20-Minute Beef Teriyaki Stir Fry
Beef teriyaki stir fry is the kind of dinner that beats takeout in every way. It’s faster, fresher, and you get to control the sticky-sweet sauce.

This version comes together in about 20 minutes with a hot wok, thinly sliced steak, and a handful of vegetables. The homemade teriyaki sauce is dead simple, and the whole thing coats every bite in that glossy, savory glaze you actually want.
What Makes This Stir Fry a Weeknight Go-To
The sauce is the real secret. Equal parts soy sauce, mirin, and sake with a touch of brown sugar, simmered until it thickens just enough to cling to the beef and vegetables. It’s glossy and just sweet enough without tasting like candy.
The beef stays tender because you slice it thin across the grain and sear it hard and fast. Everything else goes into the same pan, so cleanup is minimal. It’s the kind of meal I make when I want something that tastes like a treat but takes less effort than chopping a salad.
Ingredients

- 1 lb flank steak or sirloin: sliced thin against the grain
- 1/4 cup soy sauce: use regular or low-sodium, whichever you have
- 1/4 cup mirin: Japanese sweet rice wine, not cooking mirin
- 2 tbsp sake: or dry sherry
- 1 tbsp brown sugar: light or dark both work
- 2 tbsp vegetable oil, divided: for searing and stir-frying
- 2 cups broccoli florets: about one small head
- 1 red bell pepper: sliced into strips
- 1/2 onion: sliced
- 1 cup snap peas: ends trimmed
- 2 garlic cloves: minced
- 1 tsp grated fresh ginger
- 1 tbsp cornstarch mixed with 1 tbsp water: for the slurry
Any crisp vegetable works well here. Try snow peas, carrots, or bok choy.
Variations / Substitutions
- Chicken or pork: Swap the beef for 1 lb boneless chicken thighs or pork tenderloin, sliced the same way.
- Gluten-free: Use tamari instead of soy sauce.
- No alcohol: Replace the sake with water or apple juice and increase the brown sugar by 1 teaspoon.
- Spicy: Add 1 teaspoon chili flakes or a squirt of sriracha with the sauce.
- Vegetarian: Use extra-firm tofu or sliced mushrooms and cook until golden before adding the vegetables.

How to Make Beef Teriyaki Stir Fry
Step 1: Mix the Teriyaki Sauce

In a small bowl, whisk together 1/4 cup soy sauce, 1/4 cup mirin, 2 tablespoons sake, and 1 tablespoon brown sugar until the sugar dissolves, about 30 seconds. Set the sauce aside while you prep the beef and vegetables.
The sauce will look thin at this stage but don’t worry. Once it hits the hot pan and thickens with the cornstarch, it turns into that shiny, clingy glaze you’re after. Taste it now. It should be salty, mildly sweet, and have a distinct teriyaki character.
Step 2: Sear the Beef

Heat a large wok or heavy skillet over high heat until very hot. Add 1 tablespoon of the vegetable oil and swirl to coat. Working in batches so the pan doesn’t crowd, add the sliced beef in a single layer. Let it sear without stirring for 1 minute, then stir-fry for another minute until the edges are browned but the centers are still a little pink. Transfer the beef to a plate.
The beef will finish cooking when you toss it with the sauce later, so pulling it now keeps it from turning tough. You want those dark, caramelized bits on the edges. That’s where the flavor is.
Step 3: Stir-Fry the Vegetables

Add the remaining 1 tablespoon oil to the pan. Toss in the 2 cups broccoli florets, sliced red bell pepper, sliced onion, and 1 cup snap peas. Stir-fry over high heat for 3 to 4 minutes, until the broccoli turns bright green and the vegetables are crisp-tender.
Push the vegetables to the edges of the pan. Drop the minced garlic and grated ginger into the center and let them sizzle for 30 seconds, then stir everything together. The fragrance at this point will be huge.
Step 4: Toss Everything with the Sauce

Return the seared beef and any accumulated juices to the pan. Pour in the teriyaki sauce and bring to a full boil. Stir in the cornstarch slurry and cook for 1 minute, until the sauce thickens and coats every piece of beef and vegetable in a glossy glaze.
You’ll see the sauce go from thin to shiny and sticky right before your eyes. Spoon the stir fry over steamed rice and serve immediately while everything is piping hot and the vegetables still have a little crunch.
A Few Tips for Stir Fry Success
- Get your pan genuinely hot before adding oil. The wok should smoke just slightly. That’s how you get the sear.
- Prep every ingredient before you turn on the stove. Stir-frying moves fast, and you won’t have time to chop once the heat is on.
- Don’t skip the mirin. It’s what gives teriyaki sauce its signature shine and balanced sweetness. Dry sherry can pinch-hit for sake, but mirin is non-negotiable.
- If your pan isn’t large enough, cook the beef in two batches. Overcrowding steams the meat instead of searing it.
Storing Leftover Stir Fry
- Refrigerate: Store leftovers in an airtight container for up to 3 days. The sauce keeps the beef moist.
- Reheating: Warm in a skillet over medium heat with a splash of water to loosen the sauce, or microwave in 30-second bursts until hot. The vegetables will soften a bit but still taste great.
What to Serve With Beef Teriyaki Stir Fry
Steamed jasmine rice is the obvious and best partner. It soaks up every drop of the teriyaki glaze. For a lighter contrast, add a cucumber salad dressed with rice vinegar and a pinch of salt. Toasted sesame seeds and sliced green onions on top add a fresh, nutty finish.
Frequently Asked Questions
Can I make the teriyaki sauce ahead of time?
Yes. Whisk the soy sauce, mirin, sake, and brown sugar together and refrigerate for up to 2 days. Give it a quick stir before using.
Why isn’t my sauce thickening?
A cornstarch slurry only thickens when it comes to a full boil. Make sure the sauce is bubbling vigorously for at least 1 minute after adding the slurry, and that you didn’t skip the slurry step.
How do I slice beef thinly for stir fry?
Partially freeze the steak for 15 to 20 minutes first. Then use a sharp knife to cut thin strips across the grain. The cold, firm meat gives you better control.
Can I use bottled teriyaki sauce instead?
You can, but homemade lets you dial in the sweetness and salt exactly the way you like it. Bottled sauces are often much sweeter and thicker.
