Ingredients for Chinese Beef and Onion Stir-Fry
For the Beef Marinade:
- 1 lb flank steak or sirloin, thinly sliced against the grain
- 1 tablespoon soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon hoisin sauce
- 1 tablespoon cornstarch
- 1 tablespoon Shaoxing wine or dry sherry (optional, for extra depth of flavor)
- 1 teaspoon sesame oil
For Stir-Frying:
- 2 tablespoons vegetable oil
- 1 large yellow onion, halved and thinly sliced
- 2 cloves garlic, minced
- 1/2 teaspoon sugar (to balance the savory flavors)
- 2 green onions, chopped (optional, for garnish)
- Cooked white rice, for serving

This combination of ingredients will create a stir-fry with perfectly cooked beef, sweet and savory onions, and a hint of umami from the sauces.
Step-by-Step Instructions for Chinese Beef and Onion Stir-Fry
Now that we have the ingredients, let’s walk through the steps to create this mouth-watering dish.
1. Marinate the Beef
To ensure that the beef is flavorful and tender, we start by marinating it. In a bowl, toss the thinly sliced flank steak or sirloin with the following ingredients:
- Soy sauce
- Oyster sauce
- Hoisin sauce
- Cornstarch
- Shaoxing wine (if using)
- Sesame oil
Once all the ingredients are mixed in, let the beef marinate for at least 15 minutes. This will allow the beef to absorb the flavors of the marinade and become more tender. If you’re short on time, you can marinate it for even less time, but the longer you let it sit, the more flavorful it will be.
2. Sear the Beef
Once your beef is marinated, it’s time to sear it. Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat. Add the marinated beef to the pan in a single layer. Be sure not to crowd the pan, as this will prevent the beef from searing properly.
Sear the beef for about 1–2 minutes per side, until it’s browned but not overcooked. You want it to stay tender and juicy. Once seared, remove the beef from the pan and set it aside.
3. Stir-Fry the Onions
Now that your beef is seared, it’s time to stir-fry the onions. Add the remaining 1 tablespoon of vegetable oil to the same skillet. Add the thinly sliced yellow onions and stir-fry for about 3–4 minutes, until they start to soften and char slightly. The caramelization of the onions will add an extra layer of flavor to the dish.
Add the minced garlic and sugar to the skillet and stir for another 30 seconds. The sugar helps balance the savory flavors and adds a touch of sweetness that complements the onions.
4. Combine the Beef and Onions
Once the onions have softened and become fragrant, it’s time to combine the beef with the onions. Return the seared beef to the skillet and toss everything together. Stir the mixture for about 1 minute, ensuring that the beef and onions are well combined and heated through.
This is the final step before serving, so be sure to adjust the seasoning with extra soy sauce or hoisin sauce if needed, according to your taste preferences.
5. Serve
Once everything is combined and heated through, it’s time to serve your Chinese Beef and Onion Stir-Fry. Garnish with chopped green onions for an extra touch of freshness and crunch. Serve the stir-fry hot over cooked white rice for a complete meal.
Tips for the Perfect Chinese Beef and Onion Stir-Fry
Here are some helpful tips to make sure your Chinese Beef and Onion Stir-Fry comes out perfectly every time:
- Slice the Beef Thinly: To ensure the beef cooks quickly and remains tender, slice it thinly against the grain. This will help break down the muscle fibers and keep the beef soft.
- Use High Heat: Stir-frying is all about cooking quickly over high heat. Make sure your skillet or wok is preheated before adding the beef and vegetables.
- Don’t Overcrowd the Pan: When searing the beef, make sure not to overcrowd the pan. If necessary, cook the beef in batches to achieve a perfect sear.
- Add More Veggies: Feel free to add extra vegetables like bell peppers, snap peas, or broccoli to the stir-fry for added texture and nutrition.
