Teriyaki Glazed Beef Stir-Fry with Broccoli (30-Min Weeknight Dinner)

I started making this stir-fry on a Tuesday when I had a pound of flank steak in the fridge and exactly zero energy to do anything complicated. Thirty minutes later, my husband was asking if there was more. That's honestly the highest praise I get in this house, so I wrote it down immediately and have been making it almost every week since.

What makes this one work is the cornstarch coating on the beef before it hits the pan. I skipped that step the first time I made it and the beef came out chewy and the sauce slid right off. Coating the slices in cornstarch first gives you that slightly crisp exterior that actually holds the glaze — and the glaze itself is simple: soy sauce, honey, rice vinegar, and hoisin. No bottled teriyaki needed, and it comes together while the beef cooks.

My husband eats this over rice without thinking twice. Saad, who will reject anything with visible green things if he's in a mood, actually eats the broccoli here because it soaks up the sauce. I make a double batch on weeks when I know we'll want leftovers — reheated the next day, the sauce is even better because the flavors have had time to settle. If you like weeknight dinners that feel like more than weeknight dinners, you might also want to check out my Crockpot Salisbury Steak — it's that same idea of real comfort food without much fuss.

One thing to know before you start: this moves fast once the pan is hot. Have everything sliced, measured, and next to the stove before you turn on the heat. Stir-fry waits for no one, and if you're scrambling to find the soy sauce while the garlic is burning, you'll end up with bitter garlic and sad vegetables. Prep first, cook second. Ten minutes of prep, twenty minutes of cooking, done.

Why You'll Love This Recipe

• On the table in 30 minutes: I timed myself once — 12 minutes of prep, 18 minutes of actual cooking. That's faster than waiting for delivery, and I don't have to tip myself. On the nights I'm exhausted after school pickup, this is the dinner I reach for without even thinking about it.

• The homemade glaze is actually worth making: I know it's tempting to grab a bottle of store-bought teriyaki, and yes, you can do that in a pinch. But this sauce takes about two minutes to whisk together, and it's thicker, glossier, and less sweet than most bottled versions. Hoisin is the ingredient that makes it taste more complex than it should for how little effort it takes.

• One pan, minimal cleanup: The beef comes out, the vegetables go in, everything comes back together. I'm using my heavy 12-inch skillet the whole time — no wok required, though a wok works great if you have one. The fewer dishes I'm washing at 8pm, the better.

• Works with whatever vegetables you have: Broccoli is the base here, but I've thrown in snap peas, sliced mushrooms, and even baby corn when I had them. This is a great fridge-cleanout dinner — if it's a vegetable that can handle high heat and 4-5 minutes of cooking time, it'll work.

• Reheats well the next day: I almost like this better the next day, which isn't something I can say about most stir-fries. The sauce thickens up a little in the fridge, and when you reheat it with a splash of water it coats everything again. I make a double batch specifically so I have lunch covered the next day.

Ingredients

• 1 pound flank steak, thinly sliced against the grain
• 2 tablespoons cornstarch (for coating the beef)
• 2 tablespoons vegetable oil, divided
• 4 cups broccoli florets
• 1 red bell pepper, thinly sliced
• 3 cloves garlic, minced
• 1 tablespoon fresh ginger, grated (or 1 teaspoon ground ginger in a pinch)
• ¼ cup soy sauce (low-sodium works fine)
• ¼ cup water
• 2 tablespoons honey
• 2 tablespoons rice vinegar
• 1 tablespoon hoisin sauce (find it in the Asian aisle at Walmart or Kroger)
• 1 tablespoon cornstarch mixed with 2 tablespoons water (slurry for thickening)
• 1 teaspoon sesame oil
• 1 tablespoon sesame seeds, optional, for garnish
• 2-3 green onions, chopped, optional, for garnish

Directions

• Step 1: Coat the beef. In a medium bowl, toss the thinly sliced flank steak with the 2 tablespoons of cornstarch until every piece is lightly coated. This is the step I skipped the first time and regretted — the cornstarch creates a thin crust on the beef that keeps it tender inside and gives the sauce something to cling to.
• Step 2: Make the teriyaki glaze. In a small bowl, whisk together the soy sauce, water, honey, rice vinegar, and hoisin sauce until combined. In a separate tiny bowl, stir together the cornstarch and water to make your slurry. Set both bowls next to the stove — you'll need them fast once the cooking starts.
• Step 3: Cook the beef. Heat 1 tablespoon of the vegetable oil in a large heavy skillet or wok over medium-high heat until it shimmers. Add the beef in a single layer — cook in two batches if needed, because crowding the pan steams the beef instead of searing it. Cook 3-4 minutes, stirring occasionally, until browned. Remove the beef to a plate and set aside.
• Step 4: Cook the vegetables. In the same skillet, add the remaining tablespoon of oil. Add the broccoli, red bell pepper, garlic, and ginger all at once and stir-fry over medium-high heat for 4-5 minutes, until the broccoli is bright green and just tender but still has a little bite. Don't walk away — this goes quickly.
• Step 5: Bring it all together. Return the cooked beef to the skillet with the vegetables. Pour the teriyaki glaze over everything and toss to coat. Add the cornstarch slurry and stir for another 2-3 minutes until the sauce thickens and turns glossy. If it gets too thick, add a tablespoon of water and stir.
• Step 6: Finish and serve. Take the pan off the heat, drizzle the sesame oil over the top, and give it one last toss. The sesame oil goes in at the end so it doesn't burn off — it adds a nutty depth that changes the whole dish. Scatter sesame seeds and green onions over the top if you like, then serve immediately over steamed rice or noodles.

Tips for Success

• Slice the beef thin and against the grain: This is the difference between tender and chewy. Flank steak has long muscle fibers running through it — if you slice with the grain, those fibers stay intact and the meat is tough. Cut across them and each piece is short and easy to chew. If your steak is hard to slice thin, pop it in the freezer for 15-20 minutes first and it firms up enough to cut cleanly.

• Don't crowd the pan when cooking the beef: I learned this the hard way after my first attempt came out grey and steamy instead of browned. When you add too much meat to a hot pan at once, the temperature drops and the beef releases liquid instead of searing. Cook in two batches if your pan isn't huge — it takes an extra three minutes and it's completely worth it.

• Prep everything before you start cooking: Stir-fry happens fast. Once the pan is hot you're moving from one step to the next with maybe 30 seconds between them. If you're still mincing garlic when the beef is already in the pan, something will overcook. I spend 10 minutes getting everything ready — beef coated, sauce whisked, vegetables cut — before I even turn on the burner.

• Add the sesame oil at the very end: Sesame oil has a low smoke point, which means if you cook with it over high heat it burns and gets bitter fast. I use vegetable oil for the actual cooking and drizzle sesame oil over the finished dish right before serving. That way you get the full nutty fragrance without any bitterness.

• Adjust the sauce thickness with water or broth: The cornstarch slurry thickens the sauce quickly, and sometimes it goes faster than expected — especially if you're cooking over very high heat. If the sauce gets too thick and sticky before everything is coated, just add a tablespoon of water and stir it through. You can also add a splash of low-sodium chicken broth if you want the sauce a little thinner and savory.

Variations

• Chicken instead of beef: Thinly sliced chicken breast or thigh works really well here — thighs especially, because they stay juicier than breast meat over high heat. Use the same cornstarch coating method and cook 4-5 minutes until no longer pink. The glaze is the same, the technique is the same, and honestly my husband sometimes prefers the chicken version.

• Tofu for a vegetarian version: Use extra-firm tofu, press it well to remove as much moisture as possible, then cube it and coat in cornstarch. Pan-fry in oil until golden on all sides before adding the vegetables — this takes a bit longer than the beef, about 6-8 minutes total. The glaze works beautifully on tofu, and if you add extra broccoli and snap peas it becomes a really satisfying vegetarian dinner.

• Spicy version: Add ½ teaspoon of red pepper flakes to the glaze when you're whisking it together, or stir in a teaspoon of sriracha at the end. My husband always adds extra chili to his bowl anyway, so sometimes I keep the main batch mild and put a bottle of chili garlic sauce on the table for him to do as he likes.

• Peanut teriyaki: Whisk a tablespoon of creamy peanut butter into the glaze before cooking. It makes the sauce richer and slightly thicker, with a nutty undertone that works really well with the broccoli and beef. Finish with crushed peanuts instead of sesame seeds. This is not traditional at all — I know that — but it's genuinely good and something different when you've made the original version a dozen times.

• Different vegetables: Snap peas, thinly sliced carrots, baby bok choy, mushrooms, or zucchini all work here. Harder vegetables like carrots need a couple extra minutes; soft ones like mushrooms need less time than the broccoli. I've also made this with just whatever was left in the crisper drawer and it's always fine — this sauce is forgiving.

Serving and Storage

Serving

Serve this straight from the pan over steamed white rice — jasmine rice is my go-to because the fragrance works well with the glaze. Brown rice or noodles (soba or lo mein both work) are also good options. Garnish with sesame seeds and sliced green onions if you have them; they add a little freshness against the rich glaze. I usually put a small dish of chili garlic sauce on the table so everyone can adjust the heat themselves. In Pakistan we'd typically serve a saucy stir-fry like this with plain rice, but I've noticed my readers in the US and UK often like it just as much over noodles for a slightly different texture.

Storage

Leftovers keep in an airtight container in the refrigerator for up to 3 days. When reheating, add a tablespoon of water to the pan or bowl before microwaving — it loosens the sauce and keeps the beef from drying out. To freeze, let the stir-fry cool completely, then transfer to a freezer-safe container and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat on the stovetop over medium heat, adding a splash of water to refresh the sauce.

Frequently Asked Questions

Can I use store-bought teriyaki sauce instead of making the glaze?

Yes, and I've done it when I was really short on time. The homemade glaze takes about two minutes to whisk together and it's thicker and less sweet than most bottles, so I prefer it. But if you're reaching for the bottle on a busy night, use about ⅓ cup and skip adding extra water — most store-bought sauces are already quite thin. Still add the cornstarch slurry to help it thicken up in the pan.

How do I keep the beef from turning tough?

Two things matter most: slice it thin against the grain, and cook it over high heat quickly. Flank steak gets tough when it's overcooked or cut with the grain. Once the beef is browned — 3 to 4 minutes max — get it out of the pan. It finishes cooking when you return it to the sauce at the end, so you don't need it fully done in the first step.

Can I make this ahead of time?

You can do most of the prep ahead: slice the beef, coat it in cornstarch, store it covered in the fridge for up to 24 hours. You can also whisk the glaze and keep it in a small jar in the fridge. When it's time to eat, the actual cooking takes under 20 minutes. I don't recommend cooking the whole stir-fry ahead and reheating for guests — it's best fresh out of the pan, though it does reheat well for regular weekday lunches.

I don't have hoisin sauce — what can I substitute?

Hoisin adds a slightly sweet, fermented depth to the glaze. If you don't have it, you can leave it out and add an extra teaspoon of honey plus a tiny splash of Worcestershire sauce — it's not the same but it works. Oyster sauce is a closer substitute if you have that instead. Hoisin is pretty widely available in the Asian aisle at most US grocery stores, Walmart included, so it's worth keeping a bottle around.

How do I keep the broccoli from getting soggy?

High heat and not too long in the pan. I cook the broccoli for 4-5 minutes max — it should be bright green and just tender when you poke it with a fork, not soft. It continues cooking a little when the sauce goes in, so pull it slightly before you think it's done. Overcooked broccoli in a stir-fry turns mushy and loses that color, and nobody wants that.
