Beef and Onion Stir Fry

Anne Rose
This beef and onion stir fry is the weeknight Chinese-style dinner I make when I want tender, juicy beef and a pile of sweet onions in oyster sauce — without babysitting the stove.
The method is simple: slice the beef against the grain, give it a short baking-soda marinade, fry the onions just until they lose their raw bite, then sear the beef hot and finish the sauce in the same pan. The whole cook is about ten minutes once the prep is done.

Recommended
Wok
High heat, room to toss, and a spatula that actually gets under the beef — this is what makes a stir fry sear instead of steam.

Optional
Deep Skillet
A sturdy deep skillet (with a lid) is perfect if you don’t have a wok — great for searing the beef and finishing the onions in one pan.

Optional
Garlic Peeler
This recipe goes heavy on garlic — a silicone peeler gets cloves ready fast with no sticky fingers.

Food Chopper
I bought this because I was sick of crying every time I chopped onions — and spending forever on prep. It saves so much time. Great investment.

Serving Suggestions
Spoon the beef and onion stir fry over hot jasmine rice while the sauce is still glossy. Extra green onion greens, chili oil, or a fried egg on the side all work if you want it heartier. It’s a full plate on its own — no extra sides required on a weeknight.
Storing & Reheating
Cool leftovers within about an hour, store in an airtight container, and use within 3–4 days. The onions soften in the fridge, so this is best the night you cook it.
Reheat quickly in a hot skillet with a splash of water so the sauce loosens. Don’t microwave it dry — the beef tightens up. Freeze only if you have to; thaw overnight and re-sear briefly.
Substitution Tips and Recommendations from Our Audience
This beef and onion stir fry is built to flex — here are the swaps that work especially well:
-
Swap the cut: Flank, sirloin, or ribeye all work if you slice thin against the grain. Chicken thigh uses the same marinade and cook times.
-
No oyster sauce? Use extra soy sauce plus a pinch of sugar, or a mushroom-based vegetarian oyster sauce. No Shaoxing? Dry sherry, or skip the wine and add a splash more water.
-
Add peppers: Toss in sliced bell pepper with the onions if you want a beef, pepper, and onion stir fry — same sauce, same timing.
-
Serve it with rice: Day-old jasmine rice on the side is the easy plate. Fresh rice works here because you’re not frying it in the pan.
Frequently Asked Q's
Quick answers on the cut of beef, how this stir fry stays tender, and what to use if you’re out of oyster sauce.
Q: What cut of beef is best for beef and onion stir fry?
Flank, sirloin, or ribeye — whatever you can slice thin against the grain. The marinade does the tenderizing, so you don’t need an expensive steak.
Q: How does the beef stay tender and juicy?
Slice against the grain, then marinate with baking soda and cornstarch before the oils go in. Sear hot and don’t overcook — the sauce finishes the beef in the pan.
Q: What can I use instead of oyster sauce?
Extra soy sauce plus a pinch of sugar, or a mushroom-based vegetarian oyster sauce. The stir fry will still be savory — you’ll just miss a little of that deep, glossy finish.
