How to Make Chinese Beef and Onion Stir Fry Recipe
Step 1: Marinate the Beef
Start by tossing your thinly sliced beef sirloin with soy sauce, oyster sauce, and cornstarch in a medium bowl. This combination not only infuses flavor deeply into the meat but also tenderizes it, ensuring every bite is juicy and flavorful. Allow it to sit for at least 15 minutes—this step is the secret weapon behind that melt-in-your-mouth texture.
Step 2: Cook the Beef
Heat one tablespoon of vegetable oil in a wok or large skillet over medium-high heat. Add the marinated beef and stir-fry for 2 to 3 minutes, just until the edges brown but the center remains slightly undercooked. This quick searing locks in the juices and creates a caramelized crust. Once browned, remove the beef and set it aside to prevent overcooking.
Step 3: Stir-Fry the Aromatics and Onions
In the same skillet, pour in the remaining tablespoon of vegetable oil. Toss in your sliced onions, minced garlic, and chopped ginger. Stir-fry for 2 to 3 minutes until the onions soften and their natural sweetness comes forward, mingling beautifully with the fragrant garlic and sharp bite of ginger. This base builds the robust flavor backbone for the whole dish.
Step 4: Combine and Simmer
Return the browned beef to the skillet and sprinkle in the sugar and two tablespoons of water. Stir everything together and let it simmer for another 2 to 3 minutes, allowing the beef to finish cooking and the flavors to meld harmoniously. This step ensures the beef stays tender while the sauce begins to develop.
Step 5: Thicken the Sauce
Slowly add the cornstarch-water mixture to the pan while stirring continuously. This process thickens the sauce until it achieves a luscious, glossy consistency that clings to the beef and onions perfectly. Avoid adding too much at once so you retain a nice balance—neither too runny nor overly thick.
Step 6: Final Flavor Touches
Drizzle in the sesame oil for a wonderful fragrant finish, then season with salt and pepper to taste. Mix everything together thoroughly to combine all the layers of flavor. The addition of sesame oil at the end brightens the dish with a nutty depth that makes all the difference.
Step 7: Garnish and Serve
Take the skillet off the heat, sprinkle sliced green onions on top for a fresh pop of color and crunch, then serve immediately. The dish shines brightest when enjoyed hot from the pan alongside your favorite accompaniments.
How to Serve Chinese Beef and Onion Stir Fry Recipe

Garnishes
The obvious—and delicious—choice is fresh green onions; their crisp texture and mild oniony flavor elevate the dish’s presentation and taste. For an added layer of heat, sprinkle some toasted sesame seeds or a few chili flakes. These simple garnishes make your stir fry look and feel extra special without extra fuss.
Side Dishes
Steamed jasmine rice or fragrant basmati rice are classic partners to soak up the savory sauce of this stir fry. For a heartier meal, serve alongside stir-fried noodles or vegetable fried rice. You can also offer simple steamed or sautéed greens like bok choy or broccoli to add a refreshing vegetable crunch and vibrant color to the plate.
Creative Ways to Present
To impress guests, consider plating the stir fry over a bed of buttery mashed potatoes or cauliflower rice for a low-carb twist. For a fun family meal, place the stir fry in lettuce cups for interactive handheld bites. You might even sprinkle crushed peanuts or drizzle chili-garlic sauce on top to take this classic dish into exciting new flavor territories.
Make Ahead and Storage
Storing Leftovers
This Chinese Beef and Onion Stir Fry Recipe reheats beautifully, so store any leftovers in an airtight container in the refrigerator promptly. Try to consume within 2 to 3 days for optimal freshness and flavor. The tender beef and thickened sauce hold up well without becoming dry or mushy.
Freezing
If you want to save some for later, this stir fry freezes well. Cool it thoroughly, then transfer to freezer-safe containers or bags. Label with the date, and freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating gently to preserve texture and taste.
Reheating
Reheat leftovers in a skillet or wok over medium heat, adding a splash of water or broth if the sauce has thickened too much. Stir frequently until warmed through to maintain that fresh-from-the-wok texture. Avoid the microwave if possible to keep the beef tender and the sauce glossy.
FAQs
Can I use a different cut of beef for this stir fry?
Absolutely! While sirloin is ideal for its tenderness and quick cooking time, flank steak or skirt steak sliced thin against the grain will work just as well. The key is slicing thinly to ensure tender bites.
Is oyster sauce necessary in the Chinese Beef and Onion Stir Fry Recipe?
Oyster sauce adds a unique sweet and briny depth that balances the soy sauce’s saltiness. If you don’t have it on hand, you can substitute with hoisin sauce or a bit of fish sauce, but the flavor profile will slightly change.
How can I make this recipe spicier?
Great question! Add chili flakes when cooking the aromatics, or drizzle some sriracha or chili oil on the finished dish. Fresh sliced chili peppers tossed in during the stir-fry step also work wonderfully to ramp up the heat.
What’s the best way to slice beef for stir-fry?
Freezing the beef for about 30 minutes before slicing helps make thinner, more uniform slices. Always cut against the grain to shorten muscle fibers, resulting in tender pieces that cook quickly and stay juicy.
Can I replace the onions with another vegetable?
Onions provide a signature sweetness and softness, but you can experiment with thinly sliced bell peppers, leeks, or scallions. Just keep in mind that each will alter the flavor balance and texture of the dish slightly.
Final Thoughts
This Chinese Beef and Onion Stir Fry Recipe is a shining example of how a handful of simple, everyday ingredients can be transformed into an irresistible meal full of flavor and heart.

Ingredients
Beef Marinade
- 1 lb (450g) beef sirloin, thinly sliced against the grain
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon cornstarch
Stir Fry
- 2 tablespoons vegetable oil
- 2 medium onions, sliced
- 3 cloves garlic, minced
- 1 tablespoon ginger, finely chopped
- 1 teaspoon sugar
- 2 tablespoons water
- 1 tablespoon cornstarch mixed with 2 tablespoons water (to thicken sauce)
- 1 teaspoon sesame oil
- Salt and pepper to taste
- Green onions, sliced, for garnish
Instructions
- Marinate the Beef: In a medium bowl, combine the thinly sliced beef sirloin with soy sauce, oyster sauce, and cornstarch. Stir well to coat all pieces evenly and let it marinate for at least 15 minutes to develop flavor and tenderize the beef.
- Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef and stir-fry for 2-3 minutes until the beef is browned but still slightly undercooked. Remove the beef from the skillet and set aside to prevent overcooking.
- Stir-fry Aromatics and Onions: In the same skillet, add the remaining tablespoon of vegetable oil. Add the sliced onions, minced garlic, and chopped ginger. Stir-fry this mixture for 2-3 minutes until the onions soften and become fragrant, which builds the base flavor for the dish.
- Combine Beef and Seasonings: Return the partially cooked beef to the skillet with the onions. Add sugar and 2 tablespoons of water to the pan. Stir all ingredients together and continue cooking for another 2-3 minutes until the beef is fully cooked through and tender.
- Thicken the Sauce: Pour in the cornstarch and water mixture while stirring continuously. Cook for a minute or so until the sauce thickens, coating the beef and onions nicely with a glossy finish.
- Finish the Dish: Drizzle sesame oil over the stir-fry and season with salt and pepper to taste. Mix thoroughly to combine all the flavors evenly.
- Garnish and Serve: Remove the skillet from heat. Garnish the dish with freshly sliced green onions and serve immediately, ideally with steamed rice or noodles for a complete meal.
Notes
- Be sure to slice the beef thinly against the grain to ensure tenderness.
- Marinating the beef for longer than 15 minutes can enhance flavor and texture.
- If you prefer a spicier dish, consider adding sliced chili peppers or a splash of chili sauce during step 3.
- Use a well-seasoned wok or non-stick skillet to prevent sticking during stir-frying.
- For a gluten-free version, substitute soy sauce and oyster sauce with gluten-free alternatives.
