems intact for structure. Blanch the broccoli in boiling water for 1 minute, then immediately plunge into ice water to halt cooking. This preserves vibrant color and slight crunch. Drain well and set aside—your broccoli is now ready for the wok.

Heat a wok or large skillet over high heat until smoking, then add 2 tbsp extra-virgin olive oil. Working in batches (to avoid overcrowding), add the marinated beef and sear for 2-3 minutes per side until deep brown and nearly cooked through. The beef should release easily from the pan—this indicates proper doneness. Transfer to a plate and tent with foil to keep warm.

Real talk: Don't rush this step. High heat creates that signature wok-heated crust, while proper searing locks in juices. If your pan isn't hot enough, the beef will steam instead of sear. You'll know it's ready when the edges are golden brown and the beef pulls away cleanly.

Return the wok to high heat and add 6 minced garlic cloves and 1 tbsp finely grated fresh ginger. Stir-fry for 30 seconds until fragrant—this releases their aromatic oils. Add the blanched broccoli and stir-fry for 2-3 minutes until heated through but still crisp-tender. The broccoli should retain its bright green color and slight bite.

In a small bowl, whisk together 1 tbsp cornstarch with 2 tbsp water to create a slurry. Pour this into the wok along with any accumulated juices from the beef. Stir constantly for 1-2 minutes until the sauce thickens to a glossy, coatable consistency. The sauce should cling to the back of a spoon when lifted.

Return the seared beef to the wok and toss gently to coat everything in the sauce. Cook for 1 minute to ensure even distribution and proper heating. The beef should now be fully cooked through with a silky-smooth sauce clinging to both the beef and broccoli.

Remove from heat and transfer to serving plates. Garnish with 4 sliced green onions (white and green parts) and 1 tbsp toasted sesame seeds for added texture and aroma. Serve immediately over steamed rice to soak up every delicious bite of the sauce.

Common mistakes when making great beef and broccoli recipe with london broil

Over-Marinating Beef

The London broil absorbs marinade quickly, but marinating longer than 2-3 hours can make the beef mushy. I've ruined perfectly good beef by leaving it in marinade overnight—don't make my mistake! The ideal marinating time is 30-60 minutes for maximum flavor without compromising texture. Pat the beef dry before searing to ensure a proper crust. 🥩

Skipping the Blanch

Blanching broccoli for 1 minute before stir-frying is non-negotiable for that signature crisp-tender texture. Without blanching, broccoli turns mushy from the high heat. For best results, use ice water to shock the broccoli immediately after boiling—this halts cooking and preserves vibrant color. I've seen home cooks skip this step and end up with sad, limp broccoli. 🥦

Overcrowding the Pan

Adding all the beef to the pan at once causes steaming instead of searing. Work in batches of 2-3 slices to maintain high heat and achieve that beautiful caramelized crust. A crowded pan also lowers the internal temperature, leading to tough beef. I use a 12-inch cast iron skillet for this recipe—it's wide enough to handle batches without overcrowding. 🔥

Undercooking the Beef

London broil should reach 145°F internal temperature for medium-rare, but many home cooks pull it too soon. Use a meat thermometer to check—insert it at the thickest part. The beef will carry over to 150°F while resting, so pull it when it's 5°F below your target doneness. I've had guests complain about dry beef because I didn't let it rest long enough. 🌡️

Sauce Too Thin

The cornstarch slurry is what gives the sauce its signature glossy texture. If your sauce is too thin, don't just add more cornstarch—whisk it with water first to create a proper slurry. I've seen people add dry cornstarch directly to the pan, which creates lumps. For best results, whisk 1 tbsp cornstarch with 2 tbsp water before adding to the pan. The sauce should coat the back of a spoon when finished. 🥄

Using Wrong Equipment

A wok is ideal for this dish, but a heavy-bottomed skillet works too. Avoid non-stick pans—they can't handle the high heat needed for proper searing. I use my All-Clad stainless steel wok for authentic wok-hei, but a Lodge cast iron skillet is a great budget alternative. The key is maintaining high heat throughout the cooking process. 🍳
