Ingredients for beef and broccoli udon stir fry
Five core ingredients transform into a restaurant-worthy stir fry with silky noodles and umami crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Udon Noodles 🍜 | 8 oz | Fresh or dried, cut into 4-inch pieces |
| Flank Steak 🥩 | 1 lb | Thinly sliced against grain |
| Broccoli Florets 🥦 | 2 cups | Cut into bite-sized pieces |
| Fresh Ginger 🌿 | 1 tbsp | Finely grated, fresh preferred |
| Soy Sauce 🍶 | ½ cup | High-quality, preferably Japanese |
| Sesame Oil 🫒 | 1 tbsp | Toasted, for aroma |
| Honey 🍯 | 1 tbsp | Light, for balance |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Green Onions 🧅 | 3 whole | Sliced, for garnish |
| Sesame Seeds 🥜 | 1 tbsp | Toasted, for garnish |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point for stir-frying |
| Cornstarch 🌾 | 1 tbsp | For beef marinade |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
The flank steak is your secret weapon here—it needs to be sliced thinly against the grain for that perfect tender bite. Costco or your local butcher shop will have it pre-sliced, but if you're doing it yourself, freeze the meat for 20 minutes first to make slicing easier. For broccoli, fresh florets are ideal, but frozen works in a pinch—just blanch them for 30 seconds to keep that crisp texture. Udon noodles? Fresh is best, but dried holds up fine if you soak them properly. Look for udon with a smooth, glossy appearance—Trader Joe's or Asian markets carry great options.
No flank steak? Sirloin or ribeye work too, but they won't be as tender. Fresh ginger? Dried works at half the amount, but it lacks that bright punch. The soy sauce is non-negotiable—Japanese brands like Kikkoman or Yamasa deliver the best umami. For a sweeter touch, swap the honey for maple syrup or agave**. Sesame oil is all about aroma—don't cook with it, just add it at the end. The cornstarch marinade is key for that signature wok-tossed texture—don't skip it!
This dish reheats like a dream—3-4 days in the fridge, 2 months frozen. Double the batch and freeze half for lazy weeknights. Garnish with toasted sesame seeds and sliced green onions right before serving—that's the restaurant-quality touch**. Store the sauce separately if you're prepping ahead, then toss it in just before eating. The noodles can be pre-cooked and refrigerated for up to 2 days, but cook them fresh if you can—trust me on this!

Step-by-step instructions for beef and broccoli udon stir fry
Here's how to create a restaurant-worthy stir fry with perfectly silky udon and tender beef.
Prepare the Udon Noodles for Maximum Texture
Bring a large pot of water to a rolling boil and add the 8 oz udon noodles. Cook according to package instructions until al dente—usually about 4-5 minutes for fresh udon. The noodles should be tender but still retain a slight bite.
Drain immediately and rinse briefly under cold water to stop the cooking process. Toss the noodles with 1 tablespoon sesame oil and set aside. This prevents them from sticking and adds a subtle nutty aroma. I like to keep them separate until the very end to maintain their silky texture in the final dish.
Marinate and Sear the Flank Steak
In a small bowl, combine 1 tablespoon cornstarch, 0.5 teaspoon salt, and 0.25 teaspoon black pepper. Add the 1 lb flank steak and toss to coat evenly. Let it marinate for 15-20 minutes at room temperature—this ensures even cooking and maximum tenderness.
Heat 2 tablespoons vegetable oil in a wok or large skillet over high heat until shimmering. Add the steak in a single layer and sear for 2-3 minutes per side until deeply browned with a caramelized crust. Remove and set aside—this initial sear locks in juices while building deep flavor.
Stir-Fry the Broccoli and Aromatics
In the same wok, reduce heat to medium-high and add 2 cups broccoli florets. Stir-fry for 2-3 minutes until bright green and just tender-crisp—you want them to retain their snap. Add the 4 cloves minced garlic and 1 tablespoon grated fresh ginger, cooking for 30 seconds until fragrant.
Pour in the 0.5 cup soy sauce and 1 tablespoon honey, stirring constantly. Let it simmer for 1 minute until slightly reduced. The sauce should coat the back of a spoon—this creates the perfect balance of salty and sweet that defines this dish.
Combine Everything for the Final Toss
Return the seared steak to the wok along with any accumulated juices. Add the prepared udon noodles and toss vigorously for 1-2 minutes until everything is evenly coated. The residual heat will finish cooking the noodles perfectly while infusing them with the beef's rich flavors.
Drizzle with 1 tablespoon toasted sesame oil and garnish with 3 sliced green onions and 1 tablespoon toasted sesame seeds. Serve immediately while hot—this stir fry tastes best straight from the wok when the noodles are silky and the beef is still juicy.
Pro Tips For Making Beef And Broccoli Udon Stir Fry
- SEAR THE BEEF FAST: High heat is your friend here—get that flank steak screaming hot for 2-3 minutes per side until it’s deep brown, not just pink. I used to rush this, and the beef ended up chewy; now I let it sit untouched until the pan is actually smoking.
- CUT BROCCOLLI SMALLER THAN YOU THINK: Even florets need to be halved or quartered—think rice-sized pieces. Big chunks stay crunchy while the noodles soften; you’ll end up with a mix of textures instead of a cohesive stir-fry.
- DON’T BOIL UDON—SOAK: Toss dry udon into a bowl of boiling water for 2-3 minutes, then drain. Boiling them fully turns them mushy; this method keeps them chewy and ready to absorb the sauce without falling apart.
- SAVE THE GINGER WATER: After grating ginger, squeeze out the juice and reserve the liquid—it’s packed with flavor. Stir a teaspoon into the sauce at the end; it adds brightness without overpowering the beef and broccoli.
Serving suggestions for leftovers
Garnish Like a Pro
Toast 1 tablespoon sesame seeds in a dry skillet over medium heat for 1-2 minutes until golden and fragrant. Sprinkle them over the finished dish right before serving—they add a nutty crunch that contrasts beautifully with the silky noodles.
I also like to add 3 sliced green onions for a fresh, bright pop of color that cuts through the richness. 🌟
Rice Pairing
Serve with steamed jasmine rice or short-grain sushi rice on the side to soak up any extra sauce. I recommend Trader Joe's jasmine rice because it's light and fluffy. For a more authentic experience, try Japanese short-grain rice—its sticky texture pairs perfectly with the udon noodles. 🍚
Protein Boost
Add a fried egg on top for extra protein and richness—just crack it into the wok during the final toss. The runny yolk will coat the noodles with extra flavor. For a vegetarian twist, swap beef for extra-firm tofu pressed and pan-fried until crispy. 🍳
Sauce Variations
For a spicier kick, add ½ teaspoon chili flakes or 1 teaspoon sriracha to the sauce. If you prefer it sweeter, increase the honey to 2 tablespoons**. For a tangy twist, stir in 1 teaspoon rice vinegar at the end. 🌶️
Presentation Tips
Use a wide, shallow bowl to serve this dish—it lets everyone see the vibrant colors and textures. Garnish with an extra drizzle of sesame oil and a sprinkle of sesame seeds for that restaurant-quality finish.
For a fun touch, arrange the beef strips in a circular pattern on top of the noodles. ✨

Frequently asked questions
Can I use dried udon noodles instead of fresh?
Yes! Dried udon works perfectly—just soak them in hot water for 5-7 minutes until pliable, then drain and rinse with cold water. The key is to cook them slightly less than package instructions since they'll finish cooking in the wok. For extra texture, cut them into 4-inch pieces before cooking.
Why does my beef turn out chewy instead of tender?
This usually happens when you don't slice against the grain or overcook the meat. Always cut flank steak thinly against the grain (freeze it 20 minutes first for easier slicing) and cook for only 2-3 minutes per side on high heat. The cornstarch marinade also helps tenderize—don't skip it!
How do I adjust the sauce for spicier or sweeter preferences?
For heat, add ½ teaspoon chili flakes or 1 teaspoon sriracha to the sauce. For sweetness, increase honey to 2 tablespoons or swap for maple syrup. The base recipe balances umami and sweetness perfectly, but these tweaks let you customize. Taste as you go!
Can I make this dish ahead of time?
Store components separately: cooked udon (up to 2 days refrigerated), seared beef (3 days), and sauce (5 days). Reheat everything separately over medium heat, then toss together with fresh sesame oil. Garnish just before serving for best texture.
What's the best way to reheat leftovers?
Spread leftovers on a plate and microwave for 1-2 minutes with a damp paper towel to restore moisture. For stovetop, heat in a wok with ½ tablespoon oil** over medium heat, adding a splash of water to prevent sticking. The noodles will soften slightly but still taste great.
