Ingredients You’ll Need
The beauty of this Chinese Beef and Onion Stir-Fry Recipe lies in its simplicity—each ingredient is straightforward but essential, adding layers of flavor, texture, and color that make the dish shine. Gathering them is easy, and all contribute to a perfectly balanced meal.
- 1 pound flank steak or sirloin, thinly sliced against the grain: This gives you tender, juicy beef that cooks quickly and evenly.
- 2 tablespoons vegetable oil (or sesame oil): Adds the perfect amount of fat for cooking while infusing subtle nutty notes if sesame oil is used.
- 1 medium onion, thinly sliced: Brings sweetness and a soft texture after gentle caramelization.
- 2 cloves garlic, minced: Infuses aromatic depth and a subtle pungency.
- 1/4 cup soy sauce (low-sodium recommended): Offers salty umami that ties the dish together.
- 2 tablespoons oyster sauce: Contributes rich savory complexity and a touch of sweetness.
- 1 tablespoon hoisin sauce: Adds a fragrant, slightly sweet dimension to the sauce.
- 1 tablespoon rice vinegar: Balances richness with a slight tangy brightness.
- 1 tablespoon brown sugar: Helps caramelize the onions and deepens the overall flavor.
- 1/2 teaspoon ground black pepper: Provides warm, gentle heat.
- 1/4 teaspoon red pepper flakes (optional, for heat): Adds a subtle kick for those who love spice.
- 2 teaspoons cornstarch mixed with 2 tablespoons water (for thickening): Creates that glossy, luscious sauce consistency.
- 2 green onions, sliced (for garnish): Adds freshness and a pop of color on top.
- Cooked rice (for serving): Completes the meal by soaking up every bit of sauce.
How to Make Chinese Beef and Onion Stir-Fry Recipe
Step 1: Prepare and Cook the Beef
Start by heating 1 tablespoon of vegetable or sesame oil in a large skillet or wok over medium-high heat. Add the thinly sliced beef and cook for about 3 to 4 minutes until it’s beautifully browned and cooked through. Searing the beef properly ensures it stays juicy and full of flavor. Once done, remove the beef and set it aside—don’t worry, we’re coming back to it soon.
Step 2: Caramelize the Onions
In the same skillet, pour in the remaining tablespoon of oil. Add the sliced onions and cook for 5 to 6 minutes, stirring occasionally. You want your onions softened and lightly caramelized because their natural sugars will bring that sweet depth which balances the savory beef perfectly. This step is key, so be patient and let the onions do their magic.
Step 3: Add Garlic and Create the Sauce
Once the onions are just right, toss in the minced garlic and stir for 1 minute until fragrant. Garlic is such a simple ingredient but packs a punch in flavor. Then, whisk together your soy sauce, oyster sauce, hoisin sauce, rice vinegar, brown sugar, black pepper, and optional red pepper flakes in a small bowl. Pour this sauce over the garlic and onions, allowing all those fantastic flavors to mingle and infuse.
Step 4: Combine Beef and Thicken the Sauce
Now, return the cooked beef to the skillet, gently tossing it with the sauce and onions. Add any juices that have collected from the beef to boost flavor. Next, stir in your cornstarch-water mixture and cook for 1 to 2 more minutes. This makes the sauce luxuriously thick and glossy, clinging to every tender slice of beef and sweet onion. That glossy finish? It’s what makes this Chinese Beef and Onion Stir-Fry Recipe such a joy to eat.
Step 5: Final Touches and Serve
Remove from heat, garnish with those vibrant green onions for a fresh crunch and color pop, then serve hot over a bed of fluffy cooked rice. The rice is perfect for soaking up every bit of sauce, making each bite irresistibly satisfying.
How to Serve Chinese Beef and Onion Stir-Fry Recipe

Garnishes
Freshly sliced green onions are classic and add brightness, but feel free to sprinkle toasted sesame seeds or finely chopped cilantro for an extra layer of aroma and texture. A wedge of lime on the side can brighten up the dish even more with a squeeze of juice just before eating.
Side Dishes
This stir-fry shines on its own over steamed white or jasmine rice. For a more varied meal, pair it with stir-fried greens like bok choy or snap peas, or go for a crunchy Asian slaw. Light, crisp sides help balance the rich, savory beef and sweet onions beautifully.
Creative Ways to Present
Looking to impress at dinner parties? Serve the Chinese Beef and Onion Stir-Fry Recipe in mini lettuce cups for a fresh handheld option. Alternatively, pile it over noodles or use it as a filling in steamed bao buns for a fun twist that will have everyone asking for your secret.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftover stir-fry to an airtight container and refrigerate. It will stay fresh and delicious for up to 3 days, making it a perfect ready-to-go meal for busy days.
Freezing
If you want to store it longer, you can freeze the stir-fry for up to 2 months. Make sure to use a freezer-safe container and leave a little room for expansion. Thaw overnight in the fridge before reheating.
Reheating
Warm your leftovers gently in a skillet over medium heat with a splash of water to loosen the sauce if needed. Avoid microwaving on high to keep the beef tender and the sauce from drying out. Reheating on the stovetop keeps the textures and flavors closest to freshly made.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While flank steak or sirloin is ideal for tenderness and quick cooking, you can also use ribeye or skirt steak. Just be sure to slice thinly against the grain for best results.
Is it possible to make this stir-fry gluten-free?
Yes! Swap the soy sauce and oyster sauce for gluten-free versions, which are widely available. This way, you keep all the amazing flavors without compromising dietary needs.
How do I get the onions soft but not mushy?
Cook them slowly over medium heat, stirring occasionally, until they are translucent and lightly caramelized. This usually takes about 5 to 6 minutes and keeps them tender yet with a bit of bite.
Can I prepare any parts of this recipe in advance?
You can slice the beef and onions ahead of time and keep them refrigerated for up to a day. Mix your sauce ingredients in advance too—that way, dinner cooks up super fast.
What should I do if my sauce is too thick or too thin?
If the sauce gets too thick, simply add a splash of water or broth to loosen it. If it’s too thin, stir in a bit more cornstarch mixed with water and cook until it thickens to your liking.
