Jump to RecipeWhy This Recipe Works
It keeps the process simple while maximizing flavor. The sauce leans on soy, brown sugar or honey, and a few aromatics, so it tastes bold without needing a long simmer.
Slicing the beef thinly lets it cook quickly and stay tender. Broccoli goes in near the end so it stays bright and crisp-tender. And using noodles instead of rice means everything cooks and mixes in one pan.

How to Make It
- Prep the beef. Freeze the beef for 15–20 minutes to firm it up if you have time.Slice it thinly across the grain. Pat dry and season lightly with salt and pepper.
- Mix the teriyaki sauce. In a bowl, whisk soy sauce, water or broth, brown sugar or honey, rice vinegar, sesame oil, and sriracha if using. In a separate small cup, stir cornstarch with 2 tablespoons of cold water to make a slurry.Set both aside.
- Cook the noodles. Boil according to package directions until just al dente. Reserve 1/4 cup of the starchy cooking water, then drain and set aside. Toss with a teaspoon of oil to prevent sticking.
- Blanch or steam the broccoli. In the last 2 minutes of the noodle cooking time, add fresh broccoli florets to the pot.If using frozen broccoli, thaw and pat dry. Drain with the noodles or steam separately until crisp-tender.
- Stir-fry the aromatics. Heat 1–2 tablespoons oil in a large skillet or wok over medium-high heat. Add garlic and ginger.Stir for 20–30 seconds until fragrant, being careful not to burn.
- Cook the beef. Increase heat to high. Add the beef in a single layer. Sear for 1–2 minutes per side until just cooked through and slightly browned.Work in batches if needed to avoid steaming.
- Add the sauce. Pour the teriyaki mixture into the pan. Once it begins to bubble, whisk in the cornstarch slurry. Stir continuously for 30–60 seconds until the sauce thickens and turns glossy.
- Toss with noodles and broccoli. Add the drained noodles and broccoli to the pan.Toss until everything is coated. If the sauce feels too thick, splash in reserved noodle water a little at a time.
- Finish and serve. Taste and adjust with more soy (salt), vinegar (brightness), or a pinch of sugar (balance). Garnish with green onions and sesame seeds.Serve hot.
20-Minute Teriyaki Beef and Broccoli Noodles
Tender beef, crisp broccoli, and chewy noodles in a glossy sweet-savoury teriyaki sauce — one pan, 20 minutes
Ingredients — Stir-Fry
- 1 lb flank steak, skirt steak, or sirloin, very thinly sliced across the grain
- 10–12 oz lo mein, udon, or spaghetti noodles
- 4 cups broccoli florets, small (fresh or thawed frozen, patted dry)
- 3 cloves garlic, minced
- 1 tbsp fresh ginger, minced or grated
- 1–2 tbsp neutral oil (canola, vegetable, or avocado)
- Salt and black pepper to taste
Ingredients — Teriyaki Sauce
- ½ cup low-sodium soy sauce
- â…“ cup water or beef broth
- 3 tbsp brown sugar or honey
- 1 tbsp rice vinegar or lime juice
- 1 tbsp sesame oil
- 1–2 tsp sriracha or chili-garlic sauce (optional, for heat)
- 2 tbsp cornstarch mixed with 2 tbsp cold water (slurry for thickening)
To Serve
- 3–4 green onions, sliced (optional)
- 1–2 tsp sesame seeds (optional)
Instructions
- Prep the Beef and SauceIf you have time, freeze the beef for 15–20 minutes to firm it up, then slice very thinly across the grain. Pat dry and season lightly with salt and pepper. In a bowl, whisk together the soy sauce, water or broth, brown sugar or honey, rice vinegar, sesame oil, and sriracha if using. In a separate small cup, stir the cornstarch and cold water into a smooth slurry. Set both aside.Mixing the sauce and slurry before you start cooking is essential — the stir-fry moves fast and there won't be time to measure at the wok.
- Cook the Noodles and BroccoliCook the noodles in salted water according to package directions until just al dente. In the last 2 minutes of cooking, add fresh broccoli florets to the pot. Reserve ¼ cup of the starchy cooking water, then drain everything together. Toss the noodles with a teaspoon of oil to prevent sticking.Cook noodles to al dente only — they will absorb more sauce when tossed in the pan and overcooked noodles go mushy quickly. Reserve the pasta water before draining; it's the best tool for adjusting sauce consistency.
- Stir-Fry the AromaticsHeat 1–2 tablespoons of oil in a large skillet or wok over medium-high heat. Add the garlic and ginger and stir for 20–30 seconds until fragrant. Don't let them brown.Garlic and ginger burn in under a minute at high heat — move quickly and have the beef ready to add immediately after.
- Sear the BeefIncrease heat to high. Add the beef in a single layer — work in batches if needed. Sear for 1–2 minutes per side until just cooked through and lightly browned. Don't stir constantly; let it sit briefly to develop colour.Crowding the pan causes the beef to steam rather than sear and gives you grey, tough meat instead of browned, tender slices. Two batches in a hot pan is far better than one crowded batch.
- Add the SaucePour the teriyaki mixture into the pan. Once it begins to bubble, give the cornstarch slurry a quick stir and whisk it in. Stir continuously for 30–60 seconds until the sauce thickens and turns glossy.Add the slurry only once the sauce is simmering — adding it to cold liquid gives you lumps rather than a smooth, even thickening. Stir the slurry right before adding as the cornstarch settles quickly.
- Toss and ServeAdd the drained noodles and broccoli to the pan. Toss until everything is evenly coated and glossy. If the sauce looks too thick, splash in reserved noodle water a little at a time. Taste and adjust with extra soy for saltiness, vinegar for brightness, or a pinch of sugar for balance. Garnish with green onions and sesame seeds and serve immediately.Serve straight away — noodles continue absorbing sauce as they sit and the dish thickens quickly. Have your bowls warm and ready before the final toss.
Tips for the Best Results
- Slice beef as thinly as possible across the grain — freezing it for 15–20 minutes firms it up and makes clean thin slices much easier.
- Mix the sauce and prepare the cornstarch slurry before you start cooking — the stir-fry moves quickly and there is no time to measure once the pan is hot.
- Sear beef in a single layer in batches — crowding the pan causes steaming rather than searing and gives you pale, tough meat.
- Cook noodles to al dente only — they absorb more sauce when tossed and will overcook further in the hot pan.
- Reserve pasta water before draining — it's the best way to adjust sauce consistency when tossing everything together.
- Pat thawed frozen broccoli very dry before adding — excess water dilutes the sauce and prevents proper tossing.
- Serve immediately — noodles keep absorbing sauce and the dish thickens quickly. Reheat leftovers in a skillet with a splash of water to loosen.
Storage Instructions
Let leftovers cool to room temperature, then store in an airtight container for up to 4 days in the fridge. Reheat gently in a skillet with a splash of water to loosen the sauce. For the microwave, cover and heat in 45-second bursts, stirring in between.
Freezing is possible for up to 2 months, but the noodles may soften slightly; thaw overnight in the fridge before reheating.

Pitfalls to Watch Out For
- Overcooking the beef: Thin slices cook in minutes. Pull them as soon as the pink is gone to keep them tender.
- Boiling the sauce too long: Once it thickens, reduce the heat. Over-reduction can make it too salty or sticky.
- Soggy noodles: Cook noodles to al dente and avoid letting them sit in water.Toss with a little oil after draining.
- Watery broccoli: Pat thawed broccoli dry. Too much moisture dilutes the sauce.
- Overcrowding the pan: Sear beef in batches if needed. Crowding leads to steaming and dull flavor.
Variations You Can Try
- Chicken or tofu: Swap beef for thinly sliced chicken breast or firm tofu cubes (press tofu first).Cook until browned before adding sauce.
- Veggie-packed: Add bell peppers, snap peas, carrots, mushrooms, or baby corn. Stir-fry quickly to keep crunch.
- Soba or rice noodles: Use buckwheat soba for a nuttier flavor or wide rice noodles for a chewier bite.
- Gluten-free: Use tamari or certified gluten-free soy sauce and rice noodles. Check all labels, including vinegar and chili sauce.
- Garlic-chili kick: Add chili crisp or extra sriracha at the end for heat and texture.
- Citrus twist: Finish with a squeeze of orange or lime juice for brightness.
- Sesame crunch: Top with toasted sesame seeds or crushed roasted peanuts.
FAQ
What’s the best cut of beef for quick stir-frying?
Flank, skirt, or sirloin work well.
Slice very thinly across the grain for tenderness. If the knife drags, partially freeze the meat first to get clean, thin slices.
Can I use store-bought teriyaki sauce?
Yes. Use about 3/4 to 1 cup, then adjust thickness with a cornstarch slurry if needed.
Taste and tweak with a splash of vinegar or lime for brightness.
How do I keep broccoli bright and crisp?
Don’t overcook it. Blanch for 1–2 minutes or steam until just tender, then transfer straight into the pan to coat with sauce. If you like extra-crisp, shock in cold water after blanching and pat dry before tossing in.
My sauce is too thin.
What should I do?
Stir another teaspoon of cornstarch into a tablespoon of cold water. Add to the simmering sauce, stir, and cook for 30–60 seconds until thickened. Go slowly to avoid over-thickening.
What noodles work best?
Lo mein or fresh udon give a classic texture.
Dried spaghetti is a great stand-in if that’s what you have. Cook just to al dente so they don’t get mushy when tossed with sauce.
Can I make this ahead?
You can slice the beef, mix the sauce, and prep the veggies up to 24 hours ahead. For the best texture, cook the noodles and stir-fry right before serving.
Leftovers still reheat well with a splash of water.
How do I make it less sweet?
Reduce the brown sugar or honey to 1–2 tablespoons and add a bit more vinegar or lime. You can also balance sweetness with extra ginger and a small pinch of black pepper.
Is there a soy-free option?
Try coconut aminos (sweeter, less salty) and adjust seasoning with salt and a squeeze of citrus. Taste as you go, since coconut aminos can change the overall balance.
