Ingredients You’ll Need
The magic of this Beef Onion Stir-fry Recipe lies in its straightforward yet thoughtfully chosen ingredients. Each one plays a starring role—bringing tenderness, depth, and a beautiful balance of sweet and savory flavors to every mouthful.
- Flank steak (1 pound, thinly sliced against the grain): This cut is perfect for quick stir-frying and stays juicy and tender when sliced properly.
- Soy sauce (2 tablespoons): Adds salty, savory depth and helps tenderize the beef during marination.
- Oyster sauce (1 tablespoon): Brings a subtle sweetness and glossy finish to the sauce.
- Cornstarch (1 tablespoon): Coats the beef, locking in moisture and helping the sauce cling beautifully.
- Vegetable oil (2 tablespoons): Neutral in flavor, it allows the aromatics and beef to shine while providing the perfect stir-fry sizzle.
- Yellow onion (1 large, sliced): The star vegetable here; it sweetens as it cooks, pairing perfectly with the savory beef.
- Garlic (2 cloves, minced): A must for that unmistakable stir-fry aroma and punch of flavor.
- Fresh ginger (1 tablespoon, minced): Brings a peppery brightness and warmth that elevates the entire dish.
- Rice vinegar (1 tablespoon): Adds a gentle tang that balances out the richness and lifts the flavors.
- Hoisin sauce (1 tablespoon, optional): For a touch of sweetness and complexity—highly recommended if you have it.
- Sesame oil (1 teaspoon): Just a drizzle at the end imparts an irresistible nutty fragrance.
- Green onion (1, sliced for garnish): Adds a fresh, colorful crunch to finish your plate.
- Freshly ground black pepper (to taste): For a subtle kick and to round out the flavors.
How to Make Beef Onion Stir-fry Recipe
Step 1: Marinate the Beef
Start by placing your thinly sliced flank steak in a mixing bowl. Add the soy sauce, oyster sauce, and cornstarch. Give everything a good mix—your hands are the best tool here! Let the beef marinate for at least 15 minutes. This little window of time is crucial: it tenderizes the beef and infuses it with the savory flavors that make this Beef Onion Stir-fry Recipe so irresistible.
Step 2: Sear the Beef
Heat one tablespoon of vegetable oil in a large skillet or wok over high heat. Once the oil is shimmering, toss in the marinated beef. Stir-fry for about 2 to 3 minutes—just until the pieces are browned on the outside but not fully cooked through. Remove the beef and set it aside. This quick sear locks in the juices and sets up that signature stir-fry texture.
Step 3: Stir-fry the Onions and Aromatics
Add the remaining tablespoon of oil to the hot pan. Throw in the sliced yellow onion and let it cook for 2 to 3 minutes, stirring often, until it’s softening but still a little crisp. Add the minced garlic and ginger and stir for another 30 seconds, just until fragrant. This step fills your kitchen with mouthwatering aromas and deepens the flavor base.
Step 4: Combine and Finish
Return the beef (with any juices) to the pan. Add the rice vinegar and hoisin sauce if you’re using it. Give everything a good toss for another 2 to 3 minutes until the beef is fully cooked and the sauce has thickened and coats every bite. Drizzle in the sesame oil and toss once more. Finish with cracked black pepper and adjust seasoning to taste.
Step 5: Garnish and Serve
Turn off the heat and sprinkle the sliced green onion over the top for a burst of color and crunch. Serve your Beef Onion Stir-fry Recipe hot, straight from the wok, ideally over a bed of steamed rice to soak up all that delicious sauce.

Garnishes
A final flourish of freshly sliced green onion brings a pop of color and a gentle bite. For extra flair, you can also sprinkle toasted sesame seeds or a pinch of chili flakes. Each garnish adds a new dimension, making every plate of Beef Onion Stir-fry Recipe look as good as it tastes.
Side Dishes
This dish loves company! Steamed jasmine or brown rice is the classic partner, perfect for catching every drop of sauce. If you want to lighten things up, pair with a crisp cucumber salad or sautéed bok choy. Even a quick miso soup makes for a delicious, well-rounded meal.
Creative Ways to Present
For a modern twist, spoon the stir-fry into lettuce wraps for a fresh, hand-held appetizer. Or, serve your Beef Onion Stir-fry Recipe over rice noodles for a fun departure from the usual. Little touches like these make dinner feel extra special, whether it’s a weeknight or you’re entertaining friends.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, let them cool completely before transferring to an airtight container. The Beef Onion Stir-fry Recipe will keep in the refrigerator for up to three days, and the flavors actually deepen as it sits—making tomorrow’s lunch something to look forward to!
Freezing
To freeze, portion the cooled stir-fry into freezer-safe bags or containers. Squeeze out as much air as possible to prevent freezer burn. It will stay delicious for up to two months. Thaw overnight in the fridge for best results before reheating.
Reheating
For best texture, reheat the stir-fry in a hot skillet over medium-high heat, adding a splash of water or broth if the sauce has thickened too much. A microwave also works for convenience—just cover loosely and heat in short bursts, stirring in between. This keeps the beef tender and the onions just right.
FAQs
Can I use a different cut of beef?
Absolutely! While flank steak is ideal for its tenderness, skirt steak or sirloin work wonderfully too. Just be sure to slice thinly against the grain for that melt-in-your-mouth texture in your Beef Onion Stir-fry Recipe.
What if I don’t have hoisin sauce?
No worries—hoisin sauce is optional. If you skip it, your sauce will be a little less sweet and complex, but still delicious. You could add a teaspoon of brown sugar or a dash of extra soy sauce for a similar effect.
Is this recipe gluten-free?
It can be! Simply use gluten-free soy sauce and hoisin sauce (if using) to make your Beef Onion Stir-fry Recipe suitable for gluten-free diets. Always check labels to be sure.
Can I add other vegetables?
Definitely. Bell peppers, snap peas, or broccoli would all be fantastic additions. Just add them to the pan with the onions and adjust cooking time as needed for your perfect veggie crunch.
How do I slice the beef thinly?
For paper-thin slices, place the steak in the freezer for about 30 minutes before slicing. Use a sharp knife and cut against the grain—this ensures tender bites in every forkful of your Beef Onion Stir-fry Recipe.

Instructions
- Marinate the Beef: In a bowl, combine the thinly sliced flank steak with soy sauce, oyster sauce, and cornstarch. Mix thoroughly ensuring the beef is well coated. Let it marinate for at least 15 minutes to absorb the flavors and tenderize.
- Cook the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat until hot. Add the marinated beef and stir-fry quickly for 2–3 minutes until the beef turns brown but is not fully cooked through. Remove the beef from the skillet and set aside to prevent overcooking.

Stir in the minced garlic and ginger, cooking for another 30 seconds to release their fragrance without burning.
- Combine and Finish Cooking: Return the partially cooked beef to the skillet with the onions, garlic, and ginger. Add the rice vinegar and hoisin sauce if using. Stir well to combine all ingredients. Continue stir-frying for another 2–3 minutes until the beef is fully cooked and the sauce slightly thickens, coating the ingredients beautifully.
- Add Finishing Touches and Serve: Drizzle sesame oil over the stir-fry and toss to evenly coat. Season with freshly ground black pepper as desired. Garnish with sliced green onions for freshness and color. Serve the stir-fry hot with steamed rice for a complete meal.
